Wire length is one of the most important factors in CNC hot wire cutting – and the most frequently underestimated. Many buy the largest possible machine and wonder about poor cut quality. The answer is almost always the same: the wire is too long. Short wires run more stably, vibrate less and produce cleaner surfaces.
Wire lengths that are too long reduce cut quality, accuracy and speed. Why shorter is almost always better in hot wire cutting – and when long wires still make sense.
