Supplier Custom Hypoid Bevel Gears Used in Robotic Arms

Hypoid gears can be machined using two different methods: grinding and lapping. Domestic equipment can process hypoid gears, but high-precision, high-end processing is usually done by foreign equipment, such as Gleason and Oerlikon.

In the gear grinding process, face milling is recommended for the gear cutting process. On the other hand, it is recommended to use face hobbing during grinding. Gears machined with face milling have bevel teeth, while gears machined with face hobbing have contour teeth.

A typical machining process includes rough machining after preheating and finishing after heat treatment. For face hobbing, the gears must be ground and fitted after heating. Although the gears using the grinding technology do not need to be matched in theory, the matching method is still generally used in actual operation to solve the problems of assembly errors and system deformation.
