Our patented power chuck with through-hole

HWR has responded to the development of modern machine tools and developed the flexible chuck INOFlex®. INOFlex® permits compensating centric clamping of round, rectangular and also geometrically unshaped parts.

Affordable &
flexible all-rounder

Ranging from Ø 160 – 1200 mm, INOFlex® combines the advantages of the 2-, 3-, 4-jaw chuck and vice, and through its patented compensation features it avoids the disadvantages such as the over-determinedness.

  • Clamping of round, square/ rectangular and irregular parts
  • Suitable for deformation-sensitive parts
  • For open centre or partial open centre clamping
  • Internal and external clamping

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), 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 gate-type gear. The compensating technology allows round, square and geometrically irregular workpieces to be machined concentric to the clamping device/ rotary axis in turning and milling operations.
