在线切割加工中,经常会碰到这样二种情况:1.工件高度超过支座到上线架的距离,例如SCX—73型,此距离为70mm,如实际加工的工件大于70mm,而小于80mm(即不超过两线架间的跨距)。2.被加工的工件装夹余量少,(或工件形状特异,无法用压板),因机床线架的宽度较大,而使工件难以加工,例如J01758B—CNC1型单边加工余量最小应在10mm以上,以至使小的模具无法装夹。针对这二种情况,我们采用如下方法:先把夹具(见图)放在平板上用
In the online cutting process, two kinds of situations are often encountered: 1. The height of the workpiece exceeds the distance from the support to the upper bobbin, for example, SCX-73, the distance is 70mm. If the actual workpiece is larger than 70mm and smaller than 80mm That is, no more than the span between two wire shelves). 2. The workpiece is less workpiece clamping margin, (or workpiece shape, can not use the platen), due to the larger width of the machine frame, leaving the workpiece is difficult to process, for example, J01758B-CNC1-sided machining allowance should be minimal Above 10mm, so small mold can not be clamped. For these two cases, we use the following method: first fixture (see Figure) on the flat with
