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

Use MEP electromagnetic oil pump to solve the problem of cold start and make some discussion

 

Modern power electronics technology. The defense industry uses electromagnetic fuel pumps to improve the cold start of vehicles. The cold start of vehicles has always been a problem that many domestic automobile manufacturers and users often pay attention to and research. The cold start problem of vehicles involves many factors. This article discusses the use of MEP electromagnetic fuel pump to solve the cold start problem.

General vehicles, especially diesel locomotives, are more difficult to start under the climatic conditions of minus 20-40°C in northern China. Although diesel locomotives have a preheating device, the amount of oil delivered by the mechanical oil pump is determined by the mechanical frequency. When idling, the mechanical frequency is not high. In addition, due to the low temperature, the retardation of diesel increases. In addition, mechanical pumps have many oil seals, which are easy to leak, etc., so the oil volume cannot keep up when starting at low temperatures and cannot be exhausted quickly to purify the oil circuit. In recent years, the series of electromagnetic fuel pumps developed by Shanghai Jiaotong University and produced by Shanghai Guangyin Communication Electric Industrial Company have solved the above problems well. The MEP electromagnetic oil pump is produced by using new materials and new technology. It adopts modular working mode. It is small in size, high in power, and easy to assemble. The most important thing is that the series is complete, the reliability is good, and the continuous work can reach more than 2000h. Many indicators are Exceeds the Japanese JISD industrial standard. In recent years, it has been used well on some large and medium-sized vans and military vehicles, and has been widely welcomed by users.

In addition, since the power source of the electromagnetic oil pump is fundamentally different from that of the mechanical pump, its use under normal circumstances also brings many benefits. For example, the oil circuit of some large vehicles can be lengthened, which is conducive to frequent starting of the vehicle, and it is not easy to stall when the vehicle is climbing. Electric exhaust is far more convenient than manual exhaust. Of course, for gasoline cars, the air resistance can be greatly reduced in summer. In short, MEP electromagnetic oil transfer pump has many advantages over mechanical pumps. As long as the reliability of electromagnetic oil transfer pump is recognized by the market, its application prospects should be very broad.
