Technical Information Technical Information KM Manual Clamping System Kennametal KM Manual Clamping Units KM Manual clamping units require a torque wrench to operate. Using the proper torque wrench value is critical. Tighter is not better because over tightening can cause damage. The specific operating torque of the KM manual clamping units is listed on each unit. The KM connection must be kept clean and free from nicks and burrs. KM plugs are available to ensure cleanliness when a cutting unit is not engaged in the clamping unit. When a KM head is unlocked, the head will bump-off. KM’s 10:1 taper is selflocking, and therefore, requires a mechanical release. This is accomplished within the design of the KM System and does not require operator intervention. After the head has been released, you will need to turn the torque screw another 3/4 1-1/2 turns. This rotation will feel free of resistance. When the free turning motion stops, the head can be pulled from the clamping unit. Do not turn the torque screw further, as damage can occur to the lockrod and/or bump-off pin. KM Manual Clamping System Single-Pin Design KM Manual Clamping Components Functional Definitions 1. Clamping Unit Body Primary component of the clamping unit assembly, less additional hardware. 2. Canister Pin Secures ball canister to clamping unit body. 3. Pin Canister Main component of KM clamping mechanism holds and locates the locking balls and bump-off pin. 4. Torque Screw Rotation moves the lockrod: a. Clockwise rotation advances lockrod, securing cutting unit (not shown). b. Counterclockwise rotation retracts lockrod, releasing cutting unit (not shown). 5. Lockrod Dual function: a. Acts as a wedge when advanced between locking balls, causing them to move outward in the ball canister and pushing the locking balls into the ball tracks of the cutting unit (not shown). b. Acts as a wedge when retracted using a raised, tapered key to force the bump-off pin against the cutting unit (not shown). 6. Locking Balls (2) Precision, chrome alloy-steel hardened balls used to transmit pull-back force to the cutting unit. 7. Bump-Off Pin Dual function: a. Releases cutting unit from the clamping mechanism. b. Prevents lockrod from rotating. 8. Bump-Off Pin Retention Screws (2) Secures bump-off pin in ball canister. M22 Kennametal
