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, has satisfactory cooling properties.
  • the invention provides 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 white mineral oil.
  • 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.
  • white mineral oil it is herein intended very highly refined oils which consist entirely of saturated components, all aromatics having generally been removed by treatment with fuming sulphuric acid or by selective hydrogenation. Their name reflects the fact that they are virtually colourless and the most highly refined medicinal white oils are used in medical products and in the food industry.
  • the white mineral oils used in the invention are preferably those which can be safely used as a component of nonfood articles intended for use in contact with food. These oils are described in 21 CFR Ch. 1 ⁇ 178.3620 (a) and (b) of the Food and Drug Administration, HHS.
  • White oils are for example sold by the company SIP Limited of LONDON.
  • the white mineral oils typically have a viscosity from 3 to 500, preferably from 4 to 30 cSt at 40°C.
  • the cutting oil composition of the invention comprises a combination of a fatty acid ester with a phosphoric acid ester. This combination provides in flute grinding operations :
  • a fatty acid ester is a fatty acid ester based on triglycerides and containing approximately 10 wt % sulfur including less than 1 wt % active sulfur.
  • the phosphoric acid ester is preferably amine neutralized and contains approximately 95 wt % phosphorus and 3.8 wt % nitrogen.
  • the cutting oil composition of the invention comprises a combination of oleic acid and tri-octyl phosphate. This combination provides in ball bearing grinding an excellent surface finish and extended wheel life.
  • the cutting oil composition of the invention comprises a combination of sulfurized sunflower oil, tri-octyl phosphate and oleic acid. This combination provides an extremely fine finish in the honing of steel bore holes and shafts.
  • the neat cutting oil composition of the invention may comprise conventional additives, such as lubricity agents, antioxidants, extreme-pressure and anti-wear agents, anti-mist agents.
  • lubricity agents are long chain polar molecules, like fats, fatty acids, vegetable oils and esters.
  • extreme-pressure and anti-wear agents are sulphur and sulphur organic compounds, phosphorus organic compounds, or chlorine organic compounds.
  • Examples of phosphorus organic compounds include dilauryl phosphate, didodecyl phosphite, trialkylphosphate such as tri(2-ethylhexyl)phosphate, tricresylphosphate (TCP), zinc dialkyl(or diaryl)dithiophosphates (ZDDP), phospho-sulphurized fatty oils, tricresylphosphate (TCP), trixylylphosphate (TXP), dilauryl phosphate, amine phosphates, phosphoric acid esters.

  • anti-oxidants are metals deactivators like triazole derivatives, chain breakers like phenols, cresols derivatives, peroxyde decomposers like zinc dithiophosphates, metal dithio carbamates.
  • 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 mixing device and whilst controlling the temperature so that it does not exceed 70°C, and more preferably, 50°C.
  • the neat cutting oil composition of the invention can be used in various machining operations like internal, surface or external broaching, tapping, threading, honing, gear cutting, gear shaving, gear hobbing, gear generating, reaming, automatic works, milling, form turning, planing, parting off, drilling, boring, sawing or superfinishing.
  • the neat cutting oil of the invention is particularly adapted in machining operations like honing, superfinishing, bearing grinding, gear grinding or flute grinding.
  • a great number of metals can be machined with the oil composition of the invention.
  • metals include titanium alloys, nickel alloys like Nimonics TM, stainless steel like inconel, tool steel, high alloy steel, high carbon steel, mild steel, wrought iron, silicon aluminium alloys, cast iron, copper, copper alloys, bronze, brass, aluminium and aluminium alloys.
  • Compositions 1 to 3 are prepared by mixing the ingredients of Table 1 in the order in which they appear in this table. The temperature is maintained at a maximum of 50°C to ensure a complete dissolution and homogeneisation of the ingredients without impairing the properties of the cutting oil.
