Selection of grinding wheel
A variety of grinding wheel types, and a variety of shapes and sizes, according to the grinding wheel abrasive, binder materials and manufacturing processes are different, each kind of grinding wheel has a certain scope of application. If you choose improper will directly affect the processing accuracy, surface roughness and production efficiency. Therefore, grinding, must be selected according to the specific circumstances of the appropriate wheel. So how should the correct choice of grinding wheel? Grinding for the commonly used grinding wheel summary, so that we clearly choose the wheel in vain.
Selection of ordinary grinding wheel
(1) Abrasive selection Abrasive selection depends mainly on the workpiece material and heat treatment methods.
A. Grinding tensile strength of high material, the choice of toughness of the abrasive.
B. Low hardness, elongation of large materials, the use of more brittle abrasive.
C. High hardness of the material, the choice of higher hardness of the abrasive.
D. Use abrasives that are less susceptible to chemical reactions.
The most commonly used abrasives are corundum (A) and white corundum (WA), followed by black silicon carbide (C) and green silicon carbide (GC), the rest are commonly used chrome corundum (PA), monocrystalline corundum (SA) , Microcrystalline corundum (MA), zirconia corundum (ZA).
