Before use, soft jaws should be machined (bored) in situ on the chuck to compensate for mounting tolerances and achieve maximum concentricity — a soft jaw machined in situ exceeds the precision of any standard hardened jaw.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre these Ø 630 mm jaws compatible with my chuck?\u003c\/summary\u003e\n\u003cp\u003ePS3\/PS4 jaws are designed for 3 or 4-jaw chucks with PS type mounting — check compatibility with your chuck before purchase. The Ø 630 mm diameter indicates the chuck size for which the jaws are designed. Also check the number of mounting bolts on your chuck.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan monolithic jaws be reversed for external gripping?\u003c\/summary\u003e\n\u003cp\u003eNo — monolithic jaws are not reversible. For external gripping (clamping from the outside of the workpiece), reversible top jaws from the TJ or DTJ series are required. Monolithic jaws are only available in versions for internal gripping or only for external gripping — check the type before purchase.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDelivery times?\u003c\/summary\u003e\n\u003cp\u003eOriginal spare parts available with 3–5 working days shipping.
