    Abstract: An electroerosive contouring wire-cutting apparatus using a distilled or deionized water machining medium of a specific resistivity controlled to be in a range between 102 and 105 ohm-cm, and having abrasive particles of TiC, TiN, B4C, BN, SiC, Al2O3 and/or SiO2 of for example a particle size in the order of microns for delivery by the medium to the machining gap. A high-frequency vibration of a frequency of 1 kHz to 1 MHz is imparted to the wire electrode traveling through the workpiece in a direction transverse to the wire axis to enhance the combined electroerosive and abrasive actions at the machining gap. The machining medium is delivered by a nozzle, retrieved at a collector, and separated into its liquid and solid components in a separator. After deionizing the liquid and extracting the machining products, the abrasive particles and deionized water are mixed and recirculated through the nozzle.
