1. cutting fluid: it is an industrial liquid used to cool and lubricate tools and workpieces during metal cutting and grinding.
2. Cutting oil: A certain proportion of animal and vegetable oil (5% ~ 10%) is added to mineral oil, which is a composite oil and is suitable for light load cutting.
Second, the characteristics are different.
1. Cutting fluid: It has good cooling performance, lubricating performance, antirust performance, degreasing and cleaning function, anticorrosion function and easy dilution.
2. Cutting oil: it has super extreme pressure effect of lubrication, effectively protects the tool, prolongs its service life, and can obtain extremely high workpiece precision and surface smoothness.
Third, the combination is different.
Cutting fluid: water-based cutting fluid can be divided into emulsified cutting fluid, semi-synthetic cutting fluid and fully synthetic cutting fluid. Each cutting fluid will contain various additives except base oil: rust inhibitor, non-ferrous metal corrosion passivator, defoamer and so on.
2. Cutting oil: The refined base oil is synthesized by compounding additives such as sulfurized lard, sulfurized fatty acid ester, extreme pressure antiwear agent, lubricant, antirust agent, mildew-proof bactericide, antioxidant and coolant in different proportions.
Four, the application of cutting fluid and cutting oil:
1. Cutting fluid: The lubrication function of metal cutting fluid (cutting fluid for short) in cutting process can reduce the friction between rake face and chip, and between flank face and machined surface, and form a local lubrication film, thus reducing cutting force, friction force and power consumption; In the process of metal cutting, cutting fluid is required to have good cleaning effect.
2. Cutting oil: suitable for cutting, high-speed cutting and heavy-load cutting of metal products such as cast iron, alloy steel, carbon steel, stainless steel, high-nickel steel, heat-resistant steel and die steel. Including turning, milling, boring, high-speed tapping, drilling, reaming, broaching, hobbing and other cutting processes.
