These waste chips will get stuck in the gaps of machine tools, which are not easy to clean up, and will affect the normal operation of machine tools, reduce work efficiency, and shorten the service life of machine tools and equipment. CNC machine tools, machining centers, grinders, and automatic lines will generate a lot of metal flying chips during grinding, such as metal sand, abrasive particles, and aluminum chips in the automotive industry. Some metal chips are relatively large and long, while some are small. These metal chips can easily fall into the gaps of processing equipment or production lines, affecting the normal operation of processing equipment or production lines. In serious cases, they will get stuck and must be stopped for chip removal, which is very inconvenient to use, affecting machine tool processing, low efficiency, and shortening the service life of mechanical equipment.
