How does precision CNC machining achieve high precision engineering plastic parts?

2025-06-26


Processing Methods



1.    Milling


It is suitable for processing parts with various complex shapes, offering high processing precision and good surface finish.


2.    Drilling


Drilling is characterized by fast speed and high efficiency. However, there may be issues such as plastic melting or burr generation. Attention should be paid to the use of cutting fluid.


3.    Turning


It is applicable to parts that require rotational symmetry, providing high processing precision. But the equipment cost is relatively high.


4.    Cutting


It is suitable for processing large-sized plates, with fast cutting speed but relatively low precision.


5.    Engraving


It utilizes small tools for fine engraving to create patterns, texts, or textures.



Plastic Materials:


· ABS: It has high impact resistance, is easy to dye, and boasts excellent comprehensive properties.


· POM (Polyoxymethylene): It features high rigidity and good wear resistance.


· PA (Nylon): It offers good toughness and wear resistance.


The processable materials cover general-purpose engineering plastics such as ABS, PC, POM, as well as special high-temperature materials like PEEK, PEI, and PTFE.


Field of Applications



The CNC plastic machining process is widely applied in fields such as aerospace, automotive manufacturing, medical devices, and electronic products, and is used to manufacture various plastic parts, models, prototypes, etc.
