Troubleshooting the Flood Coolant System on Your Cold Saw Troubleshooting the Flood Coolant System on Your Cold Saw

The flood coolant system is arguably the most important part of a cold saw. When issues with your cold saw arise, troubleshooting the flood coolant system on your cold saw is the first step you should take. Issues such as crooked cutting, chips welding to the teeth of the blade, teeth breaking, and rapid tooth wear are all common problems on a cold saw that can be caused by issues with the flood coolant system. This article will outline how to make sure you flood coolant system is working properly and how to correct any issues.

Will This Work for Your Saw?

There is no one size fits all solution for flood coolant system issues, because each type of saw is different, and each one may consist of different components. This guide will help go over the basic issues to try and determine why your coolant system is not working. Your cold saw may or may not have all of the components mentioned, but troubleshooting the components your saw does have will still help provide a solution.

Clean the System and Check Coolant Flow

If you are having issues with your blade cutting straight, or teeth breaking you need to check that your flood coolant system is flowing properly. First off, since some saws have a shutoff switch for the coolant, make sure that you have not accidentally turned the switch off. If you have verified that your switch is on, then since you should already be regularly cleaning the coolant system, make sure it has been recently cleaned. If you have not cleaned it in a while that is most likely your issue. Make sure that you not only clean the tank, but also the hoses and valves that distribute the fluid.

Fluid Concentration

If everything is clean and you are still having issues, you need to make sure you are using the correct fluid concentration. The coolant on your saw is not a place to cut corners, you should avoid any thinly mixed soluble oils and purchase the highest quality lubricant that you can afford. Some of the new synthetic oils work very well. Since each lubricants concentration varies, you need to make sure that you are following the directions on the bottle of coolant exactly.

Flow Output

Another solution is to make sure that you have the flow of the coolant system set high enough for the material you are working with. Don't try to skimp on how much fluid you are using, an increase in fluid flow can only help with lubrication, especially during higher velocity cuts. The fluid will help reduce friction and take the heat away from your work zone, thereby protecting the life of your tools and making sure you produce a consistent product.

Nozzle Placement

Now this may not be a possibility in all saws, but you do need to make sure that your nozzle is depositing the fluid where it is needed most. The most critical zones of cutting are the tool tip, the tool flank, and as a barrier between the chip and the tool face. You need to make sure that each one of these areas is getting the proper amount of fluid, this may require a special nozzle design or placement. Nozzles that generate a smooth laminar flow of fluid are more efficient and work best.

Check the Pump

Lastly, you should make sure that your flood coolant pump is working properly. If you are not getting any sort of fluid delivery up through the hoses and nozzle and you have verified that everything is clean and the right concentration is being used, you may want to assume that the coolant pump is the issue. Depending on the model of your saw, replacement pumps can be purchased separately from the entire coolant system. Check with your manufacturer for details.
