Machine Service
CNC machining, or Computer Numerical Control machining, constitutes a subtractive manufacturing
method employed for the creation of parts through the removal of material from a workpiece or
workpiece stock.
The machine's movement is controlled by preprogrammed software and codes, guiding the precision
of material removal. This versatile process encompasses various machinery, including turning mills,
lathes, grinders, and plasma-cutting machines.
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
CNC milling, renowned for its efficiency, accuracy, and the elimination of manual labor, finds
widespread application across diverse industries. Machine shops, offering critical services for
prototypes and full production runs, play a pivotal role in the manufacturing process.
Notably, the electronics industry heavily relies on CNC machines to produce electronic enclosures
and circuit supports. In the commercial sector, CNC cutting heads contribute to the creation of
affordable parts, reducing production costs and saving time.
The oil and gas industry utilizes CNC machines for the production of various components like drill
bits, cylinders, pins, rods, and valves. Similarly, CNC milling tools are indispensable in the medical
industry for creating implants, surgical equipment, and medical devices.
Finally, the aerospace industry benefits significantly from CNC machined parts, utilizing this
technology for the production of complex, customized components essential for aerospace equipment.
Company Profile
FAQ's
1. Can make design drawings for me?
While we don't provide a standalone product design service, we do conduct Design for
Manufacturing reviews for all approved orders. This entails working closely with our clients to
optimize their 2D and 3D drawings, addressing design conflicts, and minimizing production costs.
Check out our guidelines on preparing CAD drawings for manufacturing.
2. What type of design files does We accept for quoting?
To ensure accuracy and efficiency in quoting, we exclusively welcome 3D CAD files in STL, STEP,
or IGES format. For 2D drawings with reference dimensions, kindly provide them in PDF format.
Complete manufacturing information must be included in the technical documentation for a
thorough assessment. Please note that informal communication via Whatsapp, email, etc.,
will not be acknowledged for manufacturing purposes.
3. How do I know my design will be kept confidential?
Your design's confidentiality is paramount to us. We are willing to sign and strictly adhere to any
non-disclosure or confidentiality agreement. Moreover, our factory has a stringent policy against
taking photographs of a customer's product without explicit permission.
Our reputation is founded on years of experience working with a multitude of unique designs,
and we have never allowed any proprietary information to be disclosed to third parties.
4. 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.
