ABSTRACT:
An apparatus machines a workpiece by a rotating cutting tool having at least one coolant channel extended toward the free end thereof with high-pressure coolant jetting onto the free end of the cutting tool. The coolant has sufficient pressure and flow rate to remove the heat and the chips generated during the machining. The cutting tool is fed in a path suitable for each machining operation with the cutting edges being advanced into the workpiece in a reverse direction to the feed direction. The apparatus can machine a workpiece of a material having high hardness and high toughness.
