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...

Market technical analysis of auto parts industry

The state has begun to strengthen macro control over the quality of auto parts, which has promoted the continuous improvement of product quality. For example, in 1992, the Bureau of Technical Supervision issued the “Implementation Measures for the Regulations of the People’s Republic of China on Product Quality Certification”, which was hosted by China National Automobile Industry Corporation, including experts from scientific research units, quality inspection agencies, and production enterprises, and established the China Automotive Product Quality Certification Committee . On behalf of the country, the committee implements quality certification for automotive products, and issues certification certificates, certification certificates, and certification marks. The establishment of the committee has played a catalytic role in improving product quality and reputation, promoting technological progress, ensuring the interests of users and consumers, ensuring personal safety, protecting the ecological environment, saving energy, and promoting international trade. Today’s auto parts market also has worrying problems, mainly including the following points: Compared with the production of complete vehicles, the production of repair parts is lagging behind. Some auto manufacturers are busy assembling new cars and are not on the agenda for the production of repair parts.

Many parts of joint venture vehicles have to be imported from abroad with a large amount of foreign exchange, resulting in long shutdown dates for maintenance vehicles and high maintenance costs. The quality of some parts of the domestically produced joint venture cars is not as high as that of some cars. However, according to users’ reports, some parts of the domestically produced parts are easily damaged. This is mainly due to the introduction of new technologies for vehicle manufacturing since the 1980s, while the parts manufacturing industry introduced fewer new technologies and lacked the necessary support policies. Therefore, domestic auto parts cannot meet the needs of new joint venture vehicles in terms of quantity and quality. Maintenance needs. The macro-control of the parts production industry is weak. The factories that are unable to produce auto parts have no unified technical standards. There are two machine tools and one thatched cottage to produce auto parts. There are no drawings and standards. They are copied with real objects, and the parts produced are not inspected. Get the market to sell, causing counterfeit and inferior auto parts to be repeatedly banned.
