The grinding disc itself is mutually adjusted with the workpiece during the grinding process, and the geometric accuracy of the grinding disc itself is transcribed onto the workpiece to a certain extent. Therefore, it is required that the machining surface of the grinding disc has high geometric accuracy. The main requirements for grinding discs are:
(1) The hardness of the material is generally lower than that of the workpiece material, the organization is uniform and dense, without impurities, foreign objects, cracks and defects, and has a certain degree of abrasive embedding and immersion.
(2) Reasonable structure, with good rigidity, accuracy retention, and wear resistance. Its working surface should have high geometric accuracy.
(3) Good chip removal and heat dissipation
