Coolant spray nozzle and cutter with coolant spray nozzle

A coolant spray nozzle for use in conjunction with a milling cutter containing a coolant duct wherein the milling cutter retains a milling insert with a cutting edge engaging a workpiece at an insert-chip interface having a length, and the coolant spray nozzle comprising:

• a coolant spray nozzle body containing a bore and an adjustable fan spray nipple having a slot with a slot opening through which coolant discharges in a fan-shaped coolant spray so as to impinge the insert-chip interface along substantially the entire length of the insert-chip interface;
• the adjustable fan spray nipple comprising a generally spherical nipple body;
• the coolant spray nozzle body including a generally spherical chamber which accommodates the generally spherical nipple body of the adjustable fan spray nipple;
• wherein the adjustable fan spray nipple is rotatably adjustable, along different planes of rotation, with respect to the coolant spray nozzle body;
• the coolant spray nozzle body having an enlarged nozzle head region
• the generally spherical nipple body of the adjustable fan spray nipple is accommodated in the generally spherical chamber via an interference fit;
• and
• the interference fit retains the adjustable fan spray nipple in position during coolant discharge;
• the adjustable fan spray nipple being adjustable 360 degrees, with respect to each of three planes of rotation that are orthogonal with respect to one another, to a selected position relative to the coolant spray nozzle body.

A milling cutter assembly comprising:

• a milling cutter body containing a coolant duct, and the milling cutter body retaining a milling insert with a cutting edge wherein the cutting edge engaging a workpiece at an insert-chip interface having a length;
• a coolant spray nozzle comprising:
• a coolant spray nozzle body containing a bore and an adjustable fan spray nipple having a slot with a slot opening through which coolant discharges in a fan-shaped coolant spray so as to impinge the insert-chip interface along substantially the entire length of the insert-chip interface;
• the adjustable fan spray nipple comprising a generally spherical nipple body;
• the coolant spray nozzle body including a generally spherical chamber which accommodates the generally spherical nipple body of the adjustable fan spray nipple;
• wherein the adjustable fan spray nipple is rotatably adjustable, along different planes of rotation, with respect to the coolant spray nozzle body.
