Mistakes of WEDM in CNC EDM

Many people claim that wire cutting improves machining accuracy and smoothness, and claims to replace wire cutting. I discuss with experts in the industry that it is pure nonsense. Because the displacement deviation caused by the commutation of the molybdenum wire that restricts the fast-moving wire is not solved, it is impossible to greatly improve the accuracy, because after the commutation of the molybdenum wire, the molybdenum wire has gone out of its original position, and the cutting accuracy cannot be less than the insurmountable error of these fixed wires. Instead, it is believed that multiple cuts in the middle wire will reduce accuracy.

At present, most of the manufacturers who claim to improve the accuracy are non-mainstream manufacturers. The national standard is to cut 28 square meters with an error of 15um. Now it is generally credible to achieve 10um. At least I believe in the higher accuracy.

Indicators: The indicators that can be seen in the publicity are still Shanghai Tello. The samples I got impressively read that the processing accuracy is less than 0.3um. According to this precision and his extremely price, most of the slow-walking wire manufacturers should close their doors and go home to buy molybdenum wire.
