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 production of auto parts association

 

The formation of a professional and collaborative production pattern in the auto parts industry in Beijing has brought a series of benefits. First of all, professional collaboration guarantees the supply of coordinated parts for OEMs in Beijing. Specialized and coordinated production nearby can give full play to the geographical advantages and facilitate the various needs of the production and operation of the OEM. This includes various aspects such as quantity, variety, quality, transportation, and service. Second, professional collaboration has increased economic benefits for the country and enterprises.

Specialized collaboration has promoted the technological progress and management level of parts and components companies. In order to survive and develop, parts and components companies actively adapt to the market needs of mainframe manufacturers, continuously adjust products, actively develop new products, and carry out technological transformations. Through the adjustment of the product structure, the degree of specialization within the enterprise has been strengthened: for example, the degree of specialization of products such as jacks, glass lifters, and brake pumps have been strengthened. The above development is not only related to the enterprise’s own efforts, but also has a lot to do with the cooperation of management departments and OEMs.

Serious shortage of funds. The main reasons for the shortage are the shrinking production of enterprises, the reduction of sales income, the excessive proportion of the funds of reduced products in the fixed liquidity, and the large external debts of the enterprises, and some have no ability to repay. The speed of new product development is slow. First, the market forecast for development is inaccurate; second, the process tooling cannot keep up after the trial production of the new product, and the key technology is not good enough to form production capacity; third, the development speed of new accessories can not keep up with the host and the speed of modification . Due to protectionism in other provinces and cities, it is difficult to export the spare parts produced in Beijing, and the continuous entry of foreign products has caused the market to shrink. The decline in the economic efficiency of enterprises and the difficulty in exerting the production capacity of enterprises will inevitably bring about a decline in economic efficiency, and the macroeconomic recession has exacerbated this situation.
