ABSTRACT:
Method for micro-finish machining of circular arc-shaped profiled surfaces in annular workpieces utilizing a honing tool. After an initial grinding operation the profiled surfaces of the workpieces are micro-finish machined using two machining phases. During the first machining phase the workpieces are rotated at a first predetermined rotational velocity and the honing tool is pressed against the profiled surfaces at a first predetermined pressure; while during the second machining phase the workpieces are rotated at a second predetermined rotational velocity and the honing tool is pressed against the profiled surfaces at a second predetermined pressure. Furthermore, the first predetermined rotational velocity is lower than the second predetermined rotational velocity while the first predetermined pressure is greater than the second predetermined pressure.
