PURPOSE:To improve polishing efficiency by providing a pair of buff wheels and rotating the buff wheels in their mutually opposite directions in a polishing apparatus adapted to bring polishing surfaces of rotating buff wheels into press- contact with the surface, to be polished, of a work so as to polish the work. CONSTITUTION:Buff wheels 22, 32, the bases of which are used as polishing surface, are fixed to the points of the respective rotary shafts 21, 31 of rotational driving devices 2, 3 having a driving source such as a motor or the like. The polishing surfaces 221, 321 of the buff wheels 22, 32 are brought into press- contact with the surface, to be polished, of a work W placed on a support board 1 rotated in the direction of an arrow by a suitable means, and the work W is polished by the rotation of the respective buff wheels 22, 32. At this time, the respective buff wheels 22, 32 are rotated in their mutually opposite directions by a rotational driving device 23, so that the work W can be polished with high efficiency. |
