How to reduce the consumption of wearing parts of CNC plasma cutting machine

Many CNC plasma cutting machine operators know that if the CNC plasma cutting machine cutting nozzle is damaged, it is easy to cause the plasma to not ignite. To avoid this situation, when using the CNC plasma cutting machine to cut the nozzle, pay special attention to how to use it. Only to protect the CNC plasma cutting machine cutting nozzle.
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. In addition, there are other factors that affect the life of the CNC plasma cutting machine cutting nozzle. For example, electrodes, such as voltage, in addition to the equipment problems of the CNC plasma cutting machine itself and other equipment problems, the operator's own proficiency in the CNC plasma cutting machine also determines the service life of the CNC plasma cutting machine cutting nozzle.

In addition to paying attention to the use of the cutting tip, we should also pay attention to the maintenance work of the torch:

1. Correctly assemble the torch

Install the torch correctly and carefully during the installation of the CNC plasma torch to ensure that all parts are well matched to ensure gas and cooling airflow. Installation Place all parts on a clean flannel to prevent dirt from sticking to the parts. On the O-rings with appropriate lubricant to the O-ring becomes bright subject, can not pay more.

2 . Consumable parts should be replaced in time before they are completely damaged. During use, do not replace consumables such as cutting nozzles and electrodes until they are completely damaged, because severely worn electrodes, nozzles and swirl rings will produce uncontrollable plasma arcs. It is very easy to cause serious damage to the torch. Therefore, when the quality of the cut is found to be degraded for the first time, the consumables should be inspected in time.

3 . Clean the connecting threads of the torch. When replacing consumables or routine maintenance inspections, be sure to clean the internal and external threads of the torch. If necessary, clean or repair the connecting threads.

4 . Clean the contact surface between the electrode and the nozzle. In many torches, the contact surface between the nozzle and the electrode is a charged contact surface. If there is dirt on these contact surfaces, the torch will not work properly. Hydrogen peroxide should be used for cleaning. Agent cleaning.

5 . Check the gas and cooling gas every day, check the flow and pressure of the gas and cooling air flow every day, and if there is insufficient flow or leakage, stop the machine immediately.

6 . To avoid torch collision damage, in order to avoid torch collision damage, it should be correctly programmed to avoid system over-limit walking, and the installation of anti-collision device can effectively avoid the damage of the torch during collision .

Secondly, for a detailed understanding of the cutting range that the CNC plasma cutting machine can withstand, the operator must not cut beyond the cutting thickness that the CNC plasma cutting machine can withstand.
