Diseño y construcción de una pulidora metalográfica de 4 servicios automatizados a implementar en el Laboratorio de Ingeniería de Materiales de la Facultad de Mecánica

Abstract

The objective of the present degree work called: "Design and construction of a metallographic polishing machine with 4 automated services to be implemented in the materials engineering laboratory of the Faculty of Mechanics" has been the implementation of a metallographic polishing machine with 4 automated services for the theoretical-practical development in the Materials Engineering laboratory in the Faculty of Mechanics whose purpose has been the fulfillment of the objectives set out in a study on the different methods of grinding-polishing operations in the process of preparation of metallographic specimens, thus replacing the manual process performed so far in the laboratory. Initially, the basic principles of the metallographic technique were analyzed to determine the type of grinding machine, abrasives, disc rotation speeds, necessary to guarantee the achievement of the proposed objectives, followed by the identification of the different existing polishing machines where the advantages and disadvantages of each one was analyzed in terms of operation, ease of operation, results, etc. During this analysis we proceeded to the construction of the polishing machine, of 4 automated services in which the specimens rotate at high speeds, to finally implement the metallographic polishing machine and analyze the results obtained, making a comparison between the implemented machine and those that previously existed in the laboratory. With the implementation of this machine the capacity of the laboratory is optimal because the time in which students develop these tests is less, and therefore the results obtained in the analysis of the specimens are optimized, which guarantees the learning process of the students of the Faculty of Mechanics.
