Bevel gears mainly include involute spiral bevel gears (including offset hypoid gears) and constant teeth extended epicycloid bevel gears.After decades of theoretical research and technical breakthroughs, the team has mastered the digital design and CNC machining technology of involute and constant teeth. They have developed CNC milling machines for involute and constant teeth, achieving the localization of high-end machine tools and equipment, which can replace similar gear making equipment abroad.
