INOFlex VL with centrifugal force compensation

The INOFlex® VL is a weight-reduced, 4-jaw manual chuck designed for precision and performance at high speeds. Featuring centrifugal force compensation, it delivers exceptional clamping force with minimal loss – even under demanding conditions.

  • CENTRIFUGAL FORCE COMPENSATION
  • highest speeds in its class
  • now even higher clamping forces
  • low overall height
  • highest variety of sizes
  • 2 + 2 centrically compensating clamping
  • centric clamping with 2 jaws
  • clamping with 1 or 2 fixed stops
  • low maintenance thanks to sealing construction
  • minimal clamping force loss thanks to centrifugal force compensation
  • precise, efficient with high repeat accuracy
  • high table loading due to weight-optimized chuck body

INOFlex® VL – Where Flexibility Meets Precision

Designed for the demands of modern machining, the INOFlex® VL now features centrifugal force compensation for even greater performance at speed. This advanced 4-jaw chuck offers compensating centric clamping for round, square, rectangular, and irregularly shaped parts – all with high precision and minimal deformation.

Available in sizes from Ø160 to Ø1200 mm, it brings together the benefits of 2-, 3-, and 4-jaw chucks and vices, while its patented design eliminates the drawbacks of over-constrained clamping.

  • Hydraulic actuation

  • Suitable for delicate or thin-walled components

  • Internal and external clamping

  • Can be used as a centring vice with just two jaws

  • Made in Germany

How the INOFlex® System Works

Unlike traditional chucks where all jaws move symmetrically in or out from the centre, the INOFlex® operates on a unique concept. Its four jaws move along two parallel axes, either towards or away from each other. This motion is mechanically linked using a system of levers or a sliding gate-style gear, allowing opposing jaws to compensate as needed.

This patented compensating mechanism enables precise centric clamping of round, square, and unevenly shaped components – making it ideal for turning and milling operations that demand high accuracy.
