What is cutting oil and what role does it play in metalworking processes?

Cutting oil is a type of lubricant specifically formulated for use in metalworking operations such as cutting, drilling, milling, and turning. It serves several critical functions:

Lubrication: Reduces friction between the cutting tool and the workpiece, minimizing tool wear and energy consumption.
Cooling: Dissipates heat generated during machining, preventing thermal damage to both the tool and the workpiece.
Chip Removal: Assists in flushing away metal chips and debris from the cutting area, maintaining a clear workspace and preventing re-cutting of chips.
Surface Finish Improvement: Enhances the quality of the machined surface by reducing friction and preventing metal adhesion.
By performing these roles, cutting oil improves machining efficiency, prolongs tool life, and ensures better product quality.
