Message:SG grinding wheel is especially suitable for grinding aerospace alloy, tool steel, hardened workpiece, hard chromium, hard cast iron, etc. Due to the high price of SG abrasive, SG can be mixed with white corundum (or other corundum abrasive) in a certain proportion according to the grinding requirements of different occasions to make the grinding wheel, so as to achieve the best combination of grinding effect and grinding wheel cost. The grain size of abrasive is used to indicate the size of abrasive particles. The selection is mainly based on the surface roughness required to process the workpiece, and other factors (such as grinding efficiency, village material characteristics, etc.) should also be considered. Manufacturing process of SG abrasive In a general sense, SG abrasive manufacturing process is to first mix aluminum monohydrate (Al2O3·H2O) powder and water into a suspension, in which a colloidal solvent (such as nitric acid or hydrochloric acid solution) is added to make it a stable aqueous sol or colloidal suspension. Then, a modified agent (usually a metal oxide or its predecessor, such as Mg (NO3) 2, etc.) is added to gelate the sol. The formed condensate will be dried and solidified, and then broken (or cut) into the required shape and size of particles, which will be turned into abrasive after calcination. SG abrasive can be used to make all kinds of consolidation and coating grinding tools, and their performance is obviously better than that of similar common corundum grinding machines. Generally speaking, SG abrasive materials have a high manufacturing cost, so it is commonly used in industry to make grinding machines mixed with common abrasive materials.
