| 摘要 |
The invention relates to a drive device (1) for a wire erosion machine with a rotating indexing spindle (3) driven by a motor (2) and a current transfer device (10) for transferring current to a rotating or indexed workpiece (4) for erosive machining or a statically indexed cutting task, wherein the rotating indexing spindle (3) has a workpiece holder (5) for holding the workpiece (4) to be machined. According to the invention, the current transfer device (10) is constructed as at least one sector (10a, 10b, 10c, 10d) of an annular cylinder in which the inner surface (11) has radially running electrically conducting filaments (12) to supply the current and the current transfer device (10) is arranged in such a manner that the distal ends of the electrically conducting filaments (12) make an electrical contact with the rotating and indexing spindle (3). |
