Mastication is mechanical process of chewing with lubrication and digestion process by saliva.
No lubrication is necessary under normal use.
In a mechanical system such as surface to surface movements or a mechanical seal normal lubrication does nor penetrate in the gaps where lubrication is essential due to force / pressure in the mating part or seal. Lubrication in this case is forced into the joints by applying pressure resulting in forced penetration of lubricant.
Yes sufficient lubrication is always necessary

As a "train", there is no typical lubrication system, as it is not necessary. Individual components have grease systems and locomotive components include multiple lubrication systems. So, there is no single invention of a train lubrication system.

NAICS 333613 applies to Mechanical Power Transmission Equipment Manufacturing.
It would depend on the environment in which the equipment is being used
Short-, intermediate-, and long-term support requires bedside monitoring of the equipment and patient throughout treatment.
Lubrication can be used for bearings on vehicles and farm equipment to make sure that it runs smoothly and diminishes friction. Lubrication can also be used for personal use when having intimate relations with a person to increase comfort or arousal.
Before oil there was not need for lubrication as there were no engines or other mechanical devices to lubricate.
