Precision CNC Machining and Gearbox Manufacturing Factory
In mechanical power transmission and motion systems—such as cycloidal reducers, planetary gearboxes, and micro DC gear motors—reliability depends on micron-level tolerances. For global OEM and ODM buyers, selecting an overseas manufacturing partner requires verifiable production assets and rigorous quality control. At Shenzhen Wan Yuan Transmission (WYOO), our modern manufacturing facility delivers high-precision transmission parts through advanced Precision CNC Machining, automated gear shaping, and traceable metrology.
Advanced Precision CNC Machining & Gear Production
To produce tight-tolerance motor shafts, spur gears, pin-wheel housings, and transmission housings, our facility relies on dedicated Precision CNC Machining centers from industry-leading manufacturers:
- Japanese Tsugami S206A Swiss-Type CNC Lathes: Equipped for high-speed, multi-axis turning and milling of precision motor shafts and pinions. The Swiss sliding-headstock design prevents deflection on slender shafts, holding tight dimensional tolerances within ±0.003 mm.
- GF AgieCharmilles CUT E 350 Slow Wire EDM: High-precision Swiss wire-cut electrical discharge machining utilized for cutting hardened steel cycloidal disc profiles, specialized keyways, and intricate gear teeth where conventional cutting tools cannot reach.
- Taikan T-600B High-Speed Drilling & Tapping CNC Centers: High-rigidity vertical machining centers dedicated to rapid, repeatable Precision CNC Machining of aluminum gearbox housings, mounting flanges, and end-covers.
- TOR & Ningjiang CNC Gear Hobbing Machines: Dedicated CNC gear hobbing and shaping equipment engineered specifically to produce low-backlash spur gears and planetary gear stages with optimized tooth surface finishes.
Automated Injection Molding & Sub-Assembly Lines
For hybrid metal-plastic gear sets and high-volume commercial automation components, precision molding consistency is vital across continuous batch production:
- Fanuc Roboshot α-S100iB All-Electric Injection Lines: Fully automated, ultra-stable electric injection molding ensures zero thermal degradation and micro-level consistency on precision POM/nylon gear sets and motor frames.
- Haitian Precision Injection Molding Machines: Dedicated workcells for robust external enclosures, structural covers, and protective terminal shells.
- Servo Press Fitting & Assembly Lines: Programmed servo presses monitor pressure-versus-displacement curves in real time during bearing insertion, preventing shaft deflection or uneven pre-loads.
Quality Assurance Lab: Verifying Sub-Arcminute Accuracy
Precision manufacturing is only as dependable as the metrology behind it. Our dedicated, climate-controlled inspection lab handles incoming raw materials, first-article inspections (FAI), in-process checks, and 100% pre-shipment functional testing:
- Hexagon Inspector S Coordinate Measuring Machine (CMM): High-precision multi-sensor CMM utilized to measure geometric dimensioning and tolerancing (GD&T), true position, roundness, and concentricity across complex cycloidal gearbox housings.
- Optical Profilometers & Contour Measuring Systems: Non-contact 2D/3D profile analysis verifying micro-gear tooth geometry, pitch deviation, and lead error.
- Surface Roughness & Micro-Hardness Testers: Benchtop optical hardness testers confirm heat-treatment integrity (case hardening/nitriding) on output shafts and cycloid pins to ensure long-term wear resistance.

Why Direct Manufacturing Matters for Your Projects
Working directly with an equipped manufacturing plant eliminates middleman communication bottlenecks and ensures end-to-end quality control. Our standard quality workflow includes raw material spectral analysis, dynamic torque testing, noise level testing in an acoustic room, and full dimensional inspection reports accompanying every shipment.
Whether your application requires custom shaft modifications, dynamic torque-ratio alterations, or rapid batch prototyping, our engineering team can review your 2D/3D CAD drawings (STEP/DWG) and provide DFM (Design for Manufacturability) feedback within 24 hours.
