What is recommended for lubricating the ways of a lathe or the gibs of a mill?

Using a central lubricating system's fluid is recommended for lubricating the ways of a lathe or the gibs of a mill due to several reasons related to machine performance and longevity. The central lubrication system is designed to provide a consistent and adequate supply of lubricant to critical moving parts of the machining equipment. This helps in reducing wear, minimizing friction, and maintaining smooth operation during machining processes.

Central lubricants are often formulated to have specific properties that are ideal for the types of materials used in machine ways and gibs, ensuring proper adhesion and preventing the formation of deposits that can occur with other types of lubricants. Furthermore, they are less prone to evaporation or degradation over time compared to other lubricants, providing ongoing protection and enhancing the lifespan of the machine components.

In contrast, other options do not provide the same level of performance. Engine oil, while a good lubricant for certain applications, may not have the necessary additives or viscosity suitable for lathe ways and mill gibs. Cutting oil is primarily designed for use during machining operations to cool and lubricate the cutting tool, not for the machine's moving parts. Water-based lubricants, while environmentally friendly, might not offer the necessary protection against wear and corrosion that machines require, particularly in the high
