What is the impact of the hardness of the 4 1/2 super thin cutting disc wheel on the machining? In general, it has the following effects:
The hardness of the cutting wheel has a significant effect on the quality of the machined surface and the grinding efficiency. The hardness of the grinding wheel is high, the abrasive grains are not easily peeled off, and the contour of the abrasive cutting edge is easily maintained, so that the workpiece has low roughness and high precision. However, if it is too hard, the blunt abrasive grains still remain on the surface of the grinding wheel, which not only reduces the grinding efficiency, but also increases the frictional extrusion on the surface of the workpiece due to the passivated abrasive grains, grinding force and grinding. The heat is significantly increased to increase the surface roughness of the workpiece, and it is also prone to defects such as burn cracks.
