Problems solved by technology

[0003] At present, the popularity of high-precision glass grinding wheels in Japan and South Korea is much higher than that in China. The high-precision grinding wheels in Japan and South Korea are mainly sintered. Due to the limitation of the preparation process, the diamond holding force is low, the diamond exposure is low, and the chip removal is poor, resulting in service life and effect. Unsatisfactory; domestic electroformed precision grinding wheels, poor machining accuracy and electroplating solutions that pollute the environment. The diamond abrasive grains and the bonding agent are mechanically embedded and bonded, which is easy to cause shedding under normal grinding, resulting in failure

Abstract

The invention discloses a brazing type diamond grinding wheel used for high-precision grinding and a manufacturing method and belongs to the technical field of precise grinding of high-end glass and material grinding. A diamond brazing layer is arranged at the upper portion of a metal machine body. Diamond abrasive particles are arranged in the diamond brazing layer. Micro grooves are formed in the surface of the metal machine body and are arranged in the surface of the metal machine body in an ordered or disordered manner. The diamond brazing layer comprises an outer circle face and grinding grooves, and the shape of the grinding grooves is determined according to workpiece machining requirements. By means of the brazing type diamond grinding wheel, the number and the diameter of the grooves can be customized at will; and the diamond abrasive particles are subjected to multi-layer brazing; the diamond abrasive particles maintain high holding force in the highly-bare state, and the service life is long. Compared with sintering type and electroplating type manufacturing technologies, the service life is greatly prolonged, and the machining quality is greatly improved; and the diamond abrasive particles still have the high holding force in the highly-bare state, a collapse opening of an outer circle of ground glass is smaller, and the service life is obviously prolonged.

Description

technical field [0001] The invention relates to a brazed diamond grinding wheel for high-precision grinding and a preparation method thereof, belonging to the technical field of high-end glass precision grinding and abrasive materials. Background technique [0002] The good development prospect of the glass deep processing industry is the source of the rapid development of my country's glass machinery manufacturing industry. The continuous updating of high-end glass such as ultra-thin panel glass has made its finishing more and more difficult. Before formal installation of panel glass, etc., the chamfering of the outer edge of the glass and the shaping of special parts are required. This part of the processing can only be carried out by high-precision grinding wheels. [0003] At present, the popularity of high-precision glass grinding wheels in Japan and South Korea is much higher than that in China. The high-precision grinding wheels in Japan and South Korea are mainly sin...
