INOFlex® VF-A : THE PLUS IN INNOVATION

With the new type for automated worpiece changing, HWR expands its range of applications and now offers even greater flexibility. The hydraulic actuation enables workpieces to be changed quickly and presciely, which significantly increases productivity, especially im automated operations.

INOFlex® – A Cost-Effective, All-Purpose Workholding Solution

Offered in diameters from Ø160 to Ø1200 mm, the INOFlex® combines the benefits of 2-, 3-, and 4-jaw chucks with the versatility of a vice. Its patented compensation system eliminates the limitations of over-constrained clamping, ensuring reliable and repeatable performance across a wide range of applications.

  • Ideal for round, square, rectangular, and irregularly shaped parts

  • Suitable for delicate or deformation-prone components

  • Compatible with open and partially open centre setups

  • Enables both internal and external clamping

How the INOFlex® System Works

Unlike traditional power 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.

The HWR INOFlex range is fully compatible with the HWR INOZet – You can learn more about the INOZet here –
