With the development of the machining industry, more and more parts are produced by cold-moulding in production, and more and more types of cold-deformed molds are used. Cold volume die forging (cold enthalpy, cold extrusion, embossing, etc.); sheet metal stamping (such as drawing, blanking, trimming, punching, etc.); material rolling (cold rolling, rolling forming, etc.). [...]
As a mechanical design engineer, when the designed parts need to be heat treated, it is necessary to eliminate the casting stress of the material and improve the cutting performance, rigidity and wear resistance of the parts. Below we will introduce the method of heat treatment of the parts. 1. [...]
The machining error reflects the level of machining accuracy. For mechanical processing plants, to ensure the quality of the product, the first thing to do is to control the error in the processing. So, what are the common machining errors in actual production? Let's take a look at it in detail. 1. Manufacturing [...]
The mold manufacturing process is a complex process. From design, processing, assembly, commissioning to final real use, there are many factors affecting the quality of the mold throughout the life cycle, which requires the attention of the operator during the processing. What are the reasons that affect the quality of the mold? [...]
In the single-piece CNC machining, the blank is generally processed. Therefore, there will be interference of excess blank amount when the reverse machining is performed, and other tools are needed to meet the requirements. In the actual processing, although the ordinary reverse-side method can meet the requirements, there are problems such as cumbersome operation [...]
Turning is one of the most widely used in the machinery manufacturing industry. The number of lathes and worker are large, the processing range is wide, and the tools and fixtures used are numerous. Therefore, the safety technical problems of turning processing are particularly important. This article will give you a detailed introduction to the safety [...]
The occurrence of wear during machining is a common phenomenon in production. The reason may be due to various factors such as the material of the workpiece, the environment, and the processing method. Mechanical wear can adversely affect the processing quality, processing accuracy and processing efficiency of the product. Therefore, it is very important [...]
In machining, burrs are often generated during the process of cutting metal. The burrs not only have a serious impact on the accuracy and surface quality of the workpiece, but also affect its practical performance. In end milling, the formation of burrs is affected by many factors, which not only has a great relationship [...]
FRP is a thermosetting plastic product with epoxy resin as binder, glass fiber as filler and small amount of compounding agent. Its density is small and its specific strength is high. The main component is silicon oxide, which is formed by high-speed melting of glass after high-temperature melting, and its hardness and strength are [...]
In the process of mechanical production, stainless steel is often used in processing due to its corrosion resistance in the atmosphere or corrosive media. Stainless steel can be classified into chrome stainless steel and chrome nickel stainless steel according to chemical composition. According to its metallographic structure, it can be divided into martensitic stainless [...]
