Frequently asked questions

DOJ jaws Ø 125 mm — what does DOJ mean and how do they differ from DIJ jaws?

DOJ (Direct Outer Jaw) refers to external gripping jaws: the teeth grip the outer diameter of the workpiece, tightening inwards. They are the standard jaws for clamping bars, shafts, cylinders and compact shaped parts. DIJ jaws do the opposite — internal gripping on hollow parts. The same machine can use both DIJ and DOJ depending on the workpiece, as long as the chuck size is compatible.

DK12 series — compatibility with my chuck?

DK12 mounting (12 DIN 6350 bolts). Check your chuck's mounting type before purchasing — DK11 and DK12 are not interchangeable. The Ø 125 mm diameter must match the chuck size. Customer support available in Italian.

Hard DOJ jaws vs soft jaws — when to choose one over the other?

Hard DOJ jaws (hardened) are for general use on steel, cast iron, and rough aluminum — they clamp firmly without deforming but leave marks on finished parts. Soft jaws (mild steel) do not leave marks on pre-machined parts and can be turned in situ for maximum concentricity. For finishing operations on pre-machined parts: soft jaws. For roughing and production on raw parts: hard jaws.
