  • Formulations of soluble type metal working oils are quite complex. These oils in general constitute an area of lubrication technology where chemistry is very much in action in the whole application regime.

Unlike other industrial oil lubricants, where the performance of the oil will be known only after some time, the performance of soluble type metalworking oil will be known as soon as it is put into the machining operation. A defect in a soluble oil, for example cutting oil or rolling oil, will show up immediately after starting operation or at the most in a couple of days and will call for quick corrective action. The factors affecting the performance of these oils are multi faceted; therefore, these oils require special attention of the formulator as well as user. Performance of the same oil may vary significantly from one user to other depending upon the nature of application, metallurgy and maintenance practices followed by the user. Water quality significantly contributes towards performance of the oil.

L'invention porte sur une composition d'huile de coupe soluble, très efficace, semi-synthétique, biologiquement stable et non dangereuse pour l'utilisateur, pour des applications de travail des métaux, qui comporte une huile à broche d'indice de viscosité élevé, une amine, un acide gras, un ester, un biocide, un co-solvant, un inhibiteur de corrosion, des émulsifiants et de l'eau. La composition de l'invention forme une émulsion laiteuse avec de l'eau et elle peut être employée pour des opérations de travail des métaux comme le coupage. La composition de l'invention est particulièrement appropriée pour des opérations de fraisage, de perçage et de tournage dans des machines commandées par ordinateur CNC automatique, ainsi que dans des opérations d'usinage manuel. La composition présente d'excellentes caractéristiques en termes de stabilité biologique et de refroidissement, ainsi que de très bonnes propriétés de protection contre la corrosion, même avec de l'eau calcaire et de l'eau ayant une teneur élevée en chlorure, conjointement avec une très bonne stabilité d'émulsion. La composition est exempte d'additifs au chlore, au bore, au phosphore-soufre actif qui ne sont pas considérés comme étant écologiques, ni non dangereux pour l'opérateur. La composition est appropriée pour l'usinage de métaux ferreux et non ferreux comme l'aluminium, etc.
