Diseño y construcción de una pulidora metalográfica para el laboratorio de ingeniería mecánica de la Universidad Santo Tomás Seccional Tunja.

Abstract

The laboratory of the Faculty of Mechanical Engineering of the Santo Tomas Tunja University has limited access to this essay, because the existing teams in various entities remain busy, being at the forefront in this type of practice allows students to have a greater understanding about existing materials and structures. The Universidad Santo Tomás Seccional Tunja has a basic metallography equipment in the laboratories, which requires a technological update, with the aim of facilitating the development of the polishing process of specimens, giving polishing results according to the test that demand a specular surface of greater precision. Taking into account that the University must ensure the safety and quality of the practical activities of its students and teachers, it is important that the laboratory has the appropriate tools to prevent accidents and allow a good performance of the academic year for which it was created. , therefore, the existence of a team like the one proposed in the present work is necessary. The project reflects the application of the knowledge acquired by the executors as students of Mechanical Engineering of the University of Santo Tomás de Tunja throughout the entire career, putting into practice the received chairs such as: design, resistance of materials, maintenance, automation and control, among others; in such a way that the result obtained through the completion of the project is a fully functional machine, which adapts to the conditions imposed by the environment, whose design and construction was made taking into account parameters of economy and safety. To optimize metallographic preparation operations, it is necessary to have a machine that allows to develop a better polishing process. For this, a new machine was designed and built, in which it is possible to have a control of the polishing speed, that has better fixation of the discs, more ergonomic, that is portable and that allows to carry out a metallographic preparation of samples that comply with the requirements of ASTM E-3-01.
