Capabilities
Custom Gear Manufacturing Capabilities
We offer a full spectrum of gear manufacturing services, ranging from 0.1 module micro gears to precision transmission components up to Ø300 mm. Combining skiving, hobbing, shaping, broaching, and grinding processes, we deliver ready-to-assemble finished products.
Capabilities Details
Power Skiving
Capable of machining internal and external gears with shoulders. Complex gear profiles that most suppliers cannot accomplish in a single setup are easily achieved.
Gear Hobbing
High-precision fine-pitch hobbing and high-speed horizontal hobbing. Ideal for high-volume production of external gears with excellent accuracy consistency.
Precision Gear Grinding
Hard finishing of hardened gears to correct heat treatment distortion, achieving ISO Grade 5 accuracy or higher to ensure smooth power transmission.
Gear Shaping
Internal and external gear shaping. Suitable for complex gear structures such as stepped shafts and blind gaps where hobbing is not feasible.
Gear Broaching
Internal broaching for highly efficient forming of internal splines and gears. Ideal for medium to high-volume production with superior dimensional consistency.
Wire EDM
High-precision cutting of splines and custom-shaped holes using Seibu M50B. Complemented by CNC machining centers for hub milling and weight reduction holes.
Equipment for Custom Gear Manufacturing
Our advanced gear processing equipment — including Kashifuji gear skiving machines, Ningjiang CNC hobbing machines, and Nachi gear broaching machines — enables comprehensive gear machining coverage.

Nidec Gear Shaping Machine SE25FR
Our Kashifuji KPS30 simultaneously handles internal and external gear skiving, including shoulder gears that most suppliers cannot process in a single setup. Combined with our Ningjiang CNC hobbing lines for high-volume external gears and Nachi broaching machines for tight-tolerance internal splines, our process portfolio completely eliminates outsourcing, giving you full control over lead times.

Material Selection
Our most frequently processed materials are 42CrMo (AISI 4140), 20CrNiMo (AISI 8620), and S45C (AISI 1045) for steel gears, and POM / MC Nylon for plastic gears. Full material options are listed below—if your specification calls for something not listed, contact us and we will advise on alternatives.
Quality Inspection Process
We strictly control every stage from incoming raw materials to final shipment.
process
RAW MATERIAL INSPECTION
Verify chemical composition and hardness to ensure material grades, specifications, and mechanical properties fully comply with technical requirements.
IN-PROCESS INSPECTION
Continuous monitoring of dimensions and geometric tolerances during machining to eliminate defects at the source and prevent batch rework risks.
HEAT TREATMENT INSPECTION
Post-heat treatment hardness testing and metallographic analysis to guarantee that case depth and microstructure conform to drawing specifications.
GEAR ACCURACY INSPECTION
Comprehensive testing of gear profile, lead, and pitch accuracy using gear measuring centers, issuing full inspection reports.
FINAL INSPECTION
Final review of appearance, dimensions, and packaging to ensure 100% compliance with client delivery specifications prior to shipment.
OEM / ODM Services
Whether you have complete drawings or just worn samples and conceptual sketches, we provide a complete manufacturing pathway—delivering a one-stop solution from prototyping to mass production.
Build-to-Print Manufacturing
Provide your CAD, PDF, or STEP files, and we will manufacture strictly according to your tolerances, materials, and surface finish specifications, supporting everything from low-volume trial runs to high-volume production.
Reverse Engineering & Development
No drawings? Send us your worn samples or conceptual sketches. We utilize CMMs and gear analyzers for full reverse engineering, reconstructing 3D models ready for direct manufacturing.
