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.
At TUOWEI Precision, we transform straightforward 3-axis operations to advanced 5-axis projects, our services deliver unmatched accuracy, efficiency, and craftsmanship for custom parts of any complexity.
Our 3-axis CNC milling ensures affordable, precise production for simple geometries, maintaining excellent quality consistently.
TUOWEI’s 4-axis milling enables versatile, multi-sided machining, simplifying production while delivering outstanding precision and flexibility.
For intricate, complex designs, our 5-axis CNC milling achieves unmatched accuracy, handling challenging geometries easily.
TUOWEI Precision ensures accuracy with strict CNC milling tolerance standards, delivering consistent, high-quality parts every time. Our standard tolerances follow ISO 2768-m for metals and ISO 2768-c for plastics, guaranteeing reliable functionality and precise performance across all projects.

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.

What is Tool Offset in CNC Milling?
In CNC milling, a tool offset is the adjustment applied to compensate for the cutting tool’s length and diameter. This calibration ensures the tool cuts precisely in relation to the workpiece, preventing dimensional errors. By setting accurate offsets, machinists establish the correct machining start point, guaranteeing that parts meet exact specifications. Proper tool offsets are essential for maintaining accuracy, consistency, and high-quality results throughout the milling process.
What’s the difference between CNC milling and CNC routing?
While both use computer-controlled cutting, they serve different purposes.
CNC Milling: Built for high-precision machining of metals and hard materials, capable of producing intricate parts with tight tolerances.
CNC Routing: Designed for softer materials like wood, plastics, and composites. Routers operate at higher speeds and are better for cutting large sheets where ultra-high precision isn’t required.
In short, milling prioritizes accuracy and complexity, while routing emphasizes speed and large-format material handling.
What’s the difference between CNC milling and CNC turning?
Both CNC milling and turning are subtractive processes, but they differ in operation.
CNC Milling: The workpiece remains stationary while the cutting tool moves across multiple axes, making it ideal for complex parts with slots, contours, and holes.CNC Turning: The workpiece rotates while the tool stays fixed, making it more efficient for cylindrical components like shafts, bolts, and rings. Milling is best for complex shapes, while turning excels in producing round parts quickly and efficiently.
