Cutting fluid is offerred for efficient treatment assure reliably

Cooling action. In process of workpiece cutting treatment, drop the temperature of cutting area quickly, at the same time refrigeration can assure to machine efficiency of precision, cutting and cutting tool life, avoid the generation of knife tumour. 2.

Lubricant action. Can reduce the attrition between cutting cutting tool and workpiece, lubricating fluid can infiltrate cutting tool and workpiece reach his to cut bits between, amid forms a compact covering layer, reduce attrition and felt, reduce cutting resistance, reduce attrition heat, assure to machine precision, improve cutting tool life. 3.

Clean action. The treatment area of rinse out cutting tool and workpiece cuts bits, in case they mutual felt and conglutinate are on workpiece, cutting tool and machine tool, cloggy surface is bright and clean spend or destroy treatment face. 4.

Antirust action. Can prevent workpiece and machine tool to rust, and between working procedure short-term and antirust. Afore-mentioned refrigeration, lubricant, clean and antirust 4 action are mutual and diversionary, accordingly, overall balance advantages and disadvantages wants when choosing cutting fluid. Additional, cutting fluid still can reduce cutting temperature and exterior surface roughness effectively, reduce cutting resistance, improve the service life of cutting tool and emery wheel, improve manufacturing efficiency and product quality thereby. The choice of cutting fluid asks to process data with what material pledges in the light of different treatment craft, need chooses to emphasize particularly on the cutting fluid of different function, and its long-term and strict control is inside stabler target range. 1.

According to engine of craft choice car main component is the treatment craft of main part cutting treatment and abrade treatment. If broaching, delay takes class grinding, gun getting, tap, car,sell, bore, whorl, bore hole to wait with section plane. (1) in the rough machining in taller cutting speed (for example, turning, milling and auger cut) , requirement cutting fluid has good cool performance, should choose fluid of water radical cutting and low density emulsion. (2) when undertaking deep Kong Zuan processes work, because cutting tool slightness, stiffness is poor, easy cause cutting tool deflective reach chafe with hole wall, arbor is easy happen be out of shape reach vibration, and cut bits the problem such as not easy eduction, need chooses the cutting fluid with cool good performance, because attrition is reached,eliminate be out of shape the quantity of heat of generation, restrain those who accumulate bits tumour to generate. At the same time need has good high temperature lubricity and osmotic, make cutting fluid can permeate edge in time to go up, make sure broach holds good lubricant position below the high temperature of cutting area. Make cut bits can successful eduction. When undertaking grinding processes work, the grain of metallic useless bits that machines generation as a result of cutting tool is very little, treatment precision is tall, need the cutting fluid that lubricant function actors or actress, can satisfy treatment requirement already, can take away useless bits again and do not injure treatment work area.

Choose workpiece material character according to workpiece material but cutting sex has important sense to the choice of cutting fluid. The particular case that cutting machines and demand are diverse, the difficult easy level that cutting machines is different. When rough machining, of requirement cutting tool wear away productivity of slow, treatment is tall; When finish machining, requirement workpiece has taller precision and lesser exterior surface roughness. To the material of difficult treatment, should choose active tall, contain fight grind, extremely the cutting fluid that presses additive; Choose to the data that processes easily do not contain extremely the cutting fluid that presses additive. From the cent on treatment workpiece material, alloy of cast-iron, aluminous, titanium, aluminium alloy and alloy steel wait. (1) need to choose the cutting fluid with antirust strong function when cast-iron treatment. Cast-iron wait with bronze when be brittleness material, cutting middling forms collapse to break cut bits, flow easily everywhere along with cutting fluid, flow into a machine tool component damage is caused between slideway, can use refrigeration and the emulsion with clean function good. (2) when be being machined to aluminous goods, because the aluminous material of certain order and degree is had " agglutinant " and pull end, cannot use free cutting treatment. Some aluminium alloy are very hard and wearability is tall, need the cutting fluid with lubricant high performance. (3) titanium alloy, aluminium alloy and alloy steel (add) when cutting nonferrous metal and light metal, cutting force and cutting temperature are not high, can choose mineral oil and high concentration emulsion. When cutting alloy steel, if cutting measures surface roughness of inferior, surface the requirement is lesser (be like broaching and whorl cutting) , need the cutting fluid of exceedingly good and lubricant function right now, can choose extremely press cutting oil and high concentration emulsion. 3.

In choosing the high strenth in a few nicety to machine according to processing cutting tool data (for example, broaching, tap, deep Kong Hezuan is cut) , need cutting fluid has superior lubricant performance, can choose extremely press cutting oil and high concentration emulsion. (1) the heat-resisting temperature of tool steel cutting tool is in 300 ℃ of 200 ～ , heat-resisting performance is poor, hardness is lost below high temperature, because this requirement uses cooling property fluid of cutting of good, low pH indicator. (2) when high-speed steel cutting tool undertakes high speed thick cutting, cutting amount is large, produce many heat in metal cutting, the water with should use cooling sex good base cutting fluid; When the precision work that if use high-speed steel cutting tool,has medium, low speed, adopt fluid of oil radical cutting or high concentration emulsion commonly, can reduce the attrition cohere of cutting tool and workpiece, restrain cutting tumour to generate, raise treatment precision. (3) melting point of hard alloy cutting tool and hardness are taller, chemistry and thermal stability are better, cutting and wear-resisting performance are better than high-speed steel cutting tool much, liquid of oil radical cutting can be used in common treatment. If be heavy cut, cutting temperature is very high, wear away easily lickety-split cutting tool, should increase the flow of cutting fluid right now, make sure enough refrigeration is lubricant. (4) cutting tool of pottery and porcelain, diamond cutting tool and cubic nitrogen change boracic cutting tool to have taller hardness and wearability, cutting liquid is not used commonly when cutting, also can use liquid of water radical cutting sometimes. After the solves measure to choose to suit cutting fluid that cutting fluid sees a problem in treatment middling, still need to had done its quality control, government, ability comes true " fall this synergism " . Precautionary cutting fluid solves measure of the problem of likelihood happening to basically include quickly: 1.

Bacterial odor problem, this makes jockey person feel disgusted not only, can cause cutting fluid sometimes degenerative, damage workpiece, make filter equipment safeguards difficulty, the of all kinds shadow cost such as cutting tool life rises. Once discover need joins curb bacterium agent to undertake controlling instantly, notice to complement everyday a few new juice. 2.

Bubble problem, this meeting is brought about excessive drain cutting fluid, cause filter not free, head of block up knife comes loose hot. In high agitate system, when easy bubbly cutting fluid enters zone time of work of cutting tool edge, overmuch bubble can pose problem of cutting fluid memory, make cutting tool life not stable. To this, can choose blame pure water to add; Or add anti-foaming agent, but the performance that adds juice of meeting influence cutting for a long time. 3.

(Seasonal) rustily appear on workpiece, cutting tool and knife handle to be able to cause the appearance bright and clean degree drop, lower machine tool life. Be in foreland or damper place, want to notice to choose the cutting fluid with antirust good performance, notice the daub of antirust oil between working procedure. 4.

Cut bits to sedimentation the gender differs can refrigerative effect and operating mode aggravation, bring about cost to rise. Need often open cutting fluid circulatory system, improvement filters system, improve cooling fluid clean a gender. 5.

Skin infection. Should choose pair of human body not to have the product of harm, safe environmental protection that does not have stimulation as far as possible, at the same time jockey person needs to deploy apparel correct fatigue defends articles for use. The normal movement that good lubricant management can be mechanical equipment and life are lengthened provide safeguard, this also is one of main tasks that modern plant manages. The cost of cutting fluid takes whole platform engine about the 2 ％ of cost of production of 4 large crucial parts, but the 70 ％ above that can affect integral finished cost however. So we need to pay close attention to cutting fluid morely, harmonious control is used, managing cost, improve beneficial result. CNC Milling CNC Machining
