How to polish stones

After selecting the stone to be polished, put the stone in a suitable container, completely submerge it with clear water and soak it for two or three days. The reason for this is to fully dissolve the floating soil on the stone and loosen the dirt attached to the surface.

Step 2: Brush your teeth.

After the stone is soaked, scrub the surface and crevices of the stone (steel brush is optional for hard stone, and nylon brush is best for soft stone), and then dip the stone in water to clean it.

After soaking and brushing, the stone can be polished. Be patient at this step. According to the thickness of stone texture, choose the corresponding grinding head and polish it carefully in the order of coarse first and fine second.

Classification of common stone polishing:

1, mechanical polishing

Mechanical polishing is a polishing method to obtain a smooth surface by cutting and plastic deformation of the material surface. Generally, it is oilstone strips, wool wheels, sandpaper, etc. Both are adopted, and manual operation is the main method. For special parts such as the surface of rotating body, auxiliary tools such as turntable can be used, and ultra-precision grinding and polishing method can be used for those with high surface quality requirements.

2. Chemical polishing

Chemical polishing is to make the micro-convex part of the material surface dissolve before the concave part in the chemical medium, so as to obtain a smooth surface. The main advantages of this method are that it does not need complicated equipment, can polish workpieces with complicated shapes, can polish multiple workpieces at the same time, and has high efficiency. The core problem of chemical polishing is the preparation of polishing solution. The surface roughness obtained by chemical polishing is generally 65438±00 μm m. ..

3, electrolytic polishing

The basic principle of electrolytic polishing is the same as that of chemical polishing, that is, by selectively dissolving the tiny protrusions on the surface of the material, the surface is smooth. Compared with chemical polishing, it can eliminate the influence of cathode reaction and has better effect.
