PCT No. PCT/EP89/00619 Sec. 371 Date Jan. 11, 1990 Sec. 102(e) Date Jan. 11, 1990 PCT Filed Jun. 2, 1989 PCT Pub. No. WO89/11951 PCT Pub. Date Dec. 14, 1989.A drilling and milling machine comprises a travelling pillar (20) having a tool spindle (25) which is movable along its own spindle axis (Z) and along the two further axes (X, Y) of a three-dimensional coordinate system (X, Y, Z), and a workpiece carrier (30) which is stepwise rotatable about a pivot axis (A). The pivot axis (A) extends horizontally and at right-angles to the spindle axis (Z). The workpiece carrier (30) is constructed for clamping a material bar (18), the axis of which coincides with the pivot axis (A) and the end portion of which forms a workpiece (18') to be machined by the workpiece spindle (25). On the travelling pillar (20) a severing unit (26) is arranged which in each operating cycle severs a machined workpiece (18') from the workpiece bar (18). The resulting partition face can then be further machined by the drilling and milling machine.
