电火花线切割加工是经两极间脉冲放电的电蚀现象来对各种形状以及轮廓的零件进行加工,注意此种加工方法并非依靠机械能来去除材料,而是依靠各种特殊能量形式(比如电化学能、电热能)来去除材料。实践表明,线切割加工既没有切削力,又能有效规避工件材料硬度的影响,因此被普遍用来进行各种材料的加工,往复走丝电火花线切割高效低损耗切割技术尤为重要。
The paper introduces the machining technology with the wire electric park cutting. There are not only disappearing the cutting force,but also not effect of workpiece hardness. So,the technology is used to work many sorts of material. Among a lot of such process,the wire reciprocating electric park cutting is the high efficiency and low consumption technology.
