Ordinary fast wire cutting machine, cutting a knife, directly cut the workpiece. But the middle walking process imitates the slow walking process. When cutting the first knife, reserve 5% - 10% boss to prevent the workpiece from falling down, and then carry out a knife repair. In the process. The system software will change the parameters, and adjust the wire speed to the corresponding speed by reducing the parameters and high frequency. Then the process of slow wire trimming is imitated. Finally, the boss is cut. If the boss also needs the corresponding trimming, it will imitate the slow wire cutting process, plug the rest of the cut gaps with copper, and then stick them with 502 glue, and then repair the boss, so that a complete workpiece can be obtained.
In order to realize the trimming function of WEDM, firstly, the system can automatically jump parameters, and the system must support the trimming function. If not, it is not advisable to switch parameters manually. Secondly, the need for high-frequency power supply can be switched to smaller parameters, the need for frequency converter can achieve the conversion of wire speed. When the cutter is repaired, the rotation speed of the wire is adjusted to be smaller and smaller, so that the molybdenum wire runs more and more smoothly, and a better finish can be achieved.
