CNC milling refers to a machining tool used to cut bits of a solid block to produce their accurate parts.
TUOWEI Precision delivers expert CNC milling services for custom metal and plastic components, providing rapid prototyping and efficient production solutions for high-precision parts with quick turnaround.
TUOWEI delivers precision CNC milling through a network of advanced facilities equipped with state-of-the-art technology. Our capabilities cover 3-axis, 4-axis, 5-axis, and right-angle milling, allowing us to handle everything from simple cuts to highly complex geometries with speed and accuracy.
We provide rapid turnaround, competitive pricing, and expert design-for-manufacturability support across metals, plastics, and composites. Whether you need prototypes or production parts, TUOWEI ensures quality, reliability, and transparent costs with no hidden fees on standard shipments.

Controlled by G-Code generated through CAM software, CNC mills direct the cutting tool’s movements, speeds, depths, and feed rates to achieve the desired shape. Depending on the number of axes, the process can handle anything from simple profiles to complex geometries. Unlike CNC routers, which keep the workpiece fixed, CNC milling may move both the cutting head and the workpiece, offering greater versatility. This makes CNC milling a preferred solution for producing high-precision parts across industries.

These are some surface finishing techniques that can be applied to ensure high-quality results:
Sanding smooths the surface, removing burrs and imperfections, while preparing the material for painting or coating.
Brushing involves using a rotating wire brush to create a uniform textured surface, often used for stainless steel or aluminum.
This technique uses electrical currents to polish metal surfaces, enhancing both the appearance and corrosion resistance of stainless steel components.
Chemical polishing removes surface irregularities using chemicals, offering a smooth finish on complex geometries that are difficult to reach mechanically.
Vibratory finishing involves placing parts in a vibrating container with abrasive media to smooth out rough surfaces, ideal for small and intricate parts.
Thermal spraying coats a surface with a layer of melted material, improving surface hardness, corrosion resistance, and wear resistance
Engineers and leading manufacturers trust TUOWEI for fast iterations and durable, high-performance parts. Whether for prototyping or full-scale production, our extensive material selection ensures precision, strength, and reliability for any CNC machining project.

At TUOWEI, the CNC milling process begins with understanding the client’s requirements. Our team of experts collaborates with clients to ensure that every detail of the design is accurate and feasible for manufacturing. Here’s a step-by-step breakdown of the process:
The process begins with a 3D CAD (Computer-Aided Design) model of the part or component. This model is shared with our team, where it is analyzed for manufacturability, ensuring that all tolerances and specifications are within achievable limits.
Once the design is finalized, our team uses advanced CAM (Computer-Aided Manufacturing) software to generate a tool path. This step ensures that the CNC machine knows the precise movements required to cut the material.
The material, whether it’s titanium, aluminum, or plastic, is securely placed in the CNC milling machine. Tuowei uses high-quality raw materials to ensure that every part meets the required mechanical properties and surface finish.
The CNC machine begins the milling operation. The cutting tools move along the designated axes (usually X, Y, and Z) to remove material from the workpiece. With our multi-axis CNC machines, we can achieve highly complex geometries in a single setup, reducing the need for rework or additional steps.
After machining, each part is thoroughly inspected for dimensional accuracy, surface finish, and overall quality. Our quality control team uses advanced measuring instruments like CMM (Coordinate Measuring Machines) to ensure each part meets precise specifications.
Depending on the requirements, additional processes like polishing, anodizing, or coating may be applied to achieve the final look and functionality of the part.
The precision of the CNC milling process ensures that even the most intricate parts are produced to tight tolerances, with accuracy levels typically within ±0.005 mm. This allows us to produce high-quality components that meet stringent industry standards.
TUOWEI invests in state-of-the-art CNC milling technology to ensure optimal performance and the highest quality results. Here are some of the key technologies used in our CNC milling services:
We use multi-axis CNC milling machines, including 3-axis, 4-axis, and 5-axis machines, to produce highly complex parts with intricate features. The 5-axis capability allows for greater flexibility, enabling us to work on more challenging geometries and reduce setup time.
Our high-speed spindles allow for faster cutting speeds and improved surface finishes. With speeds up to 40,000 RPM, we can efficiently machine materials, such as titanium and aluminum, with precision.
Live tooling allows us to perform multiple operations, such as drilling, tapping, and milling, without changing tools. This reduces cycle times and enhances productivity.
Our CNC machines are equipped with automated tool changers, ensuring smooth transitions between different tools, increasing operational efficiency and reducing machine downtime.
We use industry-leading CAD and CAM software to create tool paths and simulate the machining process. This ensures that every part is machined to perfection before the actual cutting begins.
