CONCRETE diamond FAN grinding CUP


The elimination of burrs or defects in concrete formwork, or the elimination of coatings such as: bituminous layers, epoxy, paint or simply improving the flatness of the surface on which we are working, are the most common uses we can give to the diamond grinding cups for roughing type FAN CUP.

RUBI has designed the FAN CUP diamond grinding cups to obtain the best performance in all the roughing works on concrete surfaces.

The sintered segments are fixed to the high-performance steel body of the wheel by the laser welding technique, which is the strongest and most resistant.

The specific design of the steel body and the perpendicular arrangement of the diamond segments facilitate the removal of the remains of the roughing material and increase the cooling of the diamond grinding cup.

The FAN CUP diamond grinding cups allow the roughing of surfaces, and the grinding of edges in concrete. The degree of roughness left by these wheels is high and the working speed is higher than in a standard grinding cup, thanks to the double row of diamond segments.

The RUBI diamond grinding cups for the roughing of concrete, have been designed for use with a grinder, so they have a connection of Ø 22.2 mm. In addition, because of its small size, and the possibility of mounting them in a traditional grinder, they are ideal for working both horizontal and vertical surfaces.

In RUBI we know the way of working in each country in the world, we know the requirements of the ceramic setters and we have the knowledge of all the materials that are used for the installations and refurbishments. For these reasons RUBI is a recognised brand and clearly focused on a professional and very demanding sector. That is why RUBI puts at your disposal all the knowledge and experience to manufacture high precision tools. The high demands of our customers and the market makes us put all our experience to design tools and products for cutting and laying the ceramic tile in the most accurate way.
