The KM Micro/KM Mini coupling offers a very rigid joint with a high degree of repeatability while maintaining a very compact envelope. This permits a high degree of versatility without sacrificing cutting performance. Wh KENNAMETAL M63 Technical Information Kennametal KM Micro /KM A Technical Information Mini Manual Clamping System Locking Sequence Installation The clamping sequence starts with the insertion of the cutting unit into the female taper of the clamping unit. The cutting unit first makes contact at a stand-off from the gage face of approximately .010" (0,25mm). The torque screw is then activated by a preset torque wrench at a right angle to the centerline of the cutting tool, located behind the gage face of the clamping unit. A small amount of elastic deformation takes place at the front of the female taper as the locking force is applied. As the torque screw is further tightened to the preset torque of 25-30 ft. lbs. (34-40 Nm), (4-1/4 turns), the cutting unit advances until the gage face makes contact with the face of the clamping unit. The final amount of torque applied allows the tail of the cutting unit to spread to clamp securely between the clamping mechanism and the clamping unit inside diameter. Once the proper operational torque is achieved, continuing to rotate the torque screw may damage the clamping components. When initially clamping the KM Micro/KM Mini shank in a machine tool slot, it is recommended to have a cutting unit in the shank. Lubrication Using the appropriate wrench, back out the torque screw against the positive stop and generously apply grease to the threads and conical surface of the component hardware. Also, apply grease to the female taper surface. This should be done periodically. Recommended grease: GLEITMO 805. lubricant order number size GLEITMO 805 grease 1567575 500g cartridge GLEITMO 805 grease 1567577 1000g tin CAUTION DO NOT USE silicone cleaner or WD-40 -type lubricants.
