电接触切割金属不同于其他切割方法之处是,可用简单的力法荻得较高的生产率,使用廉价工具和用水做工作介质。电接触切割过程有以下特征:形成特殊的残余热应力和工具(圆盘—电极)变形;在切割带上电弧发生顺序空载现象,此时无金属从被切零件上剥落下来;因稳定的水气弥散系统的作用,从切割带上析出了冷凝的片状微粒;加工大截面零件时,金属微粒从切割带上散出是个复杂过程。现在常用低碳钢(10号钢、CT3)制成光滑圆盘,做为电接触切割的旋转工具。使用
Electrical contact with cutting metal is different from other cutting methods is that a simple method can be obtained Di Di higher productivity, the use of cheap tools and water as the working medium. The electrical contact cutting process has the following characteristics: the formation of a special residual thermal stress and tool (disk - electrode) deformation; the arc in the cutting tape sequence occurs no-load phenomenon, when no metal from the cut parts peeled off; due to stable Water and gas dispersion system, from the cutting tape condensation of the flake particles; processing of large cross-section of the parts, the metal particles from the dicing tape is a complex process. Now commonly used low-carbon steel (No. 10 steel, CT3) made of smooth disc, as the electrical contact cutting cutting tool. use
