Company Introduce

Founded in 1952, Nanjing Process Equipment Manufacturing Co., Ltd. is a key subsidiary enterprise of Nanjing State-owned Assets Supervision and Administration Commission and the vice president unit of China Machine Tool and Tool Industry Association. The company is a key high-tech enterprise of the National Torch Plan, a single champion demonstration enterprise of the manufacturing industry of the Ministry of Industry and Information Technology, and a "science and technology reform demonstration enterprise" of the State-owned Assets Supervision and Administration Commission of the State Council. The company has won the honors of "National Quality Benchmarking in 2021" and "Jiangsu Provincial Governor's Quality Award Nomination Award in 2023", and has been awarded excellent grades in the special evaluation of local "science and technology reform enterprises" organized by SASASAC of the State Council for three consecutive times. The company is mainly engaged in rolling functional components represented by ball screw pairs and rolling guide pairs. The products have the characteristics of "high efficiency", "low carbon", "energy saving" and "green". They are widely used in high-end CNC machine tools, artificial intelligence, 3C automation and other fields, and are the key core components of high-end CNC equipment. The company firmly grasps the powerful opportunity of the development of the "industrial mother machine" industry, breaks through the blockade of foreign technology, carries out high-quality industrialization projects of ultra-high precision screw and guide rail for high-end machine tools, breaks the situation of long-term dependence on imports of key core components, successfully realizes the substitution of imports, and accelerates the development of new quality productivity. The company has "Jiangsu Province Certified Enterprise Technology Center", "Machinery Industry Rolling Functional Components Engineering Research Center", "Jiangsu Province Engineering Technology Research Center", is a member of the Ministry of Industry and Information Technology High-end Equipment Manufacturing Technology Collaborative Innovation Center and High-end CNC Machine Tool Innovation Alliance, and has presided over 9 and participated in 42 national science and technology projects. He presided over and participated in the compilation of 41 national and industrial standards.
