Precision grinding technology is essential for the machining and production of precision parts.
In semiconductor/LCD, MLCC, and secondary battery fields, especially precision parts are widely used.
The problem with general grinding technology is that it has to be worn continuously depending on the amount of wheel wear after grinding, but it is difficult to maintain the same quality because the condition of the wheel surface changes slightly after dressing. To put it simply, ELID grinding technology can be described as a technique of grinding while continuously dressing.
Accordingly, 21C is implementing high-precision grinding based on its own ELID technology and know-how, and the products produced through this process show high-precision flatness and quality that are difficult to produce in general.
