How to adjust molybdenum filament tightness can you break filament not easily?
It is well known that the tightness of molybdenum wire is very important. The tightness of the wire cutting molybdenum wire has a certain relationship with the processing efficiency, finish, and the precision of the workpiece. It can be said that the tightness of the wire cutting is very important. Usually we are tight according to their own experience and feel, can be tight out of a very good degree, the processing effect is also very good, so how is the tightness of molybdenum wire appropriate? Such as thick workpiece, short workpiece, hard material, soft material how tight? Don't worry. Let's go into the details.
First of all, we need to understand the relationship between the tightness of molybdenum wire. Compared with the tightness of molybdenum wire, the loose molybdenum wire can carry more current. Because the molybdenum wire is drawn thin, the resistance will be large, and the current of molybdenum wire is also easy to break. The tight molybdenum wire relative to the loose molybdenum wire, it is more stable, not easy to shake, not easy to stick knife, cutting surface finish will be better.
So according to the above principle, we can probably know that when we cut the high parts, the molybdenum wire can be relatively loose, because if the molybdenum wire is too tight, the current of cutting the high parts is easy to burn the molybdenum wire, and the low parts can be slightly tighter than the high parts.
So hard material, soft material is actually not very easy to distinguish. Generally speaking, it depends on the material, for example, cutting copper, copper is a kind of soft material, but because of the characteristics of copper, we suggest that the molybdenum wire is tight in cutting, copper is not good in cutting chip, too loose molybdenum wire is easy to get caught together with the workpiece to cause short circuit. Stainless steel is a hard material, but its characteristics are easy to stick knife, we also suggest that the molybdenum wire a little tighter. Therefore, whether it is hard material or soft material, it is not said to be divided according to the tightness, only that there is a corresponding tightness.
Good tightness according to the material, parameters, wire cutting fluid, molybdenum wire bearing current and other aspects of the attempt, in order to get the most suitable molybdenum wire tightness, which is to distinguish between wire cutting master and wire cutting general conditions.
