1. Cut as much as possible within the normal thickness range of the cutter.
As far as possible, it should be cut within the rated cutting thickness. The normal cutting thickness of the cutting machine is generally 60% of the maximum cutting thickness marked by the manufacturer. Cutting within this thickness range is to protect the cutting tip to a large extent.
2. Minimize perforation cutting.
Generally speaking, an important reason for the damage of the CNC plasma cutting machine is that the perforation, because the perforation, the molten steel will be sprayed to the cutting nozzle of the numerical control plasma cutting machine, thereby causing damage to the cutting nozzle of the numerical control plasma cutting machine. Therefore, if it is necessary to perform perforation cutting, it is better to use a drill to make a pre-drilled hole, so that the material starts from the pre-drilling when cutting, so that the molten steel can be reduced at the perforation to damage the numerical control plasma cutting machine. Cut the mouth.
3. Keep the distance from the cutting tip to the steel plate as constant as possible.
The distance from the cutting nozzle to the steel plate is generally about 3-8mm. Too far away, not only the power consumption is too large, but also the cutting penetration ability is reduced, and the electrode is relatively consumed, so that the electrode life is reduced; when it is too close, the nozzle is wasted. The service life of the nozzle will also decrease exponentially, and may even result in being burned off just after installation.
In summary: the service life of plasma electrode nozzles is related to other factors, such as the input voltage level, the quality of the electrode itself, the quality of the plasma cutting machine, the integrity of the equipment, and the quality of the plasma torch. , user's technical experience, etc. However, the three points mentioned above are the most important. After grasping these 3 points, the service life of the electrode nozzle will be greatly improved.
