Due to possibility of adjusting of power descriptions of stationary arc digit in wide limits by a management the terms of external environment there is possibility accordingly to regulate quality of the processed surface of hardwares and speed of delete of material. Size treatment as variety of electromachining an arc has all of advantages the last and on an order more high performance. A rational application of size treatment of sheet-metal an arc domain is details by a size to 150 мм. Power descriptions of stationary voltaic arc allow to realize the wide spectrum of me-chanisms of destruction of metal from the size melting to evaporation. Experimental researches of power descriptions of stationary voltaic arc are conducted in the transversal stream of liquid in small gaps in the conditions of electromachining, executed on two modern methods, rotined that tension of magnetic-field of such arc on an order is high-er, than stationary arc in mid air. This is condition ability of stationary arc in the stream of liq-uid measuring плавить and evaporate a metal. In the process of treatment as a result of snap-chilling from the molten state and satia-tion the products of working liquid under the action of arc the surface of the got wares acquires the improved properties: durability, wearproofness and hardness. Technological descriptions of process (productivity, quality, firmness of instrument) are determined power parameters arcs which depend on the hydrodynamic parameters of stream of environment. The developed constructions of instrument form in an area the actions of digit optimum structure of stream (without breaks). The presented experimental graphs of the pro-ductivity and quality in the function of managing parameters of process can be utillized for the choice of the optimum modes of treatment. Typical technological processes of treatment of openings, in particular, variable cross-sectional, external contours of multi-layered details (package), attended pair present the spec-trum of possibilities of the use of the developed technology. Comparatively with base technology, treatment of the indicated wares a stationary arc provides the decline of labour intensiveness in 2-5 times, flow of recoupment of 0,5-2, high economic efficiency and energy-savings.
