Because we use wire EDM machine tools are molybdenum wire to cut the workpiece, so the quality of the molybdenum wire has an impact on the quality of the products, efficiency and so on. So we must pay more attention to the purchase of molybdenum wire, to avoid buying poor quality products, so how can we buy good quality molybdenum wire.
First of all, you should buy the molybdenum wire produced by regular manufacturers as much as possible. There are also some famous brands, such as the molybdenum wire produced by Baoma in Suzhou, and the molybdenum wire of Guangming brand. The quality of molybdenum wire can be guaranteed absolutely. There is also the price, there is a saying that good goods are not cheap, cheap goods are not good, that cheap molybdenum wire you should be careful when purchasing.
Generally, when we check the quality of molybdenum wire, we should first see whether its quality is up to the standard. Then we can observe the wire running in use to see whether the tension is good, whether it is brittle, whether the wire breaking frequency is high, and whether the roughness of the workpiece is good. If all the above aspects are OK, Congratulations, what you have bought is good molybdenum wire, otherwise, what you buy is fake and inferior Products.
Another is that you can use a magnet to absorb. If the molybdenum wire is not magnetized to see whether it can be absorbed, it is adulterated molybdenum wire if it can be absorbed, and the melting point of molybdenum wire is very high. If it can be burnt out in 10 seconds, it is a fake. There is also the weight of molybdenum wire. If a mass of molybdenum wire is held very heavy in hand and falls on the ground with metal impact sound, it may be There's iron in it. We can refer to the above information to judge whether it is good or not.
