Common Manufacturing Processes for Gears
2026-01-29
The production of gears involves several key processes to achieve the required shape, accuracy, and material properties. Gear cutting is the primary forming method, with processes like hobbing (for spur and helical gears), shaping (for internal gears and clusters), and broaching being widely used. Gear grinding is a precision finishing process that removes small amounts of material after heat treatment to achieve very high accuracy and surface finish, essential for high-speed or low-noise applications. Most high-performance gears undergo heat treatment, such as carburizing or induction hardening, to increase surface hardness and wear resistance while maintaining a tough core. The choice of process—machining, finishing, and heat treatment—depends on the gear's material, required precision, quantity, and performance specifications.
