What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

Talking about the Application of Beryllium Copper in Plastic Mould

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 conductivity required for tungsten die manufacturing, simple and convenient machining, long mold life, and save development and production cycle.

 

  1. Good thermal conductivity: The thermal conductivity of beryllium copper material is beneficial to control the temperature of the plastic machining mold, and it is also easier to control the molding cycle, while ensuring the uniformity of the mold wall temperature; if compared with the steel mold, the molding of beryllium copper The cycle is much smaller, and the average temperature of the mold can be reduced by about 20%. When the difference between the average ejection temperature and the average wall temperature of the mold is small (for example, when the mold parts are not easy to be cooled), use the beryllium copper mold material to cool The time can be reduced by 40%. The mold wall temperature is only reduced by 15%; the characteristics of the above beryllium copper mold materials will bring several benefits to the mold manufacturers using this material to shorten the molding cycle and increase the productivity; the uniformity of the mold wall temperature improves the quality of the drawn products; The mold structure is simplified because the cooling pipes are reduced; the temperature of the material can be increased, thereby reducing the wall thickness of the product and reducing the cost of the product.

 

  1. Long service life of the mold: Budgeting the cost of the mold and the continuity of production, the expected service life of the mold is very important for the manufacturer. When the strength and hardness of the beryllium copper meet the requirements, the temperature of the beryllium copper Stress insensitivity can greatly improve the service life of the mold. Before determining the use of beryllium copper mold materials, the yield strength, elastic modulus, thermal conductivity and temperature expansion coefficient of beryllium copper should also be considered. The resistance of beryllium copper to thermal stress is much stronger than that of die steel. From this point of view, the service life of beryllium copper is remarkable!

 

  1. High thermal penetration rate: In addition to the thermal conductivity of the pull, the thermal penetration rate of the powder metallurgy mold material is also very important to the plastic products. On the mold using beryllium bronze, the traces of overheating can be eliminated. If the thermal penetration rate is low, The contact temperature of the distal region of the mold wall will be higher, which will increase the temperature difference of the mold, and in extreme cases will cause the temperature of the region to change from the sink mark at one end of the plastic product to the trace of overheated product at the other end .

 

  1. Excellent surface quality: beryllium copper is very suitable for surface finishing and can be directly electroplated, and the adhesion performance is very good, and the polishing treatment of beryllium copper is also very easy.
