AUTOMATED WIRE-CUTTING SPARK EROSION MACHINE Russian patent published in 2010 - IPC B23H7/02 B23H7/26 

FIELD: technological processes.

SUBSTANCE: invention relates to the field of metal treatment, in particular to devices for spark erosion cutting of metal with wire electrode-tool. Automated wire-cutting spark erosion machine comprises device of program control of drives of horizontal crossing displacements of table 2 with processed part 3 and/or bracket 4 with wire electrode-tool 5, drilling head 9, installed on upper arm 8 of bracket 4 with the possibility to displace rotary drill 10 parallel to displacement of wire between arms of bracket, and axis 11 of drill is located relative to wire electrode tool at fixed distance, specified by coordinates of horizontal displacements of bracket and/or table and drilling head is equipped with drive of vertical displacement controlled by device of program control. Machine base comprises header for liquid dielectric and used wire.

EFFECT: invention makes it possible to reduce labour intensiveness of parts manufacturing and to increase accuracy of holes positioning to insert wire electrode-tool in process of spark erosion treatment of inner part surface.
