Grinding wheel is an indispensable tool for cutting metal and non-metal materials. It is composed of a matrix (such as steel) and a wear-resistant layer such as cemented carbide or diamond embedded in its surface. According to their different uses, they are divided into two types: ordinary grinding wheels and special grinding wheels made of superhard materials.
Ordinary grinding wheel:
For grinding workpieces such as cast iron, cast steel and carbon structural steel. It can also be used for grinding heat-resistant alloys, stainless steel and various non-ferrous metals after quenching and tempering, as well as grinding parts with special surface processing.
Special grinders made of superhard materials:
Has high abrasion and impact resistance. Mainly used for cutting high hardness materials. In addition, there are super hard coating inserts for high-speed milling cutters and diamond polycrystalline cubic boron nitride composite sheets for drill bits. Among the tools used in industry, except for high-speed rotating tools. There is also a low-speed rotating tool used on stationary machine tools called a “saw blade”. A saw blade generally consists of several saw blades to form a working unit. In order to improve the life of the saw blade and reduce the production cost, the number of teeth in the “serrated” structure gradually increases and tends to be densely arranged. The greater the number of teeth in this serrated structure, the more beneficial it is to improve cutting performance and reduce costs. However, when the number of teeth exceeds a certain limit, the cutting performance will be reduced or even cracks will occur, which will shorten the service life or even fail.
