The heat resistance of metal molybdenum is higher, so spraying molybdenum wire can also be used to repair the worn parts after surfacing. Of course, in modern wire cutting power supply, wire cutting molybdenum wire has put forward more stringent requirements, Molybdenum wire must be able to withstand more than 700 amperes peak or average cutting current greater than 45 amperes, and energy transmission must be very effective, so as to provide for high surface finish cutting products on the high frequency pulse current of more than 0.2Ra in the required, and make the line cutting equipment and molybdenum wire produce high-quality products. The tensile strength of wire cutting molybdenum wire is the ability to measure the resistance to fracture when the material is subjected to radial load. Therefore, the higher the strength is, the better the ductility is. This is difficult for the production line cutting molybdenum wire manufacturers again. The elongation of molybdenum wire is the percentage of the change of wire length caused by tension and heat in cutting process. The thermal physical characteristic of the wire electrode is the key to improve the cutting efficiency.
The melting point of wire cutting molybdenum wire is an important index of EDM. Because of the mechanical movement of the electrode wire through the guide wire, as well as the factors such as flushing force and discharge, the wire of the electrode wire is vibrating when cutting. This will result in numerous minimal short circuits that slow down the cutting process. When the electrode wire is working, if it can be lost on the outer diameter, the gap in the face of the cut can prevent or reduce the short circuit effect. The special status of wire cutting molybdenum wire in processing is briefly described.
