We provide CNC milling services for custom metal and plastic parts, from prototyping to production, with engineering review, controlled quality, and support for finishing and secondary processes.
CNC milling is a machining process that uses computer-controlled rotating cutting tools to remove material from a solid block and form precise custom parts. It is commonly used for metal and plastic components that require accuracy and repeatability.
• CAD model defines the part geometry.
• Toolpaths are programmed for controlled cutting.
• Rotating tools remove material to form features and surfaces.
• Suitable for complex shapes and tight tolerances.
CNC milling is best suited for parts that require precise features, flat surfaces, and complex geometries. It is widely used for both functional prototypes and production components.
Multiple faces, pockets, slots, and detailed geometries that require precise machining.
Parts that need tight tolerances, accurate positioning, and consistent repeatability.
Low-volume or custom parts that require flexibility and fast iteration.
Common materials include aluminum, steel, stainless steel, and engineering plastics.
From complex machining to production support, we help turn your drawings into accurate and repeatable parts.
Machine complex geometries, multi-face parts, and detailed features with fewer setups.
Maintain accurate dimensions and consistent results for precision-critical components.
Support one-off prototypes, small batches, and repeat production with stable process control.
Add anodizing, coating, deburring, tapping, and assembly support in one workflow.
Quick turnaround • CAD/CAM programming • In-process inspection • Wide material support

We support CNC milling and surface finishing in one workflow to match part function, appearance goals, and project requirements.
Used for aluminum parts that need improved corrosion resistance and a cleaner finished appearance.
Creates a uniform matte texture and improves overall surface consistency.
Suitable for selected parts that need added corrosion resistance, conductivity, or appearance control.
Used to add surface protection, color consistency, and a more durable coated layer.
Used when a directional grain and a more controlled metal appearance are required.
Suitable for parts that require a smoother surface and a cleaner cosmetic finish.
The best finishing option depends on the material, part function, surface expectation, and end-use environment.
CNC milling can support different project stages, from prototype validation to production parts that require stable machining and controlled quality.
Suitable for product development, design validation, and early functional testing.
A good fit for pilot runs, low-volume orders, and early production demand.
Suitable for production components that require stable dimensions, repeatable quality, and application-matched materials.
Suitable for parts that need CNC milling together with finishing, sheet metal fabrication, or assembly support.
If your part requires both machining support and engineering review, we can help evaluate whether CNC milling is the right fit for the project.
We review each project before quotation to ensure the machining approach, material choice, and production plan are clear from the start.
Upload your drawing, 3D file, material, quantity, and any specific requirements.
Once approved, production and inspection proceed based on the confirmed plan.
Here are some common questions about our CNC milling service, including materials, tolerances, lead time, and project support.
We usually need a 2D drawing or 3D CAD file for quotation. Common formats include STEP, STP, IGES, PDF, and DWG. If you also have material, surface finish, or quantity requirements, please send them together.
We machine a range of common metals and plastics for custom parts. Typical materials include aluminum, stainless steel, steel, brass, copper, titanium, ABS, POM, nylon, acrylic, PTFE, and PC. If you need a specific grade, our team can review it based on your project.
Yes. We support prototype machining, small batch orders, and production work depending on part requirements and project volume.
Yes. We can coordinate surface finishing such as anodizing, powder coating, painting, and other selected processes based on project needs.
Typical CNC milling tolerances depend on part geometry, material, size, and feature requirements. For standard projects, tolerances are commonly controlled within ±0.005 in. (±0.127 mm). For parts with tighter requirements, closer tolerances can be reviewed based on the drawing, machining process, and inspection method.
Yes. We can support projects that require CNC milling together with sheet metal fabrication, finishing, and related secondary processes.
Lead time depends on part geometry, material, quantity, finishing requirements, and inspection scope. Our team confirms the schedule after engineering review.
The cost of CNC milling depends on part geometry, material, tolerance requirements, quantity, machining time, and any finishing or inspection needs. Simple parts with standard materials are usually more cost-effective, while complex features, tighter tolerances, and secondary processes can increase the cost. For an accurate price, please send us your drawing or CAD file so our team can review the project and provide a quotation.
