Precision Hobbing Gears / Custom Gear Cutting Service

After machining the gear blanks, we perform gear forming through hobbing and shaping. Precision gear hobbing is used for external teeth, while internal shaping is executed for internal gears. We also offer gear shaveling to enhance tooth surface quality. These methods are vital for achieving accurate tooth geometry and transmission characteristics. Wu Hung’s equipment accommodates a wide range of gear sizes, from micro to mid-sized industrial gears, ensuring consistent pitch accuracy, alignment, and excellent surface finish for demanding applications.

Gear hobbing and shaping are important manufacturing processes to create accurate gear profiles. Our services support high-precision external and internal gear cutting for power transmission and mechanical synchronization systems.
