• 1. Polishing of Optical Lenses

In the optical field, high – quality lenses are of vital importance to the performance of optical instruments. From camera lenses to the lenses of microscopes and telescopes, extremely high – quality surface is required. Diamond polishing technology can meet this high – precision requirement. During the lens – polishing process, diamond micropowder is evenly dispersed in the polishing fluid, forming a grinding layer between the polishing pad and the lens surface. By precisely controlling polishing parameters, such as polishing pressure, polishing speed, and polishing time, the roughness of the lens surface can be reduced to the nanometer level. This ultra – smooth lens surface can minimize the scattering and reflection losses of light to the greatest extent, thereby improving the imaging clarity and resolution of optical instruments.

• 2. Polishing of semiconductor materials

With the rapid development of semiconductor technology, the requirement for the flatness of material surfaces in chip manufacturing is getting higher and higher. As the basic material for chip manufacturing, silicon wafers rely on diamond in the polishing process. In the chemical – mechanical polishing (CMP) process, diamond abrasives and chemical etchants work in synergy. Diamond particles remove the mechanically damaged layer and impurities on the surface of the silicon wafer, while the chemical etchant forms an easily removable softened layer on the surface of the silicon wafer. The two complement each other, enabling the surface of the silicon wafer to achieve atomic – level flatness. This flatness is crucial for subsequent chip manufacturing processes such as lithography and etching, and it directly affects the performance and yield of chips.

• 3. Polishing of metal parts

In the field of mechanical manufacturing, the surface quality of metal parts affects their assembly accuracy and service life. For high – precision mechanical parts, such as aero – engine blades and automobile engine cylinders, diamond polishing can effectively remove burrs, scratches and oxide layers generated during the processing. Polishing metal parts with diamond grinding paste or diamond grinding wheels can not only improve the surface finish of the parts, but also improve the surface stress state of the parts, and enhance their fatigue resistance and corrosion resistance.
