We offer tailor-made solutions for a wide range of applications, machines and workpieces in the area of face and finegrinding. Krebs & Riedel manufactures double disc grinding wheels up to 1500 mm outer diameter made of DIA and CBN in vitrified bond for the effective creation of flat surfaces with a high surface quality and shape tolerance for a wide range of different materials. The range includes grinding tools in different segmentation for single and double disc grinding machines with and without planetary kinematics. Compared to other systems, the vitrified bond system by Krebs & Riedel allows the production of very free cutting and porous coating structures. This results in a significant increase in productivity.
