The manufacturer of diamond segment for granite cutting tells you that in the cutting head manufacturing skills, the selection of the cutting head carcass material and the hot pressing process are the more critical hubs. Co-based and bronze-based alloys are widely selected as raw materials for the carcass, but they cannot achieve a good balance between manufacturing cost and performance.

The diamond segment for granite cutting manufacturer tells you that the manufacturing process of the diamond saw blade head can be described as the sintering process of metal powder under certain pressure. It is a kind of powder metallurgy process: the well-proportioned metal powder is at high temperature (800-1000℃). ) And certain pressure (180-250Kgf/cm2), through a series of physical and chemical impregnation, such as diffusion, welding, compounding, and recrystallization between powder particles, a sintered body with certain shape and machine function is formed, which is the cutter head .
There are also strict requirements on the foundation of the raw material of the saw blade head carcass:
1. The manufacturer of diamond segment for granite cutting tells you that the sintered body should have excellent attack performance and appropriate hardness to ensure the formation of brilliant machine meshing for the wrapped diamond and moderate abrasion resistance to the rock;
2. It can complete the powder metallurgy process that satisfies the above-mentioned performance requirements at a lower sintering temperature (unusually not more than 950°C) and a shorter holding time (unusually not more than 5 minutes), so as to slow down the diamond single crystal Deterioration trend;
3. The alloy components in the matrix alloy can brilliantly infiltrate the diamond single crystal, and through the intervening trace elements, the alloy components and the diamond can be bred to produce chemical bonding and impregnation, which further improves the means of coaxing diamonds.
The manufacturer of diamond segment for granite cutting tells you that the powder metallurgy method can make the raw material of the carcass have a structure similar to that of an ordinary alloy to achieve alloying. There are many kinds of phases in the alloy structure. Among the components with similar electrochemical properties and atomic radii, the alloy is biased towards the eugenic solid solution phase. The manufacturer of diamond segment for granite cutting tells you that because the crystal lattice is deformed in the natural process of the solid solution phase, the resistance to the movement of the dislocation of the crystal lattice is increased, so that the strength and hardness of the raw material are improved, that is, the solid solution strengthening occurs. Dyeing, therefore, the solid solution phase becomes the most basic component phase that requires higher raw materials for comprehensive machine functions. It can be said that the formation of the solid solution phase of the carcass alloy is one of the keys to achieving the high performance of the carcass raw material.
