What is optical grinding? Optical Grinding Machine, also known as PG (Profile Grinder), is a high-precision machining process. With the plotter, the plotter plots the graphics to be processed on the film, the film is attached to the projection screen and corrected, and the processor will perform the molding according to the graphics on the film.

Optical grinding is suitable for the forming of high-hardness materials, such as tungsten or hard alloy workpieces, and occasionally high-speed steel workpieces. Generally, the workpiece is processed with a blade and a punch, a terminal, a precision half-stroke punch, a lower die block, and a stripping plate.

The development of the PG optical grinding machine tool industry in China is still very backward, and it cannot be compared with the Japanese original PG optical projection grinding machine. There are few optical grinding machines that are assembled and re-branded in China. It is said that an optical grinding manufacturer in Japan has only 120 workers and can produce 200 optical grinding machines a year. How do so few people produce such a large number of advanced machines? This is because Japan's mechanical parts industry is very developed, optical grinders need accessories from castings, projectors, to servo motors, to control systems, as well as oil temperature cooling, wind vacuum can be purchased from the market, It will be assembled by these 120 people. Therefore, in order to develop the optical grinding machine tool industry, China must first develop the mechanical parts industry and basic machinery and equipment. Only China's PG optical grinding machine tool industry has developed to produce optical grinding machines made in China, and China's PG optical grinding processing manufacturers can develop better.
