Which abrasive products are mainly divided into corundum abrasive and silicon carbide abrasive two categories, specifically, there are basically the following:

    1. Corundum abrasive, the main component is Al2O3, with a moderate hardness, toughness, grain Fengrui, the price is relatively low, suitable for processing high tensile strength of the metal. Microcrystalline corundum abrasive and corundum abrasives are all derived varieties.

    2. White corundum abrasive, the hardness is slightly higher than the corundum, but the toughness is poor, easy to cut into the workpiece when grinding, self-sharpening, heat less, grinding ability, high efficiency. Chrome corundum abrasive is its derived varieties.

    3. Single crystal corundum abrasive, the particles are composed of a single crystal, and has a good multi-edge cutting edge, high hardness and toughness, grinding ability, grinding less heat, the disadvantage is the higher production costs, Lower, so the price is relatively high. Zirconia corundum abrasive is also a crystal compound, slightly lower hardness, crystal size is smaller, good wear resistance.

    4. Black silicon carbide abrasive, green silicon carbide abrasive, cubic silicon carbide abrasive, cerium carbide abrasive, etc., are silicon carbide abrasive, the main component is silicon carbide SiC, high hardness, brittle, abrasive sharp, good thermal conductivity, Wear resistance is strong, more suitable for processing hard and brittle metal and non-metallic products.

    Abrasives usually include two types of ordinary abrasive and superhard materials.

    1. Ordinary abrasive refers to the abrasive made of ordinary abrasive. According to the combination of abrasive is divided into consolidated abrasive and coated abrasive, and according to the different binding agent can be divided into ceramic abrasive, resin abrasive, rubber abrasive, magnesite abrasive series.

    2. Superhard material abrasive, mainly metal powder, metal oxide or CBN and other superhard materials as a filler, can also be properly added to ordinary abrasives (such as Al2O3, SiC, etc.) to resin binder or ceramic binder or metal Binding agent made of abrasive.
