Lubrication of Metal Working Operations & Machine Tools

  • Engineers and technical staff involved in the development, recommendations, use, maintenance and follow up of the fluids (essentially cutting, rolling, thermal treatment) and the lubrication of machine tools, as well as the solving of operating issues.
  • To bring the necessary technical information on metal removal operation and plastic deformation to the non-specialized people for a better understanding of the role of the lubricant; to bring technical knowledge of the different types of products (functional properties, chemical composition, characterization methods); to provide an overview of the problems raised by the products in use, from their introduction in use to their withdrawal, including the hygiene, toxicity and environmental aspects.
Learning Objectives
  • To describe the different machines used for metal removal and rolling.
  • To describe the different metal working operations.
  • To describe the different types of fluids for metal working and thermal treatment.
  • To give the necessary information for introducing the fluids in use, their follow up and their withdrawal.
  • To solve the possible in-service issues.
  • To give the necessary information of the toxicity, hygiene and environmental aspects.
Ways and means
  • Interactive exercises with the teacher to determine the lubricant to use depending on the type of organ and the operating conditions.
  • Interactive exercises of questions-answers between the participants using sets of play cards to synthetize the essential points of the lectures.
