Performance Highlights
Continuous generating for consistent tooth geometry
Unlike single-tooth machining, hobbing progressively forms each tooth profile in a continuous cutting action. The result: consistent tooth spacing, lead accuracy, and surface finish across full production runs.
Spline accuracy ±0.01mm
Precision indexing and controlled hobbing parameters deliver spline profiles within ±0.01mm accuracy and pitch error ≤0.015mm, ensuring uniform load distribution and reliable torque transmission.
Spur and helical gear capability
We produce straight-tooth spur gears for high-volume applications and helical gears for smooth, high-load transmission systems - with full tooth profile and lead control.
Broad material compatibility
Carbon steels, alloy steels, stainless steel, aluminum alloys, and brass are hobbed with optimized tool geometries and cutting parameters for each material.
High-volume efficiency
Hobbing is significantly faster than shaping or milling for gear and spline production. Combined with automated loading and live tooling, we support volume requirements across automotive and industrial applications.
IATF 16949-certified facility
Full PPAP Level 3 documentation available - process FMEA, control plans, capability studies - prepared to the same standard we apply to Tier 1 automotive customers.
Quality Control
Applications
Automotive Transmission Gears
Spur and helical gears for manual and automatic transmissions are hobbed with consistent tooth geometry and profile accuracy, supporting smooth engagement and load distribution across gear sets.
Steering System Gears
Helical gears used in steering racks and electric power steering systems require consistent lead accuracy and tooth form. Hobbing delivers the precision and volume required for these safety-critical components.
Splined Shafts and Hubs
Involute splines on shafts and in hubs are hobbed with ±0.01mm accuracy and pitch error ≤0.015mm - ensuring uniform load distribution and accurate centering of mating components.
Pump and Industrial Gears
Gear pumps, timing gears, and industrial drive components use spur and helical gears. Hobbing provides consistent tooth profiles and the fatigue resistance required for continuous operation under load.

Why Hobbing
For splines and gears, other methods have distinct limitations:
Broaching – internal profiles only; cannot produce external gears or long splines
Milling – single-tooth cutting; slower, less consistent tooth spacing
Shaping – reciprocating cutting; slower, less efficient than hobbing
Hobbing delivers continuous generating action - faster than shaping or milling, and capable of producing consistent tooth geometry across long production runs. For spur gears, helical gears, and splined shafts - hobbing is the production method.
