OEM Service Precision CNC Milling Parts Stainless Steel CNC Machining CNC Part Supplier
Our CNC mills, also known as CNC milling machines, have the capability to manufacture parts
in nearly any shape, utilizing a wide range of materials.
We offer cost-effective milling services for various materials, from soft metals like aluminum to
more robust metals like steel, and even plastics such as acetal.
Whether you need a single part, a batch of prototypes, or a complete production order, we have
the expertise to meet your requirements.
Product Details
In custom milling projects, CNC machine shops can work with a variety of metals and plastics,
provided they are suitable for machining.
The prevalent choice for precision CNC machining is aluminum alloys, prized for their natural
corrosion resistance.
Aluminum stands out as a favored material for CNC milling machine prototypes, thanks to its
combination of strength and machinability, enabling the precise fabrication of intricate features
in a single prototype.
Among aluminum alloys, the 6000 series is the most frequently encountered in milling machine
shops. Stainless steel alloys are another common choice due to their resistance to corrosion
and wear.
Additionally, carbon steel, titanium, and nylon—a chemically resistant, robust, durable
thermoplastic—are materials often employed in CNC milling projects.
| 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. | ||
Common Applications of CNC Milling Parts
CNC milling is employed to fabricate products composed of glass, metal, plastic, wood,
and custom-designed components.
Machinists utilize this process to create prototypes and items for various industries,
including aerospace, automotive, hardware startups, manufacturing, medical devices, robotics,
and others.
Company Profile
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. How long does a quotation take?
Typically, we aim to respond to your Request for Quotation (RFQ) within one days after receiving it.
If there is any unexpected delay in providing the quote, we will promptly notify you of the revised
timeline.
3. How can I ensure the confidentiality of my design?
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. How does compare to other suppliers on price?
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.
