InoFlex® - Concentric and compensating 4-jaw chuck

The trend is towards combined turning and milling machines for both round, rectangular and geometrically irregular parts. In the past, companies have used rigid concentric 3-jaw chucks for clamping round parts and worked with vices (two jaws) for rectangular and geometrically irregular parts.

HWR has reacted to this development and produced the first universal clamping tool for clamping round, rectangular and also geometrically irregular parts. With the patent application dated January 2013 for the concentric and compensating 4-jaw chuck InoFlex, HWR is launching a clamping tool to perform this task in a range of Ø 160-1200 mm. No other clamping tool on the market can do this!

InoFlex® – for the concentric and compensating clamping of round, rectangular and geometrically irregularly shaped parts.


How it works

In a conventional chuck, all drive parts move in the same direction around the centre (e.g. wedge bar, wedge hook, scroll chuck) either towards or away from the centre.

The drive of the InoFlex® 4-jaw chuck (concentric compensation) moves towards or apart on two parallel axes. Compensation is provided by connecting the diametrically arranged slides with levers or a sliding gate-type gear.
