Background technology
Continually developing and applying along with new metallic material and complete processing, the heavy loading processing application in metal-processing industry of some difficult-to-machine materials as metallic substance such as extraordinary die steel, stainless steel, high-temperature alloy steel, titanium alloy, nickelalloys gets more and more.The heavy loading processing of difficult-to-machine material, as fraising, boring, tapping, tapping, broaching and screw thread process etc. in the course of processing due to features such as material hardness are high, yield strength is large, thermohardening is obvious, difficulty of processing is large, cause producing between cutter and workpiece in working angles very large friction and heat (temperature can up to 1000 DEG C), also can cause damage to cutter and equipment.Therefore, add man-hour in the heavy loading of difficult-to-machine material, select a cutting fluid having better oilness, cooling, rust-preventing characteristic and cleaning concurrently, to the precision of converted products and cutter life, there is important effect.
Cutting fluid is divided into water-insoluble (oil base) cutting fluid and the large class of water-soluble (water base) cutting fluid two according to composition and medium state, and water-soluble metalworking liquid is divided into again emulsion, microemulsion and synthesis liquid.Oil base cutting fluid has oilness and the good advantage of rust-preventing characteristic, but cooling and cleaning poor, the mist of oil produced in use procedure is larger, big for environment pollution, and have the danger of potential fire, in recent years along with the shortage of petroleum resources and constantly rising violently of oil price, its use is subject to certain restrictions; Emulsion and microemulsion form primarily of mineral oil, water and emulsifying agent, be characterized in oilness and rust-preventing characteristic better, but poor in cooling, perviousness, stability in storage and biologically stable, easy to be smelly rotten, work-ing life is shorter, and there is environmental issue during discharge; Fully synthetic cutting fluid is primarily of water and various water-soluble additive (as soluble oil, extreme pressure agent, rust-preventive agent, tensio-active agent etc.) composition, there is excellent cooling, cleaning and stability in storage, owing to not containing mineral oil, having positive meaning from aspects such as environmental protection, saving petroleum resources, is the direction of cutting fluid development.But, in domestic prior art, fully synthetic cutting fluid is not at oilness, rust-preventing characteristic, also have ideal result of use in work-ing life, be mainly used in the light load processing occasions such as grinding, during the heavy loading of metal-working industry difficult-to-machine material is processed at home, the application of fully synthetic cutting fluid does not also have larger breakthrough.
In addition, in domestic prior art, fully synthetic cutting fluid uses boric acid, Sodium Nitrite and secondary amine as antirust, anticorrosive agent in a large number.Europe has forced have the material of potential hazard to carry out label to some, and boric acid is wherein a kind of material.Boric acid likely makes the mankind sterile and has harm to unborn child; Boric acid, once be dissolved in water, is difficult in the treatment of waste water remove thus affect environment, works the mischief to the mankind.Sodium Nitrite and secondary amine reaction generate the nitrosamine having carcinogenic danger, and Europe has forbidden using Sodium Nitrite and secondary amine in cutting fluid.
