PCD circular saw blade is a cutting tool, widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone, ceramics, etc. Diamond saw blades are mainly composed of two parts; the base body and the cutter head. The substrate is the main supporting part of the bonded cutter head, while the cutter head is the part that cuts during use. The cutter head will be continuously consumed during use, but the substrate will not. The reason why the cutter head can cut The role of diamond is because it contains diamond, which is currently the hardest substance, and it rubs and cuts the processed object in the cutter head. The diamond particles are wrapped in metal inside the cutter head.
1. Sintered diamond saw blade: It is divided into two types: cold press sintering and hot press sintering, which are formed by pressing and sintering.
2. Welding diamond saw blades: There are two types: brazing and laser welding. Brazing is to weld the cutter head and the substrate together through high-temperature melting media, such as high-frequency induction brazing saw blades, vacuum brazing saw blades, etc.; laser welding The contact edge between the tool tip and the substrate is melted by a high-temperature laser beam to form a metallurgical bond.
3. Electroplating (brazing) diamond saw blade: the blade powder is attached to the substrate by electroplating. Since 2012, the country has gradually canceled the production of electroplated diamond products, mainly because of the serious pollution.
