For the stainless steel
high quality cutting disc supplier we use, there are many kinds of them. For example, there are three kinds of brown fused alumina, white corundum, and silicon carbide. Among these materials, silicon carbide is the hardest, and brown fused alumina is the hardest. Weak, so, today, Henan abrasives manufacturers to give you a general introduction, what are the characteristics of stainless steel special cutting sheet materials?
1. White corundum: It is made of industrial alumina powder as raw material, cooled in the arc by high-temperature smelting above 2000 degrees, and then pulverized and shaped, magnetically selected to remove iron, sieved into various particle sizes, and its texture is dense and high in hardness. It is formed into a sharp angle and is suitable for the manufacture of ceramics, resin-bonded abrasives, as well as grinding, polishing, sandblasting, precision casting (special corundum for precision casting), etc., and can also be used to manufacture advanced refractory materials.
2, brown corundum: using bauxite, coke (anthracite) as the main raw material, smelting in the electric arc furnace by high temperature, using it to make the grinding tool, suitable for grinding high tensile metal, such as various General steel, malleable iron, hard bronze, etc., can also be made of advanced refractory materials. It has high purity, good crystallization, strong fluidity, low coefficient of linear expansion and corrosion resistance.
3, silicon carbide: quartz sand, petroleum coke (or coal coke), wood chips as raw materials through the resistance furnace high-temperature smelting. In contemporary C, N, B and other non-oxide high-tech refractory raw materials, silicon carbide for applications The most extensive and economical one. It can be called gold steel sand or refractory sand.
What is the abrasive grain size of the grinding wheel?
For the abrasives, we learned from the previous introduction that the abrasive is a sharp and hard material to grind the surface of the softer material. The grain size of the abrasive wheel refers to the size of the abrasive particles. And micro-powder two kinds. So, what is the abrasive grain size of the grinding wheel? I don't know if it doesn't matter, the following grinding wheel ultra-thin manufacturers come to introduce you.
The abrasive grain size of the
fiber cutting disc Chinese supplier is mainly related to the surface roughness and productivity of the machined surface. When rough grinding, the grinding allowance is large, and the required surface roughness value is large. The coarser abrasive grains should be used. Because the abrasive grains are thick and the pores are large, The grinding depth can be large, the grinding wheel is not easy to block and heat. When grinding, the margin is small, the roughness value is required to be low, and finer abrasive grains can be selected. Generally speaking, the finer the abrasive grains, the surface roughness is ground. The better and the range of use of different sizes of grinding wheels are also different.
Moreover, for the choice of grinding wheel hardness, we should also pay attention to the processing of soft metal, in order to prevent the abrasive from falling off prematurely, the hard grinding wheel is used. When the hard metal is processed, in order to timely remove the blunt abrasive particles, the exposed Sharp abrasive edges of the new abrasive particles (ie self-sharp), the choice of soft grinding wheel.
