Chuck JF Chuck JF Reinox
The original, further improved in our factory over many decades; Used worldwide on all types of measuring machines.
If desired, we can grind the steps of your clamping jaws to the workpiece diameter you define and thus achieving surface clamping (instead of line support) which leads to the workpiecebeing held even better in its shape during clamping.
