CNC Milling for Precision Custom Parts
CNC milling is a machining process that uses rotating cutting tools to remove material from a fixed workpiece. At 6 CNC, we provide CNC milling for custom parts that require accurate dimensions, clean surface finishes, and reliable repeatability.
We support projects from early prototypes to small-batch production. If your part includes flat surfaces, slots, pockets, or complex contours, CNC milling is often the most efficient way to produce it.
- One-stop solution (machining + finishing)
- Fast turnaround & reliable delivery
- Competitive pricing for low-volume production

CNC Milling That Delivers Consistent Accuracy
Precision matters when parts must fit and function together. We control machining accuracy through stable equipment, proper tooling, and process planning.
6 CNC milling capability: tolerance up to ±0.002 mm .
This level of control helps prevent assembly issues and reduces the need for rework.
We use multi-axis machining centers to reduce repositioning during production. Fewer setups mean fewer alignment errors. Your parts stay consistent from the first piece to the last.
When CNC Milling Is the Right Choice
CNC milling works best for parts that require detailed geometry and surface features.
You should choose milling when your part includes:
- Flat surfaces that must remain parallel or square
- Slots, pockets, or cavities
- Complex outer profiles or contours
- Features on multiple faces
If your part is primarily cylindrical, CNC turning is usually more efficient. If it requires multiple angled surfaces in one setup, 5-axis machining may reduce cost and improve accuracy.
We review your design and recommend the process that fits your part, not just our equipment.
CNC Milling Services for Flexible Production
We provide CNC milling for both prototypes and low-volume production. Our typical production range is 1 to 600 parts, allowing you to test designs without committing to large quantities.
This flexibility reduces your upfront investment and gives you room to improve your design. You can validate fit, function, and performance before scaling production.
For repeat orders, we maintain stable processes to ensure consistent quality across batches.
Materials for CNC Milling
Material selection affects machining time, cost, and final performance. We machine both metals and plastics to match your application.
Common metals include aluminum, stainless steel, titanium, and brass. Aluminum machines quickly and keeps cost lower. Stainless steel offers strength but requires slower cutting speeds.
For plastics, we machine ABS, POM, nylon, and PEEK. These materials are often used for lightweight parts or electrical insulation.
We help you choose the right material based on strength, weight, and operating conditions.
Surface Finish and Functional Performance
Surface quality is not just about appearance. It affects how parts seal, slide, and wear over time.
6 CNC surface finish capability: up to Ra 1.6 .
We control tool paths and cutting conditions to achieve stable finishes.
If your part requires tighter finishes, we can apply secondary processes such as grinding or polishing. This helps meet functional requirements without over-machining the entire part.
CNC Milling for Industrial Applications
Our CNC milling service supports industries that require reliable performance and consistent quality. These include aerospace, medical devices, robotics, electronics, and automotive applications . Each industry has different requirements. Aerospace parts demand tight tolerances. Medical components require smooth surfaces and clean finishes. We adapt our machining approach based on the application.
Lead Time and Production Control
Machining time depends on part complexity, material, and tolerance requirements. We plan production to balance speed and quality. Our facility in Shenzhen allows us to support fast global delivery . For urgent projects, we can prioritize machining to help you meet deadlines. We keep communication clear so you know what to expect at each stage.
A CNC Milling Partner That Helps You Avoid Problems
Many machining issues start at the design stage. Thin walls, deep cavities, and unnecessary tolerances can increase cost and delay production. We review your design before machining begins. This allows us to identify risks early and suggest practical improvements. You get parts that are easier to manufacture, more cost-effective, and more reliable in use.

FAQ About About CNC Milling
What types of parts are best suited for CNC milling?
CNC milling is best for parts with flat surfaces, slots, pockets, and complex contours.
It works well for components that require multiple features on different faces.
Can CNC milling handle complex geometries?
Yes. Multi-axis milling machines can produce complex shapes with high accuracy.
For highly complex parts, 5-axis machining may be recommended.
What affects CNC milling cost?
CNC milling cost drivers: material type, part complexity, tolerance, and machining time.
Complex geometries and tight tolerances increase machining cost.
How accurate is CNC milling?
6 CNC milling tolerance: up to ±0.002 mm .
Actual accuracy depends on material and part design.
Do you support small-batch CNC milling?
Yes. 6 CNC supports production from 1 to 600 parts.
This allows flexible production without large volume commitments.
