In fact, before going through this step, the screw is already a semi-finished product. We need to go through this step to achieve the thread we want. Here we call the screw thread rolling, the South Threaded Bar means the thread rolling, and the nut means the tapping. In the same way, we fix one of the dental plates, and the other can be moved, squeezed and deformed to form our threads. This is the whole process like this. It seems simple, but you have to pay attention to these and other problems during operation.

The first thing we need to consider is quality. If the following problems arise, we have to reflect on where there are errors in the entire process, and where are we neglected? Here we ask that we have a certain awareness of prevention for the problems of the entire process, and this is also the requirement of our quality awareness.

If the teeth are not full during operation, the relative position is not adjusted properly, or the molding error occurs, it will directly lead to the phenomenon of small outer diameter of our teeth. This is a frequent occurrence and we should pay attention to it. Second, if the effect of the tooth base is not very good, it is necessary to adjust the angle of the fixed tooth plate immediately; there is also the possibility of the problem of the tooth tip, which requires correction of the tooth plate to ensure a good appearance. There can be no crooked rods and problems with Asan. In fact, to do a good job of quality control requires us to pay more attention. We must master the angle of mediation, and we must know the reasons for each part. Only in this way can we make our own products. Otherwise, there will be problems like this and that, the first link will affect the second link, and the final result is that our work is still not done well, and our quality is still not improved. Such steps cannot happen to us. During the production process.
