Cost Considerations for CNC Machining Materials
The cost of materials in CNC machining can fluctuate significantly due to the extensive array of
available options. Each material carries its unique price tag, and the inherent physical properties
of each material play a substantial role in determining machining costs.
For those seeking to manufacture metal components, Aluminum 6061 stands out as the most
cost-effective choice.
On the other hand, ABS ranks as the most budget-friendly option among materials.
As for the influence of machining complexity on costs, stainless steel serves as an illustrative example.
Its inherent hardness, surpassing that of aluminum, renders it more challenging to machine,
consequently elevating the overall machining expenses.
Here is a comprehensive overview of the most popular materials.
| The Most Popular Materials | |
| Name | Characteristics |
| Aluminum 6061 | Good strength-to-weight ratio, excellent machinability, low hardness |
| Stainless Steel 304 | Excellent mechanical properties, resistant to corrosion & acid, relatively difficult to machine |
| Brass C360 | High ductility, excellent machinability, good corrosion resistance |
| ABS | Excellent impact resistance, good mechanical properties, susceptible to solvents |
| Nylon (PA6 & PA66) | Excellent mechanical properties, high toughness, poor moisture resistance |
| POM (Delrin) | High stiffness, excellent thermal & electrical properties, relatively brittle |

FAQ's
1. What's the general surface texture of CNC milled and turned parts?
In the realm of CNC machining, as-machined milled parts typically exhibit a surface roughness of
approximately 3.2μm (or 1.6μm in the case of relatively new machines).
On the other hand, when it comes to turned parts, we can achieve a smoother surface with a roughness
of 0.8μm.
This means that machining speed adjustments are not necessary to attain this level of surface finish.
2. How do you speed up CNC manufacturing?
The pace of manufacturing in CNC machining is influenced by various factors, encompassing part design
and the desired surface finish.
One illustrative approach to expedite the machining process is by incorporating fillets instead of sharp
corners in your design.
This design adjustment allows for the use of standard tools throughout production, eliminating the need
for tool changes during machining and thereby enhancing manufacturing speed.
3. How soon can I receive my parts?
We can produce quality parts in as little as two weeks if you provide us with complete 2D and 3D CAD
models.
However, more complex parts with special features may have longer lead times. Request a quote to
receive more precise lead times based on your specific project.
Regarding shipping, our primary method is air freight, which typically takes a few days for delivery from
China to Europe or North America.
