We know that EDM is the electrolytic erosion of workpieces, while electrochemistry is the use of electrolyte to dissolve the workpieces. Relatively speaking, EDM is now very popular. For example, in precision mould  manufacturing, EDM is an important art. However, some technical misunderstandings in the mold factory will cause the CNC EDM to fail to meet the expected accuracy, surface, and efficiency requirements. Let's analyze and explain these common problems. 1. When the electrode hits the workpiece to be centered, it often misses The method of using the electrode to directly touch the workpiece belongs to surface contact. There are inevitably more or less fine objects between the contact surfaces, and there are also clamping accuracy errors on the contact surfaces, which will directly affect the accuracy of edge finding and centering. With this method, the contact surface must be strictly required to be wiped clean, but due to the presence of human factors, the accuracy will be

With the acceleration of commodity economic circulation, cargo handling has become the most concerned operation link in logistics. Increasing labor costs and improving the efficiency of cargo turnover have placed higher demands on the logistics industry, and mechanized automation has become a trend in the industry. As the smallest container unit, pallets can be used in conjunction with forklifts, stackers and other equipment in logistics handling, and they are more and more widely used. Plastic pallets are favored by food, medicine, chemical industry, cold chain and other industries due to their own advantages of non-toxic, odorless, acid and alkali resistance, neat appearance, no nails and no thorns. Pallet mould supplier tells you how to buy plastic pallets? What issues should be paid attention to when choosing plastic pallets? First, choose according to your own usage scenarios Different companies have different application scenarios, and the scope of application of pallets is diffe

Users who use O ring have found that O-rings have aging problems very early in the process of use? Sometimes O ring do not reach the service life under normal conditions at all! Why is this? Causes O ring aging What are the reasons? Next, Jiadong will introduce to you. O ring aging is very common in life, but if the aging is very serious, then you should pay attention to it, it may be the problem of your use. Under normal circumstances, O ring aging is related to 4 factors: 1. Ozone: The chemical activity of ozone is much higher than that of oxygen, and it is more destructive. It also breaks the molecular chain, but the effect of ozone on rubber varies with rubber deformation. When used as deformed rubber (mainly unsaturated rubber), cracks in the direction of stress action, so-called "ozone cracks" appear; when acting on deformed rubber, only an oxide film is formed on the surface without cracking. 2. Light: We all know that the shorter the light wave, the greater the energy

The O ring must be assembled according to the correct requirements before use to ensure that its sealing effect can be fully utilized. At present, imported O-rings are widely used in automobiles, water conservancy and construction production machinery. Not only are they safe and environmentally friendly, but the unification of their production standards also promotes the expansion of the application market of O-rings. But it should be noted that when using environmentally friendly O ring, more attention should be paid to the details of the installation process. The main points that need to be paid attention to when using O-rings are as follows: When installing the O-ring, keep the installation environment clean, especially to prevent dust from entering the installation part. If hard particles enter, it is likely to cause serious damage to the surface of the O-ring during operation, thereby reducing the overall use of the product Life, surface material damage will also increase the int
