Problems solved by technology

[0003] At present, my country's precision machining research and production level is still far behind developed countries, most enterprises still generally use single-side grinding, and the production efficiency is low

However, due to the imperfect structure and control system of the traditional double-sided grinding machine, the processed product has poor flatness, low processing efficiency, and cannot meet the requirements of processing accuracy and surface quality. Therefore, it is necessary to improve the traditional grinding equipment and develop a Precision double-sided grinding machine with high machining accuracy to meet the requirements
