线电极电火花电解复合加工新工艺和线切割用水基工作液,于一九八七年七月在哈尔滨船舶工程学院通过鉴定。在线切割机床上应用电火花电解复合加工新工艺,切割速度不降低,但表面粗糙度下降(表面光洁度提高0.5～2级)。切割速度V_(wi)≥18mm~2/min时(脉宽t-i=8μS),R_a≤1μm(▽7),V_(wi)≥35mm~2/min时,R_a≤2.5μm(▽6)。而且表面层应力降低了1/2～ Wire electrode EDM new technology and wire cutting water-based working fluid, in July 1987 in Harbin Institute of Shipbuilding identified. On-line cutting machine tool EDM composite processing of new technology, cutting speed is not reduced, but the surface roughness decreased (surface finish increased by 0.5 to 2). R_a≤1μm (▽ 7) and R_a≤2.5μm (▽ 6) when the cutting speed V_ (wi) ≥18mm ~ 2 / min (pulse width t-i = 8μs) and V_ (wi) ≥35mm ~ 2 / min. And the surface layer stress reduced by 1/2 ~
