Effect of grinding amount on surface roughness

1) The higher the speed of the cutting disc, the more the number of abrasive grains passing through the surface to be polished per unit time, and the smaller the roughness value of the surface of the workpiece. At the same time, the higher the speed of the low price disc for metal, the higher the speed of plastic deformation of the surface metal is then the cutting speed, the workpiece material is not too deformed, so that the plastic deformation of the surface metal is reduced, and the roughness value of the grinding surface is also reduced.

2) The influence of the workpiece speed on the surface roughness is just the opposite of the influence of the cutting disc speed. When the workpiece speed is increased, the number of abrasive grains passing through the surface to be polished per unit time is reduced, and the surface roughness value is increased.

3) The longitudinal feed of the cutting disc is reduced, the number of times each part of the surface of the workpiece is repeatedly ground by the cutting disc is increased, and the roughness value of the surface to be ground is reduced. Abrasive grinding machine grinding WeChat professionalism is the strongest!

4) When the grinding depth is increased, the plastic deformation of the surface layer will increase, and the roughness value of the surface to be ground will also increase.
