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...

To further standardize and improve the production and supply of automotive lubricants in China

 

In every historical development stage of China’s automobile industry, Lanzhou Refining and Chemical Company Feitian Lubricant has given reliable guarantees. Up to now, China FAW Group Corporation has confirmed n types of “Feitian” lubricants as its supporting products; Dongfeng Motor Corporation has confirmed 7 types of “Feitian” lubricants for its factory loading oil and social service station oil; Many automobile production plants including Yuejin Group, China National Heavy Duty Truck, Chongqing Changan and Changhe have selected Feitian lubricants.

With the intensification of competition in the automobile market and the opening of the lubricant market, automobile manufacturers have decomposed the pressure to reduce costs to parts manufacturers, including the purchase of automobile lubricants, which invisibly buried the quality assurance of certain products. Potential crisis. Here are some misunderstandings in the selection of automotive lubricants and hope to be taken seriously. Brand-name cars cannot afford to use genuine lubricants, so they have to turn to local small blending plants to purchase. What must be emphasized here is that a few simple inspection qualification indicators cannot represent the intrinsic quality of the product. There are many examples like this. With China’s accession to the WTO, China National Petroleum Corporation established the China National Petroleum Corporation Lubricant Company to meet the challenge of major foreign lubricant companies to seize the Chinese lubricant market. The lubricant production and operation strategy of "Five Unifications, One Concentration" of the lubricant company’s "unified allocation of resources, unified product standards, unified network layout, unified price management, unified organization of scientific research, and concentration of power to highlight famous brands" will have a significant impact on the Chinese lubricant market. Play a strong role in promoting, which will undoubtedly further standardize and improve the production and supply of China’s automotive lubricants, so as to meet the requirements of the development of China’s automotive industry for lubricants.
