Gear Machining
Gear Machining Capabilities – Weforging
At weforging manufacturing, we specialize in custom gear machining for industrial applications. Our capabilities span from hot forging and ring forging of gear blanks to precision CNC machining, hobbing, shaping, grinding, and surface treatments. We provide OEMs across Europe and North America with complete gear solutions, tailored to precise standards.
What Is Gear Machining?
Gear machining is a complete manufacturing process that transforms forged or cast gear blanks into finished gears with precise tooth profiles and tight dimensional tolerances. The workflow typically includes turning, hobbing, shaping, broaching, grinding, and heat treatment. Each step enhances gear strength, surface finish, and overall performance, ensuring reliable operation in transmissions, drive systems, and heavy machinery.

Gear Blank Forging (Hot & Ring Forging)
We produce high-strength gear blanks through:
- Hot forging of gear blanks with improved grain structure and fatigue strength
- Ring forging for large-diameter gears, enhancing concentricity and cost-efficiency
- Pre-machining of forged blanks to allow minimal stock removal
Materials: Alloy steel (42CrMo, 20CrMnTi, 18CrNiMo7-6), stainless steel, tool steel
Gear Machining Processes
Our CNC gear machining services include:
- CNC turning and milling of forged gear blanks
- Gear hobbing and shaping for module sizes 1 to 12
- Spline cutting, broaching, and tooth grinding
- Surface finishing: carburizing, nitriding, induction hardening
All gears are machined to AGMA, DIN, or ISO 1328 standards, with precise control over runout, tooth form, and pitch deviation.
