What is the importance of maintaining proper lubrication in machining?

Maintaining proper lubrication in machining is crucial primarily because it significantly reduces friction, wear, and overheating of cutting tools. When lubrication is applied, it creates a barrier between the tool and the workpiece, allowing them to move more smoothly against each other. This reduction in friction helps prevent excessive heat generation during the cutting process, which can lead to tool degradation and premature failure. Additionally, effective lubrication aids in the removal of chips away from the cutting zone, further lowering the chances of overheating and ensuring that the cutting tools maintain their effectiveness and longevity. Proper lubrication ultimately contributes to higher precision in machining operations and improved surface finishes on the workpiece, which is essential for quality manufacturing.
