Cutting processing is generally lathe processing, which is to find an iron rod that is a round rod of the material you need. But for the majority of ordinary people, this is not necessarily known, unless you have visited the screw factory to learn. When it comes to special screws, the first thing most people think of is the particularity of the material. Now I will briefly introduce you to those special screws. Screw factories are generally formed by extrusion processing. can be customized according to user needs. This type of processing method is suitable for small batches and high-precision processing. What are the characteristics of special screws? Many technical engineers know that special screws are very practical, and engineers love to use them the most, but people who have not been in contact with this industry do not understand. Compared with ordinary screws, the materials of special screws are wider, such as non-ferrous metals/ferrous metals. Extrusion processing is processed by professional screw equipment, Sleeve anchor which is called thread rolling machine in the screw factory industry. The diameter of the round bar is the maximum outer diameter of the special screw. However, the processing cost is high and the efficiency is low. Secondly, the size and shape of special screws are not limited by various national standards. For example, if titanium is used as a raw material for production, the overall quality of the product is light. It is also one of the most important characteristics of special screws that are used in harsh environments such as high temperature resistance and extreme bottom temperature to meet the design requirements.Specialized screw processing principle professionals are disregarded, so simple knowledge is showing off here
