Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much better t
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
We all know that CNC lathe processing thin wall is more difficult, especially the processing of the inner hole, because in the cutting process, thin wall by the role of cutting force, easy to produce deformation.Lead to appear thus ellipse or middle small, two ends big "waist shape" phenomenon.In addition, due to the poor heat dissipation during processing, thin-walled casing is easy to produce thermal deformation, resulting in errors in size and shape.The important problem to be solved is how to reduce the influence of cutting force on the deformation of the workpiece. Next, HW Precision Technology will take you to explore the skills of CNC lathe processing of thin-walled parts.
Numerical control lathe processing of thin-walled parts is a more difficult problem in turning processing, the reason is that thin-walled parts of poor rigidity, weak strength, very easy to deformation in the processing, so that the shape and position error of parts increase, not easy to ensure the processing quality of parts.Using the characteristics of high machining accuracy and high production efficiency of numerical control lathe, and considering the effect of technological problems on the machining quality of parts, the experiments on the clamping of the workpiece, the geometric parameters of the cutting tool and the programming of the program were carried out to overcome the deformation of thin-walled parts in the process of machining effectively.The machining accuracy is guaranteed, which provides a good basis and reference for better processing of thin-walled parts in the future.
No matter what form CNC lathe machining parts, the first must start from the view of the part diagram.The figure shows that the thin-walled parts processing, easy to produce deformation, here not only clamping is not convenient, but also the parts to be processed that is difficult to process, the need to design a special thin-walled casing, shaft protection.
