Diamond grinding disc refers to a disc type grinding tool used in grinding machines, consisting of a disc body and diamond grinding blocks. Diamond is welded or embedded on the disc body, and the working surface is smoothed and polished by the high-speed rotation of the polishing machine.


Due to the characteristics of diamond abrasives (high hardness, high compressive strength, and good wear resistance), diamond grinding tools have become ideal tools for grinding hard and brittle materials and hard alloys in grinding. They not only have high efficiency and accuracy, but also have good roughness, low tool consumption, long service life, and can improve labor conditions. Therefore, they are widely used in industries such as electronics, optoelectronics, glass products, electronic tubes, and precision machining, Especially in recent years, the application field of diamond grinding discs has become increasingly widespread.

What should I pay attention to when purchasing diamond grinding discs?


Firstly, the size of the diamond grinding disc:


The diameter of diamond grinding discs is generally between 203-305MM, and the actual size is determined based on the size of commonly processed materials;


Secondly, in terms of diamond grinding disc particle size:


Diamond grinding discs, like sandpaper, have a larger particle size and a finer surface particle size that is smaller and coarser. Generally, three types of grinding discs are used in combination, namely coarse, medium, and fine, to achieve the best results.


Finally, the most important and crucial aspect is the quality of diamond grinding discs, which should be approached from the following three aspects:


1) Look at the packaging


2) Look at the back of the grinding disc


3) Check if the particle size of the disc mill is uniform


In short, strict screening is necessary when purchasing diamond grinding discs.
