What is CNC Plastic Machining
Plastic CNC machining is a viable subtractive manufacturing process in which a moving cutting tool removes material from a solid block of plastic that is placed against it, thus complicated plastic components are created. This process may involve 3, 4, and 5-axis CNC machines to produce multiple sides and end plastic parts with intricate geometries.
Compared to some plastic machining methods like 3D printing or injection molding, CNC machining plastics can be a more ideal option for projects needing tighter tolerances and can be used with a wider array of polymer materials. Moreover, it is more suitable for low-volume production versus injection molding as it’s more cost-effective.
Advantages of Plastic CNC Machining
Since plastic CNC machining needn’t make a mold, it’s a preferable alternative for one needing a prototype to be made in a fast cycle time. So the process of machining the prototype will be faster.
Some processes like injection molding consume many resources and much time in building molds, but plastic CNC machining is free of that. Therefore, the expense involved in part production is much cheaper than other processes.
For parts to be applied to high-precision industries like aerospace or medical, CNC machining plastics may be a significant option for production. That is because it can conform to tight tolerance standards.
The plastic part machined by CNC machining holds its distinguished resistance to corrosion over metal products due to the fact that it can prevent from being rusting after extended use.
When to Use CNC Plastic Machining for Production
It could be such a difficult task for you to choose the exact production process. If your project requirements fit these factors below, you can take the plastic CNC machining into account.
Main factors in choosing plastic CNC machining
- There is a limited budget for your project
- There is only a need for plastic prototypes

CNC Plastic Machining Types We offer
Plastic CNC milling
Tips for CNC milling plastics:
1. Use carbon tooling when machining a thermoplastic that has been hardened with carbon fibers or glass.
2. Take clamps to realize higher spindle speeds.
3. Utilize end mills to relieve stress concentration by forming rounded internal corners and pockets.
Plastic CNC turning
Tips for CNC turning plastics:
1. Ensure there is a negative back rake in cutting edges to minimize rubbing.
2. Using good C-2 grade carbide inserts.
3. Polish top surface to form a flat surface finish and reduce material buildup.
4. Utilize generous relief angles for cutting edges.
Plastic CNC drilling
Tips for CNC drilling plastics:
1. Keep CNC drill bits sharp to reduce the stress on the part. Different lip angles should be accommodated according to different types of plastics.
2. Pay attention to the ejection of the CNC drill. It is important to make sure the drilling depth not to exceed three or four times the drill diameter and to lower the feed rate when the material nearly is exited from the drill.
Plastic Swiss CNC machining
Tips for Swiss CNC machining plastics:
Choose the correct tooling speeds to eliminate temperature restrictions occurred when machining with thermosetting polymers or thermoplastics.
Furthermore, we also have the capabilities of 3D programming, CAD design, and CAM programming.
Our precision CNC machines make it possible to process all kinds of plastic components ranging from micro milling to 6’ x 10’ parts.

CNC Machining Plastics FAQs
In plastic CNC machining, a plastic block is processed to form a final desired shape, size, or surface finish. This process is also known as a subtractive technology since unwanted geometry is removed from a raw block of plastic. There are a wide variety of resins to choose from, so the part can be exactly created in the proper material. This rapid prototyping method is economical and efficient for unit production for functional testing.

ABS may be an all-purpose plastic for CNC machining because of its excellent dimensional stability and machinability. POM can be taken into account when the application requires high stiffness and low friction. Other specific requirements like mechanical or aesthetic properties will greatly determine the final selection of plastics.
There would be much fewer surface finish choices in plastic CNC machining when compared to metals. However, the post-processing in CNC machining of plastics might not be needed anymore, because a near-net final surface would be left when the operation of this process is carried out properly.
Suitable CNC plastic finishes include:
- Bead Blasting
- Painting
- Brushing
There is no need to make a mold in CNC machining plastic, so it could be cost-saving and time-saving for rapid plastic prototyping.
