The November 2016 issue of Manufacturing Engineering Magazine highlights Meister Abrasive’s 3D technology in a Round-up article about the new generation of ultra-porous grinding wheels.
In this article: “Maybe it’s time to try some ‘Swiss Cheese,” the author, Ed Sinkora says:
Meister’s 3D Abrasives Technology combines grits as small as 10 µm in a matrix with pores as big as 500 µm, enabling a tiny wheel on a quill to grind the internal bore of this fuel injector nozzle without deflection, for a 7x improvement in cylindricity and taper.
“These days the most important theme in super abrasive grinding wheel development isn’t the abrasive, it is the bond. The diamond or CBN grains do the cutting, but the bond plays a decisive role in exposing the grains to the workpiece and enabling coolant to remove heat. Without exposed grains the wheel won’t cut. And without porosity in the bond, coolant won’t be able to flush away material with the heat that would otherwise damage the workpiece, not to mention the wheel. So while no one seems to be touting new super abrasives, all the high-tech players are experimenting with new, open bonds.”
Sinkora goes on to cite Meister’s 3D technology as “the clearest example of a recent improvement in bond technology.”
