Introduction
⌅The adequate management of maintenance process ensure to fulfill the social object of enterprises; it constitute a fundamental factors to guarantee that the repairing cost could be reduce with no affect product quality nor equipment’s availability.
Maintenance lubrication management allow guaranty reduction on friction and surface wear, lubrication failures, diminish energy consumption and no affect workers security. Actually is complete secure the Jost Institute study done, that estimated that losses due to no efficient lubrication management constitute 1, 60 % of world internal gross product (Deus et al., 2022DEUS, A.C.; GARCÍA, T.A.; ALFONSO, P.Y.; MIRANDA, A.M.A.; VARELA CANCINO, C.J.: “Diagnóstico del estado de la Gestión de Lubricación en Grupos Electrógenos Fuel Oil”, Ingeniería Energética, 43(2): 1-9, 2022, ISSN: 1815-5901.; García et al., 2023GARCÍA, T.A.E.; PENABAD, S.L.; DEUS, A.C.; BARRERA, R.C.; GUILLÉN, G.J.: “Modelo para la gestión de la lubricación y los lubricantes en la industria”, Ingeniería Mecánica, 26(3): 45-53, 2023, ISSN: 1815-5944.).
The cost of lubrication is 3% the one of maintenance activity and the 80% of that are due to inefficient lubrication. This is most important on pharmaceutical enterprises which products are higher and complex, sometimes export products.
Nowadays science, technology and innovation are very important for the Social Economy Development (PCC, 2016PCC: Lineamientos de la política económica y social del partido y la revolución para el período 2016-2021, Inst. Comité Central del PCC, La Habana, Cuba, 2016.). Also it is very important to consider maintenance active as an inversion and not as expenses (Mora, 2006MORA, G.A.: Mantenimiento Estratégico para Empresas Industriales o de Servicios, La Habana, Cuba, 154 p., 2006, ISBN: 958-33-828-3.). CEIM research the good practices on lubrication on different development countries in different enterprises and on different national enterprises (Díaz, 2011DÍAZ, Y.M.L., C.L.: “Indicadores para el ahorro de los portadores energéticos en la Empresa Eléctrica de Pinar del Río en función del desarrollo sostenible”, Revista Científica Avances, 13(3), 2011, ISSN: 1562-3297.; Rodríguez, 2017RODRÍGUEZ, J.L.F.: Procedimiento para la evaluación del impacto de la introducción de una nueva tecnología de lubricación en la UEB Lisa, Centro de Estudios e Ingeniería de Mantenimiento, Universidad Tecnológica de La Habana (CUJAE), Tesis presentada en opción al título de Ingeniero Mecánico, Marianao, la Habana, Cuba, 2017.). That’s why BIOCUBAFARMA enterprises was interested to adopt convenient strategies to guaranty its organizational exit.

⌅Theoretical fundament
⌅Methodology
⌅Lubricants
⌅Lubricants are substances that diminish friction on machine parts or on relative machinery movement. Lubricant is a third body on wear; not also reduce friction a wear but also facilitate heat transference that is generated on friction and allow wear particles movement that are generated. It is necessary that the third body had a low tangential stress movement opposition between parts on wear. Lubricants can be gaseous, liquid or solids (Marais et al., 2013MARAIS, K.B.; RIVAS, J.; TETZLOFF, I.J.; CROSSLEY, W.A.: “Modeling the impact of maintenance on naval fleet total ownership cost”, En: 2013 IEEE International Systems Conference (SysCon), Ed. IEEE, pp. 801-808, 2013, ISBN: 1-4673-3108-2.; Rodríguez, 2021RODRÍGUEZ, M.D.: “Evaluación de la gestión ambiental de la Empresa Cubana de Lubricantes, Santiago de Cuba”, Anuario Facultad de Ciencias Económicas y Empresariales, 12: 208-231, 2021, ISSN: 2218-3639.)
Additives are organic and inorganic components dissolve on base lubricants which function is to give new properties to basic lubricant, increase those properties or avoid not desirable’s properties. Lubricants are chosen in accordance to desirable missions, in accordance to surface type, charge, temperature, lubrication system and substances in contact with the lubricant.
Lubrication
⌅Lubrication is an essential aspect on maintenance to allow efficient functioning. It is very important to reduce costs, to increase useful life and an efficient production (Balliache, 2015BALLIACHE, D.: El problema y su delimitación, [en línea], Ed. Academia.edu, D Balliache ed., España, 2015, Disponible en:https://prezi.com/gxhx3tvyygq4/el-problema-y-su-delimitacion.; Martínez, 2017MARTÍNEZ, P.F.: Mantenimiento Industrial. Conceptos y Aplicaciones, Ed. Editora Minaz, Cuba, La Habana, Cuba, publisher: Editora Minaz, Cuba, 2017.; Hernández, 2020HERNÁNDEZ, S.R.: Metodología de la investigación: las rutas cuantitativa, cualitativa y mixta, Ed. Mcgraw-hill México, México D. F., publisher: Mcgraw-hill México, 2020.).
When there are failures on lubrication, metals and other materials could be destroying, causing no repairable damages and materials, heat (Salazar et al., 2015SALAZAR, P.D.; BAIZABAL, F.G.; LÓPEZ, V.A.; FRANCO, A.L.; SÁNCHEZ, E.J.A.; GONZÁLEZ, G.L.; TORRES, H.J.: “El ciclo de evolución de los lubricantes”, ContactoS, 97: 62-68, 2015.). Efficient lubrication is the one that where it is applied an adequate lubricant, when are done or necessaries actions (require quantities of lubricant, adequate and prepare workers) (Chávez, 2014CHÁVEZ, V.A.: Evaluación de la Gestión de Lubricación en el Taller de Forja de la UEB Vanguardia Socialista, Universidad Tecnológica de La Habana (CUJAE), Tesis presentada en opción al título de Ingeniero Mecánico, La Habana, Cuba, 2014.).
Lubricant and lubrication management
⌅Management of lubrication activities is a complex process. Very important are the use of modern technologies on lubricants selection, application and analysis (Ramírez, 2012RAMÍREZ, C.L.C.G.T.: “Estudio de la Actividad de Lubricación para formular una propuesta de Gestión por Procesos”, En: Convención Científica de Ingeniería y Arquitectura, Palacio de las Convenciones de La Habana. 26 al 30 de noviembre, 2012., 2012.). All these is the guaranty of equipment availability.
Sometimes it happens that are not obtain good results on lubricants weariness and that Is not due that was bought a bad quality lubricant, but because was not done a good application and the conditions of technological equipment. (Gamez, 2015GAMEZ, M.R.B.: Diseño de herramienta para la evaluación de la gestión de la lubricación y los lubricantes, Universidad Tecnológica de La Habana (CUJAE), Centro de Estudios en Ingeniería de Mantenimiento, Tesis presentada en opción al título de Ingeniero Mecánico, La Habana, Cuba, 2015.).
Development studies realized by different companies of the world that had been evaluated by STLE (Engineers and Tribology’s on Lubrication) established that more than 50% of wear of rollers are caused by inefficient lubrication and 80% of wear is caused by contamination of lubricants and that 30% of lubricants are replaced when is possible to continue their work (Torriente, 2016TORRIENTE, C.R.A.: Diagnóstico de la gestión de lubricación y lubricantes en la UEB Santa Amalia de la Empresa Provincial de Transporte de La Habana, Universidad Tecnológica de La Habana (CUJAE), Tesis presentada en opción al título de Ingeniero Mecánico, La Habana, Cuba, 2016.).
Characteristics of lubricants and lubrication on pharmaceuticals enterprises
⌅On pharmaceutical enterprises lubrication have a specific characteristic because systems could not contaminate the used prime materials on medicaments production and because failures on actives due to failures on lubrication affect quality of final product and production plan. Different machinery employ in pharmaceutical require periodical lubrication such as colloidal mill, pressed for tablets and the mixer-granulator. On sterile ambient, lubricants could be source of microbial contamination and is a risk for quality and efficiency.
Taking that on account it is only allow the use of lubricants capable for the contact with foods and has to be certified by 1SO 21469. Fabricants had to be registered by National Sanitation Foundation (NSF) H1. This category is one of the three existed in lubricants, besides are used lubricants classified H2 to work on parts no exposed to product. ISO 21469 require that lubricants producers developed hygiene strategy for chemist, physical and biologic risk in context of the use of lubricants.
Employed weapons on research
⌅Management maintenance process has important and powerful weapons for research that help to decide actions to take in the presence of different situations that help to maintenance personal.
Selection of the group of experts
⌅Most analysis and comparison tools require the criteria of “experts” to be fully developed. Given the use of these tools in research, it is necessary to select a group of experts to argue them.
This method allows consulting a set of experts to validate the proposal based on their knowledge, research, experience, bibliographic studies, etc. (Hurtado, 2012HURTADO, S.: “Criterio de expertos. Su procesamiento a través del método Delphi. Histodidáctica, web de la Universitat de Barcelona”, 2012, Disponible en:http://www.ub.edu/histodidactica/index.php.; Cabrero, 2014CABRERO, A.J.I.M.: “Empleo del método delphi y su empleo en la investigación en comunicación y educación”, EDUTEC. Revista Electrónica de Tecnología Educativa, 48: 16, 2014.)
The level of competence of the experts is evaluated by the competence coefficient (K), which is calculated according to established rules; which were fulfilled in the present research. (Martínez, 2017MARTÍNEZ, P.F.: Mantenimiento Industrial. Conceptos y Aplicaciones, Ed. Editora Minaz, Cuba, La Habana, Cuba, publisher: Editora Minaz, Cuba, 2017.).
Tools for the evaluation of lubrication and lubricant management
⌅The tool to diagnose lubrication and lubricant management used in the research was the one designed and validated by professors from the Center for Maintenance Engineering Studies (CEIM). It is a tool that, unlike other similar ones, allows a natural work team of the organization to self-assess the management of lubrication and lubricants with a concurrent approach using inspection and diagnostic technologies in an integrated manner, which contributes to continuous improvement. It is a tool that allows all aspects of lubrication management, lubricants and human resources associated with it to be addressed in an organized and thorough manner. The tool makes it possible to locate the sectors with the greatest potential for change, which makes it easier to carry out a comparative analysis after its successive application, which shows the trends of change and constitutes the basis for continuous improvement.
Characterization of the current maintenance situation
⌅The maintenance activity is carried out by the Maintenance Group subordinate to the non-functional Engineering Department, the latter answering directly to the General Manager.
The maintenance carried out is planned preventive (MPP) and, to a greater extent, reactive, with the former not reaching the desired effectiveness, resulting in the need for large inventories of resources in the warehouses to be able to carry out the interventions. Although the maintenance staff has some diagnostic equipment, it is not used, so condition-based maintenance is non-existent.
The maintenance process is not certified and is considered support within the Integrated Quality Management System.
The production plants have a maintenance specialist who focuses on the activity with the support of a mechanic and an electrician. The lubrication activity is carried out in a shared manner, the part of the equipment that has direct contact with the product is lubricated by the operator and the part considered dirty or that has no contact with the raw material and the packaging material is carried out by the mechanic.
The lubricant used is purchased partly from the equipment manufacturer and the other part from Cuba Lub, with the Marketing Department taking charge of the logistics.
The maintenance activity does not have the staff covered nor the human capital fully trained to satisfactorily carry out the tasks inherent to the process.
98% of the electrical and electronic components and 90% of the spare parts used are imported due to the impossibility of manufacturing or purchasing them in our country due to the characteristics of the equipment, a situation that causes delays in maintenance plans and is one of the causes of unforeseen breakdowns and failures.
Outsourcing, in the case of maintenance, has a great impact since, for the most part, it is carried out by foreign companies
Their control systems are considered complex, so they must have high availability since any failure or breakage implies a loss of raw material and packaging material, as well as the consequent environmental and human risks.
Due to technological costs, the basic equipment is unique (Preparation, Encapsulation, Filling, Microdosing and Cross-Body) and when it fails, it stops the entire technological flow; therefore, it requires high operational safety since it is the one that fundamentally causes contamination and affects workers, which is why they are exposed to rigorous controls.
Tool for assessing lubrication and lubricant management
⌅The tool for diagnosing lubrication and lubricant management used in the research was designed and validated by professors at the Center for Maintenance Engineering Studies (CEIM).
