[0002] A lathe is a machine tool mainly used for turning a rotating workpiece with a turning tool. It is one of the most common and important metal cutting machine tools. Lathes can machine various rotating surfaces and helical surfaces with different sizes and shapes, such as outer circles, inner holes, end faces, grooves, chamfers, threads, etc.

[0003] Since a lathe relies on a turning tool to cut the workpiece to achieve the processing purpose, a large amount of chips will be generated during continuous processing. The chips will accumulate on the bed and need to be regularly cleaned by the staff, which is rather troublesome. Summary of the Invention

After the chips are conveyed to the chip discharging port, they are discharged downward through the chip discharging port. The discharged chips will fall into a chip collection bucket below the chip discharging port and the chips are collected uniformly; moreover, when the first rotating shaft rotates, it will drive the cylindrical brush shaft to rotate. When the cylindrical brush shaft rotates, it drives the cylindrical brush on it to rotate.
