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 bett...

What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th...

Introduction of KOVAR parts

KOVAR parts are commonly used as metal casing materials in the electronic packaging industry. Because they have a linear expansion coefficient close to that of molybdenum group glass, and can produce less sealing stress during the sealing (melting) process with molybdenum group glass, so To obtain good air-tightness, in order to make the metal tube and shell to achieve air-tight sealing, in the entire sealing process, the annealing process undoubtedly plays an important role as a link between the previous and the next. The internal stress generated during KOVAR  machining also prepares the material structure for the implementation of the subsequent process-the sealing process of the metal parts. The main purpose of annealing Kovar shell before sealing is to: (1) Eliminate machining stress. When Kovar undergoes plastic machining deformation during cold working, about 10% to 15% of the applied energy is converted into internal energy, which is commonly referred to as internal stre...

“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.
