[0002] A ceramic grinding wheel is a type of abrasive tool, mainly composed of three parts: abrasive, bonding agent, and pores. The bonding agent is made of ceramic material, the abrasive is the cutting part of the grinding wheel, responsible for removing material from the surface of the workpiece; the role of the bonding agent is to bind the abrasive particles together, giving the grinding wheel a certain shape and strength; and the pores help with chip removal and heat dissipation.

[0003] For example, Chinese patent CN220241176U discloses a ceramic grinding wheel, including a fixed disc, a first grinding wheel disc on one side of the fixed disc, and a movable and adjustable second grinding wheel disc inside the first grinding wheel disc. The first and second grinding wheel discs have different roughness levels. A telescopic adjustment mechanism is provided between the second grinding wheel disc and the fixed disc. Both the first and second grinding wheel discs are provided with annular grinding wheels, and the inner diameter of the first grinding wheel disc is larger than the outer diameter of the second grinding wheel disc. This utility model, by providing a movable and adjustable second grinding wheel disc inside the first grinding wheel disc and by using the first and second grinding wheel discs with different roughness levels, allows for the adjustment of grinding wheel discs with different roughness levels as needed for grinding, which is beneficial to improving grinding efficiency. Moreover, the adjustment is convenient and quick, improving the flexibility of use.
