CNC Machining
We finish what we start.
At One-Off Castings, we specialize in more than just metal pouring—we finish what we start. Our in-house CNC machining department allows us to take your project from casting to fully machined final part with unmatched accuracy and attention to detail. Whether it's a single prototype, replacement component, or short-run production, we ensure every part is dimensionally precise, reliable, and ready for its real-world application.

Why CNC Machining Matters
A quality casting still needs final precision.
CNC machining is critical in turning a quality casting into a functioning component. Even the best castings require final precision touches that only machining can provide. Our machining team works directly from your CAD model or reverse-engineered scan to ensure a seamless fit, tight tolerances, and optimal performance.
- Tight tolerance machining for critical dimensions
- Surface finishing for sealing and mating components
- Complex geometry features that cannot be cast
- Threading, boring, and cleanup post heat-treatment
- Full integration with our casting process to reduce lead time and cost
Machining Capabilities
Built for one-offs.
Unlike volume production shops, our CNC department is optimized for flexibility, speed, and high-mix, low-volume work.
- 3-axis and 4-axis milling
- Horizontal and vertical turning
- Boring, facing, threading, and grooving
- Complex toolpaths from CAD or reverse-engineering
- Post-processing cleanup for heat-treated components
