Product Details
What raw materials can I use with CNC machining?
Virtually any sturdy and solid material can be subjected to CNC machining, including mild and
stainless steels, aluminum, brass, copper, magnesium, titanium, and a wide array of engineering
plastics.
| 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.

Post-Machining Essentials: Deburring and Inspection
Following the machining process, it's essential to perform deburring on milled parts.
Deburring entails the manual removal of minor imperfections from a finished component.
These imperfections typically appear on sharp edges and result from material deformation
during machining. For instance, when a drill exits the far side of a through hole,
it may leave behind blemishes that require attention.
Subsequently, it's crucial to inspect the part's critical dimensions, especially if specific
tolerances were specified in the technical drawing. Once this inspection is complete,
your part is ready for immediate use or for any necessary post-processing.
The realm of post-processing for CNC-machined parts, whether they are milled or turned,
offers numerous avenues to explore. Therefore, we recommend enhancing your knowledge
and expertise in this area to optimize your CNC machining outcomes.
