Abstract

Una máquina de pulir que comprende por lo menos un cabezal rotatorio (1), conectado a través de un collarín (2) al extremo de un eje impulsor, portando la cara de trabajo del cabezal rotatorio una pluralidad de sectores (3) de amolar, sostenidos articulados en brazos (4) conectados al cabezal rotatorio (1) en posiciones angulares uniformemente espaciadas, presentando cada sector (3) de amolar una estructura laminada que incluye una porción (5) conformada como un mango de un material rígido y mecánicamente resistente encajada dentro de una cavidad alojadora del brazo (4) de sostén, por lo menos una almohadilla resiliente por lo menos en parte hecha de elastómero (6, 8) interpuesta entre una cara de dicha porción (5) de mango y un cuerpo aglomerado de partículas abrasivas y de una resina aglutinadora (9, 10) que presenta una cara de trabajo sustancialmente cilíndrica, caracterizada porque dicha cara de trabajo cilíndrica es discontinua y está definida por una pluralidad de caras extremas de tantas protuberancias (9) de dicho aglomerado que se elevan desde una capa (10) de base relativamente delgada y flexible de dicho aglomerado que incorpora fibras de refuerzo.A grinding machine comprising at least one rotating head (1), connected through a collar (2) to the end of a driving shaft, the working face of the rotating head carrying a plurality of grinding sectors (3), held articulated in arms (4) connected to the rotary head (1) in uniformly spaced angular positions, each sector (3) presenting a laminated structure that includes a portion (5) formed as a handle of a rigid and mechanically resistant material fitted within a housing cavity of the support arm (4), at least one resilient pad at least partly made of elastomer (6, 8) interposed between a face of said handle portion (5) and a particle agglomerated body abrasive and of a binder resin (9, 10) having a substantially cylindrical work face, characterized in that said cylindrical work face is discontinuous and is defined by a plurality of c extreme saws of so many protrusions (9) of said agglomerate that rise from a relatively thin and flexible base layer (10) of said agglomerate incorporating reinforcing fibers.
