A minimum quantity lubrication system for accurately measuring and controlling a volume and pressure of a lubricating fluid provided to a machining tool during minimum quantity lubrication machining operations. The minimum quantity lubrication system can further include measuring and controlling a volume and pressure of air provided during machining such that atomization of the lubricating fluid with the air can be controlled. Use of a continuous volumetric flow pump provides a continuous flow of lubricating fluid to the tool during machining operations.
