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...

It is very important to extend rural auto parts outlets

 

Extending sales outlets and opening up the rural market is an important business decision in the auto parts sales industry since the reform and opening up. The vigorous development of county-level companies and business offices in the same city has achieved significant results, broadening the sales market, expanding coverage, increasing sales, and improving corporate and social benefits. It is warmly welcomed by the majority of car users. The maintenance parts needed by car users below the county level must go to the prefectures and cities to purchase according to the administrative divisions. Users often travel long distances to purchase one or two kinds of accessories, which consumes a lot of manpower, material resources and time.

With the development of the rural commodity economy and the rise of township and village enterprises, the number of agricultural vehicles is increasing. The number of vehicles used by county citizens has increased from a dozen or dozens of vehicles before the reform to hundreds or thousands of vehicles. In rural areas, the original auto parts sales outlets have not been able to meet the needs of the development of rural automobile transportation. The majority of auto users have asked auto parts sales companies to set up sales outlets in counties so that they can buy the necessary parts nearby. Based on the needs of the development of the market situation, in accordance with the requirements of the China Automobile Sales and Service Company to gradually extend the sales and service outlets to the county at that time, the practice of one year has further deepened the company’s understanding of the necessity and urgency of extending sales outlets. Decided to include the work example of the extension of the outlets on the important agenda.

Practice has proved that self-organized outlets can really play the role of occupying the market, expanding coverage, and stabilizing sales positions. Especially in the case of open market, multiple operations, and fierce competition, if you want to expand sales and improve efficiency, you can only establish yourself Only the point of sale has a foothold. At the same time, self-managed sales points are also conducive to the unified management of the business, so that the provincial, prefectural, and county three-level companies form a unified sales group, which can give full play to the role of the main channel. Associated points and agency sales points are difficult to achieve the above goals. Once they are mature in business and economic conditions, they will often get rid of the main channel, establish themselves and become competitors in the sales market.
