• Are coolant and lubricant same?

1. Yes
2. No

Ans: (2)

• All coolants are a cutting fluid. State True or False.

1. True
2. False

Ans: (1)

Cutting fluid serves two purposes- one is cooling and another is lubricating. When the cutting fluid is used to take away the heat generated in the workzone during the machining operation, it is termed as coolant. When the cutting fluid is used to reduce the co efficient of friction between the cutter surface and chip, it is termed as lubricant.

• Which one is true?

1. Water is a good coolant
2. Water is a good lubricant
3. Water is not used as cutting fluid
4.  Both (1) and (3)

Ans: (4)

• Water is not used as cutting fluid because:

1. It posseses high lubricity
2. It is highly corrosive
3. It can’t reduce temperature
4. It can’t reduce the friction

Ans: (2)
