1. How to set a gloss on the surface of stone
Stone is a kind of nonmetal、tough & fragile material. It should be through rough grinding、finish grinding and polishing to make the surface become level and bright .The sequence of grinding is :#50、#200、#1500、buff finally.

2. After grinding and polishing, the gloss of stone always can’t up to standard, Why?
It contains several reasons: Firstly, because of the bad quality of stone, it may has considerable holes, Secondly, due to the bad quality of abrasive, after rough grinding, the fine grains can’t wipe away the trace of rough ones, thus affect the final gloss. Thirdly, during operating, if the worker don’t control each procedure strictly, it also will affect the gloss. Finally, the quality of the polishing pads also affect the polishing results, after polished by the superior polishing pads, high gloss will be finished in a short time.

3. How to use the polishing pads correctly?
In order to attain the high gloss, the surface of stone should be formed a layer of reflector (Nami-thickness), the stronger light reflect, the higher gloss. At present, polishing pads are the elastic composition of rubber and plastic cement, polishing powder is the major ingredient of polishing pads, which plays an decisive role in it. During polishing, on the premise of giving out heat, due to polishing powder separate from binding preparation, and then form a thin layer of inorganic-transparent reflect membrane, the finer grinding of stone, the active of the surface, so the membrane will form easier and evener. Before polishing, the surface of stone should be washed clearly (keep them away from dirt),spilling a little water evaporating, repeating these several times, the surface of stone will become brighter. Due to the different ingredient of some polishing pads, just split ware once, and then polishing until finished.

4. During using the flexible polishing pads, they will make some slight relying on stone, or the color will become unclearly, Why?
It contains two reasons: The one is he flexible polishing pads consist of too much pigment, this factor is always unusual; the other is during operating, the water is insufficient, or the pressure on handle grinding machine is excessive.
