 ■ Luren Precision was initially established for manufacturing and researching gear cutting tools. This technology was first developed by the Mechanical Industrial Research Laboratories at the Industrial Technology Research Institute in Hsinchu, Taiwan. In 1995 Luren built the first production line for hobs and shaving cutters. In 1996 Luren was already supplying gear cutting tools to many international markets, such as Europe, America, and Asia. Through many successful years of gear cutting tool manufacturing, gear cutting tool software development and gear grinding machine development, Luren brings you the all new LGA-3020 CNC Continuous Generating Gear Grinding Machine.

■ LGA-3020 is built on a Reishauer AZA machine base, utilizing an advanced Siemens Sinumerik 840D CNC controller, highspeed workpiece spindle, and grinding wheel spindle. Luren’s highly efficient generating gear grinding and impressive gear grinding results are achieved by implementing a Luren designed and created gear grinding software which acts as an interface between Luren grinding machine and the Siemens 840D controller. Minimal CNC experience is necessary to operate this machine.

LGA-3020 is built on a Reishauer AZA machine base. This type of base has been used for many decades with exceptional results. The high rigidity of this type of base considerably adds to the overall performance of the LGA-3020.

LGA-3020 is equipped with the most advanced Siemens CNC controller available and the high precision electronic gear box module supplied by Siemens. Also integrated in the machine are an 8-axis close-loop servo control system and a direct drive motor such that all axes move simultaneously and very accurately.

■ LUREN’s intelligent gear grinding software is a Windows-based interface which has been carefully designed to support the complete grinding process. The operator does not need comprehensive CNC training to operate the LGA-3020 since Luren’s grinding software interfaces with the Siemens CNC controller to calculate all the necessary data to complete the CNC program. LGA-3020 brochure


About Us

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.
