Pitting corrosion and pits are common surface quality problems in carbon steel seamless pipe manufacturing. When delivering pits and potholes, if this happens, many seamless steel pipe mills will say that the quality problems of the original steel mills have caused this problem. The choice of round steel may have an impact on carbon steel seamless pipemanufacturing, but it is not the final deciding factor. The real reason lies in this process-perforation.   Many seamless steel pipe plants have unreasonable selection of equipment for piercing furnaces. The short perforation furnace prevents the round steel from being evenly heated, resulting in large internal and external temperature deviations, affecting structural changes, and causing the setting of pits and pit plugs. Generally, inferior plugs are used in seamless steel pipe factories. The water sprayed from the plug directly touches the inner and outer surfaces of the high-temperature steel pipe, and the steel pipe encounters ... Continue reading →

Nowadays, more and more beryllium copper mold materials have been used in the manufacture of plastic molds, and there is a rising trend. What is the reason for this phenomenon? Let me learn about the use of beryllium copper in plastic molds with the editor, and why.   1. Sufficient hardness and strength: After many tests, engineers can find out and master the hardening conditions and working conditions of beryllium copper machining alloy precipitation and the mass characteristics of beryllium copper (this is the point that the beryllium copper alloy is based on A prelude to the application of formal products in the market); beryllium copper materials need to go through multiple cycles of tests before they are used in plastic molds to finally determine the physical properties and chemical components that meet the manufacturing and processing; the proof of theory and practice-beryllium When the hardness of copper is hrc36-42, it can reach the hardness, strength, high thermal ...

The existence of forging defects may affect the processing quality or processing quality of the subsequent processes, and some seriously affect the performance and use of the forgings, and even greatly reduce the service life of the finished parts and endanger safety. Therefore, in order to ensure or improve the quality of cold forgings, in addition to strengthening quality control in the process and taking corresponding measures to prevent the occurrence of forging defects, necessary quality inspections should also be carried out to prevent subsequent processes (such as heat treatment, surface treatment, cold processing, etc.). ) And forgings with defects that have adverse effects on performance will flow into the subsequent process. After quality inspection, remedial measures can be taken on the forgings made according to the nature of the defect and the degree of influence to use, so that it meets the technical standards or requirements for use. Therefore, in a sense, the quality ... Continue reading →

  Compared with conventional CNC titanium machining processes, the outstanding advantages of turning-milling combined machining are mainly manifested in the following aspects:   (1) CNC turning and milling compound processing manufacturers introduced to shorten the product manufacturing process chain and improve production efficiency. A variety of special tools can be installed, new tool arrangement, reduce tool change time, improve processing efficiency, turning-milling composite processing can complete all or most of the machining procedures in one clamping, thus greatly shortening the product manufacturing process chain. In this way, on the one hand, the production assistance time caused by the change of the installation card is reduced, and the manufacturing cycle and waiting time of the tooling fixture are also reduced, which can significantly improve the production efficiency.   (2) Reduce the number of clamping and improve cnc brass machining accuracy. The ... Continue reading →

  1. Parts with high precision requirements   The precision requirements of precision CNC machining parts mainly refer to the precision requirements of size, shape, position and surface, and the surface precision mainly refers to the surface roughness. Because the CNC lathe has good rigidity, high precision in manufacturing and tool setting, and can easily and accurately perform manual compensation and automatic compensation, it can process shaft parts with high dimensional accuracy. In some cases, it can achieve the effect of turning instead of grinding. In addition, because the motion of the CNC lathe is realized by high-precision interpolation and servo drive, it can process parts with high shape accuracy requirements such as straightness, roundness, and cylindricity.   Because the CNC lathe can complete a lot of processing content in one clamping, it can effectively improve the position accuracy of the parts, and the processing quality is stable. The CNC lathe has ... Continue reading →
