Internal gripping segmented mandrels from 8 mm diameter

The HAINBUCH MANDO T212 utilises segmented internal clamping bushes to clamp diameters, as small as, 8 mm.

The T212 mandrel has no projecting draw bolt, so there is no wasted clamping length, and a vulcanised, hardened clamping bush eliminates traditionnal fragile spring steel. The standard XXS system covers a clamping range of 8 to 100 mm. Endstops can be fitted in front or behind the mandrel and the pull back clamping operation gives a very positive location with an accurate, rigid grip. It is also very quick to change and can be used for open or blind bores. The T212 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. Special application versions can be designed to order and have included internal clamping solutions, to 400 mm diameter, and profiled bore gripping.
