7) The workpiece (W) group received on the top descends by its own weight along the descending path (A), and when the workpiece (W) descends by one piece, the delivery part (51) protrudes. It is received by the control bar (57) being operated and stopped, and the state shown in FIG. 5 is restored. After that, the above operation is regularly repeated by a timer or the like, and the workpiece (W) is fed from the feeding device (35) to the feeding device (6).
It is sequentially sent to the polishing space (34) through (3), held there for a predetermined time, deburred and polished, and then fed in.
By the 90 ° intermittent rotation of the rotary arm (64) of (63), the processed workpiece (W) is carried by the rotation of the rotary arm (64) and is fed downward from the polishing space (34). On the way, it is separated from the feed guide section (65), falls on the chute (74), and is carried out to the next step. It can be applied even in the case of a straight shape where the outer diameter of the workpiece is constant.
