Frequently Asked Questions (FAQs)

What is CNC Machining and how does it work in Chinese factories?

CNC machining in Chinese factories involves using computerized controls and automated machinery to create precise and intricate parts. The process starts with creating a 3D digital model using CAD software, which is then converted into machine-readable code by CAM software. This code guides the CNC machine to cut and shape the material accurately. The machine operator sets up the machine, secures the raw material, and the CNC machine executes the programmed instructions to produce the desired part.

Is there a quality difference between parts made in the US and those made in China?

No, there is no inherent quality difference between parts made in the US and those made in China, especially when working with reputable suppliers. Companies like Xometry ensure that all parts, regardless of the country of origin, meet the same manufacturing standards. This means you can expect high-quality parts whether they are made in the US or China.

How can I ensure quality control when working with a Chinese machining factory?

To ensure quality control, it’s crucial to work with a reliable and experienced precision manufacturing company. You should hire a trusted local agent to conduct in-person inspections, and the factory should follow strict quality control measures, such as those outlined in Xometry’s Inspection & Sampling Plan. Regular communication and visits to the factory can also help in understanding the manufacturing process and addressing any issues promptly.

What are the common finishing processes available for CNC machined parts in China?

In China, several finishing processes are available for CNC machined parts. These include a standard finish (as-milled), bead blasting for a smooth matte appearance, tumbling to remove sharp edges and burrs, and anodizing (Type II or Type III) for corrosion-resistant and wear-resistant finishes. These processes can enhance the appearance and functionality of the machined parts.

How do I handle duties and tariffs when importing CNC machined parts from China?

When importing CNC machined parts from China, duties and tariffs are typically included in the part price by the supplier. This means you do not have to pay any additional fees separately. However, it’s always a good idea to clarify this with your supplier to avoid any unexpected costs. Companies like Xometry include these costs in the initial quote to make the process smoother for you.
