Working principle of slow wire processing

 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

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

What are the main reasons for the deformation of slow wire processing

 With the continuous improvement of slow-moving wire processing technology, people’s demand for it continues to increase. Nowadays, slow-moving wire processing technology is getting better and better, which has brought great help to our various product processing. In our life, the slow-moving wire processing procedures are very complicated and exquisite. If we want to be more precise, we recommend that we have a good grasp of its technical and technological knowledge. We will inevitably encounter various quality problems during slow-moving wire processing. Among them, the most frequent appearance is the deformed image, which often makes our manufacturers feel very headache. Then, how do we solve this situation? Let’s introduce for you.

Deformation occurs during the processing of slow-moving wire. In order to truly solve this situation, we must first find out the reason, then analyze it, and better deal with it. Then what is the main reason for its deformation? There are many reasons for the deformation, such as material problems, heat treatment problems, structural design problems, process arrangements, workpiece clamping and cutting path selection problems during wire cutting, etc. These reasons all lead to internal stress in the material. Transformation, we can deal with it from these aspects.

Also, the deformation of our wire EDM is related to the structure of the workpiece. The long and narrow shape of the concave mold and the convex mold are prone to deformation, and the deformation size is related to the complexity of the shape and the aspect ratio. Thin-walled workpieces are prone to deformation, these are very important details. Secondly, in our WEDM machining, the material will inevitably be deformed. If the deformation is extremely small, this deformation is almost negligible within the accuracy range of the processing requirements, but its deformation exceeds the processing accuracy requirements, which will cause obvious deviations in the size and affect the processing shape of the workpiece. We can take some measures to The deformation of wire EDM is controlled to prevent the occurrence of deformation.
