Take stock

Hainbuch Mando T212 segmented internal clamping bushes are used extensively for customer specific workholding solutions, but now the company has announced that the proven mandrel principle is not only available from stock as part of Hainbuch's standard product line, but also in XXS format with a minimum diameter of just 8mm.

The T212 mandrel has no projecting draw bolt, so there is no wasted clamping length and no fragile spring steel slotted mandrel due predominantly to the vulcanised, hardened clamping bush. The standard system covers a clamping range of 8mm to 100mm.

Endstops can be fitted in front or behind the mandrel and through the pull back clamping operation, a positive location and accurate, rigid grip can be achieved. It is also quick to change and can be used for open or blind bores.
The mandrel can be fitted to any type of turning or static machine – either as a standalone mandrel or a quick fit accessory on the front of the Hainbuch collet system.

Versions are available for special applications which can be designed to order and have included internal clamping solutions to 400mm diameter and profiled bore gripping.
