Frequently Asked Questions

Soft top jaws Ø 125 mm — how do they differ from one-piece soft jaws?

Soft top jaws combine the top jaw construction (hardened base body + replaceable soft top insert) with the unhardened mild steel insert. Compared to one-piece soft jaws: soft inserts are replaced separately when worn or when over-turned, without changing the base body. Compared to hardened reversible top jaws: soft inserts allow in-situ turning for maximum concentricity on delicate workpieces.

For Ø 125 mm — when is it necessary to turn (bore) soft inserts in situ?

In-situ boring of soft inserts is necessary whenever: new inserts are mounted, chuck clamping pressure is changed, or eccentricity is noted in the workpiece. For machining parts requiring concentricity better than 0.05 mm, in-situ boring is essential — it reduces runout to the physically achievable minimum with the chuck in use.

Can soft inserts be reversed for internal/external gripping?

It depends on the model: DSTJ jaws have non-reversible soft inserts (internal grip only or external grip only); STJ reversible top jaws can have soft inserts mounted in both orientations. Check the specifications for the specific model. Customer support available in Italian.
