In the manufacture of tools and moulds, grinding is the last process to ensure the accuracy and quality of products.
In addition to the grinding machine itself, the grinding process also plays a decisive role. When grinding brittle materials, due to the physical properties of the material itself, the formation of chips is mostly brittle fracture, and the surface after grinding agent is relatively rough.
In some applications, such as optical elements, such a rough surface must be polished.
Although it can improve the surface roughness of the workpiece, it is often reduced after polishing because it is difficult to control the shape accuracy. In order to solve this contradiction.
In the late 1980s, many companies and research institutions in Japan, Europe and the United States successively pushed back two new grinding processes: plastic grinding and mirror grinding.
