Description

Technical Field

[0001] The utility model relates to the technical field of diamond grinding wheels, and more specifically, to a high-toughness diamond grinding wheel. Background Art

[0002] In the existing technology, high-toughness diamond grinding wheels face some challenges and limitations during the grinding process. First, a large amount of heat is generated during the friction between the diamond layer and the cemented carbide substrate, which will cause the temperature of the grinding wheel to rise, thereby affecting its performance and life. Due to the poor heat dissipation effect in the existing technology, this heating phenomenon may accelerate the wear of the diamond layer and reduce the service life of the grinding wheel. At the same time, due to insufficient elastic deformation capacity, the grinding wheel is prone to cracking when subjected to greater pressure or impact, which further limits its scope of application.

[0003] Secondly, the grinding wheel will produce different degrees of wear during long-term use and needs to be replaced regularly to ensure the quality and efficiency of grinding. However, the installation and disassembly operations of the grinding wheel in the prior art are usually cumbersome and require more time and effort, which makes replacing the grinding wheel a time-consuming and laborious process, especially when it is necessary to replace grinding wheels of different mesh sizes according to different process requirements. This cumbersome operation not only reduces production efficiency, but may also cause production interruptions, which has an adverse effect on overall work efficiency.

[0004] In addition, although some mechanisms in the prior art can achieve rapid replacement of grinding wheels, their structures are relatively simple, which easily leads to a weak connection. This unstable connection problem may affect the normal operation of the grinding wheel, resulting in a decrease in grinding quality and even potential safety hazards such as the grinding wheel falling off. Therefore, a high-toughness diamond grinding wheel with a more stable structure and easier operation is needed to meet the needs of practical applications and improve production efficiency and safety.
