PURPOSE:To reduce the cost of installation and construction and elongate the life of a worked surface by vanishing the surface receiving thrust load of a rotary shaft with a working roller secured fixedly to a shaft supported by a housing attachable to a lathe or the like. CONSTITUTION:The bracket section 1b of a housing 1 is attached to a tool rest of a lathe, and a work W is attached to a spindle of the lathe. The outer peripheral surface of a working roller section 3a of a working roller 3 contacts linearly a surface f' to be worked of a work W (surface receiving thrust load) with a predetermined press force, while the working roller 3 is driven to rotate by the rotation of the work W. Then, between the outer peripheral surface of the roller section 3a and the surface f' is produced a slight slip adjusted by a lock nut 9 in a screw section 2e of a shaft 2' and since the surface layer portion of the surface f' is plastically worked by the roller section 3a, since it is pressed by the predetermined press force. Thus, the front surface of the surface f' is finished to be an elaborate smooth plane. |
