Diamond Dressers Now Certified to Micro-Precision Tolerances

Meister's new micro-precision CNC Dressing Tools are suited for grinding applications with form tolerances down to 2 µm.

Suited for truing and sharpening of grinding wheels used with automotive and aerospace bearing races, high-precision gear grinding, plunge grinding of fuel injection armatures and needles and other demanding applications."

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

Bruce Northrup, Vice President and General Manager of Meister Abrasives USA said, "To dress grinding wheels for ultra-high 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 micro-precision certified cDD dressers is the result of a multi-year R&D project which culminated in a major investment in manufacturing, measurement and verification systems."

This degree of certified precision makes micro-precision 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.

"Meister Abrasives broke into new territory with the introduction of diamond dressers that excelled both at truing and sharpening CBN wheels," said a spokesperson. 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.

According to Meister, the cumulative advantages of the cDD technology for both dressing and subsequent grinding processes are:

  • Superior truing (accurate and consistent profile generation on the grinding wheel)
  • Superior sharpening (does not dull the grinding wheel)
  • Low dressing forces
  • The grinding wheel cuts better and achieves better part quality
  • Lower dress in-feed or higher skip dress is possible
  • The dressing tool stays sharp (no conditioning required).
