Properties of cutting fluid

 1.  High heat absorption for readily absorbing the heat developed

2.  Good lubricating qualities to produce low coefficient of friction
3.  High flash point so as to eliminate the hazard of fire
4.  Stability so as not to oxide in air
5.  Neutral so as not to react chemically
6.  Odorless so as not to produce any bad smell even when heated
7.  Harmless to the skin of the operator
8.  Harmless to the bearings
9.  Non corrosive to the work or machine
10.Transparency so that the cutting action of the tool may be observed
11. Low viscosity to permit free flow of liquid
12. Low priced to minimise production cost
