    摘要： A finishing device includes a finishing belt, a finishing belt holding device, a first drive configured to rotationally drive a workpiece about a workpiece axis, and a second drive configured to oscillate the workpiece and the finishing belt relative to another along the workpiece axis. The finishing belt holding device has a holding section configured to hold a portion of the finishing belt. The portion has an active area configured to finish a circumferential workpiece surface. The portion extends in a plane which is vertical when referring to the direction of gravity and extends in a horizontal direction when referring to the direction of gravity and when viewing in the running direction of the finishing belt. The finishing device includes a workpiece holding device defining a workpiece holding axis which is vertical when referring to the direction of gravity.

    摘要： The invention relates to a process and a device for dressing truncated conical tips of electrodes (1, 2) in a spot welding gun, press or the like. According to the process, each electrode tip is dressed both on its truncated conical lateral surface (1a, 2b) and on its end surface (1b, 2b). In a first machining step, the electrode tip is inserted into a cavity in a first tool (20, 21) for machining the lateral surface (1a, 2a) or the end surface (1b, 2b) until the other of these two surfaces comes into contact with an abutment, whereafter the electrode tip in a second machining step is inserted into a cavity in a second tool (21, 20) for machining the end surface (1b, 2b) or the lateral surface (1a, 2a) until the surface which has been machined in the first machining steps comes into contact with an abutment. The device according to the invention comprises a motor driven, rotary tool (20) for machining the truncated conical lateral surface (1a, 2a) and a second motor driven, rotary tool (21) for machining the end surface (1b, 2b) of the electrode tip. The first tool (20) is provided with an abutment for the end surface (1b, 2b) of the electrode tip, and the second tool (21) is provided with an abutment for the lateral surface (1a, 2a) of the electrode tip.

    摘要： Method for manufacturing a rotor (1) that at least comprises the following operations:
    - the clamping of a workpiece (25) in a grinding machine (27) ;
    - the performance of one or more cylindrical grinding operations whereby a rotor shaft section (10-14) is ground to the desired diameter with a cylindrical grinding disk (18);
    - the performance of one more profile grinding operations whereby a rotor body (3) is profiled with a profile grinding disk (23).
    and whereby, during the manufacture of the rotor (1) in the grinding machine (27), the workpiece (25) is not unclamped and the cylindrical grinding operations and the profile grinding operations are done with the same grinding machine (27) .
