What is the INOZet® pendulum system

The INOZet® pendulum system upgrades your chuck’s capabilities with a smart pendulum mechanism that adapts to the shape and tolerance of your components. It delivers outstanding turning results and significant cost savings by dramatically reducing distortion and setup times.

Whether you’re using a conventional 3-jaw chuck or an INOFlex® 4-jaw chuck, INOZet® transforms it into a high-performance compensating system in no time.
🔹 A 3-jaw chuck becomes a flexible 6-jaw compensating chuck
🔹 An INOFlex® 4-jaw chuck becomes an 8-jaw compensating solution

Designed to retrofit onto most existing 3-jaw chucks from 210mm diameter upwards, INOZet® gives your current setup a new lease of life – without the need for major investment.

Key Advantages:
✔ Converts existing chucks into high-performance compensating systems
✔ Exceptional turning quality and part surface finish
✔ Reduces scrap and rework caused by clamping distortion
✔ Compatible with a wide range of existing chuck sizes and brands

How the INOZet® works

The INOZet® system uses an oscillating, self-compensating mechanism beneath its 6 jaws to maintain true centric clamping. This intelligent compensation ensures that all clamping points apply equal pressure, allowing them to adapt evenly to the surface of the workpiece.

In traditional systems with more than three clamping points, a lack of compensation can result in over-determined clamping, which forces the workpiece into a distorted position – especially problematic for thin-walled components. INOZet® eliminates this risk by allowing each jaw to move slightly and independently, delivering secure clamping without deformation.

Thanks to the serrated upper surfaces of the pendulum jaws, a single set of top jaws (6 pieces) can cover the entire diameter range of the chuck. That means one jaw set is suitable for both small and large workpieces, as well as for internal and external clamping.

Both hard jaws for first operations and soft jaws for finishing can be used – making the INOZet® system a versatile solution for various machining tasks.
