[0002] Resin grinding discs are resin-made grinding wheels with a certain degree of elasticity and good self-sharpening properties. They are widely used in processes such as rough grinding, parting, and free-cutting. Patent number CN202220999398.4, titled "Resin-coated Grinding Disc," incorporates a continuous or discontinuous ring-shaped metal welded cutter head within the resin abrasive layer to improve heat resistance and wear resistance, ensuring that workpieces are fed without chipping and a high-quality, smooth finish. This effectively increases the service life of the resin grinding disc by 32% to 44%.
