This solution-type cutting fluid delivers processing performance equal to emulsion-type oils while maintaining a cleaner operating profile. Moreover, its excellent antibacterial properties reduce the need for frequent eco-exchanging, which lowers maintenance effort. In addition, it removes chips efficiently during cutting, helping keep machines clean and improving overall operation efficiency. Furthermore, the formula contains no chlorine-based extreme pressure additives. As a result, it eliminates concerns about the possible generation of highly toxic dioxins while supporting safe and reliable machining.
