[0002] A CNC sawing machine is a machine tool that uses circular saw blades, saw bands or saw blades as cutting tools to saw metal round materials, square materials, pipes and profiles. The processing accuracy of this machine tool is generally not high, but it has the characteristics of high efficiency, precision and stability. It is widely used in machinery, automobile, aviation and other industries. CNC sawing machines are mainly divided into three types according to the saw blade feed direction: horizontal (horizontal feed), vertical (vertical feed) and swing type (swinging feed around a fulcrum). In addition, there are different types such as band sawing machines and bow sawing machines.

[0003] When a CNC sawing machine is in use, a large amount of metal debris will be generated during the cutting process. These debris are easy to accumulate or adhere to the processing area of ​​the sawing machine. The accumulation of metal debris may cause the saw blade or saw blade to vibrate or deviate during the cutting process, thereby affecting the sawing accuracy and surface quality, and increasing the difficulty of maintaining the sawing machine. Regularly cleaning the metal debris takes a lot of time and manpower. In addition, it may pose a safety hazard to the operator and there is a risk of being cut by sharp metal debris. In addition, if the metal debris splashes into the electrical system, it may even cause a fire. For this reason, a chip cleaning device for a CNC sawing machine is proposed. Utility Model Content
