Basic safety instructions
2.4 Notes on safe operation • The machine spindle may only be started up when clamping pressure has built up in the cylinder and clamping has followed in the permitted work area. • Unclamping may only be possible when the machine spindle has come to a standstill. • If the clamping energy fails, the workpiece must remain firmly clamped until the spindle is shut down and the workpiece is secured. • The technical safety requirements in the respective operating instructions must be observed exactly. Functional test After installation of the chuck, its function must be checked prior to start-up. There must be no leaks in the piping system here. Two important points are: • Clamping Force! The clamping force of the chuck must be achieved at max. operating force/pressure. • Stroke control! The stroke of the clamping piston must allow a safety zone at the front and rear end position. The machine spindle may only be started when the clamping piston has passed through the safety zone. Only limit switches that meet the requirements for safety limit switches specified in DIN EN 60204-1 may be used to monitor the clamping path. If the chuck jaws are changed, adjust the stroke control to the new situation. Maintenance instructions The chuck's reliability and safety can only be guaranteed if the operator complies with the manufacturer's maintenance instructions. • For lubrication, we recommend our tried special grease, LINO MAX. Unsuitable lubricants can have a negative impact on the chuck (clamping force, coefficient of friction, wear characteristics). (For product information about LINO MAX, see the "Accessories" section of the current SCHUNK lathe chuck catalog or contact SCHUNK). • Use a suitable high-pressure grease gun to ensure that you reach all the greasing areas.
10
01.01|ROTA NCK-S plus |en
Basic safety instructions • To ensure correct distribution of the grease, move the clamping piston to its end positions several times, lubricate again, and then check the clamping force. • We recommend checking the clamping force using a clamping force tester before starting a new production run and between maintenance intervals. “Only regular checks can guarantee optimal safety”. • The clamping force should always be measured in the state of the chuck as used for the current clamping situation. If top jaws with clamping steps are used, measuring must be performed in the same step as for the respective clamping task. • Move the clamping piston through to its end position several times after 500 clamping strokes, at the latest. (This moves the lubricant back to the surfaces of the force transmission. The clamping force is thus retained for a longer period of time.) Safety notes for servicing Follow all the applicable legal norms for health and safety during servicing. Use suitable personal protective equipment, especially protective gloves, goggles and safety boots, paying particular attention to the operating system and hazard assessment.
DANGER Possible risk of fatal injury to operating personnel due to chuck failure if the servicing instructions for the chuck are disregarded! The servicing instructions specified by the manufacturer must be complied with to ensure safe operation of the chuck. Work must be carried out by qualified specialist personnel with the relevant safety training. Use of special designed jaws When using special designed jaws the following rules must be observed: • The jaws should be designed as light and as low as possible. The clamping point must be as close as possible to the chuck face (clamping points at a greater distance lead to greater surface pressure in the jaw guidance and can significantly reduce the clamping force). • Do not use welded jaws.
01.01|ROTA NCK-S plus |en
11
Basic safety instructions • Screw the jaw mounting screws into the bore holes furthest apart. • If the clamping device is involved in a collision, it must be subjected to a crack test before using it again. Damaged parts must be replaced by original SCHUNK spare parts. • The jaw fastening screws must be replaced if they show any signs of wear or damage. Only use screws with a quality of 12.9. 2.4.1 Substantial modifications No substantial modifications may be made to the chuck. If the operator carries out a substantial modification to the chuck, the product shall no longer conform to the EC Machinery Directive 2006/42/EC.
2.5 Personnel qualification Assembly and disassembly, commissioning, operation and repair of the chuck may be performed only by qualified specialists who have been instructed with respect to safety. All persons who are assigned to operate, maintain and repair our chuck must have access to the operating manual, especially the chapter “Fundamental safety instructions”. We recommend that the operator create in-house safety operating instructions. Persons in training may be assigned to machines and technical equipment in which a chuck is mounted only if they are under the constant guidance and supervision of qualified specialists.
2.6 Organizational measures Obeying the rules Via suitable organizational measures and instructions, the operator must ensure that the relevant safety rules are obeyed by the persons asked to operate, maintain and repair the chuck. Checking the behavior of personnel The operator must at least occasionally check that the personnel are behaving in a safety conscious manner and are aware of the potential hazards.

Function and handling
8 Function and handling The item numbers specified for the corresponding individual components relate to chapter drawings.( 12, Page 28)
8.1 Function of the lathe chuck The lathe chuck is actuated hydraulically via the two swivel fittings (OPEN/CLOSED). The resulting axial tensile and pressure forces are converted to the radial jaw clamping force by the wedge hook angle in the piston and base jaws. The clamping and opening path of the chuck jaws is determined by the clamping piston. The serration of the base jaws can be used to standard jaws as well as mount customized chuck jaws for complicated workpiece shapes. The top jaws are moved or changed in the open clamping position.
8.2 Replacement or enlargement of jaws Tighten the jaw mounting screws (screw grade 12.9) to the specified torque. ( 4, Page 14)
WARNING Risk of injury due to loss of workpiece if it is clamped at the end of the base jaw stroke. • Always clamp the workpiece at half of the base jaw stroke. Chuck jaws for maximum clamping repeat accuracy must be turned or ground in the lathe chuck under clamping pressure. • When turning or grinding, ensure that the turning ring or turning pin is clamped by the top jaws and not by the base jaws. Tighten the jaw mounting screws with a torque wrench. Never tighten the screws with an extension pipe or with hammer blows.

Maintenance
9 Maintenance 9.1 Lubrication To maintain the safe function and high quality of the lathe chuck, it must be regularly lubricated at the lubrication nipples of the base jaw. Put the lathe chuck in the open position and lubricate the 3 lubrication nipples with SCHUNK LINO MAX special grease using a high pressure grease gun. For optimum grease distribution, the clamping piston must travel the entire clamping stroke several times after lubrication. Check clamping force, repeat procedure if necessary. (For product information about LINO MAX, see the "Accessories" chapter of the current SCHUNK lathe chuck catalog or contact SCHUNK).
CAUTION Allergic reactions due to grease in contact with skin! Wear gloves. Operating conditions: Depending on the operating conditions, the function and clamping force must be checked after a certain period of operation ( 9.2, Page 24). Only use a calibrated clamping force tester for measuring during the clamping force test (SCHUNK GFT 0890012). Technical condition The base jaws must move evenly when the smallest possible actuating pressure is applied (clamping cylinder). This method only provides a limited indication and is not a substitute for measuring the clamping force. If the clamping force has dropped too much or if the base jaws and piston no longer move properly, the chuck must be disassembled, cleaned, and relubricated.
01.01|ROTA NCK-S plus |en
23
Disposal
9.2 Maintenance intervals Lubrication of the grease areas: Lubrication interval Strain every 25 hours
normal / coolant utilization
every 8 hours
high / coolant utilization
after 1200 hours or Total cleaning with disassembly of the as needed chuck, depending on type and degree of contamination
9.3 Technical Condition At the smallest possible actuating pressure (clamping cylinder), the base jaws have to move evenly.This method has only limited usefulness and does not replace the clamping force testing. If clamping force has dropped too low, or if base jaws and piston cannot be moved perfectly, it is necessary to disassemble the chuck to clean it and to relubricate it. For exchange of dammaged components, only use the original SCHUNK-spare parts.
10 Disposal After decommissioning, place the chuck in a position that enables any liquids in the chuck to drain out. • Collect the escaping liquids and dispose of them properly in line with the statutory provisions. • Remove any identifiable plastic or aluminum parts installed in or on the chuck and dispose of them properly in line with the statutory provisions. • Dispose of the chuck's metal parts as scrap metal. Alternatively, you can return the chuck to SCHUNK for proper disposal.
