Abstract

The present application discloses a nanofluid micro-lubrication and atomization cooling ultra-precision cutting medium supply system, comprising: a workbench, a compressed air path, a nanofluid liquid path, a tool, a workpiece to be processed, and a jet atomization nozzle; The workpiece to be processed is set on the worktable, and moves toward or away from each other; the jet atomization nozzle is arranged on one side of the tool, and the second end of the jet atomization nozzle is arranged towards the cutting area where the tool contacts the workpiece to be processed; the jet atomization nozzle The second end of the jet sprays a three-phase bubble-like flow to the cutting area at a near-sonic speed. By setting the jet atomization nozzle, the high-speed atomization of the nano-fluid can be realized by using compressed air, so that a large number of tiny droplets are formed after spraying, which are evenly attached to the cutting surface of the cutting area, thereby effectively solving the problem of direct nano-fluid directly. Technical problems when used for cutting.

Description

technical field [0001] The application relates to the technical field of ultra-precision cutting, in particular to a nano-fluid micro-lubrication and atomization cooling ultra-precision cutting medium supply system. Background technique [0002] Because the cutting objects are mostly difficult-to-machine materials, such as anisotropic composite materials, infrared optical hard and brittle materials, etc., a large amount of heat will be generated during the cutting process. Since the material layer to be cut is relatively thin, most of the heat is transmitted. When entering the workpiece, only a small part of the heat is taken away by the chips. The heat introduced into the workpiece will adversely affect the ultra-precision cutting process, resulting in pitting, pits, cracks, and surface / subsurface damage on the machined surface. Defects, reducing the service life and working reliability of the parts, but also aggravating the wear of the tool and affecting the service life o...
