Troubleshooting Metalworking Fluids

LEGEND OF CAUSES
Concentration Low or High			Poor Tramp Oil Removal			High Pressure or Temperature
Water Hardness Low or High			Poor Chip Filtration
pH Low			Over-Aeration

SUMP OR TANK CONDITIONS
Grease Formations Add softener agent, or consider RO water Filter metals down to 10µ	Foam Add hardener agent Decrease aeration Decrease pressure
Gummy Residues Decrease concentration Add softener agent, or consider RO water	Split Emulsion Add softener agent, or consider RO water Filter metals down to 10µ
Emulsified Oils Remove tramp oils Filter metals down to 10µ
HEALTH & SAFETY
Odor See "Bacterial Contamination" below	Skin Sensitivity Decrease concentration See "Bacterial Contamination" below Remove tramp oils
Excessive Mist Remove tramp oils
PARTS & TOOLS
Rust/Corrosion Add softener agent, or consider RO water See "Bacterial Contamination" below	Tool Breakage Increase concentration
Poor Finishes Increase concentration Filter metals down to 10µ
