Cutting of high thickness workpiece, especially high thickness workpiece above 800mm, is strict to all aspects. It is necessary to adjust the state of the machine and start cutting. Adjustment of the machine status including:
First of all, checking the stability of the wire system, mainly to ensure that the guide wheel and bearings are in good working condition, observing the electrode wire running without obvious jitter by the eyes;
In addition, checking the upper and lower conductive blocks are in good contact with the electrode wires;
Third, in order to reduce the influence of unilateral loose wire, keeping the electrode wire covered with 1/2~1/3 of the wire cylinder, choosing the brand electrode wire with the diameter is more than 0.18mm, and choosing the JIARUN series working fluid with great performance;
Fourth, choosing large pulse width such as Ton>100µs and the duty ratio is 1:8~12, processing current is about 3A; Fifth, adjusting frequency tracking from slow to fast according to the processing situation, until the current table pointer stability.
