Chuck JF Chuck JF Typ A
Industries:
Suitable for:
Surface clamping from the inside for easier processing of metal workpieces and precise measurements of components.
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.
