Solution:

Properties of cutting fluid: (Any four 1⁄2 mark each)

1. High heat absorption

2. Good lubricating qualities to produce low coefficient of friction

3. Low viscosity to permit free flow of liquid

4. Non-corrosive to the work or the machine

5. High flash point so as the eliminate the hazards of fire

6. Odourless, so as not to produce any bad smell

7. Harmless to the skin of operator
