Title (EN) PLACEMENT OF ABRASIVE PARTICLES FOR ACHIEVING ORIENTATION INDEPENDENT SCRATCHES AND MINIMIZING OBSERVABLE MANUFACTURING DEFECTS
(FR) PLACEMENT DE PARTICULES ABRASIVES POUR OBTENIR DES RAYURES INDÉPENDANTES DE L'ORIENTATION ET RÉDUIRE AU MINIMUM DES DÉFAUTS DE FABRICATION OBSERVABLES
Abstract:
(EN) The present invention includes an abrasive tool comprising a substrate and plurality of abrasive grains arranged in a pseudo-random pattern on the substrate. The abrasive grains cover in the range of 10% to 30% of the substrate surface, and in some instances, the arrangement of abrasive grains demonstrate improved orientation independence and homogeneity in distribution of abrasive grains.
(FR) La présente invention concerne un outil abrasif comprenant un substrat et une pluralité de grains abrasifs agencés selon un motif pseudo-aléatoire sur le substrat. Les grains abrasifs recouvrent dans la plage de 10 % à 30 % de la surface du substrat et, dans certains cas, l'agencement de grains abrasifs présente une indépendance à l'orientation et une homogénéité améliorées dans la répartition des grains abrasifs.
