Since the high precision and quality of each processed workpiece directly depends on the high precision of the machine tool, it is necessary to check the running state of the machine tool before each processing, so as to provide conditions for obtaining high-quality processed workpieces. Links that need attention and measures to be taken as follows:

  (1)The electrode wire must be checked before processing. The tension of the electrode wire also has a great influence on the surface quality of the workpiece. For workpieces with high surface quality requirements, the tension of the electrode wire should be increased as much as possible under the premise of continuous welding wire.

  (2)Check the rolling state of the guide wheel, if the rolling is not good, please replace it. Carefully check the damage and dirt of the upper and lower nozzles, use cleaning fluid to remove dirt, and replace them in time if damaged.

  (3)It is necessary to check the wear of the conductive block, and clean it with detergent if it is dirty. When changing the position of the conductive block or replacing the conductive block, it is necessary to recalibrate the verticality of the electrode wire to ensure the accuracy and surface quality of the workpiece.

  (4)The medium wire machine generally uses the working fluid prepared by emulsified oil and water. The spark discharge must be carried out in a liquid medium with a certain insulating function. After the discharge is completed, the discharge gap quickly returns to an insulating state.

  (5)In order to maintain a stable power supply voltage. The instability of the power supply voltage will cause instability at both ends of the electrode and the workpiece, resulting in the instability of the breakdown discharge process and affecting the surface quality of the workpiece.

  Do not turn on the high-frequency power switch before the middle wire feeder is turned on, and the high-frequency power switch must be turned off. After the molybdenum wire trial run, the molybdenum wire enters the working state, in this case, the switch of the high frequency power supply can be turned on. After the switch of the high-frequency power supply is turned on, the voltage should be controlled, and the voltage should generally be controlled between 60 volts and 80 volts. At the same time, if there is a problem with the machine during use, the high-frequency power supply should be turned off immediately, the cause should be found out, and the rear should be cleaned up. be usable.
