In the process of using the cutter, some problems will inevitably occur, such as inaccurate cutting accuracy and abnormal movement. Today we will talk about the reasons that cause the impact noise when the paper cutter is cutting.
        After using the paper cutter for a long time, sometimes the impact sound will increase obviously during cutting. Why is this? There are several common reasons:
        First, the needle bearing inside the left threaded rod is damaged;
        The second is that the two sliders of the knife holder are seriously worn, and the cooperation gap with the knife holder chute is increased;

        The third is the wear between the worm gear and the worm (mainly the wear of the worm gear).
