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.

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
