Abstract
A fluidostatic tool with at least one rolling element uses a pressurized lubricant mist or aerosol to apply force against a metal workpiece surface that is flat, curved or cylindrical. The rolling element, such as a ball, is held within a tubular borehole of the tool and cushioned on the pressurized lubricant mist during machining of the metal surface. Viscosity of the lubricant mist increases and reduces friction between the ball and the metal surface as it exits the tool, thereby reducing or eliminating the need for other lubricants during the machining process. The pressure of the lubricant mist against the ball seals the borehole of the tool and prevents leakage of the pressurized lubricant mist when the tool is not engaged with a metal workpiece surface. The lubricant mist can be an oil-free lubricant or a mixture of oil-free lubricant and oil components.
