Abstract
A coolant supply system for a machine tool comprises a coolant source; a nozzle for directing coolant to inside of a workpiece from the coolant source; another nozzle for directing coolant to outside of the workpiece from the coolant source; and a valve for automatically selectively directing coolant only to the inside of the workpiece, thereby increasing coolant flow to the inside of the workpiece when needed.
