Definitions

  • the present invention relates to a neat cutting oil composition and to a process for working metals and metal alloys.
  • Cutting fluids have been used for a long time to perform generally the following functions :
  • Neat cutting fluids are usually preferred when excellent lubrication, good rust protection and surface finish are required.
  • the invention thus provides a neat cutting oil composition which, besides exhibiting low misting and evaporation tendencies, also has excellent cooling properties.
  • the invention provides a neat cutting oil composition
  • a neat cutting oil composition comprising, based on the total weight of the composition, from 10 to 99%, preferably from 70 to 99%, of a hydrogenated dimer or a mixture of hydrogenated dimers, the dimer(s) being selected from the group consisting of octene dimers, decene dimers and dodecene dimers.
  • the invention further provides a process for preparing the neat cutting oil composition.
  • the invention also provides a process for machining metals, comprising applying an effective amount of the neat cutting oil composition of the invention to the metal being machined.
  • the invention provides the use of the neat cutting oil composition of the invention in a metal machining operation.
  • the present inventor has found that hydrogenated octene, decene or dodecene dimers have a low viscosity whilst surprisingly also having low tendencies to evaporate and generate mist.
  • a hydrogenated dimer or a mixture of hydrogenated decene is herein intended, a hydrogenated dimer or a mixture of hydrogenated dimers, respectively, which is/are substantially pure, i.e. at least 90% pure ,preferably at least 95% pure, and more preferably at least 98% pure.
  • Such hydrogenated dimers typically have a viscosity from 5 to 7 cSt at 40°C, preferably from 5 to 6 cSt at 40°C.
  • the preferred dimers are decene dimers.
  • each decene gives a mixture of several decene dimer isomers, which result from rearrangements of one or two methyl groups in the dimer molecule.
  • the preferred decene dimers are hydrogenated 1-decene dimers.
  • These hydrogenated 1-decene dimers can be prepared using sulphated zircona catalyst as described in Sarin, R., Tuli, D.K., Sinharay, S., Rai, M.M., Ghosh, S., and Bhatnagar, A.K., ACS, Div. Petr. Chem. Reprints, 41 (1996) 625.

  • Example of anti-mist agents are high molecular weight polyisobutylenes.
  • the neat cutting oil composition of the invention is prepared by blending the base oil and the other ingredients, preferably under stirring or with any other mixing device and whilst controlling the temperature so that is does not exceed 70°C, and more preferably, 50°C.

  • the cutting oil composition of the invention (Table 1) and the cutting oil composition of the prior art (Table 3) were tested in machining operations, including turning, drilling, tapping, threading, grooving and parting off.
  • the machining performances of an oil composition are reflected by the number of broken tools. The lower the number of broken tools, the higher the performance.
  • the Renault mist test D65 1649 is carried out with the cutting oil composition of the invention and with the cutting oil composition of the prior art, using a device as represented in Figure 3.
  • An air flow is filtered and then flows trough a venturi, sucks the oil up to generate a spray.
  • the spray then reaches a glass cylinder where the oil is partially recondensated.
  • the mist formed is evaluated by weight measurement.
  • the diameters of the particles of the mist generated by the device of Figure 3 from the oil composition of the invention and the oil composition of the prior art are determined using a particle size analyser known under the tradename SPRAYTEC and sold by the company MALVERN.
  • This analyser determines a particle size pattern of oils, using a laser diffraction technique.
  • the particle size is inversely proportional to the angle of diffraction of the incident light.
  • the average particle diameter are found to be 4 ⁇ m for the neat cutting oil composition of Table 1 and 3 ⁇ m for the neat cutting oil composition of Table 3.
