Selection of abrasives for grinding wheels

The grinding wheel plays the role of a tool for cutting the workpiece during grinding, so the selection of the grinding wheel will directly affect the machining accuracy, surface roughness of the grinding workpiece and the service life of the grinding wheel. Generally, the abrasive, particle size, hardness and the combination of All and the shape of the grinding wheel should be selected according to factors such as the material, mechanical properties, machining accuracy, surface roughness and shape of the workpiece to be ground.

Selection of abrasive grain size of the grinding wheel .The abrasive grain size of the grinding wheel indicates the size of the cheek particles; the number of the particle size indicates the number of holes in the sieve'in area. The larger the particle size number, the smaller the gluing particles.The number of particle sizes indicates the number of holes in the area of the sieve. The larger the particle size number, the smaller the gluing particles.

The correct selection of the abrasive grain size will directly affect the surface quality of the tooth profile of the blade of the blade saw blade. The selection principle of the grinding wheel particle size of the sharpening saw blade milling cutter is as follows:

1) When grinding workpiece materials with low hardness or good toughness, the abrasive particles of the grinding wheel are easily blocked, which burns the grinding surface. Therefore, the abrasive particles are large, that is, the particle size number is small.

2) The finer the roughness of the workpiece surface, the smaller the grinding wheel particles, that is, the larger the particle size number. If the rough and fine grinding are sharpened on the same grinding wheel, a medium-sized grinding wheel should be used
