Abrasives industry is a basic industry, but machining always occupies a very important position. As far as abrasives and abrasives are concerned, there are three significant improvements and breakthroughs.

1. Improve the physical structure of the abrasive tool

For example, increasing the number of abrasive particles per unit time, increasing the average grinding length, and increasing the grinding contact area, all of which change the grinding amount per unit time and effectively improve the efficiency;

2. Application of Superhard Abrasives

It mainly refers to the use of super hard materials such as metal powder, metal oxide or CBN as fillers, and resin, ceramic or metal bonding agents to make abrasive tools. At present, high-precision and high-efficiency grinding effects brought by super-hard abrasives have been widely recognized.

3. New type abrasives appear

Such as micron-sized polycrystalline ceramic microcrystalline abrasives, spherical diamond-containing abrasives with fine diamond abrasive grains, polyester film belts for ultra-fine polishing, etc. These new abrasive tools have the characteristics that make their grinding processing advantages fully displayed.

Looking at the development of the grinding field, the future grinding process will put forward higher requirements on abrasive tools. Judging from the current status, superhard products just meet these new grinding needs.
For example, CBN abrasives have good thermal stability, high hardness, and good wear resistance. Therefore, their abrasive tools have high linear speed, high grinding efficiency, and long tool life. They are particularly suitable for processing high-speed steel and bearing steel. Ferrous metal materials such as stainless steel, stainless steel, cold-shocked cast iron. In addition, to meet various needs, ceramic bond grinding wheels, atmospheric hole high-speed grinding wheels, different abrasive grain grinding wheels with different working surfaces, diamond saw blades, etc. will expand the application range with technological progress and become mainstream products for grinding.
