A microabrasive tool is formed from a slurry including liquid, abrasive grains, a bonding material, and a polymer (22) for example, gellan gum. The slurry is cast in a mold, and the polymer is ionically cross-linked. Cross-linking the polymer fixes the structure (24) of the bonding material and the abrasive grains, wherein the abrasive grains are dispersed substantially uniformly within the bonding material. The ionically cross-linked structure (24) of bonding material and abrasive grains can then be fired to form a microabrasive tool.
L'invention concerne un outil micro-abrasif formé à partir d'une suspension comprenant un liquide, des grains abrasifs, une matière de liaison et un polymère (22) par exemple une gomme gellane. La suspension est moulée dans un moule et le polymère est soumis à une réticulation ionique. La réticulation du polymère fixe la structure (24) de la matière de liaison et des grains abrasifs, les grains abrasifs étant dispersés de manière sensiblement uniforme dans la matière de liaison. La structure (24) à réticulation ionique de la matière de liaison et des grains abrasifs peut ensuite être chauffée pour former un outil micro-abrasif.
