Utilizing computer numerical control, or CNC, machining is a widely adopted manufacturing
technique that relies on automated, high-speed cutting tools to fashion designs from metal or
plastic stock.
Common CNC machines include 3-axis, 4-axis, and 5-axis milling machines, lathes, and routers.
The manner in which CNC parts are cut can vary, with scenarios where the workpiece remains
fixed while the tool moves, the tool remains stationary while the workpiece is rotated and moved,
or both the cutting tool and workpiece move simultaneously.
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.

CNC Machining Applications
CNC turning machines showcase their versatility by crafting an array of parts with varying
intricacies. Among the parts manufactured are shafts and axles, ideal for industries like automotive
and aerospace.
Additionally, CNC turning is adept at producing precision bushings and bearings crucial for reducing
friction in mechanical assemblies. The scope extends to connectors, fittings, fasteners such as
screws and nuts, as well as valves and valve components.
Furthermore, CNC turning plays a pivotal role in creating tooling components like inserts, toolholders,
and bodies, contributing to enhanced efficiency and accuracy in machining operations.
In the automotive sector, CNC turning is harnessed for crafting engine components, pulleys, brackets,
and specialized parts.
