This low-viscosity, emulsion-type cutting fluid delivers strong processing performance comparable to standard emulsions. Moreover, it resists adhesion to chips and shavings, which helps prevent fluid loss during cutting. In addition, the formulation makes post-processing cleaning of machines and workpieces easier and more efficient. As a result, it offers excellent cost efficiency while maintaining clean operations. Furthermore, the micro-emulsion structure provides high oil–water separation properties, supporting stable and reliable cutting performance.
