A basic industry in the abrasives industry has always played an important role in machining. As far as abrasive abrasives are concerned, there are still needs to be improved and broken in the following three aspects.

First, the improvement of the physical structure of the abrasive tool; if the number of abrasive grains per unit time is increased, the average length of the grinding is increased, and the grinding contact surface is increased, these all change the amount of grinding time per unit time, effectively improving effectiveness.

Second, the application of superhard abrasives mainly refers to the use of superhard materials such as metal powder, metal oxide or CBN as fillers, and the use of resin, ceramic or metal bond as abrasives. At present, the polishing sheet has been widely recognized for its high precision and high efficiency grinding effect by superhard abrasives.

Third, new abrasive tools have emerged, such as micron-sized polycrystalline ceramic microcrystalline abrasives, fine diamond abrasive spherical shell abrasives, and superfine polishing polyester film tapes. These new abrasives have their own characteristics, and the polishing sheet gives the advantages of grinding and processing to the fullest.

Throughout the development of the grinding field, the future grinding process will put forward higher requirements for abrasive grinding tools. Judging from the current situation, superhard products just meet these new grinding needs. For example, CBN abrasive has good thermal stability, high hardness, and good wear resistance. Therefore, the grinding machine has high line speed, high grinding efficiency and high life of grinding tools. It is especially suitable for processing high-speed steel and bearing steel. Black metal materials such as stainless steel and cold-excited cast iron.

In addition, it meets various needs of ceramic bond grinding wheels, high-speed grinding wheels for atmospheric holes, and different abrasive grinding wheels, polishing sheets, diamond saw blades, etc., which will be expanded with the advancement of technology and become the mainstream products for grinding.thin abrasive cutting disc for metal
