Machining Service
CNC Milling involves the elimination of metal using a rotary cutter or other rotating cutting tool.
With precise machinery and a diverse range of tooling options, it is possible to cut nearly any
material with tolerances as tight as a few thousandths of an inch or even less.
Product Details
CNC milling machines are capable of cutting a wide range of materials, including aluminum,
bronze, copper, ceramics, plywood, various steel alloys, stone, wood, zinc, and various
engineering materials.
This versatility makes them an excellent choice for crafting prototypes during product
development.
Furthermore, CNC milling allows for precise and rapid adjustments until the desired final
product is achieved.
| Common Materials for CNC Machining | |
| Material | Properties |
| Aluminum | 2024: Good fatigue resistance and strength; excellent toughness at moderate to high strength levels; improved fracture toughness |
| 6061: Excellent machinability, low cost, and versatility | |
| 7075: High strength, hardness, low weight, and heat tolerance | |
| Stainless Steel | Excellent machinability and outstanding uniformity; good workability and weldability, high ductility and formability |
| Steel Alloy | Mix of chromium, molybdenum, and manganese yields toughness, good torsional and fatigue strength |
| Brass | Versatile and highly attractive copper/zinc alloy with warm yellow color accommodates severe forming/drawing |
| Titanium | Excellent strength to weight ratio, used in aerospace, automotive, and medical industries |
| Copper | High ductility and high electrical and thermal conductivity; develops attractive blue-green surface patina over time |
| ABS | Excellent impact resistance, good mechanical properties, susceptible to solvents |
| Nylon | Excellent mechanical properties, high toughness, poor moisture resistance |
| POM | High stiffness, excellent thermal & electrical properties, relatively brittle |
CNC Machining Tolerances
Tolerances are not standardized across all processes and materials.
The final tolerances on your part depend on various factors, such as part size, design complexity,
the number and size of features, materials used, surface finish, and the manufacturing process
employed.
Once your order is confirmed, we conduct a Design for Manufacturing review to identify areas that
may need modification for better manufacturability.
It's helpful if you can specify which areas in your design have critical tolerances that must be met
and which can be adjusted, if necessary, to optimize production time and cost.
| CNC Milling Tolerances | ||
| Limits for nominal size | Plastics | Metals |
| 0.5mm* to 3mm | ±0.1mm | ±0.05mm |
| Over 3mm to 6mm | ±0.1mm | ±0.05mm |
| Over 6mm to 30mm | ±0.2mm | ±0.10mm |
| Over 30mm to 120mm | ±0.3mm | ±0.15mm |
| Over 120mm to 400mm | ±0.5mm | ±0.20mm |
| Over 400mm to 1000mm | ±0.8mm | ±0.30mm |
| Over 1000mm to 2000mm | ±1.2mm | ±0.50mm |
| Over 2000mm to 4000mm | ±2.0mm | |
| *Please clearly indicate tolerances for nominal sizes, below 0.5mm on your technical drawing. | ||
Specialist industries
CNC machining is a highly utilized subtractive manufacturing process employed across a
multitude of industries.
It plays a crucial role in aerospace, automotive, aviation, transportation, and numerous other
integral sectors.
For instance, in the aerospace industry, the production of airplane components demands an
exceptional level of precision to ensure the seamless functionality of the entire aircraft.

FAQ's
1. Can make design drawings for me?
While we do not offer standalone product design services, we do provide Design for Manufacturing
(DFM) reviews for all approved orders.
This means we collaborate with our clients to optimize their 2D and 3D drawings, enhancing
manufacturability, resolving design issues, and reducing production expenses.
Learn more about preparing your CAD drawings for manufacturing.
2. Accepted Design File Formats for Quoting
To ensure accurate and prompt quotations, we exclusively accept 3D CAD files in STL, STEP,
or IGES formats.
For 2D drawings with reference dimensions, please provide them in PDF format.
Complete manufacturing information should be included in this technical documentation.
Please note that informal communication via SMS, Skype, email, etc., will not be considered
acceptable for manufacturing purposes.
3. Ensuring Design Confidentiality
Rest assured, we are committed to maintaining the confidentiality of your designs.
We are more than willing to sign and uphold any non-disclosure or confidentiality agreement
you require.
Furthermore, our factory strictly enforces a "no photographs" policy for any customer's product
without explicit permission.
Our reputation is built on years of experience, working with countless unique designs, and
safeguarding proprietary information from third-party disclosure.
Your design's confidentiality is our priority.
4. Price Comparison with Other Suppliers
When it comes to pricing, making direct comparisons can be challenging.
However, as a general guideline, our prices for plastic injection mold tools and CNC
machined/turned parts are typically 25-45% lower than those of suppliers in North America
and Europe.
In contrast to Chinese suppliers, we prioritize delivering the utmost quality, swift response times,
and professional outcomes, rather than engaging in a price-driven competition.
