Description
Technical field
The present invention relates to a kind of micro-emulsion cutting fluid composition and method of making the same.
Background technology
Cutting fluid is divided into water-insoluble (oil base) liquid and water-soluble (water base) liquid two big classes by the oil product chemical constitution.
The lubricity of oil base cutting fluid is better, and cooling performance is relatively poor.It is relative relatively poor that water-base cutting fluid and oil base cutting fluid are compared lubricity, and cooling performance is better.Cutting requires the oilness of cutting fluid to be eager to excel at a slow speed, in general, uses machining oil when cutting speed is lower than 30m/min.
The machining oil that contains extreme-pressure additive is no matter to the machining of any material, all be effective when cutting speed is no more than 60m/min.When high speed cutting, because thermal value is big, the heat-transfer effect of oil base cutting fluid is poor, can make the temperature of cutting zone too high, cause machining oil to produce smog, phenomenon such as on fire, and because the too high generation thermal distortion of workpiece temperature, influence the workpiece working accuracy, so use water-base cutting fluid more.
Emulsion combines the oilness of oil and the fabulous cooling of rust-preventing characteristic and water, possesses preferably lubricated cooling property simultaneously, thereby the metal cutting of the high velocity, low pressure power that generates for big calorimetric is processed very effective.Compare with the oil base cutting fluid, the advantage of emulsion is bigger thermal diffusivity, and cleaning, dilute with water use and economy of bringing and the health that helps the operator and safety and make that their are glad to use.In fact except that special difficult to machine material, emulsion almost can be used for all machining and most of heavy loading light, moderate duty and process, emulsion also can be used for all ground finishs except that thread grinding, groove fiber crops such as cut at complicated grinding, the shortcoming of emulsion is that sky easily makes bacterium, mold propagates, make effective constituent in the emulsion produce decomposition and smelly, rotten, so generally all should add the little organic bactericide of toxicity.
The advantage of chemosynthesis cutting fluid is economy, rapid heat dissipation, the strong and fabulous workpiece visibility of cleaning, is easy to control finish size, and its stability and anti-corrupt energy force rate emulsion are strong.Oilness is not good enough, and this will cause the adhesion and the wearing and tearing of lathe movable part, and the thick residue that chemosynthesis stays can influence the motion of machine parts, also can make the faying surface of these parts produce corrosion.
The development of cutter material has promoted the development of cutting fluid, invents rapid steel, 2～4 times of the more preceding raisings of cutting speed in 1898.Nineteen twenty-seven, Germany at first developed Wimet, and cutting speed improves 2～5 times again than rapid steel.Along with improving constantly of cutting temperature, the cooling performance of oil base cutting fluid can not satisfy the cutting requirement fully, and at this moment people begin to pay attention to again the advantage of water-base cutting fluid again.Produced oil-in-water emulsion in 1915, and become the cutting fluid of preferentially selecting for use in nineteen twenty and be used for heavy cut.Developed first kind of no oily synthetic cutting fluid in the U.S. in 1948, and impact to make to use and improve owing to oil price in the seventies in 20th century.
In recent ten years, because the improving constantly of cutting technology, the continuing to bring out of advanced cutting machine, the development of cutter and workpiece material has promoted the development of cutting fluid technology.Along with the deep development of advanced manufacturing technology and the reinforcement of people's environmental protection consciousness, the cutting fluid technology has been proposed new requirement, it will promote the cutting fluid technology and develop to higher field.
