ABSTRACT:
The invention relates to a method for tooth-machining of workpieces (3), especially gear wheels, comprising milling, deburring by hobbing and integrated secondary deburring. The method proceeds on a machine tool (1) having two workpiece spindles (11, 12) which may exchange places. A workpiece (3) is mounted on a first workpiece spindle (11), followed by the workpiece spindles (11, 12) exchanging places, followed by pre-milling and, where applicable, cutting (=deburring by shaving) of the workpiece (3), followed by a further exchange of places, followed by chamfering and cutting of the workpiece (3), followed by a further exchange of places, followed by a finish-milling of the workpiece (3), followed by a further exchange of places, followed by a workpiece change. At the same time, the same procedure takes place on the second workpiece spindle (12), staggered in time by an exchange of places of the workpiece spindles (11, 12). With the method according to the invention, well-deburred toothed workpieces (3) may be produced quickly and at low cost.
