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

“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.
