Coarse grinding procedures in stone polishing

Seeing the scarred marble floor, the first reaction of many people is that the texture of the stone is so strong, how can it be easily intermittent? In fact, the stone was not as strong as expected. If the stone is not maintained during processing, transportation and installation, it is easy to damage the surface of the stone. After the stone is damaged, it will greatly affect the appearance. At this time, stone polishing and stone repair can make it return to its former glory.

Before polishing marble, glue treatment should be carried out according to the material. After the glue treatment is completed, polishing is carried out. Stone polishing is usually carried out according to the rough grinding procedure → semi-finishing → fine grinding → fine grinding → polishing. Some rough grinding steps can be omitted, mainly depending on whether the rough stone surface has been preliminarily treated. Coarse grinding: requires deep sharpening, high grinding efficiency, rough grinding lines and rough grinding surfaces. It is mainly to remove the saw blade marks left by the previous process of the stone, and polish the flatness and shape of the surface of the stone in place; the single-line diagram should be roughly ground, and a 0.5mm fine grinding and water grinding allowance should be left during rough grinding. Semi-fine grinding: remove rough grinding marks, form new thin lines, and make the stone surface smooth; fine grinding: after fine grinding, the patterns, particles and colors on the stone surface are clearly displayed, the surface is fine and smooth, and the initial luster is weak; fine grinding: fine grinding: fine grinding There are no marks on the surface of the grinding stone. The surface is getting smoother and smoother, and the gloss can reach more than 55 degrees.

Splicing, grinding and polishing. The lines are spliced ​​according to the installation drawing, and the color distribution on the surface of the lines ensures the good effect of color and pattern. After water grinding 500 lines, uniformly number them according to the requirements of the installation drawing, and then disassemble and polish. In this way, the polishing and polishing lines will not be uneven; when the interface is dislocated, the grinding of the transition section should extend the distance, the longer the better, check the straightness with a ruler; when polishing marble, carefully check each abrasive or diamond sanding discs after polishing Polished condition of smooth surface. After polishing the next abrasive, the traces of the abrasive should be covered.
