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

The advice of the CNC master, you must do this for CNC, otherwise you will not be able to get ahead!

    Think about it before 2008, when the post-70s generation wanted to enter a similar factory, they had to ask acquaintances, treats and gave gifts. What now? On the other hand, no young people want to enter the factory as workers anymore, and the bosses can't get up anymore, licking their faces and telling all the good things, even coaxing and cheating, it is difficult to recruit people.
     In the past, 90% of the urban residents in China's coastal cities were the children of workers, but these people are no longer working at all, and young people in the suburbs also despise being workers. Even if they have no way, they have to find a freelancer in the factory. Management position, half-hearted messing around. A large number of small and medium-sized manufacturing industries are in a bad world today. The reason they can barely maintain is because there are a group of migrant workers born in the 60s and 70s who are supporting them. The motivation for working hard is that their children will never go to the factory as workers, which can change the destiny of the family.
If it takes another ten years, when these people retire or can't do anything, there will be no workers in the manufacturing workshops.


     Now the post-80s and post-90s, the main purpose of working in the factory is to find someone to fall in love with. By the way, they can learn a little bit and are not interested in learning professional and technical skills at all. This group of people has no chance, they have lost their ideals, they are desperate, and they will give up before they get rich. Plan your own path well and don't follow your feelings.
     Young cnc machining parts engineers should make arrangements according to their personal ideals. Most people do not expect to become academicians or professors, but hope to live more moisturized and refreshed lives. Then, you need to carefully arrange your own trajectory. In which industry you should start with, which products to make, gradually get a deeper understanding of the industry. Don't change jobs frequently, especially don't change positions for a little salary. In the long run, this little money is nothing at all. When you have so much knowledge about an industry After several years of experience, money will not be a problem at all in the future. Frequent turbulence is not the best policy. In the end, you have no idea about any industry, and you will always be a novice! You can do technology, don't indulge in technology, don't devote yourself to technology!
     Don't be a master of machining uhmw technology, just be a master of comprehensive quality!
In a company, we often look down on someone, saying that he "knows nothing, why do you get so much money, why do you get promoted! This is a common and typical engineer's pedantic words. Is Zhou Gong Zhao Gong very good? People who can go up must have his abilities, and they are abilities you don't have.
    Think about it, the boss has been in business for so many years, is it not as knowledgeable as you, a recruit? People may be good at management, good at understanding the boss's intentions, good at department coordination, and so on. Therefore, you must cultivate your own abilities in many aspects, including management, affinity, ability to observe words and expressions, and research skills. To become a master of comprehensive quality, you have a bright future, otherwise you can only hide in the corner and become a "Green Key Man"! Skills other than technology are more important! !
    Make friends of all kinds and don't think that you have a common language and only communicate with CNC engineers. In fact, the more important thing is to interact with other types of people. If you want to be a boss or senior management one day, then these are the people you face all day long. Understanding their experience, thinking habits, hobbies, learning their problem-solving patterns, and understanding the phenomena and problems in all corners of the society are huge capital for future development. Without these, they will be clumsy, stumble, and encounter many difficulties.. ....
     Knowledge is not necessarily specialized, but it must be broad, read more books in other areas! Finance, accounting, import and export, taxation, law, etc., do some accumulation for the future, and the future will be more useful!
      Seize the opportunity to transform to plastic machining technical management or marketing. If you want to have a future, you can't continue to develop. If you want to change to management or sales at an appropriate time, the future will be even greater. The technology was not used in vain before, and it will be used in the future. Got it. Engage in management can cultivate one's own leadership ability, engage in sales can cultivate one's own market concepts and thinking, and at the same time accumulate a huge network of contacts for one's future development!
