Tips for cutting discs


Grinding wheel cutting discs are an indispensable part of the abrasives industry. In grinding, abrasives or abrasives are often used as grinding tools to machine the parts to be processed to meet certain technical requirements. Among them, abrasive products are mainly divided into two categories: corundum abrasives and silicon carbide abrasives. Specifically, there are basically the following types:

One: corundum abrasive

1. Brown corundum abrasive, the main component is Al2O3, with medium hardness, high toughness, sharp particles, relatively low price, suitable for processing metals with high tensile strength. Both microcrystalline corundum abrasives and black corundum abrasives are derived species.

2. The hardness of white corundum abrasive is slightly higher than that of brown corundum, but its toughness is poor. It is easy to cut into the workpiece during grinding, has good self-sharpening, low heat generation, strong grinding ability and high efficiency.The chromium corundum abrasive is its derivative species.

3. Single crystal corundum abrasive, its particles are composed of a single crystal, and have a good multi-edge cutting edge, high hardness and toughness, strong grinding ability, low grinding heat, the disadvantage is that the production cost is high, and the output Lower, so the price is higher. Zirconium corundum abrasive is also a crystalline compound, with slightly lower hardness, finer crystal size, and good wear resistance.


Two: Silicon carbide abrasive

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 grains, good thermal conductivity, and wear resistance.Strong performance, more suitable for processing hard and brittle metal and non-metal products.
