Abstract
LOS PERFILES DE LAS ROSCAS EN LAS MORDAZAS DE UN MANDRIL, COMO POR EJ. UN MANDRIL DE TRES MORDAZAS, ESTAN MODIFICADAS DE TAL FORMA QUE AL MENOS UN EXTREMO DE LOS SEGMENTOS DE LA ROSCA DE LA MORDAZA SE CURVAN HACIA AFUERA DESDE LAS ROSCAS SOBRE LA TUERCA QUE HACE FUNCIONAR LAS MORDAZAS. ESTO EVITA QUE LOS BORDES EXTREMOS DE LOS SEGMENTOS DE LA ROSCA DE LA MORDAZA SOCAVE LAS ROSCAS DE LA TUERCA CUANDO LA TUERCA SE HACE GIRAR PARA HACER FUNCIONAR LAS MORDAZAS
