2.Metal grinding disc

Its material composition: can be divided into two kinds, sintering, electroplating.Sintering - separable copper and iron.The copper base is made of copper mainly + diamond + other metal materials (silver powder, nickel powder, tin powder, iron powder, etc.) at high temperature.The iron base is made of iron mainly + diamond + other metal materials (silver powder, nickel powder, tin powder, iron powder, etc.).

Electroplating - can be divided into chemical plating, vacuum plating.Copper base - good sharpness, diamond sharp edge, high efficiency.Iron base - good wear resistance, sharpness and slow edge.

Good grinding discs are mainly related to diamonds (diamond grade, bonding agent, manufacturing process).Yuanxu metal grinding sheet T type, the garden type is used for stone, the combination of concrete sharpness and wear resistance is good, and the variety is economical.
