Grinding machine is a machine tool that uses grinding tools to grind the surface of workpiece. According to the statistics of China Machinery Industry Federation, from January to September 2012, the national grinder tool industry completed a total industrial output value of 568.007 billion yuan, a year-on-year increase of 11.37%, a sales output value of 550.687 billion yuan, a year-on-year increase of 11.04%, and the grinder tool industry achieved an export delivery value of 33.764 billion yuan, a year-on-year increase of 16.39%. At present, grinding machine enterprises all over China have actively adjusted their product structure, further developed new grinding machines and new grinding technology, and a number of major achievements of grinding machine R & D projects have emerged.

The development of mkb7025 CNC track plate special grinder by Hangzhou Machine Tool Group Co., Ltd. is one of the heroes of high-speed railway construction. The first set of track plate grinder has created an unprecedented speed record for new product development from design, manufacturing to installation and commissioning. It is praised by the society as "completing the innovative research and development of track plate grinder for high-speed railway construction at the speed of high-speed railway". The track plate grinder developed by Hangzhou Machinery Group has continuously refreshed its production efficiency, creating a good record of processing 120 track plates per day.

Shanghai machine tool factory has launched a new generation of high-efficiency precision cylindrical grinder. The maximum rotation diameter of the machine tool is kept at 500mm, the maximum workpiece length is 3000mm and the maximum workpiece weight is 1000kg. The machine tool adopts the high-efficiency and high-precision dynamic and static pressure bearing newly developed by the company, and adopts the bearing support structure with independent intellectual property rights. On the basis of fully ensuring the high-precision, high-speed and uniform rotation support of the spindle, it realizes the grinding of super large cutting amount, and its grinding efficiency is more than three times that of the original model.
