Luren Precision Co., Ltd., founded in Hsinchu, Taiwan in 1994, has been dedicated in gear technology including the design and manufacture of hobs and shaving cutters. Owing to its own capabilities in software design and machine tool building, Luren manufactures 800 hobs and 500 shaving cutters monthly with its key customers in Taiwan, Japan, Korea, China, Germany, and the United States.
During the past decade, Luren also developed other gear-related business sectors like CNC grinding machine tools. A CNC hob sharpening machine was developed first, followed by a CNC worm & thread grinding machine and a CNC gear profile grinding machine (horizontal). The latest development from Luren is a vertical CNC gear profile grinding machine capable of grinding gears of 800 mm in diameter with features of automatic stock dividing, on-board inspection and rotary dressing. In total, over 100 CNC grinding machines were ordered and shipped to date.
Additionally, the company manufactures spinning pumps and oil finish pumps used in man-made fiber production, especially for polyester and nylon filament yarns or staple fibers. Luren also manufactures driven tool holders for a CNC turning center. Both VDI and BMT types are currently under development. Strict tests in noise level, temperature increase and vibration are performed for quality assurance.
After the establishment of two sales offices in Osaka, Japan in 2004, and Shanghai, China in 2008, the third overseas sales office was opened in Chicago in July, 2010. Gerald Kuo was appointed as general manager. The function of this sales office is mainly in supporting and reinforcing Luren's existing distributors of gear cutters, CNC grinding machines and spinning pumps in North America.
