Case Study: 5-Axis Precision CNC Machining of Aluminum Automation Components in 8 Days
Precision Aluminum Components for Industrial Automation — Shipped in 8 Working Days
The Challenge
A European industrial automation manufacturer needed a batch of complex aluminum housings (Alloy 6061) featuring multiple machined faces, tight bores, and a finish suitable for anodizing. Critical features required tolerances of ±0.01 mm, an aesthetic surface free of machining marks, and delivery within two weeks to keep the customer's assembly line on schedule.
Our Solution
Wishtek's engineering team began with a Design-for-Manufacturing (DFM) review to optimize tool access and reduce the number of setups. The parts were then machined on our 5-axis machining centers (±0.005 mm), allowing multiple faces to be completed in a single setup — improving both accuracy and lead time.
- Material: Aluminum 6061
- Process: 5-axis CNC milling + precision finishing
- Critical tolerance: ±0.01 mm; concentricity ±0.01 mm
- Surface finish: Ra 0.8 μm (fine milling)
- Quality flow: IQC → FAI → IPQC → OQC, verified on a CMM (±0.003 mm)
Key Specifications
| Item | Requirement | Result |
|---|---|---|
| Critical tolerance | ±0.01 mm | Achieved (5-axis) |
| Concentricity | ±0.01 mm | Achieved |
| Surface finish | Ra 0.8 μm | Achieved |
| Quantity | Small batch (10–500 pcs) | Delivered |
| Lead time | ≤ 10 working days | 8 working days |
| Inspection | Dimensional report + MTC | Provided |
The Results
All parts met the ±0.01 mm tolerance on critical features and were shipped in 8 working days — ahead of the customer's assembly deadline. Each shipment included a full dimensional report, Material Test Certificate (MTC), and RoHS documentation, enabling the client to pass incoming inspection without rework.
Why It Worked
- In-house capability: 5-axis machining, turning, and inspection under one roof — no outsourcing of core processes
- Engineering support: DFM feedback at the quotation stage reduced risk before machining began
- Quality assurance: ISO 9001 workflow with CMM verification at ±0.003 mm
- Reliability: 98% on-time delivery rate across our order book
