Frequently Asked Questions
What dilution ratio should I use for general machining operations?
For general machining, a 5% dilution is recommended. This concentration provides a balanced combination of lubrication, cooling, and corrosion protection suitable for most standard machining tasks.
Is this metalworking fluid compatible with aluminum alloys?
Yes. The fluid has been tested against both 7-series standard aluminum and magnesium-aluminum alloy, achieving Level 1 corrosion ratings on both — meaning no measurable corrosion occurs under standard test conditions.
What does the refractometer factor of 1.2 mean in practice?
The refractometer factor of 1.2 means you multiply your refractometer reading by 1.2 to get the actual concentration of the emulsion. This helps you accurately monitor and maintain the correct working concentration during use.
How does the fluid perform in areas with hard water?
The fluid offers good hard water resistance, which means it maintains stable emulsion quality and performance even when mixed with water that has a high mineral content. This reduces the risk of scum formation or emulsion breakdown.
What is the recommended concentration for heavy load cutting?
For heavy load cutting applications, a concentration of 10–20% is recommended. Higher concentrations provide enhanced lubrication and film strength needed to protect both the tool and workpiece under extreme cutting pressures.
Why is biological stability important in a metalworking fluid?
Good biological stability means the fluid resists bacterial and fungal growth during use and storage. This extends the service life of the fluid, reduces unpleasant odors, lowers maintenance costs, and helps maintain a safer working environment.
