De no tenerla de fija al eje con una tuerca.Specifically, the head of the invention refers to a head for sanding or polishing with a conventional grinding machine, which has a plate-shaped configuration, which is provided with an internal threaded area in which it is screwed and fixed to the shaft. of the grinding machine, in case the support has a thread. Of not having it fixed to the shaft with a nut.

Estado de la tecnicaState of the art

Existen varias referencias en el estado de la tecnica de cabezales abrasivos del tipo indicado. En la mayorla de los casos presentan un disco de lija circular, en el centro del cual se practica una abertura que permite sujetarlo al eje de la herramienta.There are several references in the state of the art of abrasive heads of the type indicated. In most cases they have a circular sanding disc, in the center of which an opening is made that allows it to be attached to the axis of the tool.

Para evitar que se produzca un calentamiento excesivo del disco o del cabezal abrasivo durante la rectification, que pudiera dar lugar al deterioro de la pieza en la que se trabaja, o la proyeccion de virutas de material a alta temperatura que pueden ser peligrosas para el operario, se han ideado algunas soluciones: Por ejemplo, en el documento US3628292 se describe un disco abrasivo que presenta un cuerpo circular, provisto de una pluralidad de nervios y surcos que se alternan radialmente con esta finalidad. Por su parte en el documento ES2188015 se describe un disco abrasivo con un soporte y una gran cantidad de laminas con revestimiento abrasivo, sujetas por uno de sus bordes a la parte exterior del soporte y alineadas siguiendo un clrculo centrado en el eje del disco, de tal manera que laTo prevent excessive heating of the disc or abrasive head during rectification, which could lead to deterioration of the workpiece, or the projection of high temperature material chips that can be dangerous for the operator Some solutions have been devised: For example, in US3628292 an abrasive disc is described that has a circular body, provided with a plurality of ribs and grooves that alternate radially for this purpose. For its part, in document ES2188015 an abrasive disc with a support and a large number of sheets with abrasive coating are described, attached by one of its edges to the outside of the support and aligned following a circle centered on the axis of the disk, of such that the

En cuanto a la distribucion de los sectores que conforman este cabezal, alternativamente son, o bien de material abrasivo y no abrasivo, o bien de materiales abrasivos diferentes. Combinando adecuadamente sectores abrasivos y no abrasivos, o abrasivo de distintos grados, se consiguen acabados hasta ahora no logrados con discos uniformes de un solo material y caracterlsticas.As for the distribution of the sectors that make up this head, they are alternatively either abrasive and non-abrasive, or different abrasive materials. By properly combining abrasive and non-abrasive sectors, or abrasives of different grades, finishes hitherto not achieved with uniform discs of a single material and characteristics are achieved.

En una realizacion alternativa al menos alguno de los sectores esta constituido por al menos una lamina de material abrasivo, que se alternan con otros sectores que pueden ser de material abrasivo o no abrasivo.In an alternative embodiment at least some of the sectors is constituted by at least one sheet of abrasive material, which alternates with other sectors that can be of abrasive or non-abrasive material.
