A European startup specializing in advanced robotics research approached us with a critical goal: reducing the weight of their next-generation robot arm. Recognizing that magnesium offers a superior strength-to-weight ratio compared to aluminum, they sought our expertise in Magnesium CNC Machining to fabricate a custom housing that maximizes agility without compromising durability.

Part type: Robot Arm Shell

Material: Magnesium Alloy AZ31B

Dimensional tolerance: ±0.1 mm

Quantity: 50 pcs

Lead Time: 20 day

Magnesium alloy CNC machining comes with specific challenges: its low hardness makes it prone to tool adhesion and workpiece deformation during clamping. The fine, flammable chips require specialized chip removal systems to avoid fire risks.

Machining magnesium requires strict adherence to safety protocols. At XINGDA CNC, we eliminate the risks of flammability and deformation through a controlled manufacturing process:

• Coolant Strategy: We utilize specialized mineral-oil-based coolants to dissipate heat effectively and prevent hydrogen generation, ensuring a 100% safe machining environment.
• Tooling Optimization: Our engineers select high-polished, uncoated carbide tools with specific geometries to ensure rapid chip evacuation and minimize friction heat.
• Chip Management: We adhere to a “heavy chip load” strategy. By avoiding dwelling and maintaining consistent feed rates, we generate thicker chips that carry heat away from the part, preventing ignition risks associated with fine dust.

With our professional one-stop CNC machining services and strict quality assurance, we deliver international-standard quality at the speed of the Greater Bay Area supply chain. Need your prototype finished in as fast as 5 days? Let’s discuss your specific requirements—contact us now.
