This custom L-shaped aluminum gearbox housing is manufactured by 5-axis CNC milling. It adopts an integrated thick-wall structure with multiple bearing cavities, flange mounting holes, threaded holes and positioning bosses distributed on different surfaces. The intersecting bore chambers are machined in one clamping, which ensures strict parallelism, perpendicularity and center distance tolerance between the holes.
We precisely control key indicators including bore size, surface roughness, flatness of mating surfaces and positional tolerance. The one-piece solid structure provides high rigidity and anti-deformation performance, which is critical for stable gear and bearing operation. The blue protective film on the surface prevents scratches during machining, handling and transportation and can be peeled off before assembly.
6061, 6063 and 7075 aluminum alloy are available for selection. Surface treatments such as anodizing, hard anodizing, sandblasting and passivation can be provided according to your requirements. Aluminum alloy features lightweight, good vibration damping and excellent thermal conductivity, helping to dissipate heat generated during gear transmission.
This multi-cavity aluminum transmission housing is widely used in automated transmission modules, robot speed reducers, special machine tool gear units, packaging machinery and test equipment. It serves as the main carrier for gears, bearings and shafts in power transmission assemblies.
