The grinding wheel has high temperature and the heat is dominant, so it is very important for the role of the cutting fluid. The use of cutting fluid can reduce the temperature of the grinding zone, reduce burns, wash away sand and chips, so as not to scratch the workpiece, thus reducing the surface roughness value.

The heat carrying capacity of the wheel is required to be higher for the higher temperatures generated due to grinding carried out at high speeds. If the porosity is kept higher for this purpose, when the grinding wheel rotates at a high speed, there is a possibility that the strength of the grinding wheel may be less.

In high-precision grinding machines (most cylindrical and surface grinders), the final grinding stages are usually set up so that they remove about 200 nm (less than 1/10000 in) per pass – this generates so little heat that even with no coolant, the temperature rise is negligible. Types of Grinding Machines.
