在线切割机床的加工中，加工薄工件真象切豆腐一样，但是对于加工厚件就不是这样了。我曾经加工一个厚２００ｍｍ的注塑模的型腔，在电参数稳定的情况下，当钼丝顺时针方向旋转，工作液自上而下快速流动时加工尚能平稳。但当钼丝逆时针方向旋转工件液自下而上流动时加工很不稳 In the machining of on-line cutting machines, the machining of thin workpieces is the same as cutting tofu, but it is not the case for thick workpieces. I used to process a cavity of 200mm thick injection mold. When the electrical parameters were stable, when the molybdenum wire was rotated clockwise, the working fluid could flow smoothly from top to bottom. However, when the molybdenum wire counterclockwise rotation of the workpiece fluid flow from bottom to top processing is very unstable
