5 Best Practices for Managing Your CNC Coolant Fluid
When it comes to managing your CNC coolant fluid, there are several best practices that you should follow. The last thing you want is for your CNC machine to run inefficiently, leading to costly delays and repairs.
Whether you’re just starting with CNC machining or have been in the business for years, these five best practices for managing your CNC coolant fluid can keep your machines running smoothly.
Monitor Sump Levels Regularly
Monitoring the volume of your coolant fluid in the CNC sump is essential to ensure that proper cooling and lubrication are getting to the tooling and workpiece. The temperature of the coolant is most noticeable during the hot months of the year. Water evaporation causes an increase in coolant concentration, and sump volume is reduced. Thick coolant reduces cooling at the tooling and creates slime and build-up on windows, materials, and tables. Make sure to check the sump volume when starting and finishing the day. Always replenish as needed.
Change Filters Regularly
Your CNC coolant fluid needs to be filtered periodically to remove particles that can accumulate over time. It’s important to change the CNC coolant filter regularly, as they become less effective at filtering out impurities and get clogged with dirt and debris. Clean filters also help reduce wear on pumps and other parts of your CNC machine that rely on coolant fluids.
Keep the Tank Clean
Clean the tank where your coolant fluid is stored regularly with your coolant supplier’s recommended cleaning agent. Make sure to rinse thoroughly with clean water and run the CNC pump to flush the coolant delivery lines and nozzles. It is often recommended to flush the CNC with a small dilution of fresh coolant before doing a full charge of clean coolant as well. Cleaning the tank will help prevent and remove bacteria growth and buildup, which can lead to a shorter sump life for the coolant.
Check pH Levels Often
It’s important to check the pH level of your coolant fluid regularly to ensure it is balanced for optimal performance. An abrupt change in pH could show itself as issues with mixing, water, the operator’s skin, paint peeling, or staining of parts.
Dispose of Old Fluids Responsibly
When disposing of old coolant fluids, always use a reputable company specializing in hazardous waste removal services. These companies will safely dispose of old fluids and follow local laws and regulations for hazardous waste disposal. Remember, cradle to grave. Where the dirty fluid came from is where it will be traced back to if your disposal company fails.
Properly managing your CNC cooling fluids is essential to ensure optimal performance from your machines and tools. By following these five tips, you can rest assured that you are taking proper care of your CNC equipment for years to come!
