Claim:
An apparatus comprising: a first holder for retaining a workpiece; a second holder for retaining a tool configured to remove material from said workpiece; each of said first and second holders comprising one of a first chuck, a second chuck, and a spindle; a turret supported independently of the first and second holders and supported for rotation about a turret axis, the turret having plural facets; at least one rotary holder rotatably coupled to a selected one of the facets of said turret and configured to rotate about a nozzle axis that is different from the turret axis; a coolant nozzle having a nozzle body shape that is one of angled and curved with respect to the nozzle axis, the coolant nozzle being coupled to the rotary holder and fluidly communicating with a source of pressurized coolant, the coolant nozzle further including a tip portion having a discharge outlet for discharging coolant, said discharge outlet being spaced from the nozzle axis; a motor operatively coupled to said rotary holder and configured to rotate said rotary holder about the nozzle axis and relative to said turret; a computer control system operatively coupled to said first and second holders, to said motor, and to said turret, said computer control system including a computer readable medium having disposed thereon executable code which, when executed, is configured to: cause relative movement of said first holder and said second holder; rotate said turret about the turret axis to a coolant operative position; operate the motor to rotate the rotary holder about the nozzle axis, which is different from the turret axis, so that the discharge outlet of the coolant nozzle is indexed to a predetermined position; and selectively introduce coolant through said coolant nozzle.
