CNC Bevel Gear Cutting and Grinding Machine

■ LUREN PRECISION has developed a six-axis five-synchronized movement machine to manufacture bevel gears. This system utilized Gear Theory, Computational Geometry and Optimum Design Method, built a knowledge base for production intelligence, and developed a graphic interface based manufacturing system that allowed operators to easily complete the production of bevel gears.

■ LVC-100 uses a specific Cup Type Milling Cutter, to manufacture bevel gears in high efficiency. It is further equipped with a specifically designed HSK tool holder that provides flexibility and precision for tool replacement as well as production stability. Besides, B and C axes adopt high-precision direct-drive motor, to increase production precision. There is no need of backlash adjustment problem that happens with a worm gear after wearing, increasing reliability and allowing long-term multi-axis synchronized movement in production. Due to the use of direct drive motor, there is no backlash problem that happens with worm, allowing accuracy in gear production and eliminating the problem with different precision on left and right flank.

■ LVG-100 also uses HSK specifically designed tool holder and direct drive 4/5 axes. It is equipped with high speed spindle, magnetic filter, paper filter system, uses electroforming CBN grinding wheel to provide correction for the deformation after heat treatment to improve gear accuracy and reduce noise. The use of HSK tool holder allows automatic replacement of grinding wheels in different fine and coarse levels, and provides both manufacture efficiency and desired fineness.

About Us

Shi-duang Chen

Luren Precision President, Shi-duang Chen

    LUREN'S initial Italy technology acquisition along with long-term support of ITRI and close relationships with academic and research institutions has give Luren the ability to significantly increase R&D capabilities and key technologies, allowing Luren to develop two successful business units, which are Gear Cutting Tools, and Gear Grinding Machines.  

Luren began its international sales  and marketing for its gear grinding machines under the Luren brand name since 2005.

LUREN was established in 1994 in Hsinchu Science Park with nine elite members from the mechanical labs in ITRI, a government-sponsored research facility in Taiwan. Now Luren has over 250 employees and as Luren closes in on nearly two decades of prosperity, many of my original team members and I have been blessed with the ability to participate and witness the most prosperous times of precision mechanical industrial development in Taiwan history.

Before Luren, gear cutting tools and gear grinding machines had to be imported from other countries into Taiwan. As the result of high tooling costs and long delivery schedules, gears made in Taiwan were not competitive in the global market. Luren was then urged to establishment by the Taiwan Ministry of Economic Affairs, the Taiwan Association of Machinery Industry, ITRI, and major gear manufacturers in Taiwan. Luren missionized itself to advancing the gear technology industry in Taiwan and supplying top-quality precision gear manufacturing tools to Taiwan gear manufacturers.

With focusing on key technologies in R&D, the manufacturing process and our quality assurance process, we are able to achieve the best cost performance in Asia. We’have also developed our own smart grinding software for our various grinding machines to dramatically increase our customer’s productivity by decreasing the learning curve and increasing the time the machine is utilized in production versus down time. This is a clear competitive advantage that makes Luren’s grinding machines stand out in the crowd.

Nevertheless, we have never been satisfied by our accomplishments. In addition to our continuous growth and significant contributions to the gear community we also want to continue to advance our global presence. Our vision is to supply our top-quality gear cutting tools and gear grinding machines to gear manufacturers worldwide, fulfilling their demands and helping them to increase their competitive edge, securing their place in the world market place.
