Bore Clamp

The bore clamp is particularly suitable for centring and clamping of workpieces with smoothly machined bores with diameters from 16 to 46 mm and a support surface square to the hole axis.

The bore clamp is a combination of a double-acting pull-type cylinder equipped with a segment clamping bushing, which is pulled by a tie rod over a fixed cone. Thereby the segment clamping bushing expands radially to the bore diameter of the workpiece to be clamped. By the simultaneous axial movement the workpiece is clamped onto the hardened support at the housing. The obtainable low-clamping force depends on the factor of friction within the bore and the operating pressure.
