• Experiência em material: Can they work with your desired material (Por exemplo, alumínio, aço inoxidável, plásticos, or exotic alloys like Inconel)? Ask for examples of past projects using the same material—for instance, a shop that regularly machines titanium is better equipped to handle its high strength and heat resistance than one that rarely uses it.
• Ferramentas de software: Do they use modern CAD/CAM software (como solidworks, MasterCam, ou fusão 360)? This ensures accurate design translation and reduces the risk of errors during machining.

3. Check Past Projects and Client References

A reputable CNC provider will be happy to share case studies or client references. When reviewing these:

• Look for projects similar in scope or industry to yours. Por exemplo, if you need custom plastic enclosures for electronics, a shop that’s worked with tech startups on similar enclosures is a better fit.
• Ask about lead times and on-time delivery rates. De acordo com um 2024 survey by the Australian Manufacturing Technology Institute (AMTI), the average lead time for CNC parts in Australia is 2–4 weeks for standard orders, but this can vary by complexity. A provider with a 95%+ on-time delivery rate is more likely to meet your deadlines.
• Contact references to ask about communication: Did the shop keep them updated on project progress? Did they address issues quickly? Poor communication can lead to costly delays, so this is a critical factor.

4. Compare Pricing and Value (Not Just Cost)

While price is important, it shouldn’t be the only factor. A lower quote might mean cutting corners on material quality or precision. Em vez de, focar em valor:

• Does the provider offer additional services like post-machining finishing (Por exemplo, Anodizando, revestimento em pó) ou montagem? This can save you time and money by reducing the need to work with multiple vendors.
• Do they provide design for manufacturability (Dfm) opinião? A good CNC shop will review your CAD designs and suggest tweaks to improve efficiency (Por exemplo, simplifying a geometry to reduce machining time) sem comprometer o desempenho.
