Cutting Fluids

Any liquid or a gas utilized to cool as well as to lubricate is known as a cutting fluid. Its functions are either to cool or lubricate or both cool & lubricate the tool.

To provide satisfactory service, the cutting fluid must possess

a.    good lubricating property,
b.    low viscosity so that lubricant might easily fill in the cracks formed on the workpiece.
c.    chemical stability,
d.    non-corrosive nature towards the metals of the workpiece in addition to tool, and
e.    high thermal conductivity.
