CNC Machining for Aluminum Gearbox & Transmission Housings

The gearbox housing is manufactured using multi-axis CNC milling technology, ensuring dimensional stability, structural rigidity, and precise alignment between critical functional features. • 3-axis / 4-axis / 5-axis CNC milling for complex outer profiles and internal cavities • Precision boring and drilling for bearing holes and coaxial features • Thread tapping / thread milling for mounting and assembly interfaces • Secondary finishing operations on sealing surfaces and bearing seats This machining approach guarantees high positional accuracy, excellent surface finish, and repeatable quality in batch production.   Commonly machined from high-strength aluminum alloys: • Aluminum 6061-T6 – excellent machinability and cost efficiency • Aluminum 7075-T651 – aerospace-grade strength for demanding load conditions Material selection is optimized based on weight, strength, thermal performance, and application requirements.   Material       Tolerance & Quality Control • Bearing…
