Estandarización de los procesos para el mecanizado de los cilindros en los tornos 300 y 450 del taller de cilindros de laminación en la empresa Acerías Paz del Rio

Abstract

A diagnosis was made of the operation of the lathes 300 and 450 of the Rolling mil workshop of the Company Acerías Paz del Rio, to determine the inconsistencies that appeared when machining or rectifying cylinders and subsequently correcting them, a checklist for lathes, in order to guarantee important safety protocols before operating. During the diagnosis made it was evident that the operators repaired the cylinders empirically, causing damage to the equipment, the operational pattern “lathe operation 300 and 450” was designed, a document that expresses the best practice to perform a job, with the purpose of optimize and technify the machining or grinding processes. Cylinder workshop operators are trained to accept the operational pattern.

The process sheet was designed which is a spreadsheet where variables are placed and with the use of formulas we generate results as parameters to configure the lathe with the aim of mitigating damage to the equipment, improving the way in which it operates. Lathes. An evaluation was made of the production índices of the cylinder shop in terms of the operation of the lathes 300 and 450, where predictive maintenance was performed on the lathes, as was the oil analysis and an analysis of the workshop unavailability graphs of cylinders to verify the results obtained.
