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

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

Spring Design Attention And Roll Forming Method

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

Minimal lubrication processing helps increase cutting speed

The cutting tool cuts the metal by breaking the metal layer.The fracture of the metal layer means that the external force destroys the metal structure and at the same time releases the internal energy of the metal in the form of heat.During cutting, on the one hand, the chips transfer the heat of the crack to the surface of the cutting tool. On the other hand, the chips are pressed into contact with the cutting tool by bending stress and move relatively quickly to generate frictional heat. The combined reasons make the cutting tool and the metal surface The temperature rises rapidly.During the cutting process, the high-heat solid metal will be rapidly cooled by the quenching effect of the cutting fluid to produce a quenching effect, which destroys the crystal phase structure. At the same time, the molecular dislocation in the crystal phase increases, making the metal hard and fragile at the same time .When the cutting tool finishes cutting and leaves the workpiece, the hot tip will contact the coolant to produce a “quenching reaction” that makes the cutting tool hard and fragile, especially the coated cutting tool, which affects the life of the cutting tool.Since the intensity of the quenching effect is proportional to the temperature difference, increasing the cutting speed will make the cutting tool higher temperature, and the strong quenching reaction produced by the greater temperature difference will further reduce the life of the cutting tool.This is why the higher the cutting speed, the shorter the life of the cutting tool.

During micro-lubrication processing, the lubricant is sprayed onto the machined surface in the form of mist particles, which will not produce quenching or quenching effect. Moreover, when the cutting speed is increased, the cutting fracture point of the workpiece will appear in advance, and the heat source of the fracture point will be far away from the knife. tip.Since the heat is all concentrated on the workpiece and chips,
The heat source of the cutting tool is only a small part of the heat conduction and friction at the contact point of the chip. Increasing the cutting speed will cause the chip to bend and leave the workpiece and cutting tool at a faster speed, effectively reducing the time for the chip to conduct heat.The high temperature remaining on the workpiece can soften the surface of the workpiece and make the cutting tool easier to cut.Therefore, in general, micro-lubrication processing is suitable for increasing the cutting speed.
