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

“Registration Measures” to promote the development of the automobile market

The research report of the automobile registration method is reported by the Policy Research Association of China Automobile Manufacturers Association. Among them, the motor vehicle registration certificate with the function of the property right certificate can not be carried with the car, so in principle, it is not possible to conduct reselling fraud. This will not only reduce the car rental price, but also relieve the worries of many companies that want to start a car rental business, which is conducive to the development of the car rental industry. The Association of Automobile Manufacturers or the Association of Automobile Manufacturers will provide compensation to the demanders. The information is provided by the traffic control department for a fee. The “Registration Measures” laid a solid foundation for this statistical work.

Conducive to improving the quality of automobile products and promoting technological progress_Currently, China's policies and regulations are insufficient in promoting the quality of industrial products and technological advancement. Article 50 of the “Registration Measures” stipulates that the vehicle management office can entrust large-scale state-owned automobiles and motorcycles. , The exclusive sales store of the agricultural transport vehicle manufacturer shall handle the registration of the inspection-free motor vehicles produced by the enterprise on behalf of the vehicle management office. The specific measures shall be formulated separately. Only cars with good quality can be exempted from inspection, and cars with exemption from inspection can save vehicle inspection fees before registration. At the same time, dealers can directly apply for car licenses, which can save users the cost of entrusting motor vehicle registration and save money for car users. and time. Therefore, the sales of inspection-free vehicles in specialty stores will inevitably be better than those of non-inspection-free vehicles. It will effectively promote automobile manufacturers to improve product quality, speed up technological progress, and strive for vehicles to meet the inspection-free level as soon as possible.

is conducive to speeding up the process of automobile tax and fee reform. The issuance of motor vehicle registration certificates and the computer networking of motor vehicle registration management in the future provide convenience for the accurate statistics of various domestic motor vehicles according to equipment quality and engine displacement. Therefore, it provides a prerequisite for the future integration with international conventions and the implementation of vehicle tax. The implementation of vehicle tax is conducive to reasonable taxation, thereby promoting the development of the automobile market.
