At present, many people are asking that cnc electric spark drilling machine always breaks wires, and the working fluid and wires are all new, but there are still problems of broken wires, which need professional answers to help solve. The main solution to such problems depends on the thickness of your cutting. And even if it is thin, it is necessary to see whether the power tube is opened too much, or the pulse width is too large, and the proportion of the working fluid is right, generally bad parts are easy to be found, so it is estimated that it is not caused by the reason of the broken parts, the damage of the parts will emit some abnormal noise, it is estimated that it is still the fault of high-frequency sound control. Slow down the number of steps and tracking, if it is always short, it will affect the life of the silk.

In fact, the problem of simple broken wire is a very serious problem in the processing of cnc electric spark drilling machine. It can make the processing stop but have to start from the beginning, wasting a lot of working time and destroying the integrity of the machining surface. At the same time, it also increases a processing difficulty when unmanned operation is achieved, and also hinders the development of wire cutting technology. Therefore, studying the causes of wire breakage and the methods to prevent wire breakage has always been an important topic in the research of wire cutting technology at home and abroad. Domestic and foreign research at a very early time, experts have noticed that the broken wire is usually a very close relationship with the increase of short circuit, they believe that the wire vibration and short circuit will cause the processing speed to decrease and increase the probability of broken wire, and then found that before the broken wire, the frequency of the put point will suddenly increase. Usually, the effect is good within the time, the university professor once said that the proportion of random distribution, so as to prevent the experimental device designed for the broken wire precursor signal has achieved very good results, and the research also shows that the broken wire of different types of pulse power supply their precursor signals are different, which can reflect the amount of energy input to the discharge gap. There will be a sudden increase in front of the broken wire, and the operation and use of the cnc electric spark drilling machine bed can be used as a precursor signal of the broken wire in principle. At present, our country has a cnc electric spark drilling machine device that takes some protective measures to eliminate the precursor of wire breakage.

After the problem of cnc electric spark drilling machine short wire, the University of Aeronautics and Astronautics also has a special processing laboratory to prove that they believe that the process of broken wire begins with the instability of the processing process, the processing instability promotes the discharge at one point, and the discharge will trigger the discharge in time. Therefore, it will cause local high temperature, so that the electrode wire is burned, which is the whole process of broken wire, to take effective measures to let it enter a stable state as soon as possible, is the way to solve the problem of broken wire.
