The workpiece carrier (16) is fixed to a turntable (15) on a horizontal slide (14) with the turntable being pivoted around a vertical axis (A). After the turntable (15) has been brought into an inclined position, the crankshafts (10, 10a) are provided with oblique drill holes by means of the drills (26, 26a). A tool magazine (32) comprises a first circulating magazine (33) for drilling tools and a second circulating magazine (34) for drill bushings (27, 27a). The tools are exchanged between tool magazine (32) and spindle box (24) by means of the pick-up process.
