Hybrid technology extended to stationary dressing
10 January 2014
With the introduction of the new series of Meister hDD (Hybrid Diamond Dressing) and cDD (Hybrid matrix with CVD diamond inserts) stationary dressing tools, Master Abrasives provides benefits for aluminum oxide and other conventional wheels on grinding machines that are not equipped with a rotary dresser.

Sales and marketing director, Paul Batson, says: "Early users of these products report that they are obtaining sharper, faster cutting wheels that last longer with stationary dressing tools that do not have to be re-lapped or returned to the manufacturer for repositioning of the diamond insert.”
These dressing tools rely on an advanced hDD bonding matrix that combines the toughness of metal bonding with the natural porosity of a vitrified bond structure, comparable to the porosity found in vitrified CBN grinding wheels. The advantages claimed for this combination include more efficient dressing cycles that lead to more consistent conventional grinding wheel performance, increased intervals between dresses, improved longevity of the dressing tool itself, and elimination of the need to change out the dressing tool for re-conditioning.
