  • BONDED ABRASIVE ARTICLE AND METHOD OF MAKING THE SAME
    Publication number: 20230356360
    Abstract: An abrasive article can include a body including a bond material, abrasive particles, and a plurality of pores, wherein the bond material can comprise a vitreous material. In one embodiment, an average particle size of the abrasive particles can be between 0.1 microns to 5 microns, and a porosity of the body may be between 40 vol % to 70 vol %, wherein the porosity may define an average pore size (D50) of at least 0.1 microns and not greater than 5 microns.
    Type: Application
