Frequently Asked Questions (FAQs)

What types of materials can be used for CNC machining in Chinese factories?

You can work with a wide range of materials, including aluminum (e.g., AL 6061-T6, 6063, 7075), stainless steel (e.g., 303, 304, 316L), copper, iron (e.g., 4140, Q235), titanium, and various plastics like PEEK, Nylon, and PMMA. This versatility allows you to choose the best material for your specific application.

How do I ensure the quality and accuracy of CNC machined parts?

To ensure high quality and accuracy, it’s crucial to receive and approve samples before mass production. Chinese factories often use advanced measuring tools like 2D and 3D coordinate measuring machines, altimeters, and micrometers to maintain tight tolerances. For example, linear tolerance can be within ±0.02mm, and angle tolerance within ±1°.

What is the typical production timeline for CNC machined parts in China?

The production timeline can vary, but generally, you can expect around 3 days for in-stock items after payment and about 20-25 days for mass production after receiving the deposit. This timeline can depend on the complexity of the parts and the quantity ordered.

Do Chinese CNC machining factories support additional services like surface treatment and engraving?

Yes, many Chinese CNC machining factories offer a variety of additional services. These include surface treatments such as anodizing, electroplating, PVD, nickel plating, sandblasting, and polishing. They also support engraving methods like laser engraving, etching, and pad printing to meet your specific requirements.

How do I pay for CNC machining services in China, and what are the common payment terms?

For small transactions, you can often use PayPal, though factories may add a transaction fee. For larger orders, typically over $500, factories usually require a wire transfer from your bank. Half of the payment is due when you submit the purchase order, and the other half is due when the goods are shipped. This ensures both parties are protected throughout the transaction process.
