Method allowing the in-situ machining of the peripheral surface of a rotational workpiece and device facilitating the method

摘要

The method involves utilizing a machining device comprising a plate (12) integrated to a frame and a tool holder with a cutting tool (300). The holder is mounted on the plate in order to pivot around an axis oriented along a preset direction. An active end of the cutting tool is displaced in a perpendicular plane by combining a rotation around the axis and a translation along a plunge-in direction of a rotation center of the tool. An independent claim is also included for a device for machining a peripheral surface of a rotating part such as commutator and bearing ring, of an electric motor.
