Description
technical field [0001] The invention belongs to the technical field of special processing, and in particular relates to an ultrasonic vibration rotating magnetic field assisted micro electric spark processing device and method. Background technique [0002] Hole processing is a processing technology with a relatively large proportion in mechanical processing, accounting for about one-third of the total mechanical processing. In hole processing, it is especially difficult to process small holes and deep holes. Especially in recent years, materials have developed in the direction of high strength and high hardness. It is often necessary to process small holes and deep holes on some difficult-to-machine materials, such as military high-energy explosive black Sorkin's step-by-step detonation holes, high-pressure common rail diesel engine nozzles, satellite axisymmetric engine nozzles, space vehicle diversion and heat dissipation holes, and embedded nose cone micro-flow holes, et...
