Abstract

EL TALADRADOR DE ROCA CONSTA DE UN MANGO (1) Y UN CABEZAL DE TALADRADO (2) Y ESTA DOTADO CON UNA PLACA DE CORTE (4) EN LA SUPERFICIE FRONTAL (3) EN LA DIRECCION DE AVANCE DEL CABEZAL DE TALADRADO (2) ASI COMO UNA ESPIGA DE CORTE (5). EL DIAMETRO SOBRE EL QUE SE ENCUENTRA LA PLACA DE CORTE (4) Y EL DIAMETRO SOBRE EL QUE ESTA LA ESPIGA DE CORTE (5), FORMAN UN ANGULO DE DIFERENCIA DE 90 . A TRAVES DE LA DESVIACION DE LOS ANGULOS DE AMBOS DIAMETROS SE PUEDE PERMITIR UN AGRANDADO DE LA RANURA DE TRANSPORTE (6).
