The use of cutting fluid, management defends with what the machine tool corrodes

1% ～ 0.

Of 3% 3 get together phosphoric acid natrium or 2 ethylamine natrium of 4 acetic acid, can rise to reduce the effect of water quality hardness, had better make use ionic water. Attenuant: The dilute of cutting fluid matters to the stability of emulsion. Before cutting fluid is being used, should decide attenuant scale and the bulk that need emulsion first. Next cipher out place uses emulsion (former fluid) quantity and water quantity. Operation method is: Select clean recipient, all water that wants place pours person container inside, add person emulsion below low speed agitate next former fluid. When making up emulsion, the speed adding a person of former fluid with appearing not emulsification former fluid is accurate. Special attention: The program adding a person of emulsion former fluid and water cannot put upside down, do not want the oily pool in the machine tool (groove) inside allocate a latex directly. In be operated actually, optional sex is very big when we often see the worker is making up emulsion, handlers sees fluid of the cutting inside cistern adds water less, add condense fluid, agitate hind feels cutting fluid is not quite white, add again condense fluid; Look too thick add water again again, everything is given priority to with the feeling. Think of what scale, go almost, the result that it creates is today making up scale is 1:20, tomorrow perhaps is 1:30, this is sure can serious to cutting fluid generation effect. Water-solubility cutting fluid is using a process actually in, the requirement that different treatment form slips to gully and cools is different. Common law is cutting bear bigger, lubricant demand is higher, criterion cutting fluid makes up chroma to be jumped over relatively big; Treatment rate is opposite higher cooling requirement lay particular stress on a few, cutting fluid makes up chroma relatively a few lower. Is usually the metabolic rule of cutting bear: ? Broaching of < of milling of < of ハ ? turning. And machine speed criterion as it happens contrary. 2 because cutting fluid use environment is open mode,use continuously, and composition of general cutting fluid composition fights bacterium function finite, mix to outside bacterium so invaded person and breed microbially to create a condition. Because cutting fluid is medium,growth bacterial majority is bacterium of oxygen of be disgusted with, so cutting fluid stops for long machine need not meet form the anoxic environment that is helpful for a bacterium growing, and use the oxygen that makes air medium to be able to fill dispenses cutting fluid to contact continuously, restrained bacterial growth on certain level thereby. Reason cutting fluid is used " do not be afraid of move be afraid of static " , so machine down time does not exceed 3 days. The maintenance of the clean emulsion of 3 emulsion manages have two sides, it is prevent outside contaminant mix support of the people to keep clear of in time, is another the function stability: that maintains water-solubility job fluid? Min ǘ takes the value of H of  of bath of ⒎ fellow Wu, ability that fight bacterium to wait. Although product of general cutting liquid has the certain capacity that fight bacterium, but because certain part is bacterium and microbial nutrient, below the circumstance that is not worth in the ability that fight bacterium so, the service life of cutting fluid is finite. All sorts of sundry the germ that often is cutting fluid corruption. For example: Butt, boiled water, bombazine sundry and optional discard within birdbath, polluted cutting fluid, became bacterium and microbial the carrier that grow and breeds and nutrient, must control strictly so do not let outside eyewinker confuse a person, once mix,the person must clear instantly. Below the condition that confuses a person basically without outside eyewinker, the material that pollutes cutting fluid basically is fine pink of metallic powder and grit, float oil and free water, microbial wait a moment with progenitive content. Float oil is to show machine tool drive and hydraulic pressure system use the oil of system of fluid of cutting of person of oily because the machine tool is sealed lax leakage. The harm of float oil is to make the certain material of cutting fluid system expands be out of shape, disturbed the emulsification balance of emulsion, make emulsion loses stability. And float oily Chang Fu at latex oily surface layer, held back emulsion and airy contact, bring about emulsion anoxic, make bacterium of oxygen of be disgusted with breeds quickly, quicken the putrefaction of emulsion. The 4 fluid that cut analyse are used ask bowel and countermeasure are become mediumly emulsion by ivory become dust-colour, when corrupt bad smell happens, answer to add antiseptic to exterminate bacterium instantly, or change afresh emulsion. At present more commonly used low poisonous antiseptic is 3 red oil, add a capacity about 0.

1% ～ 0.

2%(is right the emulsion) after dilute, have apparent effect to lengthening the use cycle of emulsion. General phenol kind antiseptic noxiousness is bigger, to waste liquid discharge cause pollution, use lesser already. PH is worth (limits 1 ～ ) of test paper of 14 wide chart: Usually PH value should be in 8.

3 ～ 9.

2 between it is normal to be (specific limits is accurate) with manufacturer technology index. The PH value of different breed emulsion is different. When discovering PH value has the liability that reduce, antirust function meets emulsion to drop quickly. Should add a person in time so new cutting juice or add PH to be worth heighten agent (like sodium carbonate) , raise PH cost, make PH value maintains in 8.

3 ～ 9.

2 the left and right sides. Had been worth when the PH of emulsion 9 when, breed of Yu Fan of microbial retort with challenging questions. Holiday stop for a long time when machine, should to fluid box decided at the higher level but not officially announced period beat enters air, in order to prevent the breed of bacterium of oxygen of be disgusted with, at the same time also but eliminate bad smell. When noting person new juice, want a machine tool all round reach inside feed flow system cut bits and smeary wait for content to keep clear of completely, the ability after be being disinfected with antiseptic adds person new juice, do not clean clean be equal to the bacterium that puts in corruption to the middle of new juice to plant. 5 machine tools corrode water-solubility cutting fluid to have good cool performance, but also cannot ignore to the harm of the machine tool. The water in water-solubility cutting fluid is right of the machine tool corroding is action of dribs and drabs, its endanger degree is increased gradually, last a period of time is longer, cause the attention of the person that use very hard. Although endanger the rate that produces breakdown, the problem that the user also won't consider commonly is cutting fluid and give take seriously enoughly. Of such accumulate over a long period corrode what will bring about a machine tool to machine precision to reduce, shortened greatly thereby the service life of the machine tool, till discard as useless. Harm sex basically has the following sides: The lubricant performance of water is bad, and the grease that can sweep the lube on scour off machine tool and sealed bearing. Corrode metallic surface, although water-solubility cutting fluid added anticorrosion part, but be opposite only the work that is processed is useful, not big to machine tool action. The function of anticorrosion agent is to make workpiece surface arises to the greastest extent chemical passivation action. When the machine tool works, as a result of the water in cutting fluid evaporate, the air relative humidity that in the machine tool working area produces is as high as 100% , after the machine tool quits the job, the humidity in air condenses water in the metallic surface of the machine tool, of the machine tool corrode avoid hard. The water in water-solubility cutting fluid is a kind of electrolyte, the machine tool with inside different data is become possibly potential " accumulator " . When person of ooze of water-solubility cutting fluid, the water in cutting fluid makes the different metal of mutual contact produces electric corrode possibly, electric corrode may be caused rusty, light person the precision that affects a machine tool, machine tool of the person that operate difficult; to weigh cannot be used. The bacterium in water-solubility cutting fluid is the another reason that generation corrodes, can corrode quickly again at the same time undertake. Content of the bacterium in cutting fluid is high, the anticorrosion in changing cutting fluid possibly the chemical function of the agent, those who make is invalid, more very is, bacterial breed can bring about cankerous happening, make between machine tool component corrode speed to increase significantly. The water quality of a material that if use attenuant cutting,enrichs fluid is very poor, contain more mineral, so produce cankerous possibility to also can increase greatly. Cutting fluid is like to elastomer. Form circle, washerbed down the livestock, sealing ring also produce effect. 6 cankerous control and eliminate apparent, fluid of use water-solubility cutting, the user is arranged surely safeguard in the machine tool make great efforts more with administrative field, with controlling cankerous generation, basically eliminate even corrode. To prevent water to be corroded to metallic surface, often should undertake to the machine tool sufficient oil-lubricated, to the grease of significant position daub of the machine tool. Control the chroma of cutting fluid well and truly, when machine tool shutdown, rinse surface of clean machine tool with cutting fluid, and should open machine tool shield, in order to break up the wet moist air of area of machine tool work. To prevent the happening of electric corrode, should go up in metallic surface daub lube of a waterproof fat. And should make a machine tool strict ground ground connection, make ground connection of electric equipment ark is insufficient only, to avoid a bacterium cause and breed, should fixed cleanness or change cutting fluid, keep clear of in time cut bits, and should use soft water (the clean water with mineral low content) attenuant cutting condenses fluid. Be in abroad, a few developed countries are chosen in what have liquid of water-solubility metal cutting when, while contented cutting machines craft to ask, pay attention to its to healthy to person harm, waste liquid is handled and become what wait for a respect originally integratedly to choose more; This one viewpoint is accepted by place of industry of treatment of domestic metal cutting gradually. Water-solubility cutting fluid defends management in use process proper, can obtain optimal cutting to machine the effect not only, and the service life that can prolong water-solubility cutting fluid greatly, reduce waste liquid discharge capacity, achieve earnings of the oldest economy thereby.
