Wire electric discharge machining apparatus |
摘要 |
A wire electrical discharge machine includes a wire bobbin 3 with a wire electrode 1 wound therearound; a fixing base 25 for fixing the wire bobbin 3 so that the wire bobbin 3 does not rotate; a guide pulley 23 for supporting the wire electrode 1; a rotating arm 21 for supporting the guide pulley 23 and for pulling out the wire electrode 1 from the wire bobbin 3 and rotating the wire electrode 1 about the wire bobbin 3; a sliding mechanism 24 for supporting the guide pulley 23 slidably with respect to the rotating arm 21, in correspondence with a winding position of the wire electrode 1 on the wire bobbin 3; and a braking motor 13 for driving the rotating arm 21. It is possible to disperse the wear of the wire electrode 1 and improve the machining rate and machining accuracy. Further, it is possible to improve the reliability and suppress an increase in cost.
