A kind of diamond grinding wheel and its production method

Abstract

The invention discloses a diamond grinding wheel, which has multi-layer abrasive particle orderly arrangement, is high in bonding strength and is convenient to repair after being worn, and a production method thereof. The production method comprises steps of processing a grinding wheel basal body, cleaning and the like. According to the diamond grinding wheel and the production method thereof disclosed by the invention, a laser material increasing technology is adopted to accurately process, so that processing precision and processing quality are improved; a sandwich structure is adopted for sintering, so that the abrasive particles are prevented from moving, protruding height of the abrasive particles is guaranteed to be consistent, orderly arrangement of the diamond abrasive particles is realized, a chip space during grinding is great, grinding force is reduced, a grinding temperature is reduced, grinding efficiency is improved, and grinding surface quality is improved; power of a laser unit is controlled for controlling a sintering temperature, so that the diamond abrasive particles are prevented from graphitizing, and a metal bonder is combined with the diamond abrasive particles in a high-strength metallurgical mode; a manufacturing process further can be simplified; and the diamond grinding wheel is finished layer by layer after being worn, and then is continuously used, so that finishing is convenient, and the service life of the diamond grinding wheel is long.

Description

technical field

[0001] The invention relates to an abrasive abrasive tool, in particular to a diamond grinding wheel and a production method thereof. Background technique

[0002] Using diamond abrasives as raw materials, metal powder, resin powder, ceramics and electroplated metals are used as binders respectively, and the circular bonded abrasive with a through hole in the center is called a diamond grinding wheel. Due to the characteristics of diamond abrasives (high hardness, high compressive strength, and good wear resistance), diamond abrasives become an ideal tool for grinding hard and brittle materials and cemented carbide in grinding processing. High, good roughness, less consumption of abrasive tools, long service life, and improved working conditions at the same time. Therefore, it is widely used in metals with low iron content and non-metallic hard and brittle materials that are difficult to process with ordinary abrasive tools, such as cemented carbide, high al...
