Precision Inconel 718 Milling Services | AXALLOY Precision
Complex Geometry. Tight Tolerances. Controlled Processes.
Inconel 718 is notorious for its extreme toughness, rapid work-hardening behavior, and high cutting temperatures. Machining this nickel-based superalloy requires more than just standard equipment—it demands rigid machine setups, optimized toolpaths, specialized tooling, and strict process control.
At AXALLOY Precision, located in Shenzhen, we specialize in Inconel 718 milling for international engineering, procurement, and quality teams. From high-value prototype development to controlled, low-volume repeat production, we deliver complex components that meet your exact specifications without compromising on manufacturability or quality documentation.
Our Inconel 718 Milling Capabilities
We utilize advanced multi-axis CNC machining centers to produce complex contours, deep pockets, thin walls, and precision interfaces in Inconel 718. Before a single chip is cut, our engineering team evaluates part geometry, tolerances, and surface requirements to define the most stable manufacturing process.
Multi-Axis CNC Milling
- 5-Axis CNC Milling:Ideal for complex impellers, blades, and aerospace components requiring continuous machining. (Max Part Size: Ø500 × 400 mm)
- 4-Axis CNC Milling:Perfect for manifolds and multi-sided housings requiring fewer setups. (Max Part Size: Ø500 × 800 mm)
- 3-Axis CNC Milling:For rigid, high-precision structural components and plates. (Max Part Size: 1,000 × 600 × 600 mm)
Complementary Processes for Difficult Features
When Inconel 718 geometry exceeds the limits of traditional milling (such as sharp internal corners or extreme depth-to-diameter ratios), we integrate in-house special processes:
- Wire EDM & Sinker EDM:For narrow slots (down to 0.15mm), deep cavities, and sharp internal corners (down to R0.05 mm) with surface finishes down to Ra 0.4 μm.
- Precision Grinding:Achieving extreme flatness (0.003 mm) and superior surface finishes (Ra 0.2 μm) on critical sealing faces and bearing fits.
