Description

Technical Field

[0001] The utility model relates to the technical field of boron nitride grinding discs, in particular to a cubic boron nitride grinding disc provided with a self-cleaning structure. Background Art

[0002] Cubic boron nitride is a new type of artificially synthesized material. Due to its excellent grinding performance, it is not only capable of processing difficult-to-grind materials and improving productivity, but also conducive to strictly controlling the shape and dimensional accuracy of workpieces, and can effectively improve the grinding quality of workpieces, significantly improve the surface integrity of workpieces after grinding, thereby improving the fatigue strength of parts, extending service life, and increasing reliability. In addition, the production process of cubic boron nitride abrasives is better than that of ordinary abrasives in terms of energy consumption and environmental pollution. Therefore, cubic boron nitride grinding tools have been widely used in the mechanical processing industry. According to the announcement number: CN220260682U, a cubic boron nitride grinding disc for grinding sliding blades is disclosed, which relates to the field of grinding. A cubic boron nitride grinding disc for grinding a sliding piece comprises: a mounting disc body; a plurality of mounting grooves are circumferentially provided on the mounting disc body; a rubber pad fixedly connected to the inner wall of the mounting groove; compared with the grinding disc arranged as a whole in the prior art, when the grinding disc is damaged, there is no need to replace the grinding disc as a whole, and only the damaged single cubic boron nitride grinding block needs to be replaced, thereby effectively reducing the processing cost; by setting a certain distance between every two cubic boron nitride grinding blocks, a discharge groove can be formed between every two cubic boron nitride grinding blocks; when the cubic boron nitride grinding blocks grind the workpiece, the debris generated by the grinding will leave the workpiece surface through the discharge groove under the action of centrifugation, thereby avoiding the debris from causing wear to the workpiece surface and ensuring the quality of the workpiece grinding; however, the above technology still has some defects, such as the existing grinding disc is not designed with a cleaning structure, and after use, a large amount of debris will adhere to the bottom end of the grinding disc due to rapid rotation, which will cause the next use effect to be poor, and the practicality is poor, and improvement is needed.
