Technical Information Technical Information KM Rapid Clamping System Kennametal KM Rapid Clamping Units Operating Instructions The KM Rapid clamping system is a compact quick-change tooling system that does not require a torque wrench to achieve proper clamping force. The KM Rapid clamping unit spring pack supplies the correct clamping force while the cam permits quick and easy locking/unlocking of the KM cutting unit. KM Rapid Locking Sequence At the “unlock” position, which is marked on the housing, the cutting unit can be removed or fitted in the clamping unit. By moving the cam clockwise, the locking balls are pushed outwards and the face stand-off gets closed. Moving the cam further pushes the locking balls further outward and generates clamping force at the locating face. The handling force moves past the maximum position, then slightly back, to reach the “lock” position. KM Rapid Unlocking Sequence To unlock the cutting unit, turn the cam counterclockwise. In this position, the locking balls are free of the cutting unit, but the taper interference is still holding the KM cutting unit in the clamping unit. By turning the cam further to overcome the interference, the cutting unit will be released and can be removed. In any case, do not try to push too hard against the unlocking point because it will result in damage to the locating pin and the cam. The entire locking and unlocking sequence takes a few seconds. KM Rapid Plus Clamping Units Operating Instructions The KM Rapid Plus clamping system is a compact cartridge quick-change tooling system that does not require a torque wrench to achieve proper clamping force. The KM Rapid Plus clamping unit spring pack supplies the correct clamping force while the cam permits quick and easy locking/unlocking of the KM cutting unit. KM Rapid Plus Locking Sequence At the “unlock” position, the cutting head can be removed or fitted in the clamping unit. By moving the eccentric shaft clockwise, the axial lockrod is moving, the clamping balls are pushed outward, and the face stand-off is closed. Moving the eccentric shaft further pushes the locking ball over the axial lockrod further outward and generates clamping force at the locating face. The handling force moves past the maximum position, then slightly back, to reach the “lock” position. Do not move the cam further at this position. KM Rapid Plus Unlocking Sequence To unlock the cutting unit, turn the eccentric shaft counterclockwise. In this position, the locking balls are free of the clamping unit, but the taper interfence is still holding the cutting unit in the clamping unit. By turning the eccentric shaft further to overcome the interference, the cutting head will be released and can be removed. The entire locking and unlocking sequence takes a few seconds. M34 Kennametal
