34-39 TEHNOLOGII PRIN ELECTREROZIUNE CU ELECTROD TUBULAR ȘI FILIFORM PE MUCN (II)

DESIGN OF EDM TECHNOLOGIES WITH TUBULAR AND PHILIFORM ELECTROD ON MTNC (II) This paper deals with the technology of making holes drilled with Ø8 H7 and cutting a contour from a piece with a filiform (or wire) electrode on the MUCN. The first part explains the EDM principle and presents the advantages of using the method. In the second part there is presented the manner of realization of the above-mentioned processes, as well as the drilling of solid metal tube electrodes. It also describes the operating principle (by EDM) of a wire-processing machine tool with numerical control.

Keywords: EDM – Electrical Discharge, dielectric, GAP – interstice, scintillation, Dielectric flow, Implosion of the plasma bubble, wire-cutting, die sinking Cuvinte cheie: EDM – descărcare electrică, dielectric, GAP – interstițiu, scintilație, curgere dielectrică, implantarea balonului cu plasmă, tăierea sârmei, scufundarea matriței
