Implementación de un procedimiento metodológico para la elaboración de piezas por bruñido con rodillo simple // Implementation of a methodological procedure for parts elaboration by single roller burnishing.
Abstract
En el presente trabajo se exponen los fundamentos y los resultados de investigaciones realizadas sobre
la operación secundaria de acabado superficial de piezas conocida como bruñido por rodillo simple.
Se realiza una investigación experimental en piezas simétrico-rotativas de acero AISI 1045 en un torno
paralelo convencional con una herramienta de bruñir mono rodillo construida al efecto, donde se
toman en consideración las variables más influyentes en el bruñido por rodillo simple: fuerza
compresiva, avance y número de pasadas de la herramienta bruñidora. Se obtienen los modelos
empírico-matemáticos que describen los efectos de estas variables en el incremento de la dureza y la
calidad superficial final de la pieza, así como en la disminución del diámetro exterior y en la
profundidad de la capa endurecida. Como resultado más importante de este trabajo, se desarrolla un
procedimiento metodológico para la elaboración de piezas mediante este tipo de tratamiento
mecánico por deformación plástica superficial, que permitirá la creación y difusión de una disciplina
tecnológica sobre un proceso de fabricación que posee ventajas y que está poco difundido en las
empresas metalmecánicas.
Palabras claves: bruñido por rodillo simple, deformación plástica superficial, dureza superficial, rugosidad
superficial, acero AISI 1045.

Abstract
In the present work the foundations and the results of the investigation for the secondary operation of
superficial finish (single roller burnishing) are presented. The most important aspects of the superficial
plastic deformation process for improving superficial finish are approached
An experimental investigation in symmetrical-revolving pieces of steel AISI 1045 in a conventional
parallel lathe with a burnishing tool of single roller built to the effect is carried out. The most
influential variables were took in consideration: compressive force, feed and number of passes of the
burnishing tool. The empiric-mathematical models are obtained to describe the effects of these
variables in the increment of the hardness and the superficial quality end of the piece, as well as in the
decrease of the external diameter and in the depth of the hardened layer.
The most important result of this work is the proposal of a methodological procedure developed for
the elaboration of parts by means of this type of mechanical treatment for superficial plastic
deformation that will allow the creation and diffusion of a technological discipline about a
manufacturing process that possesses advantages and that is little diffused in metalworking shops.
Key words: single roller burnishing, superficial plastic deformation, superficial hardness, superficial
roughness, steel AISI 1045
