Lenses are made from materials such as glass or plastic, and are ground and polished or molded to a desired shape.The essence of polishing and grinding is the same, both are the result of sharp and hard abrasive particles performing small cutting actions on the surface of glass. However, due to the use of finer particle polishing agents, micro cutting can be carried out within the molecular size range. Due to the close fit between the polishing mold and the workpiece surface, the tangential force during polishing is particularly large, causing the micro trace structure of the glass surface to be cut off, gradually forming a smooth surface.
【Application】
It is suitable for optical lens polished.
