Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheel production, and specifically refers to a grinding wheel with an easily replaceable grinding wheel layer. Background Art

[0002] A grinding wheel is a tool used for grinding processing, usually composed of abrasive, binder, and pores. During the manufacturing process of the grinding wheel, abrasive particles are mixed with the binder, and then through processes such as pressing and sintering, a grinding tool with a certain shape is formed. The grinding wheel is mainly used for operations such as grinding, cutting, deburring, and polishing of metal or non-metal materials, and has a wide range of applications in fields such as machining, automotive manufacturing, aerospace, and precision instrument manufacturing. According to different processing requirements, grinding wheels with different particle sizes, hardnesses, and shapes can be selected to complete specific tasks.

[0003] In the grinding wheels of the prior art, many grinding wheels adopt an integrally formed design, which means that the grinding wheel is a whole part made of a single material and structure. Although such a designed grinding wheel may be simpler in manufacturing and have higher strength, there are also some obvious disadvantages. First, if a certain part of the grinding wheel is damaged or severely worn, usually the entire grinding wheel needs to be replaced instead of just replacing the damaged part, which undoubtedly increases the usage cost. Second, when performing maintenance or replacing the grinding wheel, since the grinding wheel is a fixed integral structure, often the entire grinding wheel together with its protective cover needs to be removed. Such a process not only takes time but also may result in additional consumption of human and material resources, increasing the complexity and difficulty of the maintenance work.

[0004] In view of this, it is necessary to improve the above-mentioned defects.

[0005] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of implication that this information constitutes prior art already known to those of ordinary skill in the art.
