% mixes photograph of fluid of cutting of get along with 5 minutes, do not have of slideway oily photograph 6 minutes not statified, it is to mix to mix slideway oil and cutting juice with each scale of 50% again entirely, the cutting fluid photograph after extraction mixes 24 hours (draw mixture look without cutting fluid photograph) , represent the difference that its numerical value and fresh cutting fluid are worth accordingly with NV, judge standard is as follows: of factor project of of of 0 minutes of of of of of 1 minute of 0% of ≤ of NV of of of of of 2 minutes of chroma 10% machining center are undertaking when wet cutting, cutting fluid dosage often is as high as 20~100L/min. MQL technology should be used only proper, the cutting tool after treatment, workpiece and cutting bits is dry, this avoided the processing of later period, after the clean and clean classics that cut bits is compressed, still can reclaim use, do not pollute an environment completely, friend says again do type cutting to allow. Current, the treatment object of lubricant technology basically uses minim cutting at be on cast-iron, steel and aluminium alloy to undertake curiuming cutting, mill face and the CNC Machining of all sorts of accurate industries. American ACCU-LUBE company can be offerred apply at of all kinds metal treatment uses plant cutting oil and the drop that do type cutting to use definitely lubricant system. Graph 4: Mill is machined in last few years, germany is lubricant to minim cutting year of demand of device is annual be in 15, 000 fluctuate, and field of this one still will expand further. Visible, minim cutting lubricates to be used with the union of new-style cutting tool in the ascendant. Predict to be in future inside 3 years two, the technology that the machining center lieutenant general that Germany creates has 5% meetings to use minim cutting to lubricate to be united in wedlock with photograph of lubricity coating cutting tool, erode in order to replace style is cool. Elegant be an official of Japan amounts to a company to already will lubricate the system is compositive in main shaft, its discharge is controlled by CNC process, this unit is in 6.
Can get inside the time of 5s cut 10 diameters 8mm, center to be apart from the aperture that is 20mm, use a cup of lubricating oil hourly, and be evaporated for the most part, the cutting juice content in cutting bits is reduced significantly, also saved relevant processing cost considerably thereby. In a lot of metal treatment, lubricant is medium additive, microbial with other component pulverization hind as much likelihood by handlers inside inspiratory body, endanger respiratory system, digestion thereby, cause cancer possibly even. In addition, oily mist still can form a bur in workshop upside, bring a trouble to daily attention. Accordingly, the air oily mist that to different treatment methodological place causes is atomic chroma develops research, very necessary. Look from environmental protection angle, traditional and pouring chroma of oily mist particle is different in the air that lubricant place creates law and minim cutting. American Cicinati university and Techsolve.
Inc company develops research jointly, the chroma of particle of air oily mist that to minim cutting lubricates and eroding type cutting leaves generation has comparative test, mix with 11ml/min respectively on machining center of Tongil TNV-80CNC vertical 6.
The dosage of 5l/min is right AISI/SAE 4340 steel undertook getting cutting mixing milling. The result makes clear, fall in inferior cutting speed and metallic excision rate, in getting the air that lubricant law creates cutting of the minim when cutting, oily mist particle is generated rate (the atomic quantity of minutely generation) it is traditional and pouring the 340~3300 of the law times; Its 100~140 is when milling times. Below higher rate and metallic excision rate, this specific value will be greater. Minim cutting is lubricant can decrease considerably " cutting tool - workpiece " and " cutting tool - cut bits " the attrition between, restrain temperature rise, reduce cutting tool to wear away, prevent adhesion and improve workpiece to machine quality, improving work efficiency while the pollution that reduced pair of environments again. And, the photograph is more pouring than the tradition cutting means, minim cutting lubricates to still can reduce the dosage of cutting fluid apparently, avoided the processing of waste liquid, reduced finished cost (include cutting juice buy fare, store charge and fee of waste liquid processing) , and can obtain below certain condition equal better even treatment performance. The grinding oily DIAGRIND 535/15 that 〔 Shanghai still offers Ou Hai company of oily Germany of grinding of DIAGRIND 535/15 of draft 〕 Ou Hai into limited company, used on raw material compare advanced synthesis base oil at present: Hydrogenation splitting decomposition is oily. With normally mineral oil kind product photograph is compared, this base oil does not contain any not saturated hydrocarbon and balmy hydrocarbon compound, these material make a product very flabby not only calm and easy ageing, what still can endanger relevant personnel is healthy. In the meantime, DIAGRIND 535/15 contains the additive of 25~30% , include to be able to bear or endure among them extremely pressure lubricant and additive, improved agent, fight grind additive, antioxidant and fight 30 kinds of raw material such as vaporization agent, all-around ensured the processability of the product can be mixed service life. From service life this angle looks, mineral oil kind the life of the product makes an appointment with 1 year, DIAGRIND 535 need not change inside below normal use circumstance 3 years, need to be added normally only. After 3 years, europe sea respect will offer free product every year to detect, use in order to decide whether the product can continue. According to the experience of company of German Europe sea, the real service life of this product (experience is worth) it is 5 years about. Measure a respect as to loss, compare mineral oil kind the product, DIAGRIND 535 has lower viscosity below the flash point of close (viscosity is mineral oil only kind product in part) . Its are machining reason the amount that oil of the grinding in the process is taken away by workpiece very few, relatively mineral oil kind the loss of the product measures a bring down make an appointment with 20~30% . Be worth what carry is, because oil of hydrogenation splitting decomposition has quite tall purity and stability, make the viscosity of DIAGRIND 535 not easy the influence that is fluctuated by temperature, this ensured treatment process can be below a very stable condition undertake, ensure product quality is consistent. And, the purity of oil of splitting decomposition of profit from hydrogen sulfide and stability, grinding oil won't corrode the exterior coating inside the machine tool, plastic conduit, balata with weather strip. Although be on the price, DIAGRIND 535/15 tower above is general mineral oil kind the product makes an appointment with one times, but in view of its lower wastage (reduce 20~30% ) with longer service life (delay to 2~3 times) , synthesis of its put together compares mineral oil originally kind the product is low piece make an appointment with 30~50% (not plan the loss that enters treatment efficiency, emery wheel, and the charge that change and processes oil to taste) , show relatively the sexual price of actor is compared.
