Grinding disc and fixing method of tool bit on grinding disc

Abstract

The present application is used in the field of grinding tools, and particularly relates to a grinding disc and a fixing method of the cutter heads on the grinding disc. The grinding disc comprises a base disc, a plurality of hole positions are arranged on the base disc near the edge, and each hole position is arranged on the base disc in a ring direction. The cutter heads are arranged in a plurality of numbers, one cutter head is fixed between every two adjacent hole positions, and every two adjacent cutter heads are spaced from each other. The cutter heads are spaced from each other to form a chip groove, which facilitates the discharge of the chips in the grinding process. The edge of each cutter head forms a cutting edge in the grinding process, so that the grinding capacity is stronger, and the sharpness of the cutter head is higher. The fixing method of the cutter heads on the grinding disc comprises the following steps: arranging the cutter heads between every two adjacent hole positions on the base disc, and exposing the two ends of the cutter heads in the adjacent two hole positions; welding the part of the cutter heads exposed in the hole positions in the hole positions; and repeating the above steps until a plurality of spaced cutter heads are fixed and welded on one side of the base disc. Compared with the sintering fixing method, the welding fixing method of the cutter heads has lower energy consumption in the manufacturing process.
