Grinding wheels used on grinding machines have different specifications, different sizes, different thicknesses, and different particle sizes. This is mainly based on the customer’s requirements to select the particles of the grinding wheel. In addition, the grinding wheel should be selected according to the material of the workpiece ground by the customer. The following small series will give you a brief introduction to the classification of grinding wheels.
The choice of the particle size of the grinding wheel
High productivity when grinding with coarse-grained grinding wheels. However, the surface of the ground workpiece is rough. When grinding with a fine-grained grinding wheel. The surface roughness of the ground workpiece is better, but the productivity is lower. On the premise of meeting the roughness requirements, the coarse-grained grinding wheel should be selected as much as possible. To ensure high grinding efficiency. Generally, a coarse-grained grinding wheel is used for rough grinding, and a fine-grained grinding wheel is used for fine grinding.
The most commonly used abrasives are brown corundum (A) and white corundum (WA). This is followed by black silicon carbide (C) and green silicon carbide (GC). The other commonly used ones are chrome corundum (PA), single crystal corundum (SA), microcrystalline corundum (MA), and zirconium corundum (ZA).
