The MultiChuck MMY concentric clamping system, the winner of Best Workholding Product at the International Machine Tool Industry Awards 2000, brings a host of advantages to the self-centring of round parts on vertical and horizontal machining centres, milling machines and grinders - not least rapid clamping and short set-up times.

This is courtesy of a simple top face operation that enables more chucks, and therefore workpieces, to be ''banked'' closely together - which is not the case with the traditional side face lock/unlock strategy.

Available with two or three jaws, MultiChuck MMY combines fast initial jaw travel with controlled second-stage clamping to provide a large jaw opening with high gripping force.

Jaw strokes are 4 mm, 5 mm, 8 mm and 10 mm across the four variants, and the low height (from 25 mm to 40 mm across the range) maximises the machine's Z axis (height can be increased using blocks). Quick change top jaws can be supplied to suit most materials/components.

MultiChuck MMY can be provided as standard in a range of chuck sizes - 80 mm, 100 mm, 125 mm and 150 mm - and with base dimensions of 80 mm by 80 mm, 100 mm by 100 mm, 125 mm by 125 mm and 150 mm by 150 mm. It will fit all slotted machine tables.

MultiChuck MMY is available for external and internal clamping and will satisfy both first and second operations in the same machining cycle - thereby providing continuous output of finished components.
