What is the difference between CNC metal machining and CNC plastic machining?

The metal pieces are relatively simple. After all, if we do many CNC metal processing, more this work more , more skilled. Generally do a few years will never make little mistakes. The difference lies in the grasp of different metals. This is relatively good to say.

Plastic because of the relationship between the internal stress, easy to crack, in the control of the knife speed, the cooling should also pay attention to, not blindly cool can make it.

Plastic has a certain temperature suitable for processing.

Low temperature, easy to crack, deformation, burr will hurt the angular position. More obvious is the acrylic. Corner easy to collapse.

High temperature, the contact position will melt, knife, forming adhesion. The processing surface will form a layer of white "film" shaped things. Can not be washed or be rub.

Easy to scratch the surface. After all, low hardness. General plate, bar to buy raw materials need to pay attention to the selection of surface protection film complete without scratches. Processing time is also very important. In which side to confirm the processing of good. Caught in what place, where can not be caught also grasp.

Machining tables and gripping mechanisms must also be clean. Or just finished processing stainless steel on dry plastic. The result is a plan together. There are things like tiger tongs that can pad the best thing. A lot of tiger clamp clamping position is the dentate structure, metal pieces is okay. But to PE, PVC, ABS, pom,  no one can stop to be scratched.

Prepare work before processing. First drop the material well, and according to different materials,  use hot water to immerse, the release the internal stress of materials.

Ah, that’s all. I estimate that it won’t has many people to read it. Someone to see and write it again.
