LOCKING - Before inserting the KM unit into the clamping unit (fig. 1), clean the contact face and taper. Turning the torque screw clockwise locks the KM cutting unit in position. To ensure proper clamping forces are exerted for maximum safe operation, tighten the unit to the specified torque using a torque wrench.

SIZE KM40 KM50
UNLOCKING - Rotate the torque screw counterclockwise (Fig. 3) until initial resistance is felt. In this position, the locking balls are free of the cutting unit, but the taper interference is still holding the KM unit in the clamping unit. At this point, the bump-off pin is in position to free the cutting unit from the interference fit.

Operating Instructions ACTUATION – Driven Tools are equipped a removable access plug for engagement into the KM Manual Clamping Unit. To change tools, simply pull the o-ring sealed plug out. Remember to reinstall the plug by pressing it in the housing prior to any machining.

Fig. 1 OPERATING POSITION - With the balls locked in position (Fig.2), and the face and self-locking taper fully engaged, the cutting unit and clamping unit are rigidly secured together.
CAUTION: Continuing to rotate the torque screw may damage the clamping components.

Continue to rotate the torque screw slowly until the cutting unit is no longer making face contact (Fig. 4) and is released from the taper. The torque screw will stop rotating and a second resistance will be felt. Do not turn the torque screw any further.
Fig. 2 CAUTION: Do not use the engagement torque screw for retaining or holding the driven tool spindle during tool changes.

CAUTION: Verify torque screw is fully retracted prior to rotation of the driven tool. KM SPINDLE-PLUG (01-06)
SAFEY, SETUP AND OPERATION INSTRUCTIONS You have purchased a quality product. The long term performance of the product will to some extent depend on the service and treatment you give the product. Failure to read and follow these instructions may invalidate the warranty. SAFETY: Safe operation depends on use in compliance with engineering information, proper installation and operation, routine maintenance and inspection under prevailing conditions. The cutting tool should be removed prior to installing or removing the driven tool from the turret. It is the responsibility of users to provide and install guards or safety devices which may be required by recognized safety standards or by the Occupational Safety and Health Act of 1970 and it subsequent provisions. TOOL ROTATION: Always verify the driven tool rotation in respect to the machine turret drive rotation prior to machining. Tool rotations vary from one supplier to another and even within a supplier’s line. LUBRICATION: Driven tools are lubricated from the factory. They require no lubricant addition or change for the life of the driven tool. If you feel the driven tool requires re-lubrication or any other service or maintenance, it should be shipped back to the factory for that service. Do not open or self-service any driven tool still under warranty, as this will void the warranty. O-RING SEALS: O-rings for the coolant entry port and post shank are provided. Be sure they are properly seated. Some tools have multiple coolant entry ports to fit multiple machines. Be sure the o-ring is in the appropriate entry port before mounting to your turret. EXTERNAL COOLANT TUBE SUBASSEMBLY: A coolant subassembly has been shipped loose. Screw the fitting clockwise into the driven tool until it is finger tight. Use a wrench to screw the fitting in an additional two revolutions. Continue to tighten the fitting until the fitting opening is aligned with the driven tool spindle. Do not loosen the fitting even if you go past the spindle center as this could cause a coolant leak. Insert the copper tube and tighten the retaining nut. Some tools have multiple coolant ports so proper placement of your coolant tube can be achieved. INTERNAL COOLANT SUPPLY: Coolant should be turned on prior to rotation. Never run driven tools with internal coolant supply without coolant. Coolant should be filtered through a 20 micron filtrations system.
ADJUSTABLE LOCATING PINS: Most driven tools are shipped with adjustable locating pins or locating bores which are set to a theoretical zero. Each lathe turret is unique and may require that the driven tool spindle axis is set to the lathe turret zero for that specific turret location the tool will occupy. Place the driven tool in the specific turret location. Loosen the socket-head cap screw. Use the two adjustable socket head screws to find the tool spindle axis zero. Once the axis zero is set, tighten and torque the adjustable socket head screws to 6 lb-ft. Then tighten and torque the holding socket head screw to 32 lb-ft. BREAK IN PERIOD: All driven tools are run at the factory prior to shipment. However, for best results and when running the driven tool for the first time or after it has not been used for a period of 40 hours or when o stored in a temperature less than 50 F, it should be run for a minimum of five minutes without a load at less than 500 RPM. This allows the grease film to be reestablished on the bearing contact zones. Then run at 70% of the machines maximum RPM for two minutes.
SERVICE: Driven tools may require service before the expiration of the warranty period. These circumstances might include the following: collision between the driven tool and a work piece or chuck; overload from use of modified or nonstandard tooling; operational periods greater than 10/60 (the tool used more than ten minutes in a sixty minute period). WARRANTY: The life of the driven tool depends on the application. Periodically, perishable components (i.e. bearing, seals) need to be replaced. Under normal circumstances and conditions these components should last a minimum of 2000 hours of operation or one year. For special applications, a bearing life calculation can be estimated.
STORAGE: Driven tools should be stored in a clean and dry location with the spindle bearings in a horizontal position that will allow bearing grease to uniformly settle in the contact zones around the bearing races. Cutting tools should not be left mounted in or on driven tools when not in use. Corrosion between the tool and taper faces will compromise the accuracy and performance. CLEANING: Do not use air pressure or solvent in or around the seal area. Use a clean wipe made of lint free material. Protect and clean mounting surfaces of the driven tool. PERFORMANCE: We will make suggestions to achieve the best performance results (i.e. cutting parameters, duty cycle, and torque). Our ratings are based on suggested guidelines, engineering calculations and our own actual experience. They should be used only as an initial selection guide. We cannot guarantee that these ratings will prove satisfactory for all applications. Complete suitability can be determined only through prototyping and field testing. Some cutting tool parameters have been known to cause premature failures. In these instances, consult with the factory for a bearing life calculation for your specific application. Never operate the driven tool beyond the maximum torque or output RPM rating stated. If the driven tool is used over the torque limit, it may result in short performance and or cause damage or failure to the bearings.
