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...

The focus of lubricating oil competition

People in the industry know that, in terms of base oils and compound additives, domestically produced high-end oils are basically the same as well-known foreign brands, and there is almost no difference in quality. The focus of competition is mainly on market networks, services, and advertising. At present, in China, price methods still have great lethality for medium and low-end products and extensive market competition. However, in high-end products and mature market competition, product quality, brand and service have become decisive means of competition. .

The cultivation of the foreign brand marketing market attaches great importance to the construction of the sales network. It does not engage in general agent, implements an authorized dealer system, and implements authorization for a limited period of time. At that time, it will be re-examined and determined, and those that are not suitable for distribution will be eliminated. Each office can sell products to terminal distributors and direct supply users. Terminal distributors can deliver products directly to auto repair stations, auto parts stores, gas stations, franchised stores, fuel change centers, large fleets and large projects, etc. The market position is mainly high-grade oil, and vigorously increase the share of mid-range oil. The current domestic brand marketing market cultivation method is mainly through wholesalers, original equipment manufacturers, auto repair stations, auto parts stores, oil change centers and other channels for sales. Brand marketing is based on agency system. Lubricating oil manufacturers have set up agents in all parts of the country, and the products are distributed to specific users through agents. This form will last for a long time. As a brand, a scientific and standardized management system is required, and every step taken must be mobilized in an orderly manner under the guidance of general principles, rather than guerrilla-style actions.
