1. Sintered diamond saw blade: divided into cold pressing sintering and hot pressing sintering, pressed and sintered.
2. Welding diamond saw blades: divided into two types: brazing and laser welding. Brazing is to weld the cutter head and the base through a high-temperature melting medium, such as high-frequency induction brazing saw blades, vacuum brazing saw blades, etc.; laser welding The contact edge of the cutter head and the substrate is melted by a high-temperature laser beam to form a metallurgical bond.
3. Electroplating (brazed) diamond saw blade: the blade powder is attached to the substrate by electroplating. Since 2012, the country has gradually eliminated the production of electroplated diamond products, mainly because of serious pollution.
