Title: Method and device for electrical discharge machining
Inventor: KATOU YASUYOSHI
IPC: B23H1/02
Filed: 1987-12-21
Abstract: PURPOSE:To effectively perform the machining of a straight deep hole by using an electrical discharge machining electrode having a suction port provided on an electrode supporting part smaller in diameter than the machining electrode, and making a fixed suction action during the descending stroke of a reciprocating motion. CONSTITUTION:Machining powder generated during machining is diluted with fresh machining liquid by the jumping action of an electrode 1 during its ascending stroke, and the concentration of the machining powder therefore lowers in a gap between the electrodes. The machining powder is next discharged together with the machining liquid from a space between the bottom of the electrode 1 and the electrode for a work 2 to a lower part of an electrode supporting part 3. The machining powder on the upper face of the electrode 1 and the machining liquid are drawn in by suction action made at this time from a suction port 4, and discharged through a suction passage 4a provided inside the electrode supporting part 3. Thus the smooth supply of the fresh machining liquid makes the effective discharge of the machining powder practicable even when a machined part has become deeper to improve machining efficiency.
