Complex Mill-Turn Parts
Precision Machining for Complex Mill-Turn Components
AXALLOY Precision is a Shenzhen-based CNC machining partner specializing in complex mill-turn parts made from difficult-to-machine alloys. We deliver high-value, tight-tolerance components with fewer setups, stronger feature relationships, and full traceability — exactly what customers in aerospace, medical devices, semiconductor equipment, energy, and precision industrial markets demand.
Request a Capability ReviewWhy Complex Mill-Turn Parts Matter to Us
Our mill-turn expertise combines the best of multi-axis milling and turning in a single setup. This approach is ideal for parts that require:
- Simultaneous or sequential machining of complex external and internal geometries
- Thin walls (as low as 0.5 mm) with no distortion
- Critical interfaces, tight geometric tolerances, and demanding surface finishes
- High positional accuracy and repeatability across multiple features
