HWR has responded to the development of modern machine tools and developed the flexible chuck INOFlex®. INOFlex® allows compensating centric clamping of round, rectangular and also geometrically unshaped parts.
In the range from Ø 160 – 1200 mm, INOFlex® combines the advantages of the 2-, 3-, 4-jaw chuck and vice and through its patented compensation feature it avoids the disadventages such as the over-determinedness.
In a conventional chuck, all drive parts move in the same direction around the centre (e.g. wedge bar, wedge hook, scroll), 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 opposed slides with levers or a sliding sliding gate-type gear. The compensating technology allows round, cubic, geometrically irregular workpieces to be machined concentric to the clamping device/ rotary axis in turning and milling operations.
