Factors that affect diamond abrasive wear include the following parts:Hard particles or protrusions go into the friction surface and make many grooves on the surface of softer materials, but finally cause the migration of materials. This kind of wear phenomenon is known as abrasive wear. In most cases, the higher the hardness of materials, the better the wear resistance; The wear extent will be increased with the average size and hardness of wear particles increasing, etc.

The working surface passivation phenomenon of grinding disc will appear after a period of time. If it continues to be used, which will aggravate the friction between grinding wheel and the workpiece surface, thus affecting the workpiece surface quality. Therefore, people should choose the appropriate time dressing grinding wheel in a timely manner. Grinding disc dulling can be divided into three forms, namely abrasive grain dulling, grinding wheel shape distortion and grinding wheel blockage.

A finishing method of grinding disc: Diamond is the most commonly used dressing tool. It has very high hardness, whose sharp angle is 70 °-80 °. When dressing, abrasive grains run into the hard tight tip of diamond, and will break and form new surface. Because the contact area between diamond and polishing disc is small, thus the elastic deformation is also small, which can obtain fine finishing surface.

Super abrasives refers to the abrasive products that are made of synthetic diamond and cubic boron nitride, which is another big series of abrasive products. Its advantages mainly concentrate in the following several aspects: strong processing ability, less wear less, long use cycle, high grinding ratio, etc.

Diamond grinding disc is often used in our daily life, but what specific and related significance on earth? First of all, it is used to carry on abrasive layer, and then firmly clamp on the spindle of grinding machine with flange when in use.
