Our Floor Grinders can be used for grinding and polishing marble, granite and concrete. Our heavier duty machines are used to grind concrete and can handle much more stress and will have more power to drive the unit as concrete has a much higher sliding friction than either marble or granite.
Marble and Granite grinding is completed wet because of the lower levels of friction. In fact some types of marble will spark when it is ground dry, causing deep damage to the marble surface.
All our concrete grinders use either diamond grinding cup wheels or some sort of abrasive to grind or polish such as diamond tools or Silicon carbide and for polishing we use diamond polishing pads.
Concrete is usually ground dry for convenience, because it can be done with fewer people than wet grinding although a filter-equipped vacuum is needed to capture the fine dust produced.
