T070-400V3A) is a horizontal-axis machine tool for machining metallic materials through cold removal of shaving (chips). Cutting is produced by movement of the piece being machined (which rotates on its own axis), and by the feed motion of the tool. Machine operation is fully manual, in that it can execute only movements upon direct command by the operator. 4.1 Expected use and field of application m o The machine is designed and built for accomplishing the following machining processes on all sorts of ferrous metallic materials:  Cylindrical turning;  Conical turning;  Facing;  Profiling;  Drilling;  Boring;  Threading;  Cutting / Cropping (of bar). v r c .i Expected use and materials The machine is designed and built for the specified use. Any different use, and deviation from the technical parameters established by the Manufacturer, may set a condition of danger to operators; therefore, the Manufacturer will not assume any responsibility for the possibly resulting damages. e f The Lathe is supplied with its own support base and it must be installed and utilized on flat surfaces, with adequate characteristics of ergonomics and strength. The Lathe can operate in closed work environments (production departments, halls, etc.), namely sheltered from weather conditions, and where there are no dangers of fire or explosion. Usage temperature range is of –10°C to +50°C. The environment must also be sufficiently lit in order to assure operation under maximum safety (at least 200 lux are recommended). Page 12 of 73 MACHINES & ACCESSORIES The Lathe consists of two fundamental groups (see Figure 2):  the spindle shaft assembly;  the sliding tool-holder assembly. The former is constituted by the spindle, to which the piece being machined is made integral, and by the spindle motor and its power transmission. The latter is formed by the parts that transmit the motion to the slides that guide the tool in its feed and approach movement to the piece. m o c .i Figure 2 – Characteristic fundamental groups of the parallel lathe. e f v r Page 13 of 73 MACHINES & ACCESSORIES 4.2 Description of the main parts 1 Brake 9 Spindle guard 17 Tailstock handwheel 2 Base 10 Halogen lamp 18 Support of bars 3 Bed 11 Turret 19 Lead screw 4 Speed sel. switches 12 Coolant hose 20 Turning bar 5 Side cover 13 Longitudinal turret travel 21 Lathe switch-on lever 6 Feed selector levers 14 Nonius 22 Tray 7 Electric controls 15 Tailstock block 23 Lead screw engagement lever 8 3-jaw spindle 16 Guides 24 Digital display 9 8 10 4 5 3 11 12 13 v r 7 6 m o c .i 24 e f 1 2 23 22 14 15 17 16 18 21 20 Figure 3 – Main parts of the precision parallel lathe. Page 14 of 73 19 MACHINES & ACCESSORIES 4.2.1 Carrier base The base bed (item 3 in Figure 3) is made of cast-iron; the casting was stabilized to avoid torsions and/or deformations caused by internal tensions of the material. At the upper part there are prismatic guides that assure movement and alignment of the drive headstock with the carriage and the mobile head (tailstock). The guides are hardened and ground. They have stiffening ribs which increase their rigidity. 4.2.2 Headstock and Spindle The headstock is made of high-strength cast iron; moreover, its interior has two protrusions that increase rigidity, thus reducing vibrations when machining at high speed. The various spindle speeds are obtained by means of a gear speed change (see also paragraph 4.2.3 below). The spindle (see Figure 4) is installed on the shaft of the headstock, and it is supported by two precision bearings. It is of self-centring type, with three jaws that allow locking the piece stably and safely. For closing / opening the jaws, it is necessary to insert the special wrench in the square-section housings located on the outer profile of the spindle. A more detailed explanation is given in section 10 of this manual. m o c .i Figure 4 – Spindle. The dangerous zone, in proximity of the spindle, is protected by an interlocked mobile guard (re. 9 in Figure 3), consisting of a metal sheet shield with safety micro-switch. 4.2.3 v r Spindle speed adjustment levers The panel for adjusting the spindle rotation speed (see Figure 5), is located on the left hand side of the machine, between the spindle and the feed speed change gearbox. It is equipped with two levers for selecting the desired rotation speed, as a function of the type of machining and of material. 4.2.4 e f Figure 5 – Speed adjustment levers. Feed speed adjustment panel The control panel for setting the spindle rotation speed (see Figure 6) is located on the left hand side of the machine, under the spindle speed adjustment panel. The lathe is provided with gears capable of assuring a considerable variety of feeds and threads (metric and in inches). The pitches are selected on four knob-type rotary selector switches that operate the speed change gears. A fifth knob selects the carriage feed direction. Figure 6 – Speed adjustment. Page 15 of 73 MACHINES & ACCESSORIES 4.2.5 Tool-holder carriage The carriage, which slides along the guides of the bed, is used for fixing the tool and transmitting to it the positioning and feed motions. The various parts (see Figure 7) are made of cast-iron, with hardened and ground guides that assure a high stability. The carriage is equipped with an independent system that assures lubrication of the moving parts. The carriage feed handwheels and the levers are easily reached and easy to use. m o Figure 7 – Toolholder carriage. 4.2.6 Mobile tailstock The tailstock assembly (see Figure 8) consists of a cast-iron body which assures rigidity and stability under every condition of use. The body of the tailstock is equipped with a locking system on the guides of the lathe, with lever. An adjustment screw provides the axial alignment of the tailstock. Inside there is the steel sleeve. Its movement occurs by means of a handle which is equipped with a nonius. 4.2.7 Rests v r c .i Figure 8 – Tailstock. In drilling, boring and facing operations, the tailstock cannot be utilized for securing the piece being machined. On the other hand, if a piece is long and heavy, it is not sufficient to use only a self-centring spindle, but it is necessary to secure one end of the piece by means of a fixture called rest. Two rests are provided: fixed rest and follower rest. e f Page 16 of 73 MACHINES & ACCESSORIES 4.2.8 Electric control panel 1 2 3 4 5 6 m o A B Figure 9 – Electric controls Figure A (1) GREEN PILOT LAMP: when lit, it indicates that power supply is on.

Figure B Master switch with safety key (padlock). v r c .i Motor speed selector switch This switch is located on the front part of the machine, under the controls for selecting the lathe operating modes. With the switch turned rightward, the motor will run at 1450 rpm. Turned leftward, it will run at 2850 rpm. I = 1450 II = 2850 e f Figure 10 – Motor speed selector switch. Spindle speed adjustment Upon turning the motor speed selector switch from position I to position II (or vice versa), spindle rotation will stop immediately. For restarting the machine, it is necessary to move the start/reversal lever to neutral, and then upward or downward (depending on the desired rotation direction). The spindle will not restart automatically. Page 17 of 73 MACHINES & ACCESSORIES 4.2.9 Pedal brake The machine is equipped with a mechanical brake which is actuated by a pedal. In case of need, pressing the pedal will slow down or stop completely spindle rotation (depending on how long the pedal is pressed). By releasing one’s foot from the pedal, the braking action ceases. m o Figure 11 – Emergency Brake. 4.2.10 c .i Lever for starting or reversing the spindle rotation The lever located on the right hand side of the base permits starting the spindle rotation or reversing the spindle rotation direction. When the lever is in central position “0”, the spindle will not rotate. By moving the lever downward the spindle will rotate clockwise; upward, anticlockwise (the machine rotation direction is influenced by the connection of the phases). v r e f Page 18 of 73 Figure 12 – Reversal lever.

It assures against the danger of undesired and/or accidental starts of the machine: switch-on can take place only through a voluntary action for the purpose, by a person who is in possession of the padlock key. The machine has also a mushroom-head emergency stop pushbutton. In case of an emergency, upon pressing this button the dangerous functions will stop. The electric control panel is supplied, through the built-in transformer, by direct current at 24V: this minimizes the danger of electrocution. The connection of the Lathe to the electric mains must be earthed, according to the applicable rules. m o c .i Electric shock A wrong connection and/or earthing of the Lathe can generate the risk of electric shocks. It is recommended to apply circuit breaker to the electric supply line. For detailed information, please contact your trusted electrician. If you haven’t understood well the earthing instructions, or if you are in doubt as to the exact machine earthing, please make a check together with a qualified electrician. v r e f Page 20 of 73 MACHINES & ACCESSORIES 5.2 “Mechanical” safety devices PROTECTION SHIELDS Guards, shields or aprons have the task to protect the operator, preventing coolant liquid, shavings, chips, tool fragments or even the piece being machined – which might get detached – to be thrown onto your face or breast. Shields may be either mobile or fixed (see Figure 14). 1 2 m o c .i Figure 14 – Position of protection shields. 1 Gearbox shield (fixed); 2 Spindle shield (mobile and interlocked). v r Mobile interlocked guards are provided with adequate safety switches, incorporated in the control system of the machine (electric circuit), so that opening the mobile shield will trigger the stop of the spindle and of the dangerous moving parts. e f Check the safety devices   Whenever you are going to use the Lathe, check for perfect functioning and position of the safety devices. In case of failures and/or breaks, don’t use the machine. PEDAL BRAKE The machine is equipped with a mechanical brake actuated by a pedal which, in case of need, allows spindle rotation to be slowed down or stopped completely (item 1 in Figure 3).

Displace the machine without using suitable hoisting/handling means. e f v r c .i Page 23 of 73 MACHINES & ACCESSORIES 7 LIFTING, TRANSPORT AND STORAGE 7.1 Lifting For hoisting the Lathe, proceed as follows: 1. For achieving a perfect balance, displace the tailstock to its stroke end at the right hand side of the bed, and secure it solidly by means of the locking lever; 2. Similarly, slide the tool-holder carriage until the machine (its weight) is perfectly balanced. m o Cleaning the sliding guides Don’t displace the tool-holder carriage and/or the tailstock before having cleaned their sliding guides. 3. For hoisting, use lifting accessories (ropes, steel cables or chains) of sufficient length and capacity and in good condition. Minimum recommended capacity: ~700 kg. 4. Sling the Lathe at its two ends, by passing the lifting accessories under the bed. c .i Risk of breaking the sliding guides v r Make sure the lifting accessories don’t touch the sliding guides and the lead screw, which might get damaged irreparably. 5. Insert the hook of the hoisting apparatus (crane, overhead travelling crane, etc.) at the middle of the lifting accessories (between the two ends), and lift slowly without jerks. e f The Manufacturer waives any and all responsibility regarding possible damage to persons and/or things, arising from a wrong lifting of the machine executed by unsuitable personnel, with inadequate lifting means and without following the indications and the operating procedures described in this manual. 7.2 Transport The machine can be transported on a truck or other vehicle of sufficient carrying dimensions and capacity. The machine must be duly secured to the transport means (for instance by means of ropes). During transport, the machine must be protected from rain, snow, hail, wind and any other possible adverse atmospheric condition. For the purpose, the means of transport should be closed-body (van, covered truck, etc.); alternatively, the machine should be covered with a waterproof canvas. Page 24 of 73 MACHINES & ACCESSORIES 7.3 Storage Should the machine have to be stored and preserved for a certain period before being installed and started up, for avoiding its damage and/or deterioration proceed as follows: 1. Detach the electric power supply cable; 2. Protect the machined parts (such as the guides, the carriage and the tool-holder slides, the spindle, the tailstock sleeve, etc.) with protective liquid and/or grease; 3. Keep the machine in a dry place, protected from dust and contaminant agents. Recommended climatic conditions for storage: Temperature: -15°C to +55°C; Humidity: 95% (in absence of condensation). m o Protection from impacts Make sure the Lathe is preserved from strikes and vibrations. e f v r c .i Page 25 of 73 MACHINES & ACCESSORIES 8 INSTALLATION AND START-UP 8.1 The installation place For installing the machine, choose a well lit area, away from sources of dampness and of vibrations. The Lathe must be positioned with adequate spaces remaining available to the operator, so that he can use it to its maximum potential and be able to carry out the adjustment, maintenance and cleaning operations unhindered and in all safety. For this purpose, a free area of at least two square metres must be left in front of the machine. m o Don’t install the machine outdoors If installed outdoors, the machine will suffer deformations, loss of functionality and damage to its electric circuit. c .i 8.2 Support base It is essential that the machine is positioned on a bearing surface which is uniform, flat and sufficiently strong to hold it steady under every condition that may occur during its normal use. v r Loss of stability Install the Lathe on a solid and resistant bearing surface, in order to prevent it from tipping over and causing vibrations. e f For assuring excellent stability and levelling results, and for minimizing vibrations, the machine should be fixed by means of metal feet with threaded stem and rubber base. As to the dimensions and positions of the support points, where to put these feet, see Figure 16. Page 26 of 73 MACHINES & ACCESSORIES m o c .i Figure 16 – Dimensions and fixing points. v r 8.3 Levelling the machine For this operation, a precision level (0.001 mm) should be used. 8.3.1 Preliminary phase The preliminary phase has the purpose to eliminate the presence of torsions at the bed of the lathe. The procedure is: zero set the headstock by adjusting the special screws for this; then lock the tailstock by means of its adjustment screw by bringing the reference mark to zero position. 8.3.2 e f Transversal levelling of the bed Put, in transversal direction, the level on the guides under the spindle and check the air bubble. Put, in transversal direction, the level on the guides of the bed under the tailstock, and check the air bubble Repeat these operations frequently and, if necessary, bring little corrections by screwing and/or unscrewing the adjustable feet under the bed. 8.3.3 Levelling the guides of the lathe Put the level on the sides of the carriage, and move it slowly along its whole stroke, checking that the air bubble doesn’t undergo any variation. If the air bubble moves, act on the adjustable feet until reaching a uniform level along the whole carriage stroke. Check these measurements periodically (at least every six months). Levelling the machine perfectly is one of the first and essential operations to be carried out before using the machine. Page 27 of 73 MACHINES & ACCESSORIES 8.4 Operations before starting the machine up 8.4.1 Oiling and greasing Before starting the machine up, you must lubricate it as described in paragraph 11.1, “Lubrication”. 8.4.2 Connection to the electric mains Connect the power supply cable to the terminal box located in the electric cabinet. Connect the three phases to the connectors which are present on the body of the terminal box and the earthing lead to the connector at the left of the terminal box. m o Connection Check for perfect connection of the power supply cable. The system (electric mains) to which the machine is being connected must be fitted with a circuit breaker protecting against indirect contacts. 8.4.3 c .i No-load functioning test Rotate manually the handwheels of the carriage, of the tool-holder slides and of the tailstock sleeve, checking that they move freely and without friction. Start the machine, by turning the master switch to position I, as well as the lever (the one for start and for spindle rotation reversal); make sure the electric motor and the spindle are working correctly. Try the functioning of the electric motor rotation reversal lever. Try the functioning of the pedal brake: when activated, the spindle must slow down and eventually stop. Also try the functioning of the emergency pushbutton: the whole machine must stop. Have the machine operate for a few minutes, checking the set of gears for spindle speed change, by commencing with the lower machine speeds. v r e f Projection of objects During the no-load test, no operator and no other person must be in the radius of action of the machine. Page 28 of 73 MACHINES & ACCESSORIES 9 DESCRIPTION OF CONTROLS 9.1 Controls 9.1.1 Master switch The master switch, with safety padlock, is located on the left hand side of the electric cabinet, and is useful for preventing an unauthorized use of the machine. For energizing the machine, you should:  insert the key in the padlock (on the left of the switch);  turn the key clockwise and, at the same time, turn the master switch clockwise to “I”. See that the white pilot lamp on the electric cabinet is lit, thus indicating that power supply is on. c .i m o Figure 17 – Master Switch. 9.1.2 Pushbuttons, selector switches and pilot lamps on the switchboard v r 1 (1) (2) (3) (4) e f 2 3 4 5 Figure 18 – Electric controls. GREEN PILOT LAMP: It indicates the presence of current. BLACK SELECTOR SWITCH: Coolant pump off/on. BLACK SELECTOR SWITCH: Magnetic brake off/on. BLACK PUSHBUTTON: Machine jog (running only while the pushbutton is being pressed). (5) RED MUSHROOM-HEAD PUSHBUTTON: Emergency stop of the machine. Page 29 of 73 MACHINES & ACCESSORIES The motor rotation speed selector switch is located at the front part of the machine, under the selector switches of the lathe operating modes. By turning the selector switch clockwise to position I, the motor will run at 1450 rpm. By turning the selector switch anticlockwise to position II, the motor will run at 2850 rpm. I: 1450 II: 2850 m o Figure 19 – Motor speed selector switch. Spindle speed adjustment c .i When the motor speed selector switch is turned from position I to II (or vice versa), spindle rotation stops. For restarting the machine, it is necessary to move the start/reversal lever to neutral, and then upward or downward (depending on the desired rotation direction). The spindle doesn’t restart automatically. 9.1.3 Emergency pushbutton v r On the electric cabinet there is an emergency stop pushbutton: For stopping the machine in case of an emergency, press the red mushroom-head pushbutton. As soon as pressed, it interrupts the motion of the electric motor and of the other rotating parts of the machine. Before trying to restart, make sure to raise this pushbutton – by twisting it clockwise – in order to restore power supply to the machine. e f Check the emergency pushbutton Before commencing any type of work on the machine, make sure the emergency pushbutton is functioning. In case of an emergency In case of an emergency, press the red mushroom-head pushbutton for locking the machine. Danger of abrasion and/or of cutting   After having pressed the stop or the emergency pushbutton, the spindle continues rotating by inertia. Don’t approach any part of your body to the moving spindle! Page 30 of 73 MACHINES & ACCESSORIES 9.2 Control levers and handwheels 9.2.1 Spindle speed adjustment knobs The panel for adjusting the spindle rotation speed is located on the left part of the machine, between spindle and gearbox. It is equipped with two little levers, marked with letters, for selecting the desired rotation speed as a function of the type of machining and of the material to be processed. m o c .i Figure 20 – Speed adjustment knobs. For selecting the desired rotation speed, turn the knobs to the corresponding positions, according to the indications given in this manual or on the rotation speed label affixed to the machine. v r Spindle speed adjustment Before changing spindle speed, always stop the electric motor of the machine. 9.2.2 e f Knobs for adjusting the speed of automatic feeds F G I L H Figure 21 – Knobs for adjusting the feeds. The panel for adjusting the speed of automatic feeds (see Figure 21) is located on the left part of the machine, under the spindle speed adjustment panel. Page 31 of 73 MACHINES & ACCESSORIES The various speeds are selected through 5 knob-type selector switches which operate the speed change gears (items F, G, H, I, L in Figure 21). There is also a sixth knob selecting the carriage feed direction (item E in Figure 21). THREADS c .i v r e f m o Figure 22 – Table of threads For making a thread:  Activate knob (E);  Turn the 5 knobs according to the indications shown in the table, in order to obtain the desired pitch. Note: When going to make other sorts of machining, turn selector switch G to position N (see Figure 23). Figure 23 – Knob in detail. Page 32 of 73 MACHINES & ACCESSORIES 9.2.3 Split-nut adjustment knob / lever The knob and the lever which adjust the split-nut – for transfer of motion from the lead screw to the tool-holder carriage – are located at the sides of the tool-holder carriage itself. Turning the knob or the lever by 90° will “close” the split-nut to the lead screw, thus accomplishing a rigid coupling between the two and permitting the transmission of motion from the lead screw to the tool-holder carriage (and to the tool) for the automatic feed needed for the threading operations. 9.2.4 m o Thread comparator Figure 24 – Lever in detail. The thread comparator is an instrument used for threading the piece (a bar). For threading, it is necessary to follow the table of threads appearing on the body of the lathe. Once having chosen the desired thread, you should displace the comparator by loosening the screw located at its left hand side (see the figure), and then match to the splitnut one of the three gears present on the comparator (according the thread you want to execute). At this point, threading can be executed correctly by inserting the lever of the splitnut when the number which indicates the thread to be executed matches perfectly with the reference point of the comparator. e f v r c .i Figure 25 – Threading Comparator. Page 33 of 73 MACHINES & ACCESSORIES 9.2.5 Levers and handwheels of tool-holder carriage and slides On the tool-holder carriage there are seven manual controls (levers and handwheels) which which allow adjusting it finely and setting its feed (see Figure 26). 2 m o 4 c .i 3 7 v r 1 5 6 Figure 26 – Carriage levers and handwheels. (1) Knob and lever of the split-nut: See the paragraph 9.2.3. (2) Tool locking lever: it permits locking the cutting tool at the tool-holder base (turret). (3) Handwheel for transversal displacement of the tool-holder slide: the handwheel moves the tool-holder slide finely in transversal direction, forward and backward. For displacing the slide forward (toward the piece to be machined), rotate the handwheel clockwise; vice versa, for displacing the slide backward (toward the operator), rotate the handwheel anticlockwise. (4) Handwheel for longitudinal displacement of the tool-holder slide: this handwheel moves the tool-holder slide finely in longitudinal direction, leftward and rightward. For displacing the slide leftward (toward the spindle), rotate the handwheel clockwise; vice versa, for displacing the slide rightward (toward the tailstock), rotate the handwheel anticlockwise. (5) Lever for selecting the transversal or longitudinal feeds: this lever selects the desired type of automatic feed. For activating the transversal feed, forward and backward, turn the lever downward; for activating the longitudinal feed, leftward and rightward, turn the lever upward. e f Page 34 of 73 MACHINES & ACCESSORIES (6) Lever for starting the electric motor and selecting its rotation direction: this lever selects the start and the rotation direction of the electric motor and of the other rotating parts (spindle). Turn the lever downward for the spindle to rotate clockwise; or upward for it to rotate anticlockwise. The central position, “0”, puts the spindle in neutral. m o Figure 27 – Lever in detail. (7) Handwheel for longitudinal displacement of the carriage: this handwheel executes a fast longitudinal displacement, leftward and rightward, of the tool-holder carriage. For displacing the carriage rightward (toward the tailstock), turn the handwheel clockwise; for displacing the carriage leftward (toward the spindle), turn the handwheel anticlockwise. 9.2.6 c .i Tailstock lever and handwheel On the tailstock there are manual controls (levers, handwheels and screws) for fine adjustment and for feed (see Figure 28). v r 1 e f 2 3 Figure 28 – Lever and handwheel of the tailstock. (1) Sleeve locking lever: it permits locking the tailstock sleeve (this lever is located at the non-visible side of Figure 28). (2) Handwheel for longitudinal displacement of the sleeve: this handwheel permits longitudinal displacement, leftward and rightward, of the tailstock sleeve. For moving the sleeve leftward (toward the spindle), rotate the handwheel clockwise; for moving the sleeve rightward, rotate the handwheel anticlockwise. (3) Screw for transversal adjustment of the tailstock: the screw permits adjusting the tailstock for centring it transversally. For displacing the tailstock forward (away from the operator), rotate the screw clockwise; for displacing the tailstock backward (approaching the operator), rotate the screw anticlockwise. Page 35 of 73 MACHINES & ACCESSORIES 9.3 Pedal of the mechanical brake acting on the spindle The machine is equipped with a mechanical brake which is actuated by a pedal (see Figure 29). In case of need, pressing the pedal will slow down or stop completely the spindle rotation (depending on how long the pedal is pressed). By pressing the pedal with one’s foot, the spindle is braked immediately; by releasing one’s foot from the pedal, the braking action ceases. m o c .i Figure 29 – Pedal in detail. 9.4 Digital display Precision lathe T070-400V3A is equipped with a digital display capable of monitoring the X, Y and Z dimensions with an accuracy of 0.001 mm. It allows also storing different machining depths as a function of the X coordinate at which the tool is located. v r e f 2 3 1 Figure 30 – Digital display. On the front, there are the programming keys. On the back, there are: (1) off/on switch (0/1); (2) three data cables (from top to bottom: Axis X – Axis Y – Axis Z), coming from the sensors placed on the tool-holder carriage; (3) power supply cable. Upon delivery, the display must be installed on the left hand side of the lathe, by means of the special support supplied as outfit. The plug of the power supply cable must be inserted in a socket of 230V / 50 Hz provided with earthing. Page 36 of 73 MACHINES & ACCESSORIES Connecting the data cables Pay attention to correct connection of the data cables. If reversed, the digital display will give wrong readouts. The display can be rotated and inclined for a proper view of data at any time. It can be rotated simply by moving it with a hand. For adjusting its inclination: loosen the bolt located immediately under the power supply cable, incline the panel and finally tighten the bolt again. m o Figure 31 – Panel Adjustment. 9.4.1 c .i Using the display As soon as the panel is switched on, the management system executes a self-diagnosis routine. e f v r Figure 32 – Display.

Page 46 of 73 0 8 0 0 X MACHINES & ACCESSORIES 9 – COMPENSATION OF THE LINEAR ERROR The function of compensation of the linear error is used for correcting the error of the lead screw transmission system. The correction factor is expressed as S  L  L ' L / 1000 mm / m Where: L = useful length of the Z axis, in mm; L’ = value shown on the panel, in mm; S = correction factor in mm/m. m o The correction factor can be positive if the value displayed is smaller than the actual length; negative if the value displayed is greater than the actual length. The compensation interval is of ± 1.500 mm/m. c .i Example: if the useful length of axis Y is of 1000 mm and the panel, upon carriage stroke end, shows 999.98 mm, then S=(1000-999.98)/(1000/1000)=0.02 mm/m. Thus, for entering the compensation value, there is to: Select axis Y by pressing button correction factor is displayed. - Press button in order to select axis Y. By pressing button S correction factor is displayed. s - e f v r 0. 0 5 0 , the previously set S M/ , the previously set Y Enter the 0.02 calculated value by pressing keys 0 . 0 2 in sequence. s - . By pressing button M/ - Press button 0. 0 ENT 2 0 Y to confirm the datum. Compensation of the linear error can be executed when either the absolute or the relative coordinates are being displayed. 10 – INTERRUPTION OF THE ELECTRIC POWER SUPPLY If the electric power supply is interrupted, or if it is necessary to switch the lathe off while it is machining, the panel will still be capable of storing automatically the present tool coordinates, the presently set compensation factor, and the display mode. When the machine will be switched on again, the display will show – soon after the initial selfdiagnostics phase – exactly the data that existed immediately prior to interruption. If the tool and/or the piece have not been displaced, it is possible to resume machining without any problems. Page 47 of 73 MACHINES & ACCESSORIES 10 OPERATION Expected use and materials Precision parallel lathe T070-400V3A is designed for machining metallic materials through cold removal of shaving. Any different use, and deviation from the technical parameters established by the Manufacturer, may set a condition of danger to operators; therefore, the Manufacturer will not assume any responsibility for the possibly resulting damages. m o Risk of abrasion and other accident   Before using the machine, make certain it is secured correctly, so that its displacement or loss of stability is prevented. Wear adequate personal protection equipment (PPE) such as: gloves, goggles, overalls or apron and safety shoes. c .i Usage environment    The Lathe can operate in closed work environments (production departments, halls, etc.), namely sheltered from weather conditions, and where there are no dangers of fire or explosion. Usage temperature range is of –10°C to +50°C. The environment must also be sufficiently lit in order to assure operation under maximum safety (at least 50 lux). e f v r Operating near the spindle Before commencing to operate in proximity of the spindle, ALWAYS be sure the machine is steady (not vibrating or displacing itself). Page 48 of 73 MACHINES & ACCESSORIES It is recommended not to extend continuous use of the machine beyond 10 minutes, in order to avoid overheating its motor and tool (which might get damaged). 1. Raise the mobile shield of the spindle. 2. Apply to the spindle the piece to be machined, and secure it by tightening the jaws by means of their wrench. Insert the wrench in one of the square-section slots of the spindle and, for approaching the jaws among them, turn it clockwise (see Figure 37). c .i Figure 37 – Spindle wrench. v r Locking the piece m o Lock the piece stably and safely to the self-centring spindle by tightening the jaws with the necessary force. 3. If necessary, lock the opposite end of the piece by means of the tailstock. For doing so, adjust the position of the tailstock and of its sleeve by using their fixing handwheel and lever (see Figure 28). 4. If necessary, check the eccentricity of the piece, by using a comparator and by rotating the piece slowly (by hand) after having fixed it between the centers (see Figure 38). e f Figure 38 – Checking the eccentricity of the piece. Page 49 of 73 MACHINES & ACCESSORIES 5. Fit the tool in the turret of the tool-holder carriage, and secure it by means of the locking lever (item l in Figure 26). 6. Adjust the position of tool-holder carriage and slides, by using their levers and handwheels (see Figure 26). 7. Lower the mobile shield of the spindle. Using the machine m o Before starting the machine, ALWAYS close the mobile shield of the spindle. This will provide an adequate protection to the operator regarding the mechanical risks from the spindle as “dangerous zone”. 8. On the knobs of the control panel of the machine (see Figure 20), set a proper rotation speed to the spindle. 9. Turn the master switch to position “I” (see Figure 17), and see that the white pilot lamp of voltage present (item C in Figure 18) has got lit. 10. Displace the electric motor start lever in order to initiate spindle rotation, at the same time selecting also the rotation direction. 11. Execute machining of the piece, by approaching – via the handwheels (items M and N in Figure 26) that adjust finely the movement of the tool-holder slides – the tool to the piece itself (already rotating). If necessary, approach to the zone involved in machining, the nozzle of coolant liquid and activate its pump. 12. Once machining is completed, move the tool away from the piece; then, by means of the start lever, interrupt spindle rotation. v r c .i e f Abrasion and/or cutting dangers   After having turned the start lever to “neutral” or after having pressed the emergency pushbutton, the spindle continues rotating by inertia. In case you want an immediate stop, you should press the brake pedal under the bed of the machine until the spindle stops. Don’t approach any parts of your body to the spindle while it is moving! 13. After having awaited the stop of the spindle rotation, raise the mobile guard and dismount the piece from the spindle (open the jaws by means of their wrench). To do so, insert the wrench in one of the square-section slots of the spindle, and turn it anticlockwise. Page 50 of 73 MACHINES & ACCESSORIES 10.1Automatic feeds of the tool-holder carriage LONGITUDINAL FEED The automatic longitudinal feed of the carriage is exerted by the spindle, which transmits its motion to the slotted bar (see Figure 39). Longitudinal feed is due to the lower slide that pulls the carriage in longitudinal Lathe axis direction. A worm screw (B), keyed onto the slotted bar (A), slides along the bar itself together with the carriage. The worm screw rotates a gearwheel (D) and the other gears present, among which is pinion (M) that meshes with rack (N); this one, while moving, pulls the carriage during rotation of the pinion. TRANSVERSAL FEED c .i v r Transversal feed is exerted by the transversal slide which pulls the upper slide and the tool in cross direction, i.e. perpendicular to the Lathe (see Figure 40). By turning lever (E) to position 3, idle wheel (O) meshes with pinion (G) which is integral to screw (H). The screw is coupled to scroll (I) which is integral to the transversal slide. Thus, screw rotation moves the transversal slide. e f m o Figure 39 – Longitudinal feed. Figure 40 – Transversal feed. Page 51 of 73 MACHINES & ACCESSORIES LONGITUDINAL FEED FOR THREADING OPERATIONS Automatic longitudinal feed of the carriage is exerted by the spindle, which transmits its motion to the lead screw, in turn connected to the spindle itself by gears that permit varying its rotation speed (see Figure 41). The lead screw, with its rotating motion, exerts a thrust to the fixed scroll of the carriage, thus determining its automatic feed in longitudinal direction. m o c .i Figure 41 – Longitudinal feed with the lead screw. The speed change of feeds of Precision parallel lathe LC340/1000 is of mixed type: mechanical with knobs for selecting the speeds (see paragraph 9.2.2) and with replaceable gears. For substituting the gears, proceed as described below: v r Squeezing danger e f Before replacing the gears, extinguish the machine by turning the master switch to position “0”. 1. Open the shield of the feed speed change gearbox, located on the left part of the machine; 2. Unscrew the fixing nuts of the gears, and dismount these (see Figure 42); 3. Mount the gears relating to the desired feeds while checking their perfect coupling, then tighten the fixing nuts; 4. Close the gearbox shield. Figure 42 – Gears. Page 52 of 73 MACHINES & ACCESSORIES 11 MAINTENANCE Electric shock Before every check or maintenance, switch the machine off and ALWAYS detach the power supply cable plug. This will prevent the risk of electric shocks. m o Clean your machine regularly and take care of it. This will assure its perfect efficiency and long life. At the end of every machining, by using a compressor you should blow away all shavings, filings and dust that have accumulated on the machine and its bed. Works with the compressed air c .i When using compressed air, ALWAYS wear goggles. At the same time, check the status of the Lathe and of its warning and operator labels; if they aren’t anymore legible, request others. v r Don’t use the Lathe if you encounter defects in it !! Daily checks 1 Check that all moving parts are well lubricated. 2 Clean the surfaces of spindle, turret and machine body. 3 Make sure there are no objects or tools near moving parts. 4 Check the functioning of handwheels. 5 Check the wear of sliding guides. e f Page 53 of 73 MACHINES & ACCESSORIES 11.1 Lubrication It a good rule to clean the machine, and in particular its guides, by removing all shavings produced by the work. With a cloth or a brush, smear a light layer of oil on the guides and on the spindle, in order to prevent any phenomena of corrosion. Remember, the morning after, to remove the oil before starting the machine. Perfect efficiency of the lathe is guaranteed over the time by a perfect lubrication of its moving parts. m o Lubrication Don’t use the machine, if you encounter oil leaks or if the oil levels are not perfect. Lubrication   c .i Utilize only the lubricants indicated in the table here below. DON’T use types or grades unlike those indicated, DON’T exceed in quantity and DON’T let their level go under the proper one shown by the indicators. The main gears of the lathe are shake lubricated; the lubricant oil level is indicated by the oil windows (see figure 32). The other parts to be lubricated manually are specified in the following table, together with the type of lubricant and the lubrication interval. The lead screw must be lubricated with lithium grease through the special greaser. The lubricant oil must be substituted entirely, when the lathe is new, after its first week of work. For correct lubrication of the Lathe, proceed as follows (see Figure 43): v r e f Page 54 of 73 MACHINES & ACCESSORIES m o v r c .i Figure 43 – Machine lubrication points. Type of lubricant Frequency Substitution frequency Oil Monthly / 1 Oil Monthly / 2 Oil Monthly / 2 Oil Monthly / Longitudinal slide 3 Oil Monthly / Longitudinal feed handwheel 1 Oil Monthly / Transversal feed handwheel 1 Oil Monthly / Tool-holder 1 Oil n°20 Level indicator 6 months Spindle gears 1 Oil n°20 Level indicator 6 months Carriage guides 4 Oil n°20 Monthly / Threading gears 1 Oil n°20 Level indicator 6 months Machine Part Points to be lubricated e f Lead screw bearings and feed shaft Transversal feed scroll Tailstock sleeve and handwheel Transversal slide 2 Page 55 of 73 MACHINES & ACCESSORIES Recommended Oil Types Mobil Vectra n° 2 Shell – Tonna – T68/TX68 Chevron – Vistac – 68X Esso – Febis – K68 Lubrication m o DON’T disperse used oil in the environment. Apply to authorized consortiums for collection and clearance of used up oils. 11.2 Periodical checks Every 6 months of life of the machine, execute an in-depth check of functioning and of wear, and level the bed accurately. The transmission gears do not need any maintenance, except for substituting the oil. c .i 11.3 Adjustments of the machine 11.3.1 Adjusting the tension of the motor belts Make sure the tension of motor belts is the appropriate one. To do so, just press strongly on the individual belts (approximately at their central position): they must move by a maximum of 5 mm. If the belts are lose or too taut, undo the bolt of the belt adjustment system until achieving the correct tension. v r e f Proper tension of the belts reduces their wear and increases machine effectiveness. 11.3.2 Alignment of the tailstock When the tailstock is misaligned, it is necessary to correct its position by turning the adjustment screw until the reference marks on the side label are aligned. Figure 44 – Adjustment screw. Page 56 of 73 MACHINES & ACCESSORIES 11.3.3 Spindle alignment When the spindle rotates misaligned, or if particularly heavy machining is to be executed, its bearings are to be adjusted. The bearing that supports the spindle is conical. For adjusting it, proceed as follows (see Figure 45): 1. Unscrew the locking nut of the bearing; 2. Tighten the bearing adjustment nut; 3. Test the spindle by rotating it, and – by means of a comparator (see point 4, chapter 10) – make sure it rotates perfectly; 4. Tighten again the locking nut of the bearing. 11.3.4 m o c .i Adjusting the backlash of gears It is very important that there isn’t abnormal play between gears: backlash is a cause of break of gears and of quick wear of gear teeth. v r Figure 45 – Spindle alignment. II For reducing and/or adjusting the backlashes, move gear II and tighten nuts III and IV strongly (see Figure 46). e f IV III Figure 46 – Backlash of gears.
