Abstract

The invention discloses a small-caliber non-spherical permanent magnet magnetorheological polishing processing machine tool, which belongs to the technical field of grinding-polishing processing, and is used for solving the problem that the shape and size accuracy requirements of a processed part cannot be met since each position of a small-caliber non-spherical curved surface to be processed cannot be contacted during processing of workpieces with the conventional polishing processing equipment. A workbench is arranged on an X axis linear unit of an XY precision movable platform; an organ protection cover is arranged between the edge of the workbench and a cover plate; a workpiece main shaft is arranged on the workbench through a workpiece main shaft bracket; a Z axis linear unit is arranged on a portal frame; a revolving table is arranged on the Z axis linear unit through a right-angle connecting frame; the shaft end of a rotating shaft in the revolving table is connected with a polishing head main shaft bracket through a two-dimensional precision fine adjustment displacement table; and the polishing head main shaft bracket has a certain inclination angle, so that an included angle between a polishing head main shaft on the polishing head main shaft bracket and a horizontal plane is 40-45 degrees. The machine tool is suitable for ultra-precision polishing processing of high-accuracy small-caliber non-spherical parts.

Description

technical field [0001] The invention relates to a polishing machine tool, which belongs to the technical field of lapping and polishing. Background technique [0002] With the increasing development of modern science and technology, various high-precision and high-surface-quality parts are required in the fields of national defense, aerospace, electronics, and biomedicine. The surface shape of these high-precision parts requires sub-micron shape accuracy, Nanoscale surface roughness and minimal subsurface damage. After direct forming or single-point diamond cutting and ultra-precision grinding, such parts need to be subjected to ultra-precision polishing on the surface to further improve their machining accuracy and parts performance. [0003] For the processing of some parts with relatively simple shapes and large scales, magnetorheological polishing is often used to achieve ultra-precision polishing. The principle of magnetorheological polishing is mainly to drive the mag...
