Plastic mold parts are mainly used in the manufacture of plastic molds, high precision requirements, mold materials should have a high tempering resistance stability, then plastic mold parts in the use of spark is normal?
Plastic mold parts with sparks, plastic mold parts with sparks is the possibility of conductive bad wear, change a face or change a position can be. Another possibility is that the plastic mold parts are installed too low, so that the molybdenum wire seems to contact non-contact, adjust the plastic mold parts up a little to ensure good contact can be. In addition, pay attention to the quality of plastic mold parts. General plastic mold parts are carbide wear-resistant, but once the discharge will soon go down.
Plus short circuit, if it is the processing process of molybdenum wire and workpiece frequent short circuit, then it is tracking too fast. If how to adjust can not, then look at the concentration of water, and then can not be a tracking circuit problems, need to repair. After cutting the workpiece will be like this, because the water is very difficult to enter the processing point inside. The key in this case is to ensure that the water into the processing point than the adjustment works better, the pulse width does not need to be special, according to your common line, such as 50-60; pulse between to be large, to do more than 10 back it. In addition, the guide wheel jitter a little will also make the slit wider, the processing state is better, huh, and then there is the cutting fluid selection drainage effect is good. This may be related to the direction of flushing, molybdenum wire from the top down when the water is brought into the slit by the molybdenum wire, so the discharge state is good; molybdenum wire up when the flushing water is not good, the internal discharge in the dry discharge state, go fast and slow. Adjust the flushing water. In addition, try the tension of the wire when the barrel is on the left and on the right, and check whether there is a one-sided loose wire state.
