6 Signs You Need to Change Metal Working Fluids in CNC Machinery

Once you buy CNC machinery for sale, check the fluids on a regular basis. The frequency of fluid change normally depends on the manufacturing needs of a business. However, there are some signs that indicate using the machine with the same lubricants isn’t safe anymore. They can also become a hazard for your working environment.

This piece has shortlisted the indicators you need to keep an eye on for changing metal working fluids. Read on to know more about them.

Low Sump Value

Before starting every shift, make sure to check the sump level of the machine with a refractometer. If the sump level is below 30%, it indicates the loss of metalworking fluids. It also indicates the water evaporation that can lead to an increase in the concentration of chemicals in the fluid. Therefore, you should keep it in check daily.

Odd Looking Fluid

Whether you got a large or a small CNC machine for sale, check its fluid color on the regular basis. If the color turns grey or black, it usually is due to the presence of bacteria. However, if it has a brown or yellow color, it means the tramp oil is present in the fluid. This affects production efficiency and environmental safety.

Unwanted Materials on Surface

If the fluid has floating materials, chips, or some sort of mold growth, then it isn’t normal at all. Make sure you remove these substances with the help of a pump or a skimmer. You have to be consistent in keeping the oil skimmer and filtration system in top-notch condition to maintain the high-efficiency performance of the machine. However, if the production of these materials is consistent, then you can contact the experts at Flint Machine to help you out with fluid changing.

Foul Smell in CNC Machinery for Sale

If the machine fluid has a strong foul smell, change it without giving a second thought. Generally, this is due to the presence of micro bacterial growth that has now become uncontrollable. These organisms tend to be released into the air. Consequently, becoming the reason for severe health hazards.

Floating Tramp Oil on Top

If there is an excess of tramp oil, skim or pump it out from the surface. Some of the components in the fluids can cause irritation to the skin. Therefore, make sure to do it carefully, as these are not safe for your skin. The tramp oils contain high-level of metallic fines that when coming in contact with skin can cause irritation and dermatitis.

Dirty Trenches

If you are facing this problem, contact our CNC tool distributor in Georgia. It happens because emulsion has now become unstable, or the fluid cleaners have been reduced. Furthermore, it can also be due to the failure of the filtration system. Regardless of whatever the reason is, contact us to find the solution for it.

These are some of the signs that you should look out in CNC machine you got for sale. If any of these signs appear, contact Flint Machines. We’ll help you with changing the metalworking fluids to keep up the machine’s production efficiency.
