CNC machining allows us to deliver tight-tolerance parts with consistency across every run. At Principal Manufacturing Corporation, we support a wide range of applications using in-house equipment that includes mills, lathes, EDM, plasma cutters, and waterjets. Our process is built for dimensional accuracy, speed, and repeatability.
Full-Service Machining Capabilities
CNC machining uses programmed instructions to control cutting tools, eliminating variation and reducing manual setup. We provide:
- Milling for flat surfaces, pockets, and threaded holes
- Turning for shafts, screws, and concentric components
- EDM (electrical discharge machining) for sharp angles and fine features
- Plasma cutting for steel, aluminum, brass, and copper
- Waterjet cutting for materials sensitive to heat or requiring clean edges
These services support everything from prototypes to production-scale components.
Integrated With Tooling and Production
Machining is only part of the picture. Our in-house operations also include fine blanking, custom metal stamping services, plastic injection overmolding, and tooling design. Keeping these processes under one roof helps us reduce lead times, improve communication, and maintain tight control over part quality.
Certified and Equipped for Precision
Principal Manufacturing is certified to IATF 16949:2016 and ISO 14001:2015. Our CNC team works alongside engineers and quality staff to meet specifications with confidence, backed by state-of-the-art inspection systems.
