Meister Abrasives USA, Inc. has introduced a new generation of cDD Diamond Dressers that deliver certified tool radius tolerances, which are essential for most demanding microprecision grinding applications. The radius form tolerance of these new microprecision diamond dressers can be certified accurate to within 2μm (+/-0.001mm) if the application requires.

Bruce Northrup, vice president and general manager of Meister Abrasives USA said, "To dress grinding wheels for ultrahigh precision applications the user needs to have a precise, certified radius value to plug into his CNC dressing program. Very few dressing wheel manufacturers have been able to achieve this degree of certified precision. Meister's introduction of microprecision certified cDD dressers is the result of a multiyear R&D project which culminated in a major investment in manufacturing, measurement and verification systems. These have enabled Meister Abrasives to achieve an order of magnitude improvement in the accuracy and precision for these unique dressers."

This degree of certified precision makes microprecision cDD Diamond Dressers suitable for the CNC truing and sharpening of grinding wheels used in manufacturing automotive and aerospace bearing races, high-precision gear grinding, plunge grinding of fuel injection armatures and needles, and other critical grinding applications that require form tolerances as tight as 2 microns.

These 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 matrix.
