| The cutting of the middle thread increases the function of repairing the knife, and the knife is also the multi-knife cut that we often say. Generally, the first knife is used for cutting, and the next few tools are used for repairing the finish. Therefore, the smoothness that can be achieved by using the repairing tool is higher.
Since the wire is used for repeated discharge. When using the repairing tool function, as the cutting area increases, the wire drawing and the wire loss are more and more fine, which ultimately affects the accuracy of the work and the discharge and cutting effect of the last several times. In order to achieve high precision, the actual diameter of the molybdenum wire needs to be measured before starting the cutting. After the new molybdenum wire is cut after the guide wire is cut, the molybdenum wire is tightly tightened before the workpiece is officially cut. If the molybdenum wire has been used repeatedly for a long period of time, it is necessary to measure the diameter and roundness of the molybdenum wire. When the difference is too large, a new electrode wire must be replaced.
Pay attention to the following points when using repeated cuts:
1. When the molybdenum wire is empty, check the molybdenum wire for jitter.
2. Whether there is a cut mark on the surface of the conductive block, and whether the molybdenum wire is trapped in the conductive block.
3. Whether the flow rate and color of the working fluid are normal.
4, before processing, the process needs to imitate. Determine if the cut program generated by the system is true.
5, according to the characteristics of the data, the final cut of the remaining work as long as possible to reduce the impact of data distortion. |
