Located in Shanghai Jiading Industrial Development Zone, Shanghai Zuoren Precision Cutting Tool Co., Ltd. enjoys convenient transportation at the junction of outer ring highway and Yanjiang highway, 300 meters away from Huqiao entrance of the freeway.
　　Jointly founded by people with overseas background, Shanghai Zuoren Precision Cutting Tool Co., Ltd. is a professional manufacturer of standard and non-standard tools. The predecessor of the company is Shanghai Jiading Equipment Manufacturing Plant. With the continuous development, the company has gone through the reorganization of assets, assimilation of overseas new technologies, development of new products, introduction of advanced equipment, and adoption of automation production and computerized management; and become a professional manufacturer of tools.
　　The company insists on the quality policy of "high quality, short delivery time, and high efficiency."
　　The development of the domestic auto industry and the aviation industry drives large demand of automation machinery for tools.
　　To cater for the development of the market, the company introduces advanced equipment and technology from other countries to solve the problem of tools and provide a wide range of technical support for customers.
　　Taking lowering production costs for the customers into consideration, the company offers services of tools grinding and restructuring for the customers. The tools cover a wide range of fields and are widely used in machining centers, car engines, compressors, aerospace, military and other machinery manufacturing industries.
The raw materials of tools include:
　　Cemented carbide adopts K55SF and MGl8 super-fine particulate materials from Europe with the average granularity of 0.2~ 0.5u, hardness of HRA93, and anti-bending strength of 4000 N/mm2.
　　High-speed steel adopts SKH59 high-speed steel containing diamond elements made in Japan. After special heat treatment of the tool, it gains high toughness and small internal stress with hardness of HRC6 ~ 69 so that tool life is extended by reducing blade collapse.
　　Diamond adopts imported high-quality PCD and CBN.
　　With the development of industrialization, the customer asks for continuous improvement of tools. To extend lifespan and reduce costs of tools, coated tools are widely used, which is the inevitable trend in tool industry. To keep up with the trend, the company provides various world-class nano-coating materials including TiN, TiCN, TiALW, DLC + TiALN and DLC according to the customers’ demands. Besides, the company can tailor coating-materials according to the materials to be cut provided by the customers. In addition, the company can provide special coating for braze welding tool to avoid deformation of its shape.
　　The customers should provide the materials to be cut, cutting speed, amount of feed, cutting medium, cutting machines and tools drawings and then the company will tailor the tools for the customers based on the samples or drawings; track the service condition of the tools and provide quality service for the customers.
