Gear Shaping & Hobbing
High-accuracy gear production services for complex gear profiles used in aerospace, defense, industrial, and precision equipment applications.
Supported by a highly experienced gear manufacturing engineering team, PMI supplies precision gears to demanding marketplaces such as aerospace and defense, where performance, dimensional control, and reliability are essential. This expertise is integrated into PMI’s broader manufacturing ecosystem including precision machining, engineering services, and testing.
Common Applications
- Aerospace transmission and powertrain components requiring high accuracy and repeatability.
- Internal and external precision gears and splines where geometry dictates shaping or hobbing method selection.
- Shaft-mounted gear elements and ring gears used in high-load assemblies.
- Prototypes through production runs where engineered tooth form and surface condition are vital.
Technical Range
PMI’s gear shaping and hobbing capability covers a wide set of gear cutting processes designed for both standard and complex gear geometries, including:
- Precision Gear Hobbing: Production of external gear tooth profiles using specialized hobbing cutters, producing accurate pitch, form, and helix control suitable for a range of gear sizes and tooth counts.
- Precision Gear Shaping: Internal and external shaping operations for gears and splines where geometry or part configuration makes hob cutting impractical.
- Gear Broaching Support: Capability to support broaching operations where required for internal keyways or splines associated with gear components.
- Gear Tester Integration: Gear testing resources to verify tooth profile, pitch accuracy, and overall gear quality as an integrated part of the gear production workflow.
OnSite Equipment
PMI supports gear shaping and hobbing with dedicated gear manufacturing equipment, including:
- Purpose-built gear hobbing platforms capable of cutting precise external tooth profiles across a range of sizes and tooth forms.
- Gear Shaping Machines configured for controlled internal and external shaping operations, supporting complex or hard-to-reach gear geometries.
- Fixtures and broach tooling to produce internal spline, keyway, and seat features where required.
- Gear Testers & Metrology integrated into the gear workflow for verification of form, spacing, and quality.
