Frequently Asked Questions
Q
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 rust protection suitable for most standard machining tasks.
Q
Is this cutting fluid safe for workers and the environment?
Yes. The fluid contains no harmful materials, is environmentally friendly, and is safe for workers. It is also odorless, making it comfortable for use in enclosed workshop environments.
Q
What is the pH value of the emulsion at 5% concentration?
The pH value of the emulsion at 5% concentration is 9.0, which falls within the mildly alkaline range. This helps provide effective rust inhibition and maintains stability during use.
Q
How does this fluid prevent metal burning during cutting?
The fluid features excellent wetting properties that allow it to penetrate the cutting zone efficiently, improving heat dissipation and cooling performance. This effectively prevents metal burning and thermal damage during high-speed or heavy-load operations.
Q
What dilution is recommended for heavy-load cutting applications?
For medium and heavy-load cutting, a higher concentration of 6–10% is recommended. The increased concentration provides greater lubrication and protection under demanding cutting conditions.
Q
What is the appearance of the concentrate and the working emulsion?
The concentrate appears as a light yellow transparent liquid with a density of 1.08 g/cm³ at 20℃. When diluted to working concentration, the emulsion becomes colorless and transparent, with a refraction factor of 2.5.
