Abstract
In wire-cut electrical discharge machining apparatuses that simultaneously perform a plurality of cutting processes by engaging a wire between main guide rollers at a plurality of times, a wire-cut electrical discharge machining apparatus is provided that suppresses vibrations at cutting wire sections, to enable the cutting processes under steady-state accuracy. In addition to the main guide rollers, vibration-damping driven guide rollers or vibration-damping guides are included which form a plurality of cutting wire sections where the vibrations are suppressed by guiding the wire into place, and the positions of the cutting wire sections are thereby defined with respect to nozzles.
