Gear cutting for custom components
Every gear geometry does not call for the same manufacturing process. We maintain a range of specialized gear-cutting equipment so the manufacturing method can be selected around the gear type, tooth geometry, size, drawing requirements and production needs.
Select a process to see the equipment and range behind it.
Gear hobbing supports the manufacture of spur gears, helical gears, worm gears and spline shafting.
Our overall hobbing equipment range runs from approximately 1/4″ to 60″, on Barber Coleman and Liebherr precision hobbing equipment.
Gear shaping supports external and internal gear requirements where shaping is the right process for the component geometry.
Our shaping range runs from approximately 1/8″ to 36″ diameter on Fellows gear shapers, including CNC gear-shaping equipment.
Dedicated Gleason equipment supports custom bevel and miter gear manufacturing.
Our equipment includes Gleason #12, #104 Coniflex High-Speed Bevel Generators and #14 Coniflex machines.
We maintain dedicated equipment for custom rack gearing, including Fellows and Whiton rack-cutting and rack-milling machines.
Rack manufacturing can be paired with custom pinion manufacturing for customer-specific rack-and-pinion requirements.
Dedicated thread-milling equipment supports the manufacture of worms, lead screws and related threaded power-transmission components.
Our gear department runs Lees-Bradner and Pratt & Whitney thread-milling equipment.
Whiton equipment supports involute gear milling and specialized manufacturing requirements, including ratchets and jaw clutches.
Our ratchet capacity extends to 30″ diameter, and jaw clutches are manufactured through 24″ diameter.
Gear manufacturing can also require finishing after tooth cutting.
We maintain dedicated Hey chamfering and Redin automatic gear-deburring equipment, along with additional deburring and gear-finishing equipment.
Gears cut to your specifications
We manufacture a broad range of custom gears and related power-transmission components — produced to your drawings, tooth geometry, pitch, material, dimensional requirements, quantities and inspection requirements.

Engineering note · equipment range vs. product range
The capacity of an individual gear-cutting machine should not be confused with the manufacturing range for every product. Our overall hobbing capability runs from 1/4″ to 60″, while our standard spur-gear range is through 36″ diameter. Likewise, bevel and miter gears are quoted through 24″ diameter × 3½″ face.
For requirements outside these product ranges, send us the drawing for a manufacturing review rather than assuming the broader machine envelope applies.
Specialized gear machines + modern CNC technology
Our manufacturing capability combines specialized gear machinery with continued investment in CNC technology — so we support both established gear-cutting processes and modern CNC manufacturing requirements.
Our hobbing department supports spur gears, helical gears, worm gears and spline shafting.
We continue to modernize our gear manufacturing operation. Our 2026 CNC investment adds a six-axis CNC gear machine, two CNC gear machines and a CNC gear shaper — part of an ongoing effort to improve accuracy, throughput, consistency and customer response time.
Gear cutting can be combined with CNC machining for other component features.
This lets gear manufacturing be supported by turning, milling, bore machining, keyways, drilled and tapped features, shaft features and other drawing-specific machining requirements.
From drawing or blank to finished component
We support more than the tooth-cutting operation alone.
Depending on your project, you can supply machined blanks for gear cutting — or work with us on a more complete manufacturing process through to the finished component.
A custom gear project can involve
Review the component drawing, gear geometry, material, tolerances, quantity and inspection requirements.
CNC turning and milling support bores, hubs, shafts, keyways, holes and other component features.
Select the right hobbing, shaping, bevel generation, rack cutting, thread milling or specialized gear-cutting process.
Chamfering, deburring and other finishing operations are incorporated to your project requirements.
We work with qualified outside sources for heat-treating processes and metal finishes when they are required.
Verify the gear against drawing, purchase-order and job-specific quality requirements with the appropriate gear and dimensional inspection methods.
A finished, inspected component — ready for your next manufacturing or assembly operation.
Prototype, replacement & production
Our RFQ process supports every stage of a gear program:
Industries served
We manufacture gears and related components for OEM and industrial applications, including:
Recent work includes components for transit-car door systems, mattress-making equipment, motorized blinds, medical-device mechanisms and mining equipment.
Custom gear cutting quotes

Verifying the gear after it is cut
Gear manufacturing does not end when the cutting machine stops. We maintain dedicated inspection equipment and documented inspection procedures for evaluating gear geometry and dimensional requirements to the component, drawing and purchase order.
For each new job, a quality plan is developed around your part, drawing and purchase-order requirements — and followed through production.
