Common types of abrasive

Need to use the mold with abrasive, abrasive and share with everyone today, the main species, which mainly include mainly corundum, white corundum, silicon carbide and green silicon carbide.
Corundum high toughness, suitable for grinding carbon steel, alloy steel, malleable iron and hard bronze high tensile strength of the material. Corundum has a higher hardness than corundum, cutting performance is better, for hardened steel, high carbon steel, high speed tool materials such as grinding processes.
Black silicon carbide, high hardness, brittle and sharp, suitable for grinding, cutting, low tensile strength of the material, such as: cast iron, glass, ceramics, stone, refractory material and so on.
Darker green silicon carbide high purity silicon silicide. Suitable for grinding carbide, optical glass, precious stones, agate and other hard and brittle materials.
Granularity:
The choice of abrasive particle size depends on the surface of the workpiece machining accuracy and productivity requirements. Coarse-grained and medium-grained abrasive for roughing and semi-finishing, and fine-grained abrasive, it applies to finishing and super finishing. Physical and mechanical properties are grinding department also factors that determine particle size, low hardness, ductility and toughness of the material is appropriate to coarse-grained abrasive machining, high hardness brittle materials appropriate to fine-grained abrasive.
Organization:
Organization refers to the abrasive grinding composition of the abrasive, bond and porosity volume ratio between the three. Less abrasive, large porosity called loose tissue, otherwise tightly organized.
Tightly organized abrasive, should be used for grinding, profile grinding and processing remain small while the surface finish of the workpiece.
Medium organizations are widely used in the general allowance abrasive grinding work piece.
Loose abrasive for flat organization, such as the inner circle of a large contact surface of the grinding and grinding expansion sensitive soft material of the workpiece and the workpiece.
Hardness:
Abrasive abrasive surface is fixed to the strength of the binding agent. Or under external force, the degree of difficulty shedding, known abrasive hardness.
