A marble diamond cup grinder is a tool specifically designed for processing relatively soft and porous natural stones like marble. It has some key differences from discs used for concrete or granite.
Features of Diamond Cup Grinding for Marble
Marble is a softer and more delicate stone than granite, so the cup grinders used to work with marble are designed to work without damaging the surface.
Softer Bond Matrix: The metal bonds used in marble cup grinders are generally softer than those used for granite. This is because marble is less abrasive, and the bond itself must be worn down to expose the diamonds regularly. A bond that is too hard may not cut smoothly on marble and may leave "burn" marks on the surface.
Number and Shape of Segments: They can often have more, thinner segments to provide a smoother finish. This puts less stress on the material, reducing the risk of cracking or breaking.
Turbo Segments: Turbo type cup grinders are preferred to provide both a better finish and effective cooling, especially on sensitive surfaces such as marble.
Wet Use: A large portion of marble processing is performed with water, both to control dust and reduce frictional heat. Therefore, most cup grinding wheels designed for marble are suitable for wet use. Wet grinding also helps enhance the marble's gloss and prevent microcracks from forming on the surface.
Areas of Use
Marble diamond cup grinding wheels are mainly used in the following applications:
Leveling of Marble Floor Surfaces: Eliminating the height differences (level differences) that occur after the installation of marble floors and preparing the surface for polishing.
Restoration of Old Marble Surfaces: Revitalizing marble countertops, floors and wall coverings that have become dull, scratched or stained over time.
Edge Shaping and Profiling: Rounding the edges of marble countertops or coverings or giving them the desired shape.
