Choose your metalworking fluid based on its performance, in your operations, given these basic criteria:

• Stability in solution
• Assist in your machining processes
• Produces good finishes
• Controls rust and corrosion
• Controls foams and mist
• Controls undesirable odors
• Controls undesirable residues
• Long fluid life given proper maintenance
• Safe to workers and to dispose of

No matter what the quality or cost is for the coolant you select, it will eventually fail in some respect. Failures can be chemical, biological, and even mechanical. They affect your machines, tools, parts, and your workers. However, sump life can be generously extended by performing preventative maintenance protocols.
