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...

Business ethics of accessory operators

The social effects of macro-runaways. Some operators lack business ethics and have a weak concept of the legal system. In order to pursue their own profits, they use all means, do not follow the law, rules and regulations, or even know the law and violate the law. This has aggravated the de-ordering of the market and caused unfair competition. Can not be effectively contained. At the same time, due to good benefits, parts sellers of different scales and different economic components flock to the parts sales market blindly, making the development of the auto parts sales industry in a blind state. This flow of social resources has exceeded the equilibrium point, causing some companies to sell Insufficient, even closed business. The surplus of sales outlets and the large backlog of inventory in some companies have caused waste of resources and made the results of resource allocation uneconomical. At the same time, a large number of abnormal economic and non-technical behaviors have caused many social problems. The outstanding performance is corrosion. People's soul corrupts the social atmosphere and breeds the soil that “looks at money”. The non-economic behaviors and non-technical methods of the market have seriously polluted people’s spiritual realm, leading to swindling, kidnapping, bribery, and corruption of the entire social organism.

disrupted normal market order and disrupted market prices. The fierce competition provides opportunities and markets for auto parts dealers and counterfeit and shoddy product manufacturers. They use sellers' request psychology to throw out counterfeit and shoddy products, so that they can enter the market through various channels and gain access to the market. Divination profit. The sale and use of counterfeit and inferior accessories has contributed to the deterioration of vehicle conditions, resulting in the early destruction of vehicles, affecting the normal order of transportation and production, and threatening the safety of the country and people's lives and property. For automotive parts and parts machining, PTJ Shop offers the highest degree of OEM service with a basis of 10+ years experience serving the automotive industry.
