20+ Years of R&D
Dr. Zhao Ning, after 20 years of face gear research at a national institute, founded Laser Transmission in 2023 at age 63 to commercialize his work and advance global mechanical transmission industrialization.
2006
In 2006, we pioneered the ellipsoid hob and the hobbing process for face gears, making face gear hobbing a practical reality.
2012
In 2012, we created the dish-wheel grinding process for face gears, attaining grade 6 accuracy in face gear grinding.
2012
In 2012, we developed a measurement method for face gear tooth surface accuracy, enabling precise tooth surface measurement.
2014
In 2014, we created the worm-wheel grinding process for face gears, attaining grade 5 accuracy in face gear grinding.
2017
A CNC face gear grinding machine with a worm-type grinding
wheel,developed in 2017.
2020
The second-generation CNC face-gear worm grinding machine tool
developed in 2020.
2023-2026
A fatigue strength test platform for face gears has been established,capable of performing standard gear fatigue tests and engineering verification tests.LASER GEAR has built a complete technical system for face gear transmission design and manufacturing.
