Powder metallurgy has become one of the dynamic aspects of new materials science, and powder metallurgy technology has been widely applied in fields such as transportation, machinery, electronics, aerospace, weapons, biology, new energy, information, and nuclear industry. In order to meet market demand, Shenyang Haimer CNC Machine Tool Co., Ltd. has independently developed a powder metallurgy CNC double end grinder. Its main functional components such as the electric spindle are imported from Japan, and the machining accuracy can completely replace that of similar imported machine tools. Flatness, parallelism, verticality, etc. can all reach 0.002mm, while the machine tool price is only 60% of imported machine tools.
Powder metallurgy CNC double end grinder
At present, the powder metallurgy CNC double end grinding machine has been confirmed by leading powder metallurgy enterprises in Shanxi, Ningbo and other regions. The following is a case of a powder metallurgy leading enterprise in Ningbo purchasing our company's powder metallurgy CNC double end grinding machine for powder metallurgy automotive rotor double end grinding.

After the powder metallurgy CNC double end face grinder was put into the market, the response was very good. It not only solved the problem of customer processing accuracy, but also optimized the processing technology, shortened the processing cycle, improved productivity, doubled the shift production directly, and reduced the scrap rate. The customer was very satisfied. Our company not only has powder metallurgy CNC double end face grinders, but also independently develops CNC internal cylindrical grinders, CNC single end face grinders, center hole seat surface grinders, hard lathes, etc. The machining accuracy can all reach 0.002mm. The machining accuracy of imported machine tools is comparable to that of domestic machine tools.
