Frequently Asked Questions
Q
What concentration should I use for general machining?
For general machining applications, a dilution of 5% is recommended. This provides a balanced level of lubrication, cooling, and corrosion protection suitable for most standard operations.
Q
Can this coolant be used in areas with hard water supply?
Yes. This coolant is specifically formulated to perform reliably in high hardness water environments, maintaining stable emulsion quality and effectiveness even with elevated mineral content in the water.
Q
How does this coolant help extend service life?
The coolant's inherent cleanliness property and preservation ability work together to resist bacterial growth and contamination, significantly extending the usable service life of the fluid compared to conventional alternatives.
Q
Is this coolant safe to use with magnetic chucks that have brass serrations?
Yes. This coolant is formulated to be non-aggressive toward brass serrations on magnetic chucks, preventing corrosion or chemical damage to these sensitive components during grinding and machining operations.
Q
What is the recommended dilution for heavy-load cutting operations?
For medium and heavy-load cutting operations, a concentration of 6–10% is recommended. A higher concentration provides enhanced lubrication and thermal protection required under more demanding machining conditions.
Q
What is the pH value of the emulsion and why does it matter?
The emulsion has a pH value of 9.0 at 5% concentration. This mildly alkaline pH level is important for effective rust inhibition, microbial control, and compatibility with most metals used in machining, while also being safe for operator handling.
