As a professional CNC machining supplier in China, BestPro provides special CNC machined gearbox housing from casting blanks, or make direct CNC machining for those low-volume or urgent needs. All of our housings are machined to your prints and tolerances allowing for bore tolerance, flatness, concentricity for optimal gear performance.
| Material | Suggested Application | Heat Treatment | Surface Finish | Performance Notes |
| Aluminum 6061/6082 | Medium load, lightweight gearboxes | Anneal / T6 | Milling / Polishing | Low weight, corrosion resistance |
| Alloy / Carbon Steel | Heavy-duty industrial | Q&T / Induction | Milling / Polishing | High strength, fatigue resistant |
| Stainless Steel 304/316 | Corrosive or hygienic environment | Anneal / Age Harden | Passivation / Polishing | Corrosion resistant, precise bore |
Bore tolerance & concentricity: Ensures the correct gear engagement and smooth operation.
Surface finish: Wear strength, good lubrication performance and long service life of the gearbox.
Keyways, bolt holes and mounting surface machined to customer specifications.
| Process | Description | Best Use |
| CNC Machining | 3/4/5-axis turning, milling, boring | Precision housings, prototypes, small batch |
| Forging + CNC Finish | Forged blanks, machined to tolerance | High-load, long-life housings |
| Casting + CNC Finish | Investment/die-cast blanks → CNC finish | Cost-effective for larger housings |
Prototype & validation: CNC samples checked for bore, flat, and concentric; heat treating utilized if required.
Small and medium volume: CNC or cast/forged blanks → processing → heat treatment → final inspection.
Long-term supply: Sufficient and stable production, quality control, high quality service and prompt delivery.
Our CNC machined gearbox housing factory derict custom order mainly exported to Europe, North America and Japan.
All raw materials and finished products 100% checked, strict tolerance and stress testing.
Clients are given immediate updates and photos, as well as reports on the condition of the products inspected.
