Description

Technical Field

[0001] The utility model relates to the technical field of grinding tools, in particular to a diamond grinding wheel grinding tool which is easy to replace. Background Art

[0002] Diamond grinding wheel is a kind of high-efficiency grinding tool. It is made of diamond abrasive as raw material and consolidated by different binders. It usually has a circular structure with a central through hole. Diamond grinding wheel is generally composed of three parts: diamond abrasive layer, transition layer and matrix. The diamond abrasive layer is composed of abrasive, binder and filler. It is the working part of the grinding wheel and directly participates in the grinding process. The transition layer is composed of binder, metal powder and filler. It plays the role of firmly connecting the diamond layer to the matrix. The matrix is used to receive the abrasive layer and is firmly clamped on the spindle of the grinder with a flange when in use. The material of the matrix depends on the type of binder. For example, metal binder products use steel and alloy steel powder as the matrix; resin binder products use aluminum alloy and bakelite as the matrix. The hardness of diamond abrasive determines the main characteristics of diamond grinding wheel, which enables it to efficiently grind difficult-to-process materials such as cemented carbide, glass, ceramics, etc. Diamond has high wear resistance and the grinding wheel wears less. The longer the use time, the smaller the change in size, shape and morphology of diamond abrasive grains during the grinding process, making it more suitable for high-precision processing. At the same time, diamond has very good thermal conductivity, which is conducive to the evacuation of heat, avoiding burns, cracks and falling of the workpiece, and greatly improving the quality of workpiece surface processing.
