    摘要： A radial grinding tool for a machining center utilizing through-spindle coolant is disclosed and includes a main body having a central longitudinal axis, a spindle extending along the central longitudinal axis, a disc-shaped wheel member located at an end of the spindle and including a working surface at a periphery of the wheel member, and a passageway extending through the main body configured to accommodate a flow of coolant. The tool includes an impeller attached at a lower side of the wheel member and having a plurality of blades that are configured to impart a force against the coolant to reshape the flow of coolant into a generally flat stream and redirect and drive the coolant radially outward from the central longitudinal axis to the working surface.

    摘要： A method of making conglomerate abrasive particles includes: providing agglomerate abrasive particles comprising mineral particles in a first vitreous binder; combining the agglomerate abrasive particles with a second vitreous binder material precursor to form precursor conglomerate abrasive particles; and heating the precursor conglomerate abrasive particles to convert the second vitreous binder material precursor into a second vitreous binder, different from the first vitreous binder, thereby forming the conglomerate abrasive particles. The first vitreous binder differs from the second vitreous binder by at least one of: i) elemental composition, or ii) an intrinsic physical property; and wherein the conglomerate abrasive particles can pass through a testing sieve having one-millimeter openings. Conglomerate abrasive particles preparable by the method, and abrasive articles containing them, are also disclosed.
