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.
| Common Materials | |
| Name | Description |
| Aluminum | High machinability and ductility, good strength-to-weight ratio. |
| Stainless steel | High tensile strength, corrosion and temperature resistant. |
| Mild steel | High machinability and weldability, high stiffness. |
| Brass | Low friction, excellent electrical conductivity, golden appearance. |
| Copper | Excellent thermal and electrical conductivity. |
| Titanium | Excellent strength to weight ratio, used in aerospace, automotive and medical industries. |
| ABS | Common thermoplastic, impact resistant, easy to machine. |
| Nylon | Excellent mechanical properties, thermal, chemical and abrasion resistant. |
| POM | High stiffness, high accuracy, low friction, easy to machine. |
Post-processing and surface finishes for CNC machining
CNC-machined parts as they emerge from the machine often exhibit visible tool marks, a feature
that may not align with your specific part requirements.
Fortunately, there exists a multitude of post-processing techniques aimed at enhancing the surface
appearance and elevating attributes such as wear resistance, corrosion resistance, and chemical
resistance.
Methods like anodizing, bead blasting, and powder coating present viable options for refining the
final presentation of your custom parts, allowing you to achieve the desired surface quality and
performance characteristics.
| Surface Finishes | ||
| Name | Applicable to | Machining marks |
| As machined | Metals, Plastics | Visible, light surface scratches |
| Smooth machining | ||
| Fine machining | Metals | Slightly visible |
| Polishing | Metals | Removed on primary surfaces |
| Bead blasting | Metals | Removed for non-cosmetic, removed on primary surfaces for cosmetic |
| Brushing | Metals | |
| Anodizing Type II | Aluminum | |
| Anodizing Type III | Aluminum | Visible under anodizing |
| Black oxide | Copper, Stainless steel, Alloy steel, Tool steel, Mild steel | Visible |
| Powder coating | Metals | Removed |
| Brushed + electropolishing | Stainless steel | Removed on Primary surfaces |

FAQ's
1. How much does CNC machining cost?
The cost is determined by factors like complexity, quantity, and lead time. To get an accurate
estimate, you can upload a 3D CAD model and receive an interactive quote with design for
manufacturability (DFM) feedback.
We do not charge any upfront non-recurring engineering (NRE) costs thanks to our proprietary
software and automated fixturing processes.
This means that even small quantities, ranging from 1 to 200 parts, are cost-effective.
While prices may be similar to or slightly higher than 3D printing, CNC machining offers superior
material properties and surface finishes.
2. What are the minimum and maximum dimensions you can machine?
We offer a wide range of CNC machining services, including CNC milling (3-axis, 3+2-axis, and 5-axis)
and turning.
When it comes to milled parts, our capabilities extend to dimensions of up to 2000 x 1500 x 200 mm
(78.7 x 59.0 x 7.8 in.) for 3/3+2 axis CNC milling, while for 5-axis milling, the maximum part size
accommodated is 650 x 650 x 300 mm (25.5 x 25.5 x 11.8 in.).
For CNC turning, we can handle parts with a maximum diameter of 431mm (17 in.) and a length of
990 mm (39 in.).
On the smaller end, we recommend minimum part dimensions of around 0.39 x 0.39 x 0.39 inches
(10 x 10 x 10mm), with a minimum feature dimension of 0.5 mm.
Please note that our platform has a size limitation of up to 1000 mm (39 in.) for parts. If you require
larger dimensions, you can submit a request through our sales team for further assistance.
3. How quickly can I get 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.
