Abstract
A honing machine for super finishing workpieces, e.g. by honing using a tool spindle (7), can be rotatably driven and can receive a tool. A motor rotates the tool spindle, the tool spindle (12) being arranged on a carriage (12), which can be displaced on a machine frame (16), by means of a drive device, in the direction of the rotational axis of the tool spindle. The drive device consists of a flat primary part (13) and a secondary part (17) of an electric linear motor (18), the secondary part being linearly displaceable along the primary part. One (13) of the components primary part/secondary part (13, 17) of the linear motor (18) is disposed on the machine frame (16), and the other (17) on the carriage (12).
Claims4
1-3. (canceled)
A machine for superfinishing tools through honing or precision grinding, the machine comprising:
- a spindle housing;
- a honing spindle disposed in said spindle housing;
- a first electromotor having a stator integrated in said spindle housing and a rotor borne for rotation within said stator, said rotor surrounding and rotating said honing spindle;
- a linear motor having a moving part bearing said spindle housing for controlling a stroke motion of said honing spindle;
- a bar disposed within said honing spindle for rotation therewith;
- a second electromotor coaxially flanged to an end of said spindle housing, said second electromotor communicating with said bar for axial displacement thereof to widen a honing tool disposed on said honing spindle or to carry a grinding body.
