Go Beyond Production Challenges
Coolant foaming can be a frustrating and costly problem. The presence of excessive foam can be indicative of serious sump and machining problems. Foam obstructs the view of a workpiece, creates problems with the sump and filter media, harms surface finish quality, and impairs the performance of the metalworking fluid.
Protect your production from foaming problems
Is your concentration too high?
Coolant concentration is the first thing to check when excessive foaming occurs. A concentration that is too high will often cause foaming. Check the coolant concentration with a refractometer and adjust as necessary.
Is your water too soft?
The stability of foam can also be effected by water hardness. Soft water is more likely to cause foaming problems.
Are there mechanical problems causing foaming?
Mechanical problems in the system can create ideal conditions for foaming to occur. Check for leaking lines, cracks in hoses, or loose fittings. Repair or replace any hoses or pumps as needed.
Is your fluid level too low?
Fluid levels that are too low have been known to cause coolant foaming. If the fluid level is too low, there may be air being drawn into the pump causing foaming.
Is your pump pressure too high?
The velocity and pressure at which the coolant is being delivered can contribute to foam generation. High pressure and high velocity delivery will generate much more foam than a low pressure, high-volume delivery.
Are there contaminants or tramp oil present in your coolant?
The presence of tramp oil or other contaminants will also contributor to foam generation. Skim off the tramp oil and check for leaking oil lines or other sources of contamination
360° of fluid protection that stops problems before they occur.
Keep your production environment running smoothly.
Ashburn works with machine shops to determine the cause of problems such as foaming and makes recommendations that will protect their production, product quality, and metalworking fluid performance.
In partnership with Fluid Service Technologies, Ashburn offers unique, on-site service to protect your production from unnecessary delays and high-cost maintenance due to coolant contamination, chip interference, dirt and grime buildup, and biological contaminant hazards.
