Question

Consider the following statements regarding desirable properties of cutting fluid

1. It should get oxidised when left in air.

2. It should react with the materials of machine tool parts.

3. It should wet the surface of cutting tool and workpiece.

Which of the above statements is/are correct ?  

1. 2 only
2. 3 only
3. 2 and 3 only
4. 1, 2 and 3
5.

Answer 1

Correct Answer - Option 2 : 3 only

Explanation:

Cutting fluids are used for decreasing power requirement and increasing heat dissipation.

The desirable properties of cutting fluid are:

• It should not get oxidised when left in air
• It should not react with the material of machine tools parts
• Easily available
• It should not foam
• Low viscosity
• It should wet the surface of cutting tool and workpiece for better heat dissipation.
