Abstract
The polishing machine of the present invention is capable of moving a work away from a center roller and a guide roller without reference to other members. In the polishing machine, a circular polishing plate is capable of revolving so as to polish works. A center roller is capable of revolving. Guide rollers are arranged around the center roller and capable of revolving, wherein each work is rotatably held between each guide roller and the center roller. An arm shaft is provided in the vicinity of the polishing plate and capable of moving in the longitudinal direction. A work head is provided to the arm shaft and capable of holding and releasing the work. A driving mechanism moves the arm shaft so as to move the work head between a discharge position and a specified position. A releasing mechanism slightly moves the arm shaft in the longitudinal direction so as to slightly move the work away from the center roller and the guide roller.
