Working principle of slow wire processing

by
 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?

by
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

by
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...

Auto maintenance and auto parts market are closely linked

cncmachining December 16, 2021

Illegal business During the repair process, some use inferior parts to pretend to be high-quality parts; some use inferior products to replace original high-quality parts; some disassemble and assemble parts of car A to car B of the same model, and collect parts updates from customers. Expenses; some use damaged parts, dismantled old parts to pass off as qualified products, etc., which has seriously damaged the image and social reputation of the auto repair market. For example, in January this year, an auto repair shop promised to replace a new body when it was repairing a car for a company, but the actual replacement was the body after the accident, deceiving users. All technical supervision and quality inspection institutes and stations, during quality supervision or quality follow-up inspection, if any violation of the above regulations is found, they shall be stopped immediately and reported at the same time.

The quality of the maintenance team is low. Vehicle maintenance requires high professionalism and skills, and has a large dependence on inspection and maintenance equipment. The characteristic of opening a business with a large number of one-time investment. In some developed countries abroad, once a car is repaired with quality problems or using inferior parts to cause an injury, the repair manufacturer will be caught in a lawsuit for high compensation and it is difficult to get out. As the nationwide pilot program for the professional market has just started in China, the legal system has yet to be improved. Some social organizations and even individuals who do not have sufficient conditions and capabilities hire repairers privately. Due to the low quality of the personnel, there is a serious lack of basic guarantees for the quality of repairs. If the distribution unit continues to sell products that are unqualified in random inspections and have not been re-examined (reported for inspection) for rectification, they shall be re-examined and punished once they are found. Low quality of auto parts. With the development of society and economy, the auto parts market has become an important emerging industry. According to incomplete statistics, there are about 40 auto parts stores in our city, and they are still growing. At the same time, the contradiction of many problems in the product quality of the auto parts market has become increasingly prominent. It is worth noting that car maintenance and auto parts market are closely linked.
