Question

Soap solutions are used in high speed cutting and grinding because
A) It acts as a lubricant
B) It absorbs heat produced during cutting or grinding
C) It increases friction to facilitate cutting
D) Both A and B are correct a A​

Answer 1

Soap solutions are used in high speed cutting and grinding because:

• It acts as Lubricant
• It absorbs heat during cutting and grinding.

So, C) option is correct !

• Soap solutions act as lubricant by reducing the friction between the contact parts of the machineries. Also, their action is very similar to oil as they fill up the small undulations in the contact surfaces and reduce friction.

• Similarly, they can absorb the heat released due to friction between machine parts , thereby keeping the contact surfaces cool and also prevents wear-tear.
