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...

Talking about the construction of auto parts supply network

 

To establish a corresponding supply network, first of all, we must choose a good business partner, mainly based on the other party’s economic strength, supply capacity, parts source channels and creditworthiness. As the saying goes: “Shop around and don’t lose money.” Through long-term observation and business exchanges, introducing a competitive mechanism, and the survival of the fittest, we have identified several business units as fixed supply outlets. For accessories that are not ordered directly from the manufacturer, they are all supplied by these outlets. Secondly, these outlets are required to achieve high-quality, competitive prices, and be responsible for quality issues to the end. Third, these outlets can implement high-quality services, agency transportation or door-to-door delivery, which saves the trouble of lack of manpower and can request goods at any time. Fourth, regular settlements are adopted for these outlets, usually one to two months. This makes full use of inventory and reduces capital occupation.

Starting from the national conditions and factory conditions, boldly explore new ways to do a good job in the localization of imported parts. Our company's K256 Clas car is an old-fashioned truck produced in the former Soviet Union. This type of vehicle has always been a special vehicle for our company's Sanguiqiao Dolomite Mine. The purchase of the necessary parts requires a large amount of foreign exchange if imported from the Soviet Union, and the cycle is very long, which is very uneconomical. We have also made some attempts. We have imported a batch of original Claas parts from the factory contacted by the Ministry of Metallurgy and some units at the Heihe Port. The price is surprisingly high. According to the actual situation, starting from the factory and national conditions, it is completely possible to replace imported ones with domestic ones. In the process of localization, we established business contacts with the designated localization unit of the Ministry of Metallurgy. Now we need more than 97 Klass accessories are domestically produced, which basically meets the company’s production needs and saves foreign exchange.
