The term CNC, short for computer numerical control, characterizes the technology at the core of
CNC machining, a process where machining operations are guided and managed by a computer.
This computerized approach enables the efficient production of parts with heightened speed,
accuracy, precision, and the capability to achieve intricate geometries beyond the reach of manual
machining.
Moreover, CNC machining diminishes the reliance on manual labor for machining tasks that would
traditionally be performed by humans. While individuals are not directly involved in the physical
machining of each part, their involvement is pivotal in programming and operating CNC machines
to ensure the smooth execution of every operation.

| 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. |
CNC Machining Applications
CNC milling stands as a cornerstone in manufacturing, offering efficiency, precision, and the
elimination of manual labor. Machine shops play a critical role in providing essential services for

FAQ's
1. What is your typical lead time? Can my parts be produced on a rush basis?
For screw machine products, our usual lead time—covering quoting, manufacturing, and shipping
—is approximately one week, with an impressive on-time delivery rate surpassing 99%.
Depending on various factors such as tooling, gauges, and material availability, there's potential
to expedite the production of your parts. Just let us know your requirements!
2. Do you offer reverse engineering services or suggest cost saving measures?
In addition to providing reverse engineering services, we excel in extracting design and engineering
details from diverse manufactured components. Our support extends to assisting in the design
process, recommending optimal raw materials, and advising on efficient machining and finishing
strategies.
Our approach considers the end-use of the part, enabling us to pinpoint subtle design modifications,
material alterations, or tolerance adjustments that can lead to cost savings without sacrificing quality
or performance.
3. Do you offer other services, like finishing, assembly, packaging, and logistical support?
From finishing processes to logistical support, we offer a complete suite of services to efficiently and
cost-effectively bring your parts from inception to completion. Our capabilities encompass anodizing,
plating, grinding, finishing, assembly, warehousing, packaging, and just-in-time delivery.
Our aim is to provide a one-stop, hassle-free production process, allowing you to save time and
money while concentrating on your core business.
4. What type of design files does We accept for quoting?
For precise and prompt quoting, we exclusively accept 3D CAD files in STL, STEP, or IGES formats.
For 2D drawings with reference dimensions, please submit them in PDF format.
It's essential to include comprehensive manufacturing information as part of your technical
documentation. Informal communication through Whatsapp, email, etc., will not be deemed
acceptable for manufacturing purposes.
