The difference between cnc part processing and CNC machining of plastic parts

What is the difference between cnc part processing and CNC machining plastic parts? Don't worry, listen to me slowly.

Metal parts are relatively simple. After all, if you process it, you will be skilled in this kind of work. Generally speaking, it will not be a hand-made tide for a few years. The difference lies in the different metals. This is relatively good to say something.

Plastics are easy to crack because of the internal stress. This is to control the speed of the knife when machining the cnc parts. It is also necessary to pay attention to the cooling. It is not necessary to cool down.

Plastics have a certain temperature suitable for processing.

It is low, easy to crack, deformed, and burrs will hurt the angular position. More obvious is acrylic. The corners are prone to collapse.

When it is high, the contact position will melt and wrap around the knife to form a bond. The processing surface will form a white "film" shape. Can't wash it, can't wipe it off.

The surface of the cnc part is easily scratched. After all, the hardness is low. Generally, when buying raw materials for bars and bars, you need to pay attention to the selection of the surface protective film without scratches. Candidate faces are also important during processing. On which side the processing is to be confirmed. Where to hold it, where you can't hold it.

The processing table and the clamping mechanism must also be cleaned. Otherwise, just dry the plastic after processing the stainless steel. The result is a one-by-one. There is also something like a vise that can best be something. Many vise clamping positions are tooth-shaped structures, and metal parts are gone. PE, PVC, ABS, pom can't stop it.
