    The research is about the operational processes optimization using the theory of constraints in the metal-mechanical Maquinarias Espín. Initially, delays and bottlenecks were detected in the production of wood processing machines, these aspects forced the extension of the working day. The production of the seven machines with the highest demand was considered, taking into account the information of the average monthly quantity required according to the orders of the last two years. A time study was carried out and the available resources were evaluated to quantify the use of the workstations. Two constraints were identified in hand saw cutting and turning as part of the application of the theory of constraints, with utilization ercentages of 111.82% and 105.11%, which implied an inability to meet the average monthly demand. From exploiting the constraints based on the application of the PLE to maximize the return and once everything was subordinated to them, the maximum possible monthly return was determined to be $78470, with a maximum net profit of $68362.68. However, the maximized production volume did not meet the average monthly demand, with a shortfall of 5% of circular saws and 75% of band saws. A CNC plasma cutting machine was added as well as the distribution of workers at the workstations was rearranged. It was determined that there were no longer any constraints once the actions were implemented, but the PLE was again applied to optimize production based on the available resources. These actions allowed obtaining a maximum yield of $ 87768.74, with an optimal monthly gross profit of $ 77188.10, an increase of 12.91% of the gross profit from the sale of the machines, having covered the production capacity required by the demand.
