Rotors Machining: Beijing Nankou Railway Transit Machinery Co., Ltd. is a professional manufacturer of mechanical transmission system, compressor integration system and railway turnout system. Among all these, rotor is one of our major products. With various high-precision CNC machining, testing and measuring equipments (Holroyd Rotor Grinding Machine, Hardinge CNC Outer Cylinder Grinding Machine and Zeiss CMM), we can machine rotors with the maximum diameter of 360mm and the maximum length of 1600mm, including all kinds of profiles. Our production capacity is 400-500 per month. Relying upon advanced processing technology and stable performance, our rotors have been sold to the United States and the Great Britain. They have been largely used in industrial refrigeration and manufactory industries, highly regarded by the customers.
Rotor with superior performance The profile is the famous third-generation rotor profile. All teeth profile curve are circular arc or envelope of circular arc. It adopts SCCAD software to design. The features of the profile are good sealing, small loss and high efficiency. Thanks to excellent machining equipments, the machining level of rotor is at the top of the world. The types of the rotors are various and the dimensions of them are full, which fulfills the requirements for different customs. The design of rotor directly influences air compressor performance. Specialized design team and superior machining process and equipments can reduce R&D cycle and fulfill the market requirement. The practice proves that the superior performance and huge market share are accepted by our customs.
