1.Sintered diamond saw blades are divided into two parts, namely, cold pressing sintering and hot pressing sintering.
2.Welding diamond saw blade: two kinds of brazing and laser welding. The brazing is welded together by high temperature melting medium, such as high frequency induction brazing saw blade, vacuum brazing saw blade, and laser welding through high temperature laser beam to melt the edge of the tool head and the matrix into metallurgical bonding.
3.Electroplating (brazing) diamond saw blade: the blade powder is adhered to the substrate by electroplating. Since 2012, the state has gradually cancelled the production of electroplated diamond products, mainly because of the serious pollution.
