CNC Turning
Tight-tolerance turning for shafts, housings, and custom fittings.
CNC Turning Services
Tight-tolerance turning for shafts, housings, and custom fittings. At CG Model Tek, our precision CNC lathes and turning centers produce cylindrical components with exceptional roundness, concentricity, and surface finish. From simple shafts to complex multi-diameter parts with internal features, we deliver turning solutions for aerospace, tooling, and prototype applications.
