The essence of CNC machining, or Computer Numerical Control machining, lies in its subtractive
manufacturing approach, automatically eliminating material from raw stock based on computer
-generated instructions.
Typically, CNC machines fall into two categories: those that maintain the raw stock in a fixed
position while rotating the cutting tool, and those that rotate the raw stock while maneuvering
it against a stationary tool.
Numerous adaptations and hybrid methods exist, enabling certain machines to utilize both
techniques concurrently, facilitating the production of parts with complex features.
Product Details
Stainless steel is highly resistant to corrosion and rust, making it suitable for situations
where a part may be exposed to the elements for a long period of time. Stainless steel is also
fairly malleable and ductile.
| Common Stainless Steel Materials | |
| No. | Properties |
| Stainless steel 304/304L | Stainless steel 304L (CNC) has excellent mechanical properties and good machinability. Resistant to most environments and corrosive media. |
| Stainless steel 316/316L | Stainless steel 316L (CNC) has similar mechanical properties to 304, with higher corrosion and chemical resistance. Ideal for marine applications. |
| Stainless steel 303 | Stainless steel 303 (CNC) has excellent toughness, but lower corrosion resistance than 304. Ideal for high volumes, due to its excellent machinability. |
| Stainless Steel 17-4 PH | Stainless steel 17-4 (CNC) - SAE grade 630 - is a precipitation hardening alloy with good corrosion resistance. Can be hardened up to 44 HRC. |
| Stainless steel 416 | Stainless steel 416 is magnetic and has a high machinability. |
| Stainless steel 2205 Duplex | Stainless steel 2205 Duplex (CNC) is the alloy with the highest strength and hardness. Suitable for applications in severe environments up to 300°C. |
| Stainless steel 420 | Stainless steel 420 provides high strength and corrosion resistance. It is the hardest of all stainless steels when hardened. |
| Stainless steel 440C | Stainless steel 440C has improved toughness and corrosion resistance due to Carbon and Chromium content. |
| Stainless steel 430 | Stainless steel 430 is magnetic and corrosion resistant. |
| Stainless steel 301 | Stainless steel 301 is corrosion resistant similar to Stainless steel 304. |
| Stainless steel 15-5 | Stainless steel 15-5 has a higher toughness than 17-4, better corrosion resistance and transverse properties compared to other similar martensitic grades. |
Stainless Steel Finishing and Post-Processing
The finish of stainless steel can vary significantly depending on the surface roughness.
However, it is typically described as shinier compared to unfinished aluminum alloys,
and it tends to have a slightly darker and more silver color.
Stainless steel offers flexibility in achieving various surface finishes, including options such as
media blasting, sanding, hand-polishing, and powder coating.
These processes can be employed to achieve a wide range of surface finish textures and
appearances.
| Name | Machining Marks |
| Brushed + electropolishing | Removed on Primary surfaces |
| Electroless nickel plating | Reduced but visible |
| As machined | Visible, light surface scratches |
| Smooth machining | Visible, light surface scratches |
| Fine machining | Slightly visible |
| Polishing | Removed on primary surfaces |
| Bead blasting | Removed for non-cosmetic, removed on primary surfaces for cosmetic |
| Brushing | Reduced for non-cosmetic, removed on primary surfaces for cosmetic |
| Powder coating | Removed |
| Black oxide | Visible |
CNC Machining Applications
The applications of CNC machining are expansive, offering solutions across diverse industries.
In the realm of woodworking, CNC machines revolutionize the production of wooden furniture,
providing efficiency in both time and cost.
Intricate designs that once required master craftsmanship can now be achieved with ease.
For lettering and engraving systems, CNC technology becomes a tool for marking patterns or text
onto surfaces, catering to artistic and serialized needs.
The electrical industry benefits from CNC machining for tasks such as creating precise component
mounting holes in printed circuit boards and manufacturing heat sinks for electronics.
CNC machines also play a crucial role in the pharmaceutical industry, producing precise equipment
like metering pumps, ingredient-dispensing nozzles, and packaging components. In the fast-paced
consumer goods industry, CNC machining contributes to the creation of custom material-handling
machinery for the food and beverage sector, as well as molds for injection-molded plastic used in
food packaging.
Company Profile
FAQ's
1. What are the minimum and maximum dimensions you can machine?
Our CNC machining services cover a range of processes, including milling (3-axis, 3+2-axis,
and 5-axis) and turning. In 3/3+2-axis CNC milling, we can machine parts with dimensions up to
2000 x 1500 x 200 mm (78.7 x 59.0 x 7.8 in.).
For 5-axis milling, the maximum part size is 650 x 650 x 300 mm (25.5 x 25.5 x 11.8 in.).
CNC turning allows for a maximum diameter of 431 mm (17 in.) and a length of 990 mm (39 in.).
When considering smaller parts, we recommend a minimum size of around 10 x 10 x 10 mm
(0.39 x 0.39 x 0.39 in.), with feature dimensions not going below 0.5 mm.
It's important to note that our platform has a maximum part size limitation of 1000 mm (39 in.).
For larger requirements, please reach out to our sales team for personalized assistance.
2. How much does CNC machining cost?
The cost of CNC machining hinges on factors such as complexity, quantity, and lead time.
For an accurate cost estimate, we recommend submitting a 3D CAD model to receive an interactive
quote along with design for manufacturability (DFM) feedback.
Thanks to our proprietary software and automated fixturing processes, upfront non-recurring
engineering (NRE) costs are eliminated. This makes CNC machining economically viable for
quantities ranging from 1 to 200 parts. While prices may align or slightly exceed those of 3D printing,
CNC machining offers superior material properties and surface finishes.
3. How does compare to other suppliers on price?
Making direct comparisons may be complex, but as a rule of thumb, We's prices are usually 25-45%
more economical for plastic injection mold tools and CNC machined/turned parts in comparison to
suppliers in North America and Europe.
