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

Analysis of Energy Structure of Gas Locomotive

Adjust the energy structure to solve the problem of tight oil supply and high prices. At present, the price of liquefied gas and natural gas is much lower than that of gasoline, and when the “West-East Gas Pipeline” project is completed, cities along the route will have sufficient natural gas resources. Reduce the impact of cars on urban air pollution. Under the same technical conditions and working conditions, the emission of gas vehicles is much better than that of gasoline vehicles. Therefore, urban development and promotion of gas vehicles can reduce the pollution of the city's atmosphere by vehicles. The air purification project initiated by 13 ministries and commissions in April 1999? “Clean cars in action” activities accelerated the development of urban gas vehicles.

At present, the number of CNG and LPG gas vehicles in all parts of the country has been rising sharply, and this boom is still heating up. However, in the process of promoting gas vehicles in various places in the past two years, various problems have appeared. Not only did they fail to achieve the desired energy saving and pollution reduction goals, but also caused new energy waste and air pollution. In view of the problems that have emerged in the past two years, this article discusses several issues that should be paid attention to in the development of gas vehicles in cities. The technology of gas vehicles is not yet mature. Among the gas vehicles promoted in China in the past two years, a more serious problem is that each pilot city spends most of its power on the transformation of vehicles (accounting for nearly 80%), while ignoring the development and development of gas vehicles. Production (only 20%). Although the modified car is simple and easy to use, it can be used immediately, but the disadvantages far outweigh the advantages. Whether it is economical, environmentally friendly, or the performance of the vehicle itself, the situation is not optimistic.
