[0002] After the tractor rear axle housing blank is cast, milling, punching, polishing and deburring operations need to be performed. During the milling operation, a milling machine is used to mill the blank, remove most of the machining allowance and obtain a relatively accurate outer dimension. Punching is performed on a dedicated punching equipment to ensure accurate hole positions and meet design requirements. Polishing is performed on the surface of the blank to remove burrs and flash generated during the milling and punching processes and improve the surface finish.
