EPOXY-FIBER PCD diamond grinding cup


The roughing is a fundamental process in the works of rehabilitation, renovation and repair of surfaces, and to be able to obtain the best results it is necessary always to use the appropriate tools for each case.

Within the range of diamond grinding cups for RUBI roughing, the specialized professional can find the specific ones for surfaces with synthetic coatings, especially paints and epoxy resins.

The main feature of this diamond grinding wheel is that it uses polycrystalline diamond segments (PCD) that are fixed to the high-performance steel body by means of the high-frequency welding technique. This steel body has a series of holes to facilitate the evacuation of the remains of roughing material and increase the cooling of the diamond grinding cup.

The final result that leaves the PCD grinding cup for epoxy or fibres is a high roughing, perfect for leaving the pore open and repainting or reapplying a new coating film.

The RUBI PCD diamond grinding cups for the roughing of epoxy or fibres, have been designed for use with a grinder, so they have a connection of Ø 22.2 mm.

Adhesive residues or other acrylic coatings can also be removed with the PCD RUBI diamond grinding cups.
