How to prevent deformation during slow wire processing

 Slow-moving wire processing is a very exquisite and exquisite craft, and sufficient preparations need to be made, so that the processed products can be more quality. The slow-moving wire processing technology has a wide range of applications and is a must in our industries. If you want to do better with less technology, you must master all aspects of the processing knowledge. For example, the most common thing is the deformation during processing.  How can we solve it How to prevent deformation during slow wire processing Speaking of slow wire processing, it uses continuously moving fine metal wires as electrodes. Pulse spark discharge is performed on the workpiece, where it generates a high temperature above 6000 degrees. Moreover, if it wants to improve its quality problems and prevent its deformation, it can firstly start from the following aspects. 1. To prevent deformation, it is impossible for the material to have no internal stress. In particular, the internal stress of the que

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

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 than those of the fast-moving wire cutting machine, so in the processing of high-precision parts At the time, the slow walking wire cutting machine has been widely used, in addition to the early small and medium-sized enterprises, it is also extremely common in the processing plants of large enterprises such as aviation, automobiles, and medical treatment.

Slow-moving wire is a processing machine tool that uses continuously moving fine metal wires (called electrode wires) as electrodes to perform pulse spark discharge ablation and cutting of the workpiece. There is between the online electrode and the workpiece during slow-moving wire processing. The phenomenon of loose contact light pressure discharge, when the flexible electrode wire and the workpiece are close to the generally considered discharge gap (for example, 8-10μm), no spark discharge occurs, even when the electrode wire has contacted the workpiece, it can be seen from the microscope When the gap is not reached, sparks are often not seen. Normal spark discharge occurs only when the workpiece is bent and offset by a certain distance (a few micrometers to tens of micrometers). At this time, the wire electrode feeds 1 μm every time. The discharge gap does not decrease by 1μm, but the wire electrode increases the tension between wires a little bit, and the workpiece increases a little bit lateral pressure. Obviously, only a certain slight contact pressure between the wire electrode and the workpiece can form a spark discharge. There is an electrochemically produced insulating film medium between the electrode wire and the workpiece
