In machining, generally divided into lathe processing, milling machine processing, grinding machine processing, we usually say the car milling and grinding, with the enhancement of the degree of precision of the product, the three ways machining are also more frequent, more and more products need milling processing to meet the daily precision requirements.

Grinding machine processing is generally divided into plane grinding, internal grinding, cylindrical grinding, centreless grinding, from the original simple mechanical grinding machine to the current CNC grinding machine, its processing capacity is more and more comprehensive, to provide a good complement to the precision processing, the current market of 4-axis CNC grinding machine, can be used for ceramics, glass, and other hard and brittle materials precision processing, processing accuracy can also reach 0.001mm, which provide more options and break the international technology blockade of China's technology. At present, the domestic optical grinding machine still has to be imported to meet the demand for production and processing, in the nanometer high precision today, the precision of the grinding machine in the lathe and milling machine can not be compared to the precision machining and is even more indispensable to the grinding machine.

Precision grinding machine processing is mainly to solve a variety of high-precision dimensions, high shape precision and effective processing methods, and it can greatly improve the efficiency of parts processing, turning, milling and grinding have a roughing, semi-fine plus finishing through different processes, and gradually control the accuracy of the parts, to meet the accuracy requirements of the drawings.
