Abstract
A minimum quantity lubrication (MQL) system includes a controller, a lubricant module coupled to a tool spindle of a machining apparatus, and a pneumatic module coupled to the spindle. The lubricant module is configured to supply lubricant at pressure to the tool, as controlled by the controller. Likewise, the pneumatic module is configured to supply pressurized air to the tool, as controlled by the controller. The controller is configured to direct the lubricant module to supply lubricant prior to the controller receiving a START signal from a machine tool controller. Optionally, the lubricant pressure level is predetermined based on known characteristics of the tool that is coupled to the spindle. Optionally, the START signal is anticipated by referring to a signature/profile of the operational steps of a machining process where a timeline or time table of lubrication request intervals are identified.
