Frequently asked questions

DOJ Ø 200 mm jaws — what does DOJ mean and how do they differ from DIJ jaws?

DOJ (Direct Outer Jaw) indicates jaws for external gripping: the teeth bite from the outside of the workpiece diameter, clamping inwards. These are standard jaws for clamping bars, shafts, cylinders, and compact-shaped pieces. DIJ jaws do the opposite — internal gripping on hollow workpieces. 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 the mounting type of your chuck before purchase — DK11 and DK12 are not interchangeable. The Ø 200 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 (hardened) DOJ jaws are for general use on raw steel, cast iron, and aluminum — they clamp firmly without deforming but leave marks on finished workpieces. Soft jaws (mild steel) do not leave marks on already machined workpieces and are turned in situ for maximum concentricity. For finishing operations on already machined parts: soft jaws. For roughing and production on raw parts: hard jaws.
