Precision Stellite CNC Machining Services
Stellite and other cobalt-based alloys offer exceptional resistance to wear, heat, and corrosion, making them essential for extreme environments. However, their extreme hardness and tendency to work-harden make them notoriously difficult to machine.
AXALLOY is a Shenzhen-based CNC machining partner specializing in complex, high-value components made from difficult-to-machine alloys. We provide international engineering, procurement, and quality teams with a reliable, controlled manufacturing route for Stellite CNC machining, from prototype development through controlled repeat production.

We understand that when it comes to machining Stellite, you aren't looking for the lowest commodity price—you need manufacturability, process control, and absolute quality assurance. We align with the needs of your entire team:
For Engineering
Comprehensive DFM feedback, tolerance reviews, and manufacturing-process development to turn complex Stellite geometries into stable production realities.
For Procurement
A dependable supply chain partner capable of handling everything from high-value prototypes (1–20 parts) to low-volume and batch production (up to 10,000+ parts) with a standard lead time of 10–20 business days.
For Quality
Uncompromising inspection and documentation. We provide full material traceability, First Article Inspection (FAI), and project-specific quality records to mitigate supply risk.
Our Stellite Machining Capabilities
Machining Stellite requires rigid setups, specialized tooling, and advanced machining strategies. AXALLOY utilizes state-of-the-art equipment to achieve critical interfaces and tight geometric tolerances on cobalt alloys.
Multi-Axis CNC Milling
Our 3-axis, 4-axis, and 5-axis milling centers are optimized for the heavy cutting forces required by Stellite.
- Tolerance: Precision dimensional tolerances down to ±0.005 mm.
- Capabilities: Complex contours, pockets, thin walls (down to 0.5 mm), and precision interfaces.
- Capacity: Parts up to 1,000 × 600 × 600 mm (3-axis) and Ø500 × 400 mm (5-axis).
CNC Turning & Mill-Turn
Ideal for Stellite shafts, sleeves, nozzles, and valve components requiring strong feature relationships.
- Configuration: Up to 9-axis control with main spindle, sub-spindle, C-axis, Y-axis, and live tooling.
- Precision: Concentricity down to 0.008 mm and roundness down to 0.005 mm.
- Swiss Turning: Available for miniature, high-precision Stellite pins and medical components (bar capacity up to Ø32 mm).
Wire & Sinker EDM
Because Stellite is highly conductive but extremely hard, Electrical Discharge Machining (EDM) is often the most effective way to create complex internal features without inducing tool wear.
- Wire EDM: Cutting accuracy down to ±0.005 mm for narrow slots and precise profiles. Surface finish down to Ra 0.8 μm.
- Sinker EDM: Perfect for deep cavities, blind features, and sharp internal corners (Minimum R0.05 mm) with finishes down to Ra 0.4 μm.
Precision Grinding
For Stellite components requiring ultra-precise sealing surfaces or bearing fits.
- Types: Surface, cylindrical, and centerless grinding.
- Finish & Accuracy: Flatness down to 0.003 mm and superior surface finishes down to Ra 0.2 μm.
Cobalt Alloys We Machine
In addition to standard Stellite grades, AXALLOY possesses deep expertise in machining a wide range of difficult cobalt-based and specialty alloys, including:
- •Stellite Alloys — Wear and heat-resistant components
- •Cobalt Chrome — Medical and aerospace applications
- •L605 & MP35N — High-strength, corrosion-resistant environments
We evaluate material behavior, geometry, tolerances, surface requirements, and production volume before defining the optimal machining process for your specific grade.
