Abstract
A minimum quantity lubrication (MQL) tool including a lance. The lance includes a passageway and an orifice. The passageway extends axially from a first end of the lance toward a second end of the lance and allows a lubricant supply to flow therein from the first end of the lance toward the second end of the lance. The first orifice extends radially through the lance at a location near the second end of the lance. The lubricant supply flowing through the passageway exits the orifice and is impinged upon by air flowing around the lance.
Claims20
A minimum quantity lubrication (MQL) tool comprising:
- a lance rotatable about a longitudinal axis, the lance including:
- a passageway extending axially from a first end of the lance toward a second end of the lance and allowing a lubricant supply to flow therein from the first end of the lance toward the second end of the lance;
- and
- a first orifice extending radially through the lance at a location near the second end of the lance,
- wherein the lubricant supply flowing through the passageway exits the first orifice and is impinged upon by air flowing around the lance to form an air-oil mist at a location upstream of the second end of the lance.
A minimum quantity lubrication (MQL) tool comprising:
- a lance rotatable about a longitudinal axis, the lance including:
- a passageway extending axially from a first end of the lance toward a second end of the lance and allowing a lubricant supply to flow therein from the first end of the lance toward the second end of the lance;
- and
- a plurality of apertures extending radially from an inner cylindrical surface of the lance to an outer cylindrical surface of the lance,
- wherein the lubricant supply flowing through the passageway exits the plurality of apertures and is impinged upon by air flowing around the lance to form an air-oil mist at a location upstream of the second end of the lance.
A minimum quantity lubrication (MQL) tool comprising:
- a cutting tool configured to remove material from a workpiece;
- a coupling extending at least partially into the cutting tool and configured to provide air-oil mist flowing therethrough to the cutting tool;
- and
- a lance rotatable about a longitudinal axis, the lance including a first end and an opposing second end that extends at least partially into the coupling, the lance further includes:
- a passageway extending axially from the first end of the lance toward the second end of the lance and allowing a lubricant supply to flow therein;
- a first orifice extending radially from an inner cylindrical surface of the lance to an outer cylindrical surface of the lance;
- and
- a second orifice extending radially from the inner cylindrical surface of the lance to the outer cylindrical surface of the lance, the second orifice diametrically opposed to the first orifice,
- wherein the lubricant supply flowing through the passageway exits the first and second orifices and is impinged upon by air flowing around the lance to form air-oil mist at a location upstream of the second end of the lance,
- wherein the first and second orifices are located between 1-2 millimeters away from the second end of the lance and have a diameter that is less than 1 millimeter.
