High Pressure Lubricooling Machining Of Metals, Marian Mazurkiewicz

Mining Engineering Faculty Research & Creative Works

A method of machining metals, by effecting relative movement between a work piece and a tool having a cutting edge to cut the work piece and produce a chip, including injecting a high pressure jet of cooling liquid into the cutting zone during machining, the jet being at a pressure of at least about 5,000 p.s.i. The jet is preferably injected between the chip and the rake face of the cutting tool, and the trajectory of the jet is offset from the rake face of the cutting tool by a small amount and the jet is aimed at the cutting …
