Cutting Fluid Formulated with specially selected high-performance extreme pressure additives, rust inhibitors, and other additives, this product is a new generation of high-performance, multi-purpose cutting/grinding fluid. It offers excellent extreme pressure lubrication, rust prevention, cooling, and cleaning properties. It exhibits strong resistance to microbial degradation and maintains stability under varying water hardness conditions. It also demonstrates excellent oil resistance against contamination from guideway oils in CNC machining centers and numerical control centers. Product Advantages: * Contains special extreme pressure lubricating additives, significantly reducing tool wear. * Uses high-molecular water/oil-soluble rust inhibitors, providing excellent rust protection for equipment and workpieces. * Low foaming tendency and good cleaning performance, replacing traditional emulsified oils (also known as saponified oils). * High transparency, facilitating monitoring of workpiece surface processing conditions. * Long service life with a replacement cycle of over one year, meeting environmental requirements, reducing waste, and improving production efficiency. * Harmless to operators’ skin and non-damaging to machine paint, with protective effects.
