Grinding wheel type

First, the choice of an ordinary wheel. Abrasive Abrasive choice depends largely on the choice of the workpiece material and heat treatment method. a. grinding high tensile strength of the material, the selection of toughness abrasive. b. grinding low hardness, elongation of the material, the selection of more brittle abrasive. c. grinding material with high hardness, the selection of higher hardness abrasives. d.  polycrystalline diamond  can not easily be processed abrasive chemical reaction. The most commonly used abrasives are corundum (A) and corundum (WA), followed by the black silicon carbide (C) and green silicon carbide (GC), and the rest of the commonly used chromium corundum (PA), a single crystal corundum (SA) , microcrystalline corundum (MA), zirconium corundum (ZA). Corundum grinding wheel: corundum hardness, toughness, suitable for grinding high tensile strength metals such as carbon steel, alloy steel, malleable iron and hard bronze, etc. The abrasive grinding performance, adaptability, commonly used in the removal of coarse large margin, cheap, can be widely used. Corundum grinding wheel: slightly higher than the hardness of corundum corundum, corundum toughness lower than in grinding, abrasive shatter easily, so grinding heat a small, suitable for  Synthetic diamond grinding hardened steel, high carbon steel, high-speed steel and thin-walled parts with grinding wheel, high cost than corundum. Black silicon carbide grinding wheel: black silicon carbide is brittle and sharp, high hardness than corundum, suitable for grinding lower mechanical strength of the material, such as cast iron, brass, aluminum and refractories. Green silicon carbide abrasive grinding : Green silicon carbide high hardness brittle than black, abrasive sharp, good thermal conductivity, suitable for grinding carbide, optical glass, ceramics and other brittle materials. Chrome corundum grinding wheel: suitable for grinding tools, measuring tools, instruments, thread and other surface processing, high quality requirements of the workpiece. Monocrystalline corundum grinding wheel: suitable for grinding stainless steel, high vanadium high speed steel toughness, high hardness materials and deformation of the workpiece burn. Microcrystalline corundum grinding wheel: suitable for grinding stainless steel, bearing steel and special cast iron, etc., for forming mill, cut grinding, mirror grinding. Corundum grinding wheel: Olympic Di body for grinding stainless steel, titanium, heat-resistant alloys, particularly suitable for heavy-duty grinding. (2) size depends on the choice of surface roughness by grinding the workpiece and grinding efficiency. Particle size refers to the size of the abrasive particles, the size of a grain size number is expressed. Grinding wheel with a coarse-grained, high production efficiency, but the grind of the workpiece surface is rough; using fine-grained grinding wheel, grind the surface roughness is better, and lower productivity. Meet the requirements under the premise roughness, should try to use coarse-grained grinding wheel in order to ensure a high grinding efficiency. Generally when the choice of coarse grained grinding wheel, grinding wheel when fine-grained selection.
