Grinding of marble gives a possibility to get a matte surface of this excellent stone with uniform roughness. The roughness of relief when grinding and restoration is no more than 0,5 mm. Grinding of marble is performed with special equipment – rotor and grinding machines which are equipped with diamond or abrasive tools.

• Grinding of marble. It’s performed immediately ahead of polishing. It allows removing scratches which appeared after leveling grinding.
Materials and equipment needed for grinding of marble:
Grinding machines;
Diamond disks of various degrees of grit and abrasive wheels;
Rotor machines;
Mechanical tools;
High quality polymer compounds when finishing works.
Restoration of battered surfaces from marble is performed in several steps. Firstly a degree of damage is estimated. During the stone inspection they detect attritions, spots, cracks, chips and other defects. The procedure of grinding of marble surface is performed with the help of diamond disks.
