Latest Patents

One of his latest patents is for abrasive articles comprising a blend of abrasive particles. This invention provides an abrasive article, particularly a cut-off wheel, that features a mixture of rare earth oxide modified abrasive grains and alpha alumina seeded or iron oxide nucleated abrasive grains. The rare earth oxide is present at a level between about 0.1 wt-% to 10 wt-% of the abrasive grain, based on a theoretical oxide basis. In one embodiment, the rare earth oxide modified abrasive grains are designed as rods.

Another significant patent by Abrahamson is a method of making a rotary brush with removable brush elements. This rotary brush includes brush elements that are disposed on a hub in a radial display. The brush elements consist of a resiliently flexible element, allowing the brush to deflect at a greater angle from a rest position than the angle of deflection of the bristles when the hub is rotated with the bristles in contact with the workpiece.
