A transfer line for machining differential housings, in which the outer surface of the workpiece is clamped against angled locating surfaces in each work rest. The workpiece is rotated through 90.degree. and located against a work rest in a successive machining station which is oriented 90.degree. to the first mentioned work rest locating surfaces so that the same locating points on the workpiece are used for locating in the successive machining station despite the workpiece having been rotated to enable machining from a different angle.

Transfer line for machining workpieces especially for machining

A clamping arrangement is disclosed for an annular milling cutter comprises a receiving flange which has a centering collar concentric with the axis of rotation. With the aid of clamping means the milling cutter is held on the receiving flange and positively connected to the latter by at least one engaging member. To enable the gripper of a tool changer to have unobstructed access, a pressure flange carrying a number of radially protruding teeth on its rim is provided, axially movable by an actuator rod selectively operated by an actuator. The milling cutter has in its central opening radially inwardly protruding teeth, the spacing of which corresponds to the spacing of the teeth on the pressure flange. By setting the position of the teeth offset relative to one another, the milling cutter can be moved over the pressure flange, and rotating the cutter to align the teeth, the pressure flange can clamp the milling cutter against an abutment surface on the receiving flange, acting through the aligned teeth.
