Istone crafts will be oxidized and rusted to varying degrees after being exposed to or affected by the air environment. Not only will the finished stone sculpture oxidize and rust after long-term use, but also after some mechanical processing such as welding, stamping, curling, heat treatment, etc., there will also be a black oxidation deterioration and hardening layer on the surface of the stone carving workpieces, which may form small visible or invisible patches. Burrs and sharp corner burrs.
For some small burrs and sharp corners on the surface of stone sculpture on the market, if they are removed mechanically, some can be removed and some cannot be removed. This will also have an impact on the stone carving workpieces and affect the effect of the stone carving workpieces. In order to solve these problems, it is necessary to use some methods to grind and polish stone carving products. Generally speaking, the grinding methods currently used include mechanical grinding and polishing, chemical grinding and polishing, compound grinding and polishing, etc.
There are now four types of mechanical grinding and polishing, namely grinding wheel polishing, sand blasting polishing, grinding polishing and extrusion polishing. Chemical grinding is also divided into electrolytic chemical grinding and polishing and chemical grinding and polishing. Composite grinding and polishing is a combination of mechanical grinding and chemical grinding and polishing.
Due to the different use environments of stone sculpture, the requirements for the surface of metal workpieces are also different. stone sculpture use different grinding methods to meet the needs of use. Mechanical grinding and polishing are processes that remove the convex parts of the grinding surface through cutting, abrasion or plastic deformation to obtain a smooth and bright stone surface.
Chemical grinding and polishing is a method of immersing stone sculpture in special chemical solutions composed of various solutions, relying on the chemical rust on the surface of the stone sculpture to obtain a smooth and bright stone sculpture surface.
Electrolytic chemical grinding and polishing, also known as composite polishing, is a method of immersing stone sculpture in a special chemical solution composed of various ingredients and dissolving the surface of the stone sculpture through current energy.
