the main reason of edm short circuit
1: the roller bearing wear large jitter molybdenum wire,
2: cutting fluid is dirty difficult chip removal ( replaceable water-based cutting fluid ),
3 : frequency tracking too quickly may be appropriate to reduce the cutting speed,
4: high frequency parameter is set properly,
5: the important point if the machine will not be able to cut through unilateral high workpiece, the total short-circuit phenomenon edm filter
