PURPOSE:To drastically shorten a work processing time spent for a high precise finishing, by executing the burnishing of an oil seal face with the use of the diamond burnishing tool carried together with a cutting tool, after cutting the surface of a shaft by this tool. CONSTITUTION:A rough machining and finish machining are executed on the axial part (b) of a crankshaft W with one or plural cutting tools 1 first for the crankshaft W formed by casting. A tooling head 3 is then rotated, burnishing is executed on an oil seal face (a) by a carried diamond burnishing tool 2 and the surface thereof is finished highly precisely. The oil seal face (a) becomes smooth accordingly and the unevenness causing an oil leakage, etc., is removed without exception. |
