Frequent Asked Questions
1.What materials can be processed with your CNC milling services?
We process a wide range of metals and plastics, including Aluminum (e.g., 6061, 7075), Stainless Steel (304, 316), Titanium, Brass, Copper, as well as engineering plastics like POM, ABS, Nylon, and PEEK.
2. What is the maximum precision and tolerance level you can achieve for custom milling parts?
Utilizing advanced 3-axis, 4-axis, and 5-axis CNC machining centers along with high-precision CMM inspection equipment, we can strictly control tolerances within ±0.005 mm to ±0.01 mm (depending on part geometry and material specifications).
3. What surface finishing options do you offer for CNC milled components?
We provide comprehensive post-processing and surface treatments to meet structural and aesthetic requirements, including As-Machined, Anodizing (Type II & Type III Hardcoat), Powder Coating, Passivation, Electroplating, Bead Blasting, Polishing, and Laser Engraving.
4. How do you handle quality control and inspection before shipment?
Every project undergoes rigorous quality management protocols, including First Article Inspection (FAI), in-process dimensional checking, and 100% final inspection using CMM, optical comparators, and surface roughness testers. Full inspection reports and material test certificates (MTC) are provided prior to dispatch.
5. How can I get a quote, and what is the typical lead time for custom prototypes and mass production?
Simply upload your 3D/2D CAD files (STEP, IGES, SolidWorks, or PDF) through our contact form. We usually provide a detailed quote and DFM analysis within 24 hours. Prototypes typically take 3–7 business days, while low-to-high volume production runs usually range from 1 to 3 weeks.
