Abstract

The invention discloses a nanofluid minimal quantity lubrication and atomization cooling ultra-precision cutting medium supply system. The system comprises a workbench, a compressed air path, a nanofluid liquid path, a cutter, a workpiece to be machined and a jet flow atomization nozzle; the cutter and the workpiece to be machined are arranged on the workbench and move in the same direction or away from each other; the jet flow atomization nozzle is arranged on one side of the cutter, and the second end of the jet flow atomization nozzle faces a cutting area, making contact with the workpiece to be machined, of the cutter; and the second end of the jet flow atomization nozzle sprays three-phase bubble flow to the cutting area at the near sound speed. By arranging the jet flow atomization nozzle, high-speed atomization of the nanofluid can be achieved through compressed air, a large number of tiny liquid drops are formed after the nanofluid is sprayed out, the tiny liquid drops are evenly attached to the cutting face of the cutting area, and therefore the technical problem existing when the existing nanofluid is directly used for cutting is effectively solved.

Description

technical field [0001] The application relates to the technical field of ultra-precision cutting, in particular to a supply system of ultra-precision cutting medium for nano-fluid micro-lubrication and atomization cooling. Background technique [0002] In ultra-precision cutting, most of the cutting objects are difficult-to-machine materials such as anisotropic composite materials, infrared optical hard and brittle materials, etc. During cutting, a large amount of heat will be generated. Since the material layer to be cut is relatively thin, most of the heat is transmitted Into the workpiece, only a small part of the heat is taken away by the chips, and the heat introduced into the workpiece will have an adverse effect on the ultra-precision cutting process, resulting in pitting, pits, cracks and surface / subsurface damage on the machined surface. Defects reduce the service life and reliability of the parts, and at the same time increase the wear of the tool and affect the se...
