METHOD AND APPARATUS FOR TARGETED HIGH-VELOCITY FLUSHING OF AN EDM WORK ZONE

摘要

The velocity and method of delivery of dielectric flushing fluid through an electrical discharge machine work zone is sufficiently high so that the material of the workpiece adjacent to cut is not degraded in metallurgical quality. This is accomplished by utilizing flushing flow past the single point electrode tip at least about 75 inches/second. Substantially dielectric water can be used as the flushing fluid.
