Diamond Segment

1. Diamond cutter head is the main body of diamond saw blade. The blade of the diamond saw blade is composed of diamond and carcass bonding agent. Diamond is a super hard material, which acts as a cutting edge, and the carcass bonding agent plays a role of fixing diamond. Composition, different composition is called formula, according to different uses, formula and diamond are different.

2. In the tip manufacturing technique, the selection of the tip carcass raw materials and the hot pressing process are the key pivots. Co-based and bronze-based alloy systems are widely selected as raw materials for the carcass, but they cannot do a good job in terms of manufacturing cost and performance. Through the level analysis, Fe-Ni-Cu-W series alloy was proposed as the raw material of the cutter head carcass. Through trial and application, the ideal manufacturing cost and function were achieved.

The manufacturing process of diamond saw blades can be described as the sintering process of metal powder under certain pressure. It is a process of powder metallurgy: the symmetrical metal powder is under high temperature (800-1000 ℃) and under certain pressure (180- 250Kgf / cm2), through a series of physical and chemical impregnation of powder particles by diffusion, fusion welding, compounding, recrystallization, etc., to form a sintered body with a certain shape and mechanical function, that is, the cutter head.
