What is an abrasive tool?
2022/12/7
Abrasive abrasives are the general name of abrasives and abrasives, including abrasive products and abrasive products. Abrasive abrasives are known as industrial teeth. When grinding, abrasive or abrasive tools are often used as grinding tools to machine parts to meet certain technical requirements.
Commonly used abrasive mills include cutting blades and grinding wheels, louver plates, quick-change grinding blades, grinding rolls, bonded grinding wheels, Chiba grinding rings and sandpaper grinding rings, unbonded Chiba grinding wheels, Chiba grinding wheels, sandpaper rolls and velvet rolls, and tungsten steel rotary files.
Among them, abrasive products are mainly divided into corundum abrasive and silicon carbide abrasive. Specifically, there are basically the following types:
1. Brown corundum abrasive, mainly composed of Al2O3, has moderate hardness, high toughness, sharp particles and relatively low price, and is suitable for processing metals with high tensile strength. Microcrystalline corundum abrasive and black corundum abrasive are its derivative varieties.
2. The hardness of white corundum abrasive is slightly higher than that of brown corundum, but its toughness is poor, and it is easy to cut into the workpiece during grinding, with good self-sharpening, small calorific value, strong grinding ability and high efficiency. Chrome corundum abrasive is its derivative.
3. Single crystal corundum abrasive, whose particles are composed of single crystal, has good multi-edge cutting edge, high hardness and toughness, strong grinding ability, and less grinding heat, has the disadvantages of high production cost and low output, so the price is relatively high. Zirconium corundum abrasive is also a crystal compound with slightly lower hardness, finer crystal size and good wear resistance.
4. Black silicon carbide abrasives, green silicon carbide abrasives, cubic silicon carbide abrasives, cerium silicon carbide abrasives, etc. belong to silicon carbide abrasives. The main component is silicon carbide SiC, which has high hardness, high brittleness, sharp abrasive particles, good thermal conductivity and strong wear resistance, and is more suitable for processing hard and brittle metal and nonmetal products.
