线切割经常遇到须外径定位而加工内型腔的工件,因为打火花找正难达到同心度要求,所以只好制造一块工艺板,在板上切出定位孔,费工又费料。我设计制作了一种通用夹具,圆柱及圆台工件,均可用外圆定位。调整和使用方法如下:(见示意图) Wire cutting often encountered outside diameter positioning and processing of the cavity of the workpiece, because sparks find it difficult to meet the concentricity requirements, so had to create a technology board, cut holes in the board positioning, laborious and costly materials. I designed and manufactured a universal fixture, cylindrical and truncated workpieces, all available cylindrical positioning. Adjustment and use as follows: (see diagram)
