Automatic Clamping System

Operating Instructions

The KM automatic clamping system uses a disc spring package to supply force to

the lock rod — driving the locking balls and providing clamping force to the cutting

unit. The mechanical advantage of the clamping mechanism is designed specifically

for a given spring force to supply proper clamping force. Once the cutting unit

is clamped in the KM automatic clamping unit, it is securely held in place until

released by applying force to the end of the spring end cap. In most cases, this

is accomplished using a hydraulic cylinder. KM automatic clamping units contain

sealed coolant ports as well as a system for distributing air through the unit.

Air serves two functions: (1) air is used to clean the taper and face area during

tool change; (2) it is also used to detect improper tool change. Air is routed to

the intersection of the taper and the face. If the faces of the cutting unit and the

clamping unit do not totally seal after a tool change, air will continue to escape

and can be used to detect a tool change fault. KM automatic clamping units are

available in several configurations for application on a wide variety of machines.
