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 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.
