The abrasives industry is a basic industry, but mechanical processing always occupies its important position. As far as abrasives are concerned, three improvements and breakthroughs are of great significance. 

First, the physical structure of the abrasive is improved, such as increasing the number of abrasive particles acting on the workpiece per unit time, increasing the average length of the grinding, and increasing the grinding contact surface, all of which change the amount of grinding per unit time and have an increase rate.

Second, the application of super-hard abrasive tools, mainly refers to the use of metal powder, metal oxide or CBN and other super-hard materials as fillers, and the application of resin, ceramic or metal bond to make abrasive tools. At present, the high-precision and high-rate grinding rate brought about by super-hard abrasives have been widely recognized.

Third, new types of abrasives have appeared, such as ceramic microcrystalline abrasive composed of micron polycrystalline and polyester film tape for super-finish polishing, etc. The advantages of these new types of abrasives have demonstrated their advantages in grinding processing.

Looking at the development of the grinding field, grinding process will put forward higher requirements for abrasives in the future. Judging from the current situation, superhard products can meet these new grinding needs. For example, CBN abrasive has good thermal stability, high hardness, good wear resistance, etc, so the grinding tool has high linear speed, high grinding rate, and long tool life. It is especially suitable for processing ferrous metal materials such as high-speed steel, bearing steel, stainless steel, and chilled cast iron. In addition, to meet various needs, ceramic bond grinding wheels, diamond saw blades and large hole high speed grinding wheel, etc. will expand the scope of application with the advancement of technology and become the mainstream products of grinding processing.
