Frequently asked questions
DOJ jaws Ø 80 mm — what does DOJ mean and how do they differ from DIJ jaws?
DOJ (Direct Outer Jaw) refers to external grip jaws: the teeth bite from the outside of the workpiece diameter, clamping inwards. These are standard jaws for clamping bars, shafts, cylinders, and compact-shaped workpieces. DIJ jaws do the opposite — internal grip on hollow workpieces. The same machine can use both DIJ and DOJ depending on the workpiece, provided the chuck size is compatible.
DK11 series — compatibility with my chuck?
DK11 mount (11 DIN 6350 bolts). Check your chuck's mount type before purchasing — DK11 and DK12 are not interchangeable. The Ø 80 mm diameter must match the chuck size. Customer support in Italian available.
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 strongly without deforming but leave marks on finished workpieces. Soft (mild steel) jaws 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.
