BERG CLAMPING SYSTEMS – HK / HKR

TOOL CLAMPING – HK / HKR
Gripper HSK-Hollow Shank Tooling
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 positioning 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 toll to be hold securely in the spindel even in unclamped position.

Comments : When clamping without a tool the draw-bolt of the clamping set is supported at the end of the total stroke hT in the depth ‘m’ inside the spindle. If no possibility for the stop is provided at this point, it has to occur at a different point.-
