How to maintain the CNC plasma cutting machine?

Plasma arc cutting requires high precision to ensure that a high-quality cutting edge is obtained. Inspection and cutting patterns play an important role in the overall setup of the plasma industry. Therefore, robust preparation, cutting and maintenance can help solve a variety of troublesome problems faced by most operators.

This passage is going to talk about the followings of CNC cutting machine:

1) Replace wear parts regularly

2) Use the right components for each job

3) Check proper gas and coolant flow

4) Conclusion

1) Replace wear parts regularly

Regular oil changes are essential to avoid the replacement costs associated with purchasing a new system. Likewise, it is more cost effective to replace wear parts on a regular basis than to replace the entire torch. Continuous use of finished and obsolete wear parts can interfere with the normal arc in the plasma assembly and lead to unexpected torch failures.

What are the common signs of obsolete consumables? Poor cut quality is a clear sign of component wear. Experts recommend a daily visual inspection. Replace nozzles when oxidation residue is present and there are signs of air planning inside and outside the nozzle.

Check for pitting of the electrode elements and check for overuse of the electrode. The user guide helps to check whether the electrode replacement is ideal. If you are using oxygen, the pitting depth should not exceed 3/32 in. Nitrogen and Argon should be higher than 1/8 in. Gas swirls that show signs of cracks, burns, and dirt particles should be replaced promptly.

2) Use the right components for each job

The choice of consumables for the CNC cutting machine depends on the plasma gas and cutting current used for each job. The operator's manual helps to define the different types of consumables suitable for each type of cut. Not using the specified consumables will shorten the life and quality of the components.

Each part in the CNC cutting machine system must be run at the correct amperage with the nozzle set at 95%. Too low a current strength will result in inconvenient cutting, while too high a current strength will shorten the life of the nozzle.

3) Check proper gas and coolant flow

It is highly recommended to check the gas and coolant pressure of the CNC cutting machine daily. Inadequate flow rates result in improper cooling of consumables. This can have a significant adverse effect on the part involved. Smooth and programmed air pressure is important to maintain the cutting arc. Hard starts are a common problem associated with high air pressure, and the CNC cutting machine's torch will not work properly when all other conditions are working properly.

The cleanliness of the CNC cutting machine is critical and the plasma gas must always be dry and clean. Contaminated gas can lead to premature torch failure and shortened wear parts life. the CNC cutting machine's compression system is most likely to be affected by contaminated air.

4) Conclusion

With proper operation and maintenance, plasma arc systems can help reduce the cost and time spent on the job site. In addition, proper operation increases the durability and high cut quality of the system. Regular maintenance can reduce the time spent cleaning metal before it enters the manufacturing process.
