至今为止,各单位关于线切割加工中断丝原因的分析,不外乎是机械精度,高频电源,冷却液特性,变频调正这几个方面。我们在实践中基于下面的事实发现:当上述几方面都正常时,工件的材料问题也会引起严重的断丝。例如:加工两种不同材料,第一种材料加工很顺利,当同样条件下加工第二种材料时,即 So far, all units on the wire cutting fault analysis, nothing more than mechanical precision, high frequency power, coolant characteristics, frequency conversion correction of these aspects. In practice, we have found based on the following facts: When the above aspects are normal, the material of the workpiece can also cause serious broken wires. For example: processing two different materials, the first material processing is very smooth, when processing the second material under the same conditions, namely
