Two polishing stages of optical machining polishing process

The fine grinding and polishing stages complement each other, jointly determining the final quality of the optical processing and polishing process.
Optical machining and polishing processes primarily involve two key stages: fine grinding and polishing.
The main objective of the fine grinding stage is to use mechanical cutting to remove most of the material from the workpiece surface, forming a preliminary surface structure. This stage typically involves tools such as sandpaper and grinding wheels, mechanically removing uneven parts of the surface to prepare for subsequent polishing. During fine grinding, a layer of unevenness is formed on the workpiece surface, which helps the polishing stage better remove residual material.
The polishing stage immediately follows, aiming to further reduce the surface roughness of the workpiece to achieve a mirror-like effect. Polishing methods vary, including mechanical polishing, chemical polishing, and electropolishing. Mechanical polishing relies on cutting or plastic deformation, commonly using tools such as oilstones and wool wheels; chemical polishing utilizes the selective dissolution of chemical media to remove surface material; electropolishing combines chemical and electrochemical effects to obtain a very smooth surface.
In short, the fine grinding and polishing stages complement each other, jointly determining the final quality of the optical machining and polishing process.
