Coolants (Cutting fluids):
- Coolants (Cutting fluids) play an important role in reducing the wear of cutting tools.
- The basic function of coolant in machining is to cool the work material (job) and tool.
- Coolants (Cutting fluids) are essential in most metal-cutting operations.
- During a machining process, considerable heat and friction are created by the plastic deformation of metal occurring in the shear zone when the chip slides along the chip tool interface.
- This heat and friction cause the metal to adhere to the cutting edge of the tool, and the tool may break down.
- The result is poor finish and inaccurate work.
