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.
Grinding Machine Definition: A grinding machine is a production machine tool used in the manufacturing industry in which the grinding wheel is attached in the tool post and the workpiece is fixed to the work table and when the operation starts it removes the unwanted material to get the desired surface finish, correct size, and accurate shape of the workpiece.
To machine parts on CNC grinding machines, a porous grinding wheel with high circumferential speed is brought into contact with the part and thereby removes chips from the part surface. Grinding is a cutting process using geometrically undefined cutting edges. Heat is generated due to the friction between the grinding wheel and the part as well ...
