Abstract
The article reflects possibility of a heightening of productivity and improvement of quality of
process ESA at usage of impulses with energy less than 0,5 J. In a bottom of the offered solution waiving
of conventional philosophy of forming of the spark channel encounter by a treating electrode and detail.
The tendered electrode system ensures an opportunity of feeding of impulse at any moment of time, allows to
implement requirements of forming of the spark channel by explosion of contacting asperities of adjoining
electrodes were in continuous driving from each other (slide of a electrode on a detail) in one plane.
The enumerated results of study productivity, roughness of formed coverages.
