Talking about the function of screw thread on the lathe
Threads are widely used in various machines. For example, four screws are used on the square tool rest of the lathe to realize their movement relationship. The spindle drives the workpiece to rotate together. The movement of the spindle is transmitted to the feed box through the change gear box, and then to the lead screw after the feed box changes speed. The lead screw and the opening and closing nut on the slide box cooperate to drive the tool rest and turning tool to move in a straight line, In this way, the rotation of the workpiece and the movement of the tool are driven by the spindle, which ensures the strict movement relationship between the workpiece and the tool. In actual thread turning, due to various reasons, the movement between the spindle and the tool has problems in a certain link, which causes faults in thread turning and affects normal production. At this time, it should be solved in time.

Now for the clamping of turning tool, the screw thread is used to transmit power between the lathe lead screw and the opening and closing nut. There are many methods of machining threads, and the method of threading is usually used in general machining (one of the basic skills of lathe workers). When machining threads on a horizontal lathe, it is necessary to ensure the motion relationship between the workpiece and the tool, that is, each revolution of the spindle (one revolution of the workpiece), the tool moves a pitch (or lead) evenly.
