CNC Coolant Troubleshooting Guide

This Coolant Troubleshooting Guide helps with the proper maintenance of CNC coolant. It is essential to ensure optimal machine performance and longevity. However, even with regular maintenance, coolant failures can occur. That’s why this guide is invaluable in identifying and correcting these failures.

Below you will see a visual reference system that makes it easier to identify coolant failures. The system categorizes issues as either high or low value. High-value issues can cause severe damage to your machine and require immediate attention. On the other hand, low-value issues are still important to address but need to be more critical to address. Regular maintenance can effectively manage these.

Coolant Troubleshooting Guide Factors:

One of the most common coolant failures is a foul odor emanating from the coolant. This failure can often be attributed to inadequate management of tramp oil and pH levels. To fix the issue, it is important to regularly remove excess oil. Also, you will need to oxygenate the liquid when not in use, and closely monitor the pH levels. Neglecting this issue can lead to other problems, such as split emulsions, rust, and skin sensitivity.

Another common failure is the presence of foam in the coolant. This can lead to various issues, including reduced lubrication, corrosion, and decreased tool life. When a failure occurs, it is often caused by either excessive agitation or high coolant temperatures. In order to address the problem, monitor the temperature of the coolant, decrease the amount of agitation, and use defoamers as necessary.

Other common coolant failures include discoloration, bacterial growth, and sediment buildup. The breakdown of coolant additives or the introduction of contaminants can cause discoloration. Bacterial growth is often the result of insufficient maintenance, such as irregular skimming or inadequate filtration. A lack of filtration or excessive contamination typically causes sediment buildup.

You may also be experiencing other problems that are caused by the same neglect, such as split emulsions, rust, and skin sensitivity.
