Abstract

Abrasive disc on flexible, improved support, of the type that has several strata or superimposed layers of abrasive particles bonded with glue or with a resin to a support material, whose abrasive material is distributed in main mode and occupying most of the useful surface, along one or more concentric circular ring areas, grouped in each one of them in a series of equal, adjacent rhomboid plant portions, with the inner curved and curved outer sides, equidistant with one of their diagonal oriented radially, depending on the diameter of the disc in the fringe border with the periphery and in the free space between the triangular ends of the different diamonds, another zone of agglomeration of truncated triangular area with its two lateral sections its curved base and also and located directly to the inter-diamond part of the ring set of them more inte when starting from the center circle free of abrasive for mounting the disc, there are a series of zones with abrasive material of triangular isosceles configuration whose equal sides adopt curved convex development, and its base is curved, being defined between these protruding configurations of abrasive, two bundles of spirals of development in spiral to the right and left whose stroke starts from the center of the disc, at angular equidistance, suitable for centrifugal evacuation in spiral vortex of liquid flow and/or gaseous cooling or for its centripetal admission simultaneously, during rotation of the disk.
