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

Investment Casting Materials and Manufacturing Process

Mold material The performance of the molding material should not only ensure the convenient production of investment molds with accurate dimensions and high surface finish, good strength and light weight, but also create conditions for the manufacture of mold shells and good castings. Molding materials are generally formulated with waxes, natural resins and plastics (synthetic resins). All mold materials mainly prepared with wax materials are called wax-based mold materials, and their melting point is low, 60~70 ° C; all mold materials mainly prepared with natural resins are called resin-based mold materials, with a slightly higher melting point, about 70 °C. ~120℃. invest-casting.com   Precision Investment Castings China prototype company service include :  High Quality Investment Casting Parts Custom , Lost Wax Investment Casting Sand Casting , Lost Foam Casting , Gravity Casting , Die Casting , Graphite Casting , Casting Moldsmanufacturers .

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

Simulated radiator heat transfer performance comparison table Simulated radiator resistance performance comparison

 

From the simulation data of the double-drain pipe type radiator, the wave distance can be known from the simulation data. The water flow rate of the first drain pipe is basically the same, but the heat dissipation capacity of the second drain pipe is obviously smaller than that of the first row, which is only the first row. The simulation results found that after the cooling air exchanges heat with the second drain pipe, the temperature rises, and the temperature of the air inlet that exchanges heat with the second drain pipe increases, so that the average temperature difference between water and air in the second drain pipe decreases. According to the knowledge of heat transfer, the heat dissipation coefficient of the radiator is related to the average temperature difference between water and air, which is why the heat dissipation of the first drain pipe is significantly smaller than that of the first row. Comparison of results and conclusions The analysis table and table are the comparison of heat transfer performance and resistance performance of single drain pipe and double drain pipe radiator.

Table simulated radiator heat transfer performance comparison table simulated radiator resistance performance comparison can be seen from the table, although the heat dissipation area of ​​the double drain pipe radiator is twice that of the single drain pipe radiator, but under the same working conditions, the double drain Compared with the single drain pipe type, the heat dissipation of the pipe type is only increased, but the wind resistance is nearly doubled. At the same time, the material used to manufacture the double drain pipe type radiator is also the same as the single drain pipe type, so the quality and manufacturing cost of the radiator will increase accordingly. Considering the heat transfer performance, resistance performance, economy and reliability of the radiator, it is not the most effective method to increase the number of water pipe rows to increase the heat dissipation of the radiator. In the actual design of automobile radiators, the improvement of the heat transfer coefficient of the tube-strip radiator should be considered from the aspects of optimizing the structural design of the radiator and improving the manufacturing process. Through the heat transfer wind tunnel test and numerical simulation study of a commercial vehicle tube belt radiator, according to the comparison and analysis of the simulation results, under the same working conditions, the double drain pipe type only increases the heat dissipation than the single drain pipe type. , While the wind resistance has nearly doubled, and the manufacturing materials have also nearly doubled. Therefore, considering the heat exchange performance, resistance performance, economy and reliability of the radiator, it is not the most effective method to increase the number of water pipe rows to increase the heat dissipation of the radiator.
