CNC Plasma Table Water Treatment

As CNC plasma table operators, we have experienced the challenges that come with maintaining the quality of the water used for cutting. Water is an essential element in the plasma-cutting process, as it cools down the material and removes debris.

However, if the water used for cutting is not properly treated, it can lead to several issues, such as poor cutting quality, damage to the machine, and health hazards. That’s why CNC plasma table water treatment is so important. 

To keep the best CNC plasma table at its peak performance, just follow the steps for CNC plasma table water treatment below.

CNC Plasma Table Water Treatment

Over time, the water used for cutting will become contaminated with debris, such as metal shavings, oil, and grease. This contamination can and will affect the quality of the cut, as it can cause the torch to drag and leave rough edges. Moreover, if the contaminated water is left in the CNC plasma table for an extended period, it can damage the machine by clogging the plumbing and the filters.

In addition to affecting the quality of the cut and damaging the machine, contaminated water can also pose health hazards to the operators. The debris in the water can produce harmful fumes when exposed to the high temperatures of the plasma torch, leading to respiratory issues and other complications.

Implementing a Simple System for CNC Plasma Table Water Treatment

To mitigate the above-mentioned issues, we have implemented a water treatment system for our CNC plasma table. This system involves several steps to ensure that the water used for cutting is clean and free of contaminants. Being mindful and prepared will keep your machine in tip-top condition and will save you from the headache of having to repair it later on.

Install a proper filtration system

The first step is to install a filtration system to catch and remove larger debris, like metal shavings and particles, from the water. The filtration system consists of a series of screens that trap the debris and prevent it from entering the machine. This step is crucial, as it prevents the larger debris from clogging up the plumbing and filters, which can damage your machine.

Use plasma water treatment chemicals

The second step is to add chemicals to the water to remove oil and grease. Oil and grease are common contaminants in the water used for cutting, and they usually come from the material that is being cut. These contaminants can be hard to remove with just a filtration system, which is why chemicals are used to break them down. Aside from breaking down bacteria and grease, they also act as corrosion inhibitors, which will keep your machine running at its best.

Monitor the pH level of the water

The third step is to monitor the pH level of the water. Plasma cutting generates a lot of heat, which can cause the pH level of the water to rise, leading to corrosion of the machine’s internal components. To prevent this, we regularly test the pH level of the water bed, usually every two weeks, and adjust it with the proper chemicals if necessary.

Replace the water occasionally

The final step is to occasionally replace the water in the water bed of the plasma table. Even with proper filtration and chemical treatment, the water will eventually become too contaminated for use. We replace the water in the plasma table once a month or so to prevent it from forming any unwanted by-products, and with proper filtration and water treatment, it could even last longer than that.

Make sure to properly dispose of the replaced water. Check your local state regulations, so you know how to dispose of contaminated water correctly. Using a proper chemical solution will keep your water clean and, if replaced regularly, can be safe for municipal sewer dumping.

Cost Considerations

When considering implementing a water treatment system for your CNC plasma table, you need to be aware of the costs involved. There are three main areas where costs can come into play: equipment, chemicals, and maintenance.

For the equipment, the cost will depend on the type and size of the system you choose. A basic filtration system might only cost a few hundred dollars, but a more complex system that includes UV sterilization or chemical treatment could cost several thousand dollars. You need to choose a system that makes sense, one that meets your needs while fitting your budget.

The chemicals used in the water treatment process could also be pretty expensive. The type and quantity of chemicals will depend on your specific CNC plasma table. One of the do’s of managing CNC tables is consulting with your supplier for an adequate chemical mixture for your machine.

Be sure to choose a chemical solution that is environmentally safe, and that will keep your equipment running at its best.

Regular maintenance is necessary to keep a water treatment system functioning properly. This can include replacing filters or membranes, cleaning and sanitizing equipment, and monitoring water quality. These maintenance tasks can require the use of specialized tools and equipment and be performed by trained professionals.

In general, keeping your CNC plasma table properly sanitized and maintained will keep costs down in the long run.

Conclusion

Implementing a water treatment system for a CNC plasma table can significantly improve the quality of the cuts and extend the lifespan of the machine.

In conclusion, maintaining the quality of the water used for cutting in a CNC plasma table is essential for achieving high-quality cuts, extending the life of the machine, and providing a safe working environment for the operators and any personnel around it. By implementing a water treatment system that includes filtration, chemical treatment, pH monitoring, and regular water replacement, operators can ensure that the water used for cutting is clean and free of contaminants.

As CNC plasma table operators, we can attest to the benefits of implementing such a system and highly recommend it to others in the industry.
