INOFlex® VK-S – Patented Closed Centre Power Chuck
Engineered to meet the demands of today’s advanced machine tools, the INOFlex® VK-S is a closed centre power chuck offering exceptional versatility. Its compensating design enables precise centric clamping of round, rectangular, and irregularly shaped components – making it ideal for complex machining applications.
Cost-Effective and Versatile Workholding
Available in sizes from Ø160 to Ø1200 mm, the INOFlex® combines the strengths of 2-, 3-, and 4-jaw chucks and vices in one flexible solution. Its patented compensation technology eliminates common issues like over-constrained clamping, delivering reliable performance across a wide range of applications.
-
Clamps round, square, rectangular, and irregular parts
-
Suitable for delicate, deformation-sensitive components
-
Supports both internal and external clamping
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.
