Maxtop Cutting oil (MTCO) is formulated by hydrogenating and solvent refining base oil, and blending it with special additives such as extreme pressure anti-wear, antioxidant and anti-rust agents. Rapidly reduce the temperature in the cutting area to prevent workpiece deformation and tool wear. Form a stable lubricating film under extreme pressure to extend the tool life. Inhibit the oxidation reaction during the processing and protect the surface of the machine tool and the workpiece. Effectively suspend metal debris, keep the processing environment clean, and reduce downtime for maintenance. The low-volatility formula reduces the spread of oil mist, meeting environmental protection and occupational health requirements.
