Correct option is D
Soluble oil is the most commonly used cutting fluid in almost all machining operations because it:
·
Forms an emulsion with water – Provides both
cooling and
lubrication during machining.
·
Dissipates heat effectively – Reduces tool wear and improves cutting efficiency.
·
Reduces friction – Enhances tool life and improves surface finish.
·
Prevents corrosion – Contains additives to protect machine parts and workpieces.
·
Cost-effective and versatile – Used in
turning, milling, drilling, grinding, etc.
