Abstract

The invention discloses a three-phase flowing pressure cavitation polishing method. Free curved surface workpieces are fixed at the bottom of a polishing liquid container through a fixture; a cylindrical polishing tool is not directly contacted with the free curved surface workpieces, and is dipped in polishing liquid; a series and parallel connection polishing platform controls poses of a polishing tool relative to the workpieces, so that a tiny machining gap is always kept between the tool and the surfaces of the workpieces; a servo motor drives the cylindrical polishing tool to rotate at high speed above the workpieces through a connecting device, so that polishing liquid mixed with abrasive particles is rotated under the effect of high-speed rotation of the tool; the polishing liquid passes through the wedge gap between the tool and the workpieces to generate extrusion to increase the pressure and to generate dynamic pressure; and the abrasive particles are pressed in the surfacesof the workpieces to generate surface and subsurface damage so as to realize more precise polishing of the surfaces of the workpieces. The method improves the polishing efficiency under the precondition of not generating the surface and subsurface damage.

Description

technical field [0001] The invention relates to the technical field of ultra-precision machining, and more specifically relates to a three-phase flow pressure cavitation polishing method and device. Background technique [0002] With the development of science and technology, ultra-precision machining technology is not only an important development direction of modern manufacturing science and technology, but also an important basis for future advanced manufacturing technology. The rise of ultra-precision machining has significantly improved the surface roughness of most current workpieces, and at the same time, the performance and reliability of products have also been improved. The ensuing problem is that the precision requirements of parts in different fields are increasing day by day. In order to obtain higher processing accuracy and surface quality, it is necessary to realize ultra-smooth surface processing on the surface of precision optical parts and functional cryst...
