POSITIONING METHOD AND DEVICE FOR FORCELESS ELECTRICAL EMISSION DISINTEGRATION

摘要

Devices and methods for eroding pilot holes and the like by positioning an erosion electrode in a location corresponding to a pre-cut in a material are disclosed. A collar or extended end of a hand held erosion device with ground and erosion electrode within said collar is placed in a pre-cut and sealed against a workpiece. A dielectric flushing fluid is added to the workpiece when electrical energy is applied to the electrode for erosion.
