PURPOSE:To provide satisfactory surface finish by buffing a die formed product while abrasive grain added polishing fluid is fed using a buffing device with a rotating shaft in the surface finishing process of the die formed product. CONSTITUTION:An automobile wheel 1 is fixed horizontally on a rotary table 11 with its center aligned with the rotating center O-O of the table 11 and its design surface 2 faced upward. Also the lower end surface of a buff 13 installed at the lower end of a rotating shaft 12 is made in contact with the design surface 2. Then the rotary table 11 is rotated at a low speed while abrasive grain added polishing fluid is fed, and the buff 13 is rotated to polish the design surface 2. The rotating direction of the rotary table 11 is reversed at proper intervals, and the work portion is moved gradually in the circumferential direction. The buff 13 is formed with flexible material, for example, continuously foamed sponge, etc., with a foam ratio of approx. 3 to 5 times. |
