Through-hole feature extends chuck capability

Edited by the Manufacturingtalk editorial team Feb 18, 2004

By simply adding a through-hole to an award winning chuck having a concentric clamping system, the result is unobstructed on-centre through component drilling, reaming and tapping.

By simply adding a through-hole to the award-winning MultiChuck MMY concentric clamping system, the new MultiChuck MMYB system being shown at MACH 2004 by Leader Chuck Systems is designed for unobstructed on-centre through-component drilling, reaming and tapping operations.

Designed for both the internal and external gripping of workpieces on vertical and horizontal machining centres and milling machines, MultiChuck MMYB brings a host of advantages to the self-centring of round parts - not least rapid clamping and short set-up times.

Derived from the MultiChuck MMY, which was the Best Workholding Product at the International Machine Tool Industry Awards, MultiChuck MMYB's simple top face operation 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 MMYB combines fast jaw travel with high gripping force.

Jaw strokes are 3mm, 3mm, 4mm and 5mm across the four variants - chuck types 80, 100, 125 and 150 that have base dimensions of 80mm by 80mm, 100mm by 100mm, 125mm by 125mm and 150mm by 150mm, respectively.

Through holes of 12mm, 20mm, 25mm and 35mm diameter are available across the range, to suit users' requirements.

The low height of the chucks, from 25mm to 40mm 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 MMYB chucks will fit all slotted machine tables, and will satisfy both first and second operations in the same machining cycle - thereby providing continuous output of finished components.

Leader Chuck Systems' display will also highlight the award-winning MultiChuck MMY concentric clamping system, along with the MultiVice MMX inline vice and MMCC multi-jaw vice systems, and the MMXZ and MMCZ modular vice strips.

All are designed for use on machining centres, milling machines and grinders, In addition, the company's display will show examples from its range of high-accuracy Hainbuch collet chucks, which will accommodate workpieces up to 500mm diameter.

These include the new Mando Adapt and Jaw Adapt systems - which effectively transform a standard Hainbuch Combi Pull Back chuck into a mandrel and jaw chuck - and Lexon, an economical collet chuck replacement for multi-bore and other styles of collet chucks in bar-fed turning applications.

As well as featuring examples from the company's comprehensive portfolio of own-brand standard CNC power chucks (165mm to 315mm diameter) and self-contained compact static and rotating air chucks (80mm to 315mm) Leader Chuck Systems will also highlight chucks from Gamet, Hewa, MicroCentric and Zweifel, for which it also holds the exclusive UK agency rights.
