摘要： The invention concerns a machine tool for the bevelling of a gear, in which two topfaces are simultaneously milled, with a rotationally driven workpiece carrier and two rotationally driven mounting spindles (13) which can be placed on the workpiece in an axial direction and whose rotationally driven angle of orientation towards the workpiece axis is adjustable in order to receive a milling machine at any one time, especially face milling cutters or single-tooth fly cutters. The workpiece is alternatively clocked or rotationally driven in a continuous manner and the mounting spindles (13) can be moved on a forwards or backwards axis in synchronization with the workpiece cycle or in synchronization with the continuous rotation of the workpiece on a fixed axis. The workpiece is moved forwards in the direction of the axis and each mounting spindle (13) is provided with a slide (12), which can be moved by an axial displacement drive (15). In order to obtain short operation times and quick, easy resetting of the machine tool during modification of the machining process the invention proposes that the tool feed should be determined during the machining process by the form of a replaceable axial radial cam (17), which is rotationally driven by an axial displacement drive (15) and whose stroke corresponds at least to the machining section, in which both flanks (20) of the axial radial cam (17) are placed between the jockey rollers (21) of the slide (12), free from backlash.

摘要： The invention relates to a machine tool for the processing of rotating tools by means of a rotary driven tool (13), impact hammers in particular, operating in synchronization with a work piece (4), for the placing of an indentation, whereby the work drive (9) and the tool drive (14) are maintained by means of electronic control in synchronous operation above each corresponding rotary transducer with one of the corresponding drive (9, 14) servomotors (26) in order to influence the phase positions of both drives (9, 14). In order to achieve phase opposition with little expenditure of energy the invention proposes that a sensor device (21) of one of the two rotary transducers (15, 19) can be adjusted and turned towards the stator (10) of the appropriate drive motor (9).
