The, perhaps safety concern , and this is the reason I was given over 50
years ago is that a chuck must 'lock-up' when holding a work piece.
However if it is lubricated and given there is vibration, heat and a

during a machining operation is far greater if lubrication is involved.ere

Dunno about lubing chucks but I learned from experience NOT to use any lube on the curved dovetail ways of a tilting vise. It matters not how tight the clamp is cranked down it will slip if there's lube on the ways and clamp.
