ABSTRACT:
An apparatus for the non-circular peripheral machining of an out-of-round workpiece includes a lathe spindle for rotating the workpiece; a radially displaceable tool holder for carrying a tool to engage a peripheral face of the workpiece; a first and a second setting motor for displacing the tool holder in a radial direction during rotation of the lathe spindle; a first connecting device coupling the output of the first setting motor with the second setting motor and the tool holder for displacing, with incremental steps, the second setting motor and the tool holder as a unit in the radial direction; and a second connecting device coupling the output of the second setting motor with the tool holder for displacing, with incremental steps--that are of different magnitude from those of the first setting motor--the tool holder in the radial direction relative to the first connecting device and the first setting motor.
