Over the past 18 years, TAOANG products range from raw material bauxite to processing follow-up products brown fused alumina, finishing white fused alumina and dense fused alumina, bubble alumina, and fused alumina micro powder. The production process is fully controlled to achieve control of product quality and price.
SG Abrasive(ceramic abrasive grain) is a special crystallized gel system sintered with a revolutionary new generation of alumina abrasives with high hardness, good toughness and strong sharpness. Compared with ordinary corundum abrasives, SG has the advantages of high wear ratio, strong shape retention, good surface processing quality, small wheel dressing and high grinding efficiency.
SG grinding wheels are particularly suitable for grinding aerospace alloys, tool steels, hardened workpieces, hard chrome, hard cast iron, etc. Because SG abrasives are more expensive, SG can usually be mixed with white corundum (or other corundum abrasives) in a certain proportion according to the grinding requirements of different occasions to achieve the best combination of grinding effect and grinding wheel cost. Abrasive Particle Size Particle size is used to indicate the size of the abrasive grain geometry. The choice is based on the surface roughness required to machine the workpiece, as well as other factors (such as grinding efficiency, village material characteristics, etc.). In the case of external round grinding, the common particle size and surface roughness have the following general relationship: < particle size 36-46; 54-60; 70-80; 90-100; roughness coarse-grained Abrasives are suitable for grinding: softer materials, high elongation and similar materials such as soft iron and non-ferrous metals. When the feed rate is large and the grinding efficiency is high, the surface roughness is not high. Grinding where the contact surface is large. Fine-grained abrasives are suitable for grinding: high hardness and similar high-carbon tool steels, metal materials such as hard alloys and brittle materials such as glass. When the surface roughness and accuracy are high. Grinding where the contact surface is small. When the workpiece radius or the degree of separation is small. The hardness of the grinding wheel refers to the degree of bonding between the abrasives. The amount of bonding in the grinding wheel determines the hardness of the grinding wheel. The user needs to flexibly select the hardness of the grinding wheel according to the specific grinding requirements (such as the amount of feed, roughness, material).
