Meister Abrasives has introduced a revolutionary new cDD (CVD-tipped Diamond Dresser) technology producing rotary dressing tools that hold their profiles better and their sharpness longer than other dressing technologies to date. The cDD dressing tools rely on a unique structure in which high-quality CVD diamond inserts are strategically embedded within Meister’s hDD porous hybrid-bond diamond matrix. As a result of this combination, users are no longer forced to choose a dressing tool that is optimized either for truing or sharpening; cDD dressing tools excel at both. Bruce Northrup, General Manager of Meister Abrasives, USA, said, “The choice of a dressing tool and the parameters under which it is used has a direct impact on the profile and cutting behavior of the grinding wheel and therefore the resulting surface finish, geometry, and quality of the ground components. The challenge for the dressing tool manufacturer is to produce a dressing tool that is good at both truing and sharpening the grinding wheel at the same time. Unfortunately currently available dressing tools are typically good at either truing or sharpening, but not both.” He explained that metal bonded dressing tools and handset diamond dressing tools tend to be good at truing and profile generation but underperform when it comes to sharpening. Vitrified (ceramic) bonded dressing tools, on the other hand, sharpen well but are generally not as good for truing or generating profiles because they lose their edges quickly. Meister’s cDD technology answers both requirements by bringing the best qualities of metal, vitrified, and handset diamond into one technology.
