本文讨论了我国现行的快速走丝工艺条件下,线切割的介质、电极损耗和切缝的几何形状等问题。使用去离子水配制的乳化液介质可以减少断丝、消除黑白交叉条纹,在成倍提高加工速度的前提下,从光洁度方面达到国外慢速走丝机床的质量水平。 This paper discusses the problems of wire cutting medium, electrode loss and the geometric shape of the kerf under the current rapid wire-drawing process in our country. The use of deionized water formulated emulsion medium can reduce broken wires, eliminating the black and white cross stripes, double in the premise of improving processing speed, finish from abroad to achieve the quality of the slow-speed silk-spinning machine.
