Mitsubishi MV2400R / MX600

Contaminated dielectric fluid causes arcing instability, reduced cut speed, and surface quality degradation. Replace or treat the dielectric when conductivity and color fall outside the acceptable range.

EDM positioning drift causing part dimension errors is usually thermal expansion of the machine casting, encoder scale contamination, or worn drive components. Allow the machine to thermally stabilize before cutting aerospace parts.

Frequent wire breaks are usually caused by incorrect feed rate for the material and thickness, degraded dielectric fluid, or contaminated wire guides. Check flushing pressure and dielectric conductivity first.
