Small screws are what we often call precision miniature screws. Generally, their specifications and sizes are relatively small. Regardless of their small size, in fact, the smaller the screw, the more difficult it is to make. It is not only produced by machine, but also through subsequent processes such as tooth rubbing and electroplating. So I believe many people also want to know how Micro screw are produced? Follow the footsteps of the editor to show everyone:

When producing small screws, a very important part is the heading machine and the thread rolling machine. We must first select the screw wire of the small screw, the production operator must adjust the heading machine, and install the corresponding small screw mold. Then the screw thread piers are punched out in the shape of the screw without screwing the teeth, and then the screwing master will perform the threading treatment. To rub the small screws, you must first have a rubbing machine and a tooth plate, install the tooth plate on the rubbing machine, and then you can rub the small screws. Of course, the above is the process of cold heading. Small screws can also be produced by automatic lathes. A series of feeds are completed in the vibrating material selection tray, basically without manual intervention, but the cost of the lathe is higher than that of cold heading.
