Based on our past CNC machining orders, over 90% are completed within about 7 days. Simple parts can be finished in as little as 2 days, while complex or large parts may take 15 days or more. Quantity also affects the lead time. Through our global CNC machining network, we can produce your parts from

First of all, make sure your parts are designed to be CNC machining–friendly. For example, avoid features such as sharp corners, deep pockets, and thin walls. Secondly, choose the right CNC machining company for your project. For simple and small parts, you can easily find small CNC machine shops that offer competitive pricing. However, if

Our production engineers personally review every RFQ we receive to ensure that the material selection and machining costs are accurately evaluated. In contrast, most online CNC quotation systems are still not accurate enough to reflect real manufacturing conditions. (Read more in our case study.)

6CProto is recognized as one of the leading CNC machining companies in China, known for its quality, speed, and customer support. With our high-precision CNC equipment, we can typically achieve tolerances of ±0.02 mm and, in some cases, as tight as ±0.01 mm. Please note that tighter tolerances may increase production costs.

6CProto operates two CNC machining facilities equipped with over 60 CNC milling and turning machines. With more than 40 experienced technical experts, we are capable of producing up to 5,000 different types of CNC machined parts in-house. In addition, through our verified manufacturing partners within our network, we can handle extra CNC machining orders without

As soon as we receive your RFQ, our engineers will review your CAD files and provide design feedback and optimization suggestions for CNC machining if needed. This helps ensure better part quality and identifies opportunities to reduce CNC machining costs, which can lower the unit price.

Prices start at around $50, but vary depending on part complexity, quantity, and lead time. The best way to get an accurate estimate is to submit a 3D CAD model and receive an interactive quote along with design-for-manufacturability (DFM) feedback. Thanks to our proprietary software and automated fixturing processes, there are no upfront non-recurring engineering

CNC machining is generally more cost-effective for simple parts. While complex geometries can be produced, they often require multi-axis setups, which increase both time and cost. Tool access can limit design flexibility, as the size and angle of cutting tools affect reach. High setup costs can raise per-part prices for small batches. Additionally, as a

CNC machining offers key advantages over 3D printing, injection molding, and laser cutting: It is fast and cost-effective for simple parts, such as base plates with holes or grooves. CNC machines can achieve tight tolerances of ±0.01 mm and deliver smooth surface finishes down to Ra 0.8, making them ideal for painting or anodizing. They

CNC (Computer Numerical Control) machining is a precise and efficient manufacturing process that uses automated cutting tools to shape metal or plastic parts. Depending on part complexity, we use 3-axis, 4-axis, or 5-axis milling machines, lathes, or routers. Once we receive your 3D CAD model, our skilled machinists program optimized tool paths to reduce costs
