Abstract

SE PRESENTA UNA PIEZA DE INSERCION DE CUERPO SINTERIZADO PARA CORTAR QUE COMPRENDE UNA CAPA INTERMEDIA (24, 32) QUE CONSTA DE CUALQUIER MATERIAL DE CARBURO CEMENTADO, UN METAL FERROSO Y UN METAL DE ALTO PUNTO DE FUSION, Y UNA PRIMERA CAPA (25A, 33A) Y UNA SEGUNDA CAPA (25B, 33B) QUE CONSTAN DE CUERPOS DUROS AGLUTINADOS QUE CONTIENEN NITRURO DE BORO CUBICO O DIAMANTE, QUE ESTAN DISPUESTAS SOBRE POSICIONES QUE MANTIENEN LA CAPA INTERMEDIA (24, 32) DESDE ARRIBA Y DESDE DEBAJO RESPECTIVAMENTE Y UNIDAS A LA CAPA INTERMEDIA MEDIANTE AGLUTINACION, LA PIEZA SE FORMA DE MANERA QUE SUS SUPERFICIES FRONTAL Y TRASERA DEFINAN CARAS DE CORTE. TODAS LAS PARTES DELANTERAS (R) Y LOS LADOS QUE SE REFIEREN AL CORTE ESTAN FORMADOS SOBRE LA PRIMERA CAPA (25A, 33A) Y LA SEGUNDA CAPA (25B, 33B), MIENTRAS QUE LA CAPA INTERMEDIA (24, 32) SE FORMA PARA INCLUIR EL CENTRO DE GRAVEDAD DE LAS CARAS CORTANTES ASI COMO EL DE LA PIEZA DE INSERCION COMPLETA. ADEMAS, SE FORMAN CAPAS DE REVESTIMIENTO QUE CONSTAN DE UN NITRURODE UN ELEMENTO QUE PERTENECE AL GRUPO 4A, 5A O 6A DE LA TABLA PERIODICA SOBRE LAS SUPERFICIES DE LAS CARAS CORTANTES Y DE LOS FLANCOS. DE ACUERDO CON ESTA ESTRUCTURA, ES POSIBLE SUMINISTRAR UNA PIEZA DE INSERCION DE CUERPO AGLUTINADO PARA CORTAR QUE TIENE UNA VIDA PROLONGADA Y ES EXCELENTE SUS CARACTERISTICAS ECONOMICAS TALES COMO EL COSTE DE MANUFACTURACION.
