The difference between CNC parts processing and CNC processing plastic parts

    The metal parts are relatively simple. After all, if you do this kind of work, you will be skilled. Generally, those who have been doing it for a few years will never be hand-fed. The difference lies in the grasp of different metals. This is relatively easy to say.

    Plastics are easy to crack due to internal stress. In addition to controlling the knife speed during CNC parts processing, attention should also be paid to cooling. It is not just a blind cooling.

    Plastics have a certain temperature suitable for processing.

    It is low, easy to crack, deform, and burrs will damage the corners. The more obvious is acrylic. The corners are easy to crack.

    High, the contact position will melt, wrap the knife, and form adhesion. The processed surface will form a white "film"-like thing. Can't wash off, can't wipe off.

    The machining surface of cnc parts is easy to scratch. After all, the hardness is low. Generally, when buying raw materials for plates and bars, you need to pay attention to choosing the surface protective film that is intact and scratch-free. The selection of noodles is also important when processing. Confirm which surface is to be processed. Hold it where you can't clamp it.

    The processing table and clamping mechanism must also be cleaned. Otherwise, the plastic will be dried as soon as the stainless steel is processed. The result is one by one. There is also something like a bench vise, it is best to be able to pad something. Many bench vices have a tooth-like structure in their clamping position, and nothing more than metal parts. PE, PVC, ABS, pom can not stop them.
