Frequently Asked Questions (FAQs) for B2B Buyers of computer-aided machining
-
How can international B2B buyers effectively vet suppliers of computer-aided machining (CAM) services?
Due diligence is critical when sourcing CAM suppliers internationally. Start by reviewing supplier certifications (such as ISO 9001 and relevant industry-specific standards) and requesting case studies or references from previous global clients. If possible, conduct a virtual or on-site audit to assess production capabilities, technology, and quality control practices. Verify their experience handling exports and inquire about language capabilities to ensure smooth communication. For buyers in Africa, South America, the Middle East, and Europe, leveraging local trade agencies or chambers of commerce to check reputability can add an additional layer of assurance. -
What levels of product customization are typically available in computer-aided machining, and what should buyers clarify at the RFQ stage?
CAM enables high levels of customization across material types, tolerances, finishes, and batch sizes.
