Suspension base disc polishing device capable of being actively driven

Abstract

The invention discloses a suspension base disc polishing device capable of being actively driven. The suspension base disc polishing device comprises an actively driven grinding transmission device, a suspension base disc, a correction ring and a grinding disc; the actively driven grinding transmission device is fixedly connected with the correction ring, and drives the correction ring to rotate; the correction ring is fixedly arranged on the grinding disc through a fixing piece and can rotate around a fixing center line; the suspension base disc is clamped in the correction ring; the suspension base disc polishing device is characterized in that a plurality of wedged grooves are arranged on the suspension base disc along the circumference direction; the wedged grooves are full of polishing liquid; the correction rings drive the suspension base disc to do gyration movement; the suspension base disc generates liquid dynamic pressure under the gyration movement, so that a work piece floats; and the work piece is in contact with a grinding material of the polishing liquid. The suspension base disc polishing device provided by the invention has the advantages of simple structure and relatively low cost; the surface roughness and the flatness of the work piece can be improved; the internal damage of the work piece, caused by polishing, can be reduced due to flexible contact between the work piece and each polishing particle; and the simple operation conditions are simple and the development prospect is wide.

Description

technical field [0001] The invention relates to a suspension substrate polishing device which can be actively driven. Background technique [0002] Grinding is to inject abrasives of different specifications on rigid grinding tools (such as cast iron, tin, aluminum and other soft metals or hard wood, plastics, etc.), and under a certain pressure, through the relative sliding of the grinding tool and the workpiece, the abrasive grains are removed by cutting Processing of surface trace materials. [0003] The original plane grinding equipment is an online correction processing method, which mainly relies on the friction between the inner and outer sides of the workpiece polishing disc on the correction ring and the base plate to generate rotation. It is a non-active drive correction ring and base plate. grinding equipment, such as figure 1 with figure 2 shown. This set of surface grinding equipment consists of a cage, workpiece, base plate, correction ring, load block, po...

AI Technical Summary

Problems solved by technology

[0008] In order to overcome the problems of large thickness and low surface quality of the processing-deteriorated layer existing in the existing grinding and polishing equipment, the present invention provides a soft contact between the abrasive material and the workpiece to reduce the thickness of the processing-deteriorated layer while obtaining a higher Actively Driven Suspended Substrate Polishing Apparatus for Surface Quality
