  • Electrode clamping system for sink-type electrical discharge machines
    Patent number: 6642469
    Abstract: An electrode clamping system for an EDM-sinking system provides a two-sided dielectric fluid supply to a clamped electrode by placing supply channels in both the fixed and movable parts of the electrode clamping holder. An automatic control circuit controls the flow of the dielectric fluid with reference to a contamination particle concentration in the gap between the electrode and the workpiece, and automatically reduces the flow to a value at which electrode vibrations disappear when changing from rough machining to fine machining.
