Computer numerical control machine tool machining accuracy and processing efficiency, but its processing will produce a lot of iron scraps, for some machine tools can not automatically clean up iron, still using the traditional method, that is, the accumulation of scrap iron until the machine by the machine operation The machine operator to clean up the surface of the debris dirt, and some use high-pressure air gun blowing, making the clutter dirt scattered. And time-consuming labor, affecting the workshop environment, it may also cause pollution to the machine. My company's centralized chip removal system, a good solution to this problem.
