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
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 the function of cutting at constant linear speed, so it can not only cnc machine parts with small and uniform surface roughness, but also suitable for turning parts with different surface roughness requirements. Generally, the machining accuracy of CNC lathes can reach 0.001mm, and the surface roughness Ra can reach 0.16μm (precision CNC lathes can reach 0.02μm).
Parts with small surface roughness values
The precision CNC machining numerical control lathe has a constant linear speed cutting function, which can machine parts with small and uniform surface roughness values. The problem is that the surface roughness depends on the feed rate and cutting speed when the material, the finishing allowance and the tool have been determined. The cutting speed changes, resulting in inconsistent surface roughness after turning. Using the constant line cutting function of the CNC lathe, you can choose the best line speed to cut cones, spheres and end faces, so that the surface roughness values after turning are small and consistent. .
Parts with complex surface contour shapes
Because the precision titanium machining CNC lathe has linear and circular interpolation functions (some CNC lathes also have some non-arc curve interpolation functions), it can turn complex shapes composed of arbitrary straight lines and various flat curves. Body parts, including list curves that cannot be described by equations that are processed by fitting calculations. As shown in Figure 4-1, the molding surface of the closed cavity of the shell part cannot be machined on an ordinary lathe, but it can be easily machined on a CNC lathe.
