In metallic cutting and metallic treatment company, use cooling fluid is a very general issue. But it also brought particular issue to industrial business, contaminant of the environmental protection duty that if the machine tool cools,the charge of lubricant equipment can amount to a machine tool to purchased the hundred; of investment to increase an enterprise to want turn over to the higher authorities, industry and blowdown charge. These raised the additional cost of machine tool equipment. If cooling fluid is handled undeserved, still can increase environmental pollution, damage person health. Accordingly, in last few years, the cry that hopes to use refrigeration doing type to lubricate and desire are stronger and stronger. But up to now, while lubricant technology is raising cutting to machine exterior quality, various refrigeration doing type improve the service life of cutting tool. And the optimal solution that replaces refrigeration doing type to lubricate is minimum cooling and lubricant, abbreviation MMKS. Air / oil fuses the technology that refrigeration uses air and lube eject this kind to be nodded to cooling action is very reliable in numerous cooling method of lubrication with what have conviction. This one technology in the milling in steel of cementite of alloy of aluminium alloy, nonferrous metal, low alloy and tool steel and turning treatment received successful application. Company of Oelheld of cooling fluid manufacturer participated in much research and project development, so that mining MMKS minimum is cooling and lubricant bigger application field. The project of research and development that they join, among them one is to use the least cooling technology to replace a large number of cooling stainless steel to get cut technical project, and stainless steel is a kind special hard the metallic stuff of cutting. The material of X90CrMoV18 stainless steel of tall to this kind alloy (contain chromium 18% , molybdenum 1.

3% , vanadium 0.

12%) , minimum is cooling and lubricant technical use is a demand is very high really tackle key problem project. This kind of tall alloy steel is having very good corrosion resistance can, suit to make tall wearability part, if scroll bearing perhaps makes the material of surgical operation appliance. When processing data of this kind of metal, get those who cut treatment generation, conducting the quantity of heat that is in to orifice acute angle is a difficult problem that must solve. Cooling inadequacy can make get cut cutting tool very fast wear away, plasticity of generation of broach cutting blade is out of shape will make its lose cutting ability finally. Normally the circumstance falls, minimum is cooling and lubricant cooling and lubricant material of the system is mix with mineral oil, lubricant ester synthetic oil is made for basic material. And cooling and lubricant material is in the minimum that material of this kind of foundation makes minimum is cooling and lubricant medium effect is unidentified however show, although use different additive also the durability of the cutting tool when short of large flow is cooling and lubricant. When processing this kind of data, because refrigeration is lubricant the inadequacy of the quantity is aggravating still the form of collect bits tumour is unripe, and because cut the temperature of bits,mix higher be out of shape relatively the ambassador must break bits function to become poor. Accordingly, the broach that is necessary to be used to place is mixed in its geometry appearance, dimension, base material the respect such as exterior coating material undertakes optimizing improvement. The optimal effect of durability of broach cutting tool is to pass data of use TiAlN/MoS2 coating, the broach of microcrystalline hard alloy that combines microcosmic geometry dimension to improve will come true. Optimized building blocks type is lubricant the system lubricates to find the most appropriate minimum to cool material, the researcher of Oelheld company used system of reliable research and development of product of building blocks formula. Namely, undertake optimizing through active additive above all. For this, engineers of research and development according to 5 kinds of basic active additive group did not develop the work: Wear away defend additive (AW) : Through wearing away with what fight coating of metabolic metal surface to material reacts and avoid cutting tool. Be able to bear or endure high-pressured additive material (EP) : Reduce below high pressure and high temperature cutting tool and by cutting metal surface between microcosmic wear away. The additive that reduces coefficient of friction (FM) : Reduce a metal to contact exterior coefficient of friction each other, reduce thermic load. Oxidation depressor: Prevent cooling lubricating fluid because of oxidation solidify and material of acidification of deoxygenate polarization form. Antiseptic: Prevent acid and oxygen through the diaphragm that forms in metallic surface invade, form waterproof layer to perhaps be in the cooling and lubricant system of water-solubility make cost of basic acid-base value PH. Finally, engineers of research and development chose the organic salt of water-solubility to be a foundation. Its higher water content is very important, a series of tests that had had prove: The additive in water makes dosage less, more advantageous to the wear-resisting function of cutting tool. Right now, can saying was to truly the minimum refrigeration that applies to stainless steel material lubricates. After the moisture in cooling fluid evaporates, reservation is in of cutting tool surface is adherent force is very powerful, the saline sex that is helpful for reducing attrition is filmy. The personnel of research and development of Oelheld company returned the function of solution of organic to this kind salt to undertake farther improvement. Was to join AW to fight above all wear away repellent, joined EP to be able to bear or endure again after that high-pressured additive. So far, the durability photograph of broach of the stainless steel when with large flow refrigeration lubricates is compared, the cutting tool life when minimum is cooling and lubricant rose 60% . The optimal refrigeration that improves cutting tool service life is lubricant, also can use minimum refrigeration to lubricate when processing tall alloy steel. CNC Milling CNC Machining
