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 better t

Classification of CNC Machining Occupation Levels

1. Blue-collar layer:   That is, CNC machining operation technicians, proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attributes: automated machine tools), understand automatic programming and simple maintenance of CNC machine tools (attributes: automated machine tools), such There is a large market demand for personnel, and they are suitable for operating workers of CNC machine tools (attributes: automated machine tools) in the workshop, but due to their single knowledge, their wages will not be much higher.   2. Gray collar layer:   One, CNC machining programmer:   Master the knowledge of 5 Axis CNC machining Aluminum   technology and the operation of CNC machine tools (attributes: automated machine tools), be familiar with the design and manufacturing expertise of complex molds (title: mother of industry), and be proficient in 3D CAD/CAM software, such as UG, GOOGLE PRO/E, etc. ; Familiar with CNC

Elimination of Gear Backlash in CNC Machining Feed System

Elimination of Gear Backlash in CNC Machining Feed System   The transmission gear in the feed system of the CNC machining machine tool must eliminate the transmission gap between the meshing gears as much as possible, otherwise the motion will lag behind the command signal after each reversal of the feed system, which will affect the machining accuracy (accuracy) ). There are the following two common methods for CNC machining machine tools to eliminate the transmission gear gap.   1. Rigidity adjustment method   The rigid adjustment method is an adjustment method that cannot be automatically compensated for the tooth side clearance after adjustment. Therefore, the pitch tolerance and tooth thickness of the gear must be strictly controlled, otherwise the flexibility of the transmission will be affected. This adjustment method has a relatively simple structure and a better transmission rigidity.   (1) Eccentric shaft adjustment method   As shown in Figure 610, the gear 1 is mounted on th

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.
