Whether it’s a one-off prototype or a batch of components, our milling services ensure consistency and precision throughout the production process.
Multi-Axis Prototyping
When your design includes sweeping contours, deep under-cuts or compound angles, conventional 3-axis machining just won’t cut it.
Our multi-axis prototyping service bridges the gap between CAD and production, turning ambitious concepts into fully-functioning parts within days, not weeks. Whether you’re validating a new product, pitching to investors or solving an urgent engineering headache, we give you tangible, test-ready components on a schedule that keeps innovation moving.
Shaft Machining
Long, slender shafts are notorious for vibration, deflection and inconsistent surface finish. At Sterling Machining we’ve spent two decades refining the techniques, tooling and fixturing that turn these challenges into repeatable, high-quality results, whether you need a single prototype or a full production batch.
