What is the reason for the white sparks of high-frequency wire cutting? Wire cutting machine source manufacturer [Zhikai CNC]
The whitening of high-frequency sparks during wire cutting is a common phenomenon, mainly caused by the high-frequency sparks generated during wire cutting. Wire cutting is a metal cutting processing method that uses the principle of electric spark discharge. The principle is to melt the metal on the surface of the workpiece through the electric spark discharge between the electrode and the workpiece, thereby achieving the purpose of cutting.
There are many reasons for the whitening of high-frequency sparks in wire cutting, mainly including the following aspects:
1. The gap between the molybdenum wire and the workpiece is too large.
During wire cutting, the gap between the molybdenum wire and the workpiece is a very important parameter. Too large a gap will lead to unstable current and produce excessive sparks.
2. The molybdenum wire is severely worn.
Molybdenum wire is one of the most important parts in wire cutting, and its wear will directly affect the quality of wire cutting. When the molybdenum wire is severely worn, the current distribution will be uneven, resulting in excessive sparks.
3. The surface of the workpiece is uneven.
Wire cutting uses electric spark discharge to melt and evaporate the metal on the surface of the workpiece. If the surface of the workpiece is uneven, the current distribution will be uneven, resulting in excessive sparks.
4. Cutting speed is too fast.
The cutting speed of wire cutting is an important parameter. If the cutting speed is too fast, the current distribution will be uneven, resulting in excessive sparks.
To solve the problem of whitening of high-frequency sparks during wire cutting, the following measures can be taken:
1. Adjust the gap between the molybdenum wire and the workpiece. A reasonable gap can make the current evenly distributed, thereby reducing the generation of sparks.
2. Replace the molybdenum wire regularly. Severe wear of the molybdenum wire will cause excessive sparks, so it is necessary to check and replace the molybdenum wire regularly.
3. Improve the flatness of the workpiece surface. Improving the flatness of the workpiece surface through processing and grinding can reduce the generation of sparks.
4. Control the cutting speed. Reasonably control the cutting speed to make the current evenly distributed, thereby reducing the generation of sparks.
In short, the whitening of high-frequency sparks during wire cutting is a common phenomenon in the wire cutting process. There are many reasons for its occurrence, but through reasonable adjustment and control, the generation of sparks can be effectively reduced and the quality and efficiency of wire cutting can be improved.
