Problems solved by technology

However, when the dry-type diamond grinding disc is used for high-speed grinding, the high-speed rotation will cause the sand and gravel dust to not be discharged in time and block the grinding surface of the cutter head. Since the dry-type diamond grinding disc does not use water as the cooling medium, it is urgent to design a more Dry diamond grinding disc with excellent chip removal performance and heat dissipation performance

Abstract

The invention discloses a high-speed grinding diamond grinding disc and a manufacturing process thereof, and belongs to the technical field of diamond grinding discs. A plurality of diamond tool bitsof the diamond grinding disc are arranged on the working face of a grinding disc steel base body, the grinding disc steel base body comprises an outer side annular plane and an inner side annular plane, a middle annular face is arranged between the outer side annular plane and the inner side annular plane, first tool bits and second tool bits of the diamond tool bits are arranged on the outer sideannular plane and are arranged on the outer side annular plane in a staggered mode in the circumferential direction, the tool bits are of arc-shaped strip-shaped plate structures, and the curvature of the tool bits is the same as that of the outer edge of the grinding disc steel base body. According to the high-speed grinding diamond grinding disc and the manufacturing process thereof, through the optimized design of a base body structure, chip removal and heat dissipation holes in special shapes are designed in the base body so that chip removal, heat conduction and heat dissipation of the grinding disc can be more effectively achieved, the problem that water cannot be used for grinding construction operation in a cooling construction environment can be solved, performance can be well kept for continuous use, and vast users can operate and construct more conveniently.

Description

technical field [0001] The invention relates to the technical field of diamond grinding discs, in particular to a high-speed grinding diamond grinding disc and a manufacturing process thereof. The diamond grinding disc is mainly used for grinding building materials (concrete, reinforced concrete, etc.) and stone materials. Background technique [0002] Diamond grinding disc refers to the disc abrasive tool used on the grinding machine. It is composed of a disc body and a diamond grinding block. The diamond grinding block is welded or embedded on the disc body, and the working surface is smoothed and polished by the high-speed rotation of the mill. [0003] Due to the characteristics of high hardness, high compressive strength, and good wear resistance of diamond abrasives, diamond abrasives have become ideal tools for grinding hard and brittle materials and cemented carbide in grinding processing, not only high efficiency, high precision, Moreover, it has good roughness, les...
