From digital concept to physical reality—fast. That was the requirement for this custom robotics project. Our client required a functional CNC machined aluminum 7075 prototype to validate their robot’s walking mechanism before committing to expensive molds.

Why Aluminum 7075? Because the part serves as the primary load-bearing structure (the femur) and requires steel-like strength.

Part type: Upper Leg Link

Material: 7075-T6 aluminum

Dimensional tolerance: ±0.05 mm

Surface Finish: Black Anodizing

Batch quantity: 5 units

Delivery Time: 7 day

While Aluminum 6061 is the standard for general prototyping, CNC machined aluminum 7075 prototypes are the preferred choice for high-performance applications.:

High Strength: 7075 has a tensile strength of ~572 MPa (double that of 6061).
Fatigue Resistance: Ideal for parts under cyclic loading (like drone arms or suspension parts).
Machinability: Despite its hardness, 7075 chips break easily, allowing for excellent surface finishes when machined correctly.
