FAQ
Q1: What does the "xl" designation mean for these CNC aluminum parts?
A: The “xl” designation indicates our capability to produce Custom CNC Machined Aluminum Parts with larger dimensions than standard. We can machine parts up to 2 meters in length and 800mm in diameter, with custom fixturing to accommodate oversized workpieces while maintaining precision.
Q2: How do you ensure flatness and straightness on large anodized aluminum parts?
A: We use stress-relieved aluminum stock and precision machining techniques to minimize distortion. Before anodizing, we perform intermediate stress relief if necessary. After anodizing, we re-inspect all critical surfaces and can perform corrective machining if required, ensuring your machined aluminum parts meet flatness and straightness specifications.
Q3: Can you anodize parts with complex internal features or deep cavities?
A: Yes. Our anodizing line is designed to handle complex geometries, with proper racking and agitation to ensure uniform coating thickness even in deep cavities and blind holes. We can also mask specific areas to prevent anodizing where needed.
Q4: What is the typical lead time for large-format anodized aluminum parts?
A: Lead time depends on size and complexity. For prototype XL parts, expect 3-4 weeks including anodizing. Production orders typically require 5-7 weeks after sample approval. We offer expedited services for urgent projects.
Q5: Do you provide any special packaging for oversized CNC aluminum parts?
A: Absolutely. We custom-crate all large components to ensure safe transit. Our packaging includes protective wrapping, foam cushioning, and wooden crates designed to prevent movement and damage during shipping.
