Two jaw technology: a small solution to a big problem

Irrespective of shape or size – round, cubic, small or large – with the modular system users can clamp any kind of workpiece; and the various adaptation clamping devices can be changed over rapidly. The Marbach, Germany-based workholding specialist is constantly adding to its modular system so that users can always find the optimum solution for every clamping situation.

However, one thing was still missing: an adaptation for clamping cubic parts, which is why Hainbuch has introduced the two-jaw module to the market.

Round workpieces are clamped externally with classic clamping heads, but when these reach their limits with larger diameter workpieces that need to be clamped, then the three-jaw module is used. And for cubic parts, the two-jaw module is used for centric clamping in machining centres and milling machines.

In just two minutes, it is possible to changeover from external clamping to centric clamping – and the two-jaw module can even be used at speeds of up to 1,500rpm. Due to its compact, lightweight design, Hainbuch says it is the perfect alternative to a large and heavy centric clamping device.

The basic unit into which the jaw module is inserted is a Hainbuch chuck or vice. Modules can be exchanged without changing the clamping device and, thanks to the integrated Centrex quick-change interface, no alignment is needed.

The Hainbuch solution with its chucks or vices and jaw modules is a long way from the bulky, large, heavy vices found on many shop floors. Often, this results in using an excessively large chuck to hold small workpieces.

This immediately causes a dilemma because it often means the tools are hard to access. In these instances it’s not unusual to use special tools, but this comes with a high risk of collision. By comparison, Hainbuch reports that its modular system is far more efficient, and just as capable of multitasking as machine tools are nowadays.
