Frequently Asked Questions

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

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

DK11 series — compatibility with my chuck?

DK11 mount (11 bolts DIN 6350). Check the type of mount on your chuck 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 raw steel, cast iron, and aluminum — they clamp strongly 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 workpieces: soft jaws. For roughing and production on raw workpieces: hard jaws.
