Print Data Sheet

Show/HideDescription

Application

Clamping sets of the type HKR are designed for clamping hollow shank tools according to DIN 69893.

Design Features

HKR clamping sets have six collets held by an annular spring which allows a rocking movement for inserting and removing the hollow shank tools. During clamping the taper of the centrally positioned draw-bolt increases the actuation force, thereby generating a much higher clamping force at the collets. The special tribolic coating guarantees the highest possible constant clamping force. The clamping set is maintenance free.

A locking bolt permits infinitely variable position and fixation of the clamping set in the Z axis. No special tools are required for assembly and disassembly.

The spindle has an easy to produce interior contour. The HKR gripper has a built-in snap-hold feature allowing a tool to be held securely in the spindle even in an unclamped position.
