(1) the abbreviation that line cut machines electric spark of numerical control of line cut —— . (2) working principle: The wire that uses shift makes tool electrode, connect between tinsel and workpiece with pulse electric current, use what pulse discharges to corrode action to undertake to workpiece cut is machined. (3) what use as a result of it is filar electrode, accordingly, can make outline cut treatment only. (4) working principle is shown 2 times like the graph. Pursue the of treatment principle of machine tool of 2 lines cut 1 - - numerical control device 2 - - Chu Sijian 3 - - guide pulley 4 - - electrode silk 5 - - workpiece 6 - - nozzle 7 - - insulation board 8 - - pulse generator 9 - , both between produce scintilla to discharge namely and cut workpiece. (6) the statement that issues through L of numerical control device, control pace enters electromotor 11, two splint of drive X, Y are mobile, can process the work that takes up the post of meaning curve outline.
