5 - Axis CNC Aluminum Machining Parts

Product Overview

Unlike traditional 3-axis machining, 5-axis technology allows simultaneous movement of the workpiece along five axes, enabling undercuts, compound angles, and complex contours in a single setup. Our process specializes in aluminum alloys such as 6061-T6, 7075-T6, and 2024-T3, delivering parts that meet ISO 2768-1 and AS9100 standards for aerospace and high-performance applications. From lightweight aerospace structures to precision robotics components, these machined parts balance strength, weight reduction, and geometric complexity.

Product Features

Precision: 5-axis machining achieves positional accuracy of ±0.002 mm and repeatability of ±0.001 mm, with contouring accuracy of 0.01 mm/m for complex curved surfaces.

Material Optimization: 6061-T6 aluminum parts offer a tensile strength of 310 MPa and density of 2.7 g/cm³, providing an ideal strength-to-weight ratio for weight-critical applications.

Production Efficiency: Simultaneous 5-axis movement reduces setup times by 60–70% compared to 3-axis machining, with high-speed spindles (15,000 RPM) enabling material removal rates up to 500 cm³/min.

Complex Geometry Capability: Machines with AC axis rotation (±120° tilt) can produce undercuts up to 90° and compound angles with 0.001° angular accuracy, eliminating the need for multiple setups.

Applications

These advanced machined parts serve cutting-edge industries:

Aerospace: Wing spars, fuselage brackets, and engine components from 7075-T6, meeting aerospace material specifications (AMS 4045).

Automotive Racing: Lightweight suspension components and intake manifolds from 6061-T6, reducing unsprung weight by 15–20% compared to steel alternatives.

Robotics & Automation: Precision linkages and end-effector components with tight tolerance fits, ensuring repeatable motion control (±0.01 mm).

Medical Devices: CT scanner frames and surgical robot arms from 6061-T6, featuring radiopacity and biocompatibility with anodized finishes.

FAQ

Q: What is the maximum part size you can produce with 5-axis machining?

A: Our large-format 5-axis centers accommodate workpieces up to 1,200 mm × 800 mm × 600 mm, with smaller machines handling micro-components as small as 5 mm × 5 mm.

Q: How does 5-axis machining improve part quality?

A: Single-setup machining reduces cumulative tolerance errors by 80% compared to multi-setup processes, while shorter tool lengths minimize vibration for better surface finish (Ra 0.8 μm).

Q: What surface finishes are available for aluminum machined parts?

A: Options include Type II anodizing (20–50 μm thickness), hard anodizing (50–100 μm, HRC 50+), and chemical conversion coating (per MIL-DTL-5541) for corrosion resistance and paint adhesion.
