Process: Step-by-Step Magnesium CNC Machining Workflow
The Magnesium CNC Machining Process follows a structured sequence of steps to transform raw magnesium into finished parts. Each stage is optimized to address magnesium’s unique challenges (e.g., flammability, low rigidity) and ensure precision:
- Design & Programming: Engineers create 3D models (using CAD software) and convert them into G-code—detailing tool paths, cutting speeds, and programming parameters to avoid overheating and fire risks.
- Material Preparation: Raw magnesium stock (bars, sheets, or blocks) is cut to size and inspected for purity, ensuring it matches the chosen magnesium alloy specifications.
- Machine Setup: Technicians mount the magnesium onto the CNC machine, calibrate specialized tooling (e.g., heat-resistant end mills), and activate fire-suppression systems as a safety precaution.
- Core Machining Operations: The machine executes specialized techniques for magnesium:
- Cutting: Trimming excess material with moderate feed rates and high coolant flow to manage heat and prevent ignition.
- Drilling: Creating precise holes with peck drilling techniques to clear chips (which are flammable) and reduce friction.
- Milling: Shaping surfaces with low spindle speeds to avoid heat buildup, leveraging magnesium’s lightweight nature to prevent part deformation.
- Inspection: Every part undergoes rigorous measurement using tools like coordinate measuring machines (CMMs) to verify dimensional control and accuracy.
- Finishing: Parts move to surface treatment (covered in Section 5) to enhance corrosion protection and durability.
This workflow ensures a production efficiency rate of 90%—impressive for magnesium, given its safety and machining challenges—and reduces turnaround times for critical components.

| AZ61 Magnesium | Higher strength than AZ31, good machinability | Automotive structural parts, marine components |
| AZ80 Magnesium | High strength, excellent impact resistance | Aerospace brackets, heavy-duty automotive parts |
| AM60 Magnesium | Superior corrosion resistance, good castability | Medical device housings, outdoor equipment |
| AE42 Magnesium | High-temperature stability, creep resistance | Engine components, industrial furnace parts |
| Complementary Metals | Aluminum: Lightweight; Titanium: High-strength; Steel: Durable | Automotive chassis, aerospace parts, industrial tools |

We also provide guidance on material pairing—for example, using AZ31 for lightweight electronics enclosures and AZ80 for high-stress aerospace components.
Surface Treatment: Enhancing Magnesium Part Performance
Magnesium Surface Treatment is a vital post-machining step that improves magnesium parts’ corrosion protection, durability, and aesthetics. Yigu Technology offers a range of finishing options tailored to magnesium’s properties (which are naturally less corrosion-resistant than steel or aluminum):
| Surface Treatment Method | Purpose |
| Anodizing | Creates a hard, porous oxide layer that can be sealed for enhanced corrosion resistance |
| Passivation | Applies a chemical coating (e.g., chromate) to prevent oxidation |
| Plating | Coats with metals like nickel or zinc to boost corrosion resistance and conductivity |
| Coatings | Applies polymer or ceramic layers to provide long-term protection against moisture |
| Polishing | Creates a smooth, reflective finish to improve aesthetics and reduce dirt buildup |
| Blasting | Creates a textured surface for better coating adhesion or grip |
Our processes ensure magnesium surface treatment meets industry standards—for example, ISO 1461 for corrosion resistance and ASTM B893 for anodized magnesium.
