Frequently asked questions

Soft monobloc jaws Ø 80 mm — when are they used instead of hardened jaws?

Soft jaws (made of unhardened mild steel) are used when the workpiece cannot be scratched or deformed by the jaw — finished surfaces, soft materials (aluminum, copper, plastic), thin-walled workpieces. Before use, the soft jaws must be machined (bored) in situ on the chuck to compensate for assembly tolerances and achieve maximum concentricity — a soft jaw machined in situ exceeds the precision of any standard hardened jaw.

Are these jaws for Ø 80 mm compatible with my chuck?

PS3/PS4 jaws are designed for 3 or 4-jaw chucks with PS type mounting — check compatibility with your chuck before purchasing. The Ø 80 mm diameter indicates the chuck size for which the jaws are designed. Also check the number of mounting bolts on your chuck.

Can monobloc jaws be reversed for external gripping?

No — monobloc jaws are not reversible. For external gripping (clamping from the outside of the workpiece), reversible top jaws of the TJ or DTJ series are required. Monobloc jaws are only available in internal gripping or external gripping versions — check the type before purchasing.
