The four-axis control system, in which the two axes are the interpolation control axes respectively control the vertical and horizontal feed of the machine table. The other two axes control the vertical and horizontal feed of the carriage. The grinding wheel speed and the reciprocating speed of the sliding plate are all controlled by the frequency conversion control system. The grinding machine has the functions of straight line, circular arc continuous path grinding, continuous curve grinding of parameter equation curve and projection detection. The bed body and the projection box are box structures, and the internal structure thereof satisfies both the sealing property of the optical path and the rigidity of the bed. The carriage guide rail of the grinding machine table is a closed linear rolling guide, and the low-speed movement is stable and reliable, and the micro-feed motion is flexible and correct. A new sub-micron liquid-solid and gas-solid filter widely used in petrochemical, metallurgical, environmental protection and other industries has been successfully developed in Hebei Shenzhou Purification Equipment Factory and obtained national technology patents. When the hydraulic system oil temperature of the machine tool equipment rises above, the performance of the system will be greatly reduced, the machine tool failure will occur frequently, and its stability and process capability index E value will be seriously reduced, and the mass production of the product cannot be guaranteed. In order to ensure the normal operation of the hydraulic system of machine tools, many countries have added new aluminum air coolers in hydraulic systems. Its ultra-thin, ultra-light, high-efficiency, and beautiful performance changes and replaces the traditional copper tube air cooler with large volume, rough workmanship and low thermal efficiency. The series of aluminum air coolers are fully adapted to the ultra-small, high-tech, environmentally-friendly and energy-saving requirements of modern machine tools. New Air Cooler High-precision Ultra-thin and Super-hard Material Abrasives Complete Technology The new sub-micron filter is a research project of “High-precision ultra-thin and super-hard material grinding tools†undertaken by Zhengzhou Abrasives Grinding Research Institute. Technical identification. The project solved a series of technical problems. For the first time in China, the complete manufacturing technology of high-precision ultra-thin and ultra-hard material cutting wheels for metal and resin was put forward, which filled the domestic gap and possessed independent intellectual property rights in China. The precision, shape and applicable performance indicators of the high-precision ultra-thin and ultra-hard material abrasive tools have reached the international advanced level of similar products and can completely replace imported products. The technology has the characteristics of high technological innovation, wide range, difficulty, high product technology content, meets the development needs of micro-processing in China's electronic information industry, and can be applied to the processing of precision molds and precision tools, with good economic benefits. And social benefits, the market has broad prospects. (Finish) Changzhou Saina Automobile Industry Co., Ltd , https://www.sainaauto.com
