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

Classification of CNC Machining Occupation Levels

1. Blue-collar layer:   That is, CNC machining operation technicians, proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attributes: automated machine tools), understand automatic programming and simple maintenance of CNC machine tools (attributes: automated machine tools), such There is a large market demand for personnel, and they are suitable for operating workers of CNC machine tools (attributes: automated machine tools) in the workshop, but due to their single knowledge, their wages will not be much higher.   2. Gray collar layer:   One, CNC machining programmer:   Master the knowledge of 5 Axis CNC machining Aluminum   technology and the operation of CNC machine tools (attributes: automated machine tools), be familiar with the design and manufacturing expertise of complex molds (title: mother of industry), and be proficient in 3D CAD/CAM software, such as UG, GOOGLE PRO/E, etc. ; Familiar with CNC

Hydrostatic guideway of CNC machining lathe

The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state.   CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200   beryllium   copper   and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and lette

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.
