一、前言目前电火花线切割机床使用的工作液为乳化液。分析DX—1乳化液中含有10号机械油为73％;航天502—1乳化液中含有10号机械油79％和蓖麻油3.5％。我们研制的工作液是以水为基本成分的新型工作液。这种工作液在不影响切割速度的条件下,加工粗糙度可从R_α6.3降低到R_α3.2或R_α1.6,同时还可节省油料,降低成本。 I. Preface At present, the working fluid used by WEDM is emulsion. Analysis DX-1 emulsion containing 73% of the mechanical oil; Aerospace 502-1 emulsion contains 79% of the No. 10 mechanical oil and castor oil 3.5%. The working fluid we developed is a new working fluid based on water. This working solution does not affect the cutting speed of the conditions, the processing roughness can be reduced from R_α6.3 R_α3.2 or R_α1.6, while saving fuel and reduce costs.
