Which your misoperation will lead to rupture of molybdenum w
Molybdenum wire speed is too low, which is also easy to break the wire because of pulling force, so as to improve the precision and cutting speed, and significantly decrease the broken wire, the tension and the speed of the wire as usual that tension in 12-15N is suitable.

The increase of the wire speed is beneficial to the molybdenum wire to bring the liquid into the discharge gap of the larger thickness workpiece, to ensure the removal of the electrical corrosion products and the stability of the discharge process.

It should ensure that molybdenum wire and conductive block, the workpiece and the work of the table to fight well, but the wire speed is too high, molybdenum wire should be changed back to stop soon, the guard cylinder will break transmission and molybdenum wire because of the inertia of the process.

Otherwise, the negative electrode of the high-frequency power supply can not be connected with the molybdenum wire, and if the drum is not cut off the high-frequency power supply, the cylinder can be connected and the guide wheel rotates to maneuver, and the stop block of the back end of the lucky wire cylinder needs to be adjusted.

Restrain the bobbin rushing from the limit stroke and break the wire. Otherwise, the vibration of the guide wire system will be broken when it is running back and forth, which will lead to the heating of the molybdenum wire in a short time because of the high temperature.

Therefore, it is necessary to check whether the stroke switch at the back of the bobbin is failed, whether the high-frequency relay is damaged or not, and the broken wires are related to the guide wheel and the conducting block, and if the guide wheel and the conducting block are produced by abrasion, the groove is formed.

Or the idler wheel bearing is worn to produce gaps, and it is easy to cause the molybdenum wire to shake and break the wire. The tension of the molybdenum wire can be improved, and the influence of the wire vibration can be eliminated.

The tension of the molybdenum wire will destroy the stability of the processing, the machining accuracy and appearance roughness of the city will be worse, and it will cause broken wires easily. The parts of the shaft and bearing of the bobbin are often caused by wear and tear, which causes the filament to shake and break the thread.
