In order to replace the traditional and make up for metal, thin tube welding fusibility, and welding nuts are not smooth, rivet nuts have gradually entered people's field of vision. In addition, the development of various industries in recent years has continued to rise, driving the development of the nut industry to move forward steadily. As we all know, there are many types of blind rivet nuts, and a knurled rivet nut is one of them. So about the knurled rivet nut, how is its thread processed?
Use tools for making threads to process workpieces by cutting, turning, milling, and grinding. Make the workpiece have a thread of a specific shape. Generally refers to the method of machining threads on a workpiece with a shaped tool or abrasive tool, mainly including turning, milling, tapping, threading grinding, grinding, and whirlwind cutting. When turning, milling and grinding threads, every time the workpiece rotates, the transmission chain of the machine tool ensures that the turning tool, milling cutter, or grinding wheel moves accurately and evenly along the axis of the workpiece by one lead. When tapping or threading, the tool (tap or die) rotates relative to the workpiece, and the first formed thread groove guides the tool (or workpiece) to move axially.
The above are some methods of thread processing, of course, there are several other methods. But the probability of these types of use will be higher. The custom rivet nut is mostly processed in these ways.
