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 on the Treatment Countermeasures of Motor Vehicle Exhaust Pollution

1. Strengthen the household management of motor vehicles and implement total control of motor vehicles in accordance with the actual conditions of the city. Strictly control the increase of motor vehicles in urban areas. New cars need to be tested for exhaust gas to ensure that the exhaust gas meets the emission standards before they can go through the household procedures.

2. Strengthen the management and treatment of motor vehicle pollution sources. Establish a unified supervision and management agency for the purpose of controlling motor vehicle pollution emissions, formulate and promulgate relevant laws and regulations, strengthen the supervision and management of motor vehicle exhaust pollution, and strictly implement motor vehicle exhaust emissions Annual inspection, random inspection and road inspection, compulsory installation of purification devices or engine purification for vehicles with excessive exhaust emissions. Motor vehicles that have not been able to meet the emission standards after treatment are prohibited from driving on the road. Timely eliminate the overdue motor vehicles that consume a lot of fuel and cause heavy pollution. Strengthen the management and supervision of the vehicle maintenance and repair industry, and indeed implement decontamination and maintenance measures, and give full play to its due role.

3. Promote high-quality lubricating oil, and fully adopt unleaded gas oil. High-quality lubricating oil can increase the sealing performance of internal combustion engine cylinders, reduce mechanical wear, improve fuel combustion efficiency, and reduce the emission of harmful substances; the full use of unleaded gas oil can effectively reduce the engine The content of metallic lead in motor vehicle exhaust can reduce the pollution of urban air environment caused by motor vehicle exhaust.

4. Improve road facilities. Further open dedicated lanes for motor vehicles and non-motor vehicles in urban areas to improve the quality of the road surface to increase the speed of motor vehicles and reduce the emission of slow or idle pollutants from motor vehicles. At the same time, trees or grass can be planted on both sides of the road to enhance the ability of the road greening system to purify pollutants.

5. Deep people carry out environmental protection education and raise public awareness of environmental protection Make full use of media such as radio and television, newspapers and magazines to actively carry out environmental protection publicity, raise the public’s environmental awareness level and the protagonist's sense of responsibility, and consciously resist behaviors that damage the environment.
