Frequently Asked Questions
Q What dilution ratio should I use for general machining operations?
For general machining operations, a dilution ratio of 5% is recommended. This concentration provides a balanced combination of lubrication, cooling, and corrosion protection for most standard machining tasks.
Q Is this metalworking fluid compatible with aluminum alloys and magnesium-aluminum alloys?
Yes. The fluid has been tested and achieves Level 1 corrosion protection on both 7-series standard aluminum and magnesium-aluminum alloys, making it suitable for machining a wide range of non-ferrous metals.
Q What is the recommended pH value when the fluid is used at 5% concentration?
When diluted to a 5% working emulsion, the pH value should be maintained at 8.8 ± 0.5. Monitoring the pH regularly helps ensure optimal corrosion protection and biological stability during use.
Q How does the fluid perform in areas with hard water?
This fluid offers good hard water resistance, meaning it maintains stable emulsion quality and performance even when mixed with water that has a high mineral content, reducing the risk of emulsion breakdown or residue buildup.
Q What is the refractometer factor and why does it matter?
The refractometer factor for this fluid is 1.2. This value is used to accurately calculate the actual concentration of the working emulsion using a refractometer. Multiply the refractometer reading by 1.2 to get the true concentration percentage.
Q What concentration is suitable for heavy load cutting applications?
For heavy load cutting applications, a higher concentration of 10–20% is recommended. This ensures maximum lubrication and protection under extreme cutting pressures, reducing tool wear and improving surface finish quality.
