KM Micro/KM Mini Clamping Operating Instructions (KM12-KM25) Locking Before inserting the KM Micro and KM Mini unit into the clamping mechanism (Figure 1), clean the contact face and taper. KM Micro and KM Mini manual clamping units require a torque wrench for proper operation. Turning the torque screw clockwise locks the cutting unit in position. For maximum safety, tighten the torque screw to the specified torque. Using a torque wrench ensures that the proper clamping forces are exerted. CAUTION Over tightening can cause damage to the clamping mechanism. Operating Position With the torque screw and nut to the proper torque, coincidental cones locked in position, and the face and self-locking taper fully engaged, the cutting unit and clamping unit are rigidly secured together (Figure 2). Unlocking Rotate the torque screw counterclockwise until initial resistance is felt. In this position, the locking cones 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 angle is in position to free the cutting unit from the interference fit. Continue to rotate the torque screw slowly until the cutting unit is no longer making face contact (Figure 3) and is released from the taper. The torque screw will stop rotating and more resistance will be felt. Do not turn the torque screw any further. CAUTION Continuing to rotate the torque screw may damage the clamping components.
