Claims (1)

[Claim for Utility Model Registration] A substantially circular plate that is provided at the tip of a shank and is driven and rotated through the shank for surface finishing and polishing of materials to be polished such as stone, building materials, metals, and glass. A plurality of chips are arranged along the radial direction from the inner circumferential side to the outer circumferential side of the wheel on the wheel surface of the shaped wheel, and the chips are arranged radially as a whole, and each of the chips is individually arranged. By providing a low-hardness abrasive body having a lower hardness than the high-hardness abrasive body between two high-hardness abrasive bodies, the tip surface of the chip that should be in contact with the material to be polished is a high-hardness abrasive surface and a low-hardness abrasive surface. In a polisher chip consisting of an abrasive surface;
The area of the low hardness polished surface 3 on the outer peripheral side O is smaller than the area of the low hardness polished surface 3 on the inner peripheral side I. A polisher tip characterized by having a The low-hardness abrasive surface 3 has a band shape extending along the radial direction of the wheel 5 on the chip surface 2, and is also wavy on the chip surface 2, and has crests T of the waves. Claim 1, characterized in that the distances L1, L2, L3, L4, L5, .
Chip for polisher as described in section. The low-hardness abrasive surface 3 has a band shape extending along the radial direction of the wheel 5 on the chip surface 2, and is also wavy on the chip surface 2, and has crests T of the waves. The height H1 of each
, H2, H3, H4, H5, H6... are formed to become smaller from the inner circumferential side I toward the outer circumferential side O. Chip. The low-hardness abrasive surface 3 has a band shape extending along the radial direction of the wheel 5 on the chip surface 2, and the low-hardness abrasive surface 3 is in the form of a band.
The polisher according to claims 1, 2, and 3, wherein the width H' of the polisher is formed so as to become continuously smaller from the inner circumferential side I toward the outer circumferential side O. Chip for use.
