ABSTRACT:
A method is disclosed for applying an ordinarily high viscosity lubricant as an atomized spray onto metal working surfaces without the use of high velocity air. The method comprises the steps of heating the lubricant to a temperature of approximately 170.degree. to 300.degree. F., hydraulically atomizing the lubricant by feeding the lubricant through a nozzle under a pressure of approximately 30 to 70 pounds per square inch whereby the relative velocity of the lubricant with respect to ambient atmosphere is increased upon exiting an orifice in the nozzle, and directing the lubricant onto the metal working surfaces.
