CNC parts machining and CNC machining plastic parts

Metal parts are relatively easy. After all, if you're machining, you've done a lot of this kind of work, and you're skilled at it. Generally dry a few years of absolutely not hand tide. The difference lies in the grasp of different metals. This is relatively good to say some.

Plastic because of the relationship between the internal stress, easy to crack, this cnc parts processing control knife speed, cooling should also pay attention to, not a flavor of cooling can be.

Plastic has a certain temperature suitable for processing.

Low, easy to crack, deformation, burrs will bruise the angular position. More obvious is acrylic. The corners are easily chipped.

Higher, the contact position will melt, wrap the knife, the formation of adhesion. Processing surface will form a layer of white "film" thing. Can not be washed off, can not be wiped.

The surface of cnc parts processing is easy to scratch. After all, low hardness. General plate, bar buy raw materials need to pay attention to, select the surface of the protective film intact without scratching. It is also important to choose the surface when processing. In which surface processing to confirm. Where to clamp and where not to clamp should also be grasped.

Processing table, the clamping mechanism must also be cleaned. Otherwise, just after processing stainless steel on the dry plastic. The result is a line of scratching. There are table vise such a thing, can pad something best. Many table vise clamping position is tooth structure, metal parts are just. PE, PVC, ABS, pom a can not stop.
