【摘要】 线切割通孔内轮廓零件,必须事先打穿丝孔,电极丝才能穿进去,才能进行加工。线切割精度高的外轮廓零件,也要预先打穿丝孔,从穿丝孔中心走丝进行加工,这样可以减少工件的变形,也可以防止电极丝卡住或拉断。穿丝孔位置确定的好坏决定零件加工质量和零件能否顺利加工。更多还原

【Abstract】 Outline of parts within a wire through hole, you must advance through hole,wire to fit in to be processed.High cutting precision of contour parts,or to advance through the hole from the wire hole wire processing,this can reduce the deformation of the workpiece can also prevent jammed or broken electrode wire.Wire hole position determinates the machining quality and smooth processing of parts.更多还原
