Abstract
The machine includes a saddle (26) which is displaceable along a spindle axis (E) and transversely thereof under numerical control. A tool spindle (28) is supported on the saddle (26) so as to be driven in rotation about the spindle axis (E) and adapted to be equipped with a disc-shaped tool for cutting work to be done on a workpiece (10). The machine further includes a workpiece slide (42) which is displaceable along the workpiece slide guide (40) under numerical control and carries a workpiece support (44). The tool (30) is embodied by an electrically conductive member of an electric circuit (30, 36, 46, 48, 10) which is closed through the workpiece (10) when this is touched by the tool (30). The tool spindle (28) is adapted to be driven by a motor (84) which can be switched from a rotational operating speed to do cutting work on the workpiece (10) to a rotational measuring speed which is considerably slower. The numerically controlled possibilities of movement, for which the machine is equipped anyway, enable the measuring unit to pick up dimensions required for recognizing and machining workpieces having cutting teeth, especially circular saw blades and to do so in a manner sui…
