Frequently Asked Questions

DOJ Jaws Ø 630 mm β€” what does DOJ mean and how do they differ from DIJ jaws?

DOJ (Direct Outer Jaw) indicates jaws for external gripping: the teeth grip the workpiece from the outside diameter, clamping inwards. These are the standard jaws for clamping bars, shafts, cylinders, and compactly shaped workpieces. DIJ jaws do the opposite β€” 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 β€” compatibility with my chuck?

DK12 mounting (12 bolts DIN 6350). Verify your chuck's mounting type before purchase β€” DK11 and DK12 are not interchangeable. The Ø 630 mm diameter must match the chuck size. Customer support available in Italian.

Hard DOJ jaws vs. soft jaws β€” when to choose one over the other?

Hard DOJ jaws (hardened) are for general use on rough steel, cast iron, and aluminum β€” they grip forcefully without deforming but leave marks on finished workpieces. Soft jaws (mild steel) do not leave marks on already machined workpieces and can be machined in-situ for maximum concentricity. For finishing operations on already machined workpieces: soft jaws. For roughing and production on raw workpieces: hard jaws.
