Operation method for preventing electrode wire from breaking in wire cutting

The invention relates to an operation method for preventing an electrode wire from breaking in wire cutting. The operation method comprises the following steps: a proper molybdenum wire and reasonable tension thereof are selected; the movement reversing times of the electrode wire are reduced; a winding mode of winding the molybdenum wire on a wire winding drum is changed; the rotating flexibility of a wire storage cylinder and a guide wheel is kept; the proper cutting speed is selected; stable flushing conditions and the cleanness of cooling liquid are kept; and the voltage stability of a power supply and the cleanness of the cooling liquid are kept. The method operates the steps to realize no-wire-breaking operation, to realize automatic operation and to bring convenience to operators, is more intelligent in operation, keeps the voltage stability of the power supply and the cleanness of the cooling liquid to prepare the operation and effective operate to prevent the wire breaking, guarantees the processing continuity, wastes no work hours, can protect the processing surface completeness, and realizes unmanned operation and automatic operation.
