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...

There is no strict production standard for fake and inferior auto parts

 

For users, even if safety, environmental pollution and energy saving are not considered, counterfeit and inferior auto parts are very troublesome. Counterfeit and inferior parts do not have strict production standards and perfect inspection and testing methods. There are many hidden quality problems, short service life, and the frequency of failures during use is quite high. Failures occur every three days, and minor repairs occur in a few days. Overhaul not only causes certain economic losses to users, but also annoying.

The proliferation of counterfeit auto parts in the market is harmful to no benefit. It has caused huge economic losses and reputation losses to the national management departments, manufacturers, sellers and consumers, and seriously threatens the safety of people's lives and properties. In this case, counterfeit and inferior parts can make money by using other people’s brands and markets. With little input, high output, and small money, you can make a lot of money. The high profit makes some people stunned and unscrupulous to delve into how to produce fake and inferior auto parts. Some small businesses, handicraft workshops, and cottage industry workers do not work hard on the technology and quality of the products, but spend their money on opening up some relationships, finding some low-tech auto parts production, and then selling them under the brand of others. Under-brand companies with a little technical strength are targeting those imported auto parts or key parts with higher profits. Since the sales of fake and inferior auto parts are quite flexible, no matter how bad the quality is, there is no worries that there will be no sales. There is a huge distribution network of fake and shoddy cars all over the country, everywhere, everywhere, where there are cars, there are fake and shoddy auto parts.
