Thus, a part of each feed-lapped polishing piece is bent and deformed according to the shape of the concave curved surface, and the work of each shape can be effectively polished. Especially,
When polishing the inner surface of a recess such as a groove or valley having an angular inner corner, the protrusion of the folding polishing piece that protrudes into the recess is bent and deformed according to the cross-sectional shape of the recess and becomes dense within the recess. Since each folded polishing piece slides in contact with the inner surface of the recessed portion in the fitted state, the inner corner of the recessed portion can be effectively polished, and the entire recessed portion can be uniformly and effectively polished. Therefore, it is possible to improve the efficiency and labor of the polishing process for the work having the recesses of each shape. In addition, the production of polishing discs can be simplified, and the number and size of folding polishing pieces can be arbitrarily selected according to the shape and material of the work piece, and the folding piece has flexibility to adapt to polishing work of various works. A polishing part can be formed.

In this example, the disk body is cut in a radial direction from each of the starting points 6 that equally divides the circular outer peripheral edge 10a of the polishing sheet 10 into a plurality of arcs toward the center 4 of the polishing sheet 10. Each piece 8 formed between the cuts 5 is connected to an inner end 7 of the cut 5 that is adjacent to the cut 8 on the rotation direction side and a starting point 6 of the cut 5 that is adjacent to the cut 8 on the opposite rotation side. Fold the diagonal line 9
As a result, a plurality of folded polishing pieces 11 each of which is folded back into two and shaped are arranged in a rotationally symmetrical manner in the circumferential direction.

クＷをそれぞれ有効に研磨加工することができる。For this reason, when the polishing disk D is rotated to polish the work W having the concave curved surface W1, the folding polishing pieces 11 are sequentially pressed firmly against the concave curved surface W1 of the work W by centrifugal force to feed each workpiece. Since a part of the overlaid polishing piece 11 is bent and deformed according to the shape of the concave curved surface W1, the work W of each shape can be effectively polished.

省力化することができる。In particular, as shown in FIG. 7, when the inner surface of the groove M having a right-angled inner corner is polished, the protrusion 11a of the folding polishing piece 11 that protrudes into the groove M has the same cross-sectional shape as the groove M. Since each folded polishing piece 11 slides in contact with the inner surface of the groove M in a state of being bent and deformed to be tightly fitted in the groove M,
The inner corners of the groove M can be effectively polished, and the entire groove M can be uniformly and effectively polished. Therefore, it is possible to improve the efficiency and labor of the polishing process for the work having the recesses of each shape.
