Description

Technical Field

[0001] The present invention relates to the technical field of gem workpiece processing settings, and specifically provides an integrated device for fine grinding and polishing of gem workpieces. Background Art

[0002] Gem workpieces refer to gem materials that have been processed through cutting, grinding, polishing and other processing techniques to meet specific industrial or decorative needs. The processing of gem workpieces needs to consider factors such as the hardness, brittleness, and optical properties of the gems to ensure their performance and durability in applications. Among them, gem round bars belong to a type of gem workpiece. When processing gem round bars, fine grinding and polishing equipment is required to grind and polish the two end faces of the gem round bars;

[0003] In the sapphire substrate grinding device with the Chinese patent application number 201611265348.9, this invention includes: a frame having a rotating shaft; a grinding table provided on the frame and driven by the rotating shaft to rotate. The grinding table has a grinding surface for grinding the sapphire substrate located on the grinding table; a ceramic disk located on the grinding surface, driving the sapphire substrate to move relative to the grinding surface. The pressure exerted by the ceramic disk on the central position of the sapphire substrate is greater than the pressure exerted on the edge position of the sapphire substrate. By using the pressure exerted by the ceramic disk on the central position of the sapphire substrate being greater than the pressure exerted on the edge position of the sapphire substrate, the grinding force of the grinding surface on the central position of the sapphire substrate is greater than that on the edge position, so as to achieve the technical effect that the center of the sapphire substrate is thin and the middle position is thicker, and further make the surface of the sapphire have a certain curvature.

[0004] When using fine grinding and polishing equipment to grind and polish the two end faces of the gem round bar, it is necessary to install the gem round bar into the mounting frame, install the mounting frame above the polishing equipment, and the sandpaper at the bottom of the polishing equipment rotates to polish the end face of the gem round bar. When fine grinding and polishing, different mesh numbers of sandpaper are required to grind the end face of the gem round bar in sequence. During the grinding process, it is inconvenient to replace sandpaper with different mesh numbers, which affects the grinding efficiency. Summary of the Invention
