A magnetorheological polishing device for metal surface treatment and using method thereof

Abstract

The present invention relates to the technical field of metal surface polishing, in particular to a magnetorheological polishing device for metal surface treatment and a method for using the same. The device includes an equipment body, wherein a first telescopic cylinder is vertically arranged in the equipment body , the bottom of the first telescopic cylinder is provided with an X-axis adjustment assembly along the X-axis direction, the first telescopic cylinder is driven and adjusted by the X-axis adjustment assembly, and the top end of the first telescopic cylinder is passed through the first connecting assembly The vertical connection is provided with a rotatable grinding wheel; in the device, the mirror surface to be processed is inverted so that the grinding wheel to be processed is below the mirror surface, and the debris generated during the polishing process can fall under the action of gravity to avoid reattachment On the mirror surface, it is avoided that the debris is involved in the area to be polished during mirror polishing, resulting in cracks on the mirror surface, and the mirror polishing effect is improved.

Description

technical field [0001] The invention relates to the technical field of metal surface polishing, in particular to a magnetorheological polishing device for metal surface treatment and a method for using the same. Background technique [0002] The subtle unevenness of the mirror surface will affect the reflection of light, which requires grinding and polishing. Ordinary mirrors used in daily life can be polished with sandpaper, or treated with abrasive pastes of different particle sizes, but for the use of metal materials as the reflective mirror surface For high-end telescopes, manually grinding the mirror surface will result in low grinding efficiency and uncontrollable accuracy. The mirror surface obtained by the above processing method is difficult to meet the design requirements. [0003] Therefore, the current mirror polishing is generally done by computer, which is called computer-controlled mirror forming technology. After computer technology is adopted, the measuremen...

AI Technical Summary

Problems solved by technology

[0004] At present, the mirror polishing basically uses a grinding disc, and sprays the abrasive liquid with tiny abrasive particles between the grinding disc and the mirror surface, rotates the grinding disc parallel to the mirror surface, and sticks to the mirror surface to apply pressure, so that the mirror surface is polished. However, this method still has disadvantages. Grinding by applying pressure will damage the mirror surface, and there will be many cracks of a few microns below the surface, which will affect the reflection effect of the mirror surface.
