How do I get a quote for CNC machined parts?
Upload your 3D CAD file (STEP or IGES preferred) through the online quote page, then select material, quantity, tolerance requirements, and surface finish. Most quotes are returned within 24 hours, and an engineer reviews every order for manufacturability before production begins.
What materials do you machine?
Common metals include aluminum (6061, 7075), stainless steel (303, 304, 316), brass, copper, mild steel, and titanium. Machinable plastics include ABS, POM (Delrin), nylon, PC, PMMA, PTFE, and PEEK. If a specific alloy or temper is not listed on the quote page, submit the request for manual review and the sourcing team will confirm availability and price.
How does PCBgogo ensure the precision and quality of machined parts?
We use advanced CNC machines, precision inspection equipment, CMM measurement technology, comprehensive quality control measures, and a highly skilled team to ensure that every part meets strict standards. Our factory is certified to IATF 16949 and ISO 9001, which reflects our commitment to quality.
Do you offer prototyping services?
Absolutely yes. Before mass production, we can produce prototypes based on your drawings and requirements for evaluation and approval. Once the prototypes are approved, we proceed with mass production.
What is your quality control system like?
We have a comprehensive quality control system, with strict oversight from raw material procurement to processing and production, and finally to finished product inspection. We are equipped with over 30 advanced testing devices to ensure part quality meets your requirements.
Do you offer quick-turn CNC machining?
Yes. PCBgogo offers fast lead times on quick-turn parts, and many parts can be delivered within 2 to 5 days. An expedite option is available for time-critical projects, and our team works closely with you to meet your most urgent deadlines. Lead time is confirmed at the quoting stage, so you kn ow the delivery date before production begins.
How long does it take to get a quote, and how is the price calculated?
Quotes are provided within 24 hours. Pricing depends on factors such as material, processing technique, quantity, and delivery time. We offer a reasonable quote based on your specific needs and welcome long-term cooperation, with more favorable prices for large orders.
