[0002] Microcrystals refer to the specific structure of abrasive grains. Each individual abrasive grain combines with a large number of small alumina particles during the manufacturing process. Due to the fine boundaries between the alumina particles within the grain, the grains form what is known as a microcrystalline structure. Silicon carbide composite ceramic microcrystalline abrasives are a high-performance abrasive widely used in coated abrasives and other grinding applications. The microcrystalline structure provides a larger contact area and a more uniform grinding effect, reducing heat generation during the grinding process. The combination of microcrystalline silicon carbide with other ceramic materials enhances the toughness and strength of the material.

[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] like Figures 1 to 5 As shown, an embodiment of the present invention provides a coating abrasive for silicon carbide composite ceramic microcrystalline abrasive, comprising a substrate layer 1, an antistatic layer 3, a strength layer 5, and a fixing component 11.

[0025] The spraying method ensures a strong bond and reduces static electricity conduction, thus preventing a large amount of debris from adsorbing onto the coated abrasive surface.

[0030] The abrasive bumps 9 and chip removal grooves 10 allow for the discharge of grinding waste while grinding the object, preventing clogging of the coated abrasive.

[0031] like Figure 1 and Figure 5 As shown, in a preferred embodiment of the present invention, the upper end of the substrate layer 1 is provided with a storage groove 1106 for storing the elastic band 1101 and the sealing band 1104, and the sealing band 1104 is movably connected to the substrate layer 1 through the storage groove 1106.
