What is CNC Plastic Machining
CNC plastic machining is a precise and efficient subtractive manufacturing process where a cutting tool removes material from a solid plastic block to shape complex components. Utilizing advanced 3-, 4-, and 5-axis CNC machines, this method enables the production of plastic parts with intricate geometries, tight tolerances, and high dimensional accuracy. It is ideal for creating multi-sided prototypes, functional components, and end-use parts across a wide range of industries.
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.
Use CNC Plastic Machine for Production
Choosing the right manufacturing process can be challenging, especially when working with tight deadlines and budgets. If your project aligns with the following conditions, plastic CNC machine may be the ideal solution:
When to Consider CNC Plastic Machining:
-
You have a limited project budget
-
You need functional plastic prototypes
-
A fast turnaround time is essential
-
Your production volume is low or customized

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.
Plastic CNC milling machines used by Runsom Precision mounted with dual spindles can deal with complex projects in a fast cycle time and with fewer setups, showing better performance than traditional single-head production methods.

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.
