我院七○一教研室范广信副教授和研究生郭黎滨研制的线电极电火花电解复合加工新工艺及复合线切割加工用新型水基工作液于1987年7月30日在我院通过部级技术鉴定。线电极电火花电解复合加工是一种利用电能、热能和化学能等多能的加工新工艺。复合加工与电火花切割相比较,在相同的切割条件下,表面粗糙度可降低0.5～1级;复合加工的精度和线切割的精度相等;切割速度略低干线切割加工,当脉宽大于20ms 时切割速度则高于线切割加工。经过复合加工后的工件表面层应力小,不产生微裂纹,而且显微硬
Our hospital 701 teaching and research associate Fan Guangxin associate professor and graduate student Guo Limin developed wire electrode EDM new technology and composite wire cutting with a new type of water-based working fluid on July 30, 1987 in our hospital through ministerial technical appraisal. Wire electrode EDM composite processing is a use of electricity, heat and chemical energy and other multi-energy processing new technology. Compared with EDM, the surface roughness can be reduced by 0.5 ~ 1 under the same cutting conditions; the machining accuracy is the same as that of wire cutting; and the cutting speed is slightly lower. When the pulse width is more than 20ms When the cutting speed is higher than the wire cutting. After composite surface treatment of the workpiece surface stress is small, does not produce micro-cracks, and micro-hard
