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
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
Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs · Installation space: When designing a compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam
(1) High hobbing speed <br /> Generally, in dry hobbing processing, the linear speed of the coated (TiAlN) high-speed steel hob is required to reach 180m/min or even higher; for the hard alloy steel rolling The cutting speed is required to reach 300 m/min.In order to realize this high-speed hobbing processing, the tool spindle can generally be realized by an electric spindle; for the worktable, a new-designed gear transmission system with automatic clearance elimination is used to replace the traditional worm and worm gear transmission system, LIEBHERR, GLEASON The worktables of high-speed gear hobbing machines of other companies have adopted torque servo motor technology, and the worktable speed can reach more than 800 r/min.
(2) Quick separation of chips <br /> Due to the high temperature, if the chips cannot quickly leave the tool, workpiece and machine tool, it will easily cause thermal deformation and affect the machining accuracy. Therefore, iron chips must be removed quickly and effectively.In dry hobbing, the high-speed hobbing of the hob is generally used to make the iron filings quickly leave the tool and the workpiece.In response to the chip removal problem, many companies have also proposed some machine tool structural improvements, such as using gravity to speed up the removal of iron filings, and avoiding the iron filings from directly falling on the workbench, and then assisting with high-pressure cold air to achieve rapid and effective chip removal.Some companies also use stainless steel heat shields. On the one hand, the surface of stainless steel is smooth, which facilitates the removal of iron filings. On the other hand, the heat conductivity of stainless steel is small, which reduces the heat transfer of iron filings to the workbench and bed.
(3) High-speed hobs <br /> The hob materials for dry hobbing use cemented carbide steel in the early stage of development. However, due to the high cost of cemented carbide steel hobs, the powder metallurgy high-speed steel hobs developed in recent years and TiAlN coated high-speed steel hobs have a tendency to replace hard alloy steel hobs for dry hobbing.In a research report, Liebherr Company has performed the processing of hard alloy hob (Carbide) dry hob, powder metallurgy high-speed steel hob (HSS-PM) and conventional high-speed rigid hob (Conv.HSS). The time and processing cost are compared.The comparative analysis results show that, compared with conventional machining, dry hobbing has shorter processing time and lower cost; the use of powder metallurgy high-speed steel hobs has even better dry hobbing results than the use of cemented carbide steel hobs .
