CNC Machining
Our CNC machining services combine advanced technology with decades of expertise to produce complex metal components with tight tolerances. We utilize modern CNC lathes and machining centers capable of handling workpieces up to 21" diameter with Fanuc controls for precision. This service supports both prototyping and production for industrial clients requiring accurate, repeatable results.
Gear Hobbing
Specializing in gear hobbing since 1964, we produce spur and helical gears from 1" to 36" diameter with capacities ranging from 2 Pitch to 32 Pitch. Our equipment includes multiple gear hobbers with crown hobbing capabilities up to 26" diameter, serving clients needing precision gears for industrial machinery and specialized applications.
Spline Broaching
With a 72" horizontal broaching capacity and National Broach Red Ring systems, we create precision splines and keyways up to 1-1/2" wide. This service supports manufacturers requiring accurate internal and external spline forms for power transmission components, with capabilities for both prototype and production quantities.
Prototype Development
We offer prototype development services for clients testing new designs before full production. Our machining capabilities allow creation of single components or small batches with complete specifications, utilizing our full range of equipment including CNC mills, lathes, and specialized gear cutting systems to validate designs before scaling up.
Gear Shaving
Our gear shaving service improves tooth form accuracy and surface finish on straight, crown, and taper gears up to 18" diameter. This precision finishing process ensures optimal meshing characteristics and extends component lifespan, serving clients with demanding applications requiring enhanced gear performance.
