Embodiment Construction

[0013] figure 1 An exemplary embodiment of the invention is shown. The automatic polishing apparatus in this embodiment comprises a circular container 11 containing an abrasive slurry 12 comprising a plurality of abrasive grains and a carrier liquid driven by a liquid pump 13, wherein the liquid pump 13 drives the abrasive slurry in the circular container. Abrasive slurry fluid 12 is formed in 11 . The workpiece 15 to be polished is mounted on a three-axis rotating platform 16 immersed in the abrasive slurry fluid 12 . By changing the orientation of the workpiece 15 in a controllable manner through the three-axis rotating platform 16, the three-axis rotating platform 16 can be automatically adjusted to achieve a gentle and uniform surface treatment of the workpiece 15. In one example, the workpiece 15 is an aluminum product with a complex curved surface profile, and its size is less than 50 (length) x 50 (width) x 50 (height) mm 3 . The workpiece 15 is dipped into an abras...

Abstract

The present invention discloses an automatic polishing device and the method of using the device for the surface finishing of a workpiece such as complex-curved-profile parts. Automatic polishing is performed by mounting the workpiece on an apparatus which enables different orientations along multiple axes and immerging the workpiece in a controlled flow of abrasive slurry. The device of the present invention provides a uniform finish on free form surface. It is also precise, low cost, non-destructive, and non-polluting.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 61 / 686,852, filed April 13, 2012, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to automated polishing equipment and, in particular, to fluid-based polishing equipment for surface polishing of complex curved contour parts. Background technique [0004] Polishing is an important process that utilizes mechanical or chemical reactions to form a smooth and shiny surface and has been used by the manufacturing industry for hundreds of years. Processes using automated polishing machines, such as those used to polish semiconductor wafers and polish precision optical components, are more efficient than manual polishing. However, the use of such automatic polishers is limited to parts with regular surface contours. Since in many cases the surface profile of the part being polished...
