Luren's gear grinding machines can achieve AGMA class 14 or DIN 4 accuracy. Luren has developed a software program based upon a Windows platform. This program makes it easier to train CNC machine operators because the program focuses on the final dimensions of gear or tool verses the individual mapping points of a CNC machine.

 ■ 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

Hob Sharpening Machine


Hob Sharpening Machine

■ Luren Precision has been manufacturing gear cutting tools for over 20 years.  With the same President, Vice President and many of the same staff since day one.  Luren's experience and commitment to perfection can be seen in everything Luren does.  With all the experience gained from reverse engineering gear drawings and manufacturing some of the finest gear cutting tools in the industry, Luren has been able to create a hob sharpening machine that is very user-friendly and very reliable.  Luren developed this machine with an advanced Windows-based operating system that basically only requires final specification of the work piece and the software, using many graphical visual aids, does the rest of the calculations for the operator. 

■ With Fanuc controls, a directive drive oil cooled motor, a linear motor and custom designed software, Luren has carefully selected and matched some of the most advanced technological components available on a CNC grinding machine to insure productivity, reliability, and most importantly high precision results.

Our History


When founded in 1994, Luren worked with ITRI and imported the design and production technologies of gear cutting tools from Samputensili, Italy, to begin the production and sale of our gear cutting tools.

Through many years of production improvements and technological advancements Luren has developed a strong R&D team which allows us to provide R&D solutions to all of our customers through our two business units of gear cutting tools and gear grinding machines. We’ve also expanded rapidly selling our gear grinding machines internationally under the Luren brand.

With the development of our machines, our long partnerships and our experience in the gear industry, we were able to develop sophisticated gear cutting software compatible with all of our machines. Our comprehensive gear cutting solutions have advanced Taiwan’s gear industry like no other. Luren remains an intricate part of the success of Taiwan’s gear manufacturing industry.
