Abstract (en)
[origin: WO9204151A1] A nozzle apparatus (10) adapted for use with machine tools of different configuration, which perform different machining operations, comprises a nozzle body (26) having a nozzle insert (42) mounted within an outlet passageway (36) formed in the nozzle body at its intersection with a coaxial, larger diameter inlet passageway (28) connected to a source (34) of coolant. The nozzle insert and outlet passageway are constructed to induce the formation of shock waves within the coolant stream in the course of its passage through the interior of the nozzle body which increase the energy and velocity of the coolant stream so that it is effective to pierce the heat barrier developed at the interface between the cutting insert (18) and workpiece (14), and to assist in the breakage of chips (87) from the workpiece.
