Cutting oil and Coolant

What is Cutting oil and Coolant for Sharpening?


   
Cutting oil is a type of coolant and lubricant designed specifically for metalworking processes, such as machining and stamping. There are various kinds of cutting fluids, which include oils, oil-water emulsions, pastes, gels, aerosols (mists), and air or other gases. They may be made from petroleum distillates, animal fats, plant oils, water and air, or other raw ingredients.



Functions of Cutting oil.


1. Cooling.
    Metal cutting generates heat due to friction and energy lost deforming the material. The surrounding air has low thermal conductivity (conducts heat poorly) meaning it is a poor
coolant. Ambient air cooling is sometimes adequate for light cuts and low duty cycles typical of maintenance, repair and operations (MRO) or hobbyist work.

    Production work requires heavy cutting over long time periods and typically produces more heat than air cooling can remove. Rather than pausing production while the tool cools, using liquid coolant removes significantly more heat more rapidly, and can also speed cutting and reduce friction and tool wear.



2. Lubrication.

    Cutting oil aid the cutting process by lubricating the interface between the tool's cutting edge and the chip.

By preventing friction at this interface, some of the heat generation is prevented. This lubrication also helps prevent the chip from being welded onto the tool, which interferes with subsequent cutting.

    Extreme pressure additives are often added to cutting fluids to further reduce tool wear.



How to choose cutting oil?


    In order to select the only cutting oil for you, you need to gather some basic information relevant to the selection criteria.

    For purposes of simplicity, you need to know the metals in use, the predominant machining operations, basic machine types, tooling specifics, plant processes and chemical restrictions for your facility.
