Cutting fluid by a variety of superfunctional additives through scientific composite fit, and has good coolingperformance, lubricating performance, rust resistance, oil removal the functionof cleaning, corrosion, easy dilution characteristics. To overcome thetraditional soap emulsion summer winter easy smelly, difficult dilution, antirust effect difference problem, and has no adverse effects on the lathe forblack metal paint, cutting and grinding, grinding is the current most. Leadingindicators are better than the saponification of cutting fluid it has good oil,cooling, cleaning, rust and other characteristics, and has non-toxic,tasteless, no corrosion on the human body, the equipment corrosion, thecharacteristics of environment pollution.
The cutting fluid can be divided into straightoil,water-based emulsion, or soluble oil,semisynthetic cutting fluid andsynthetic cutting fluid. The emulsion, semi synthetic and syntheticclassification usually depends on the basis of oil products in the category:the emulsion is only with mineral oil as base oil soluble cutting fluid; semisyntheticcutting fluid containing both mineral oil and base oil containing chemicalsynthesis of water-soluble cutting fluid; synthetic cutting fluid is only theuse of chemical synthetic base oil (which does not contain mineral oil) watersoluble cutting fluid. The cutting fluid of each type will contain a variety ofadditives in base oil outside: anti rust agent, nonferrous metal passivation ofcorrosion agent, defoaming agent and so on. Some manufacturers will have aclassification of micro emulsion; usually considered between emulsion and semisynthetic cutting fluid categories. Diluted emulsion is milky white inappearance; dilution semi synthetic fluid is usually translucent Some productsare milky white; the dilution of the synthetic solution is usually completelytransparent, such as water or a certain color.
Lubrication of metal cutting fluid (thecutting fluid lubrication) in the cutting process, can reduce the rake face andchip, flank and inter surface friction, forming part of lubricating film,thereby reducing the cutting force, friction and power consumption, reduce thetemperature of the wear surface and the cutting tool and the workpiece blankthe friction parts, improve the cutting performance of the workpiece material.During the grinding process, adding grinding fluid, grinding workpiece and thelubricating film formed between the abrasive and grinding fluid into thegrinding wheel, the friction interface decreases, prevent the abrasive cuttingedge wear and adhesion of the chip, thereby reducing the grinding force andfriction heat, improve the durability of the grinding wheel and the workpiecesurface quality.
The cooling effect of cooling liquid iscutting through it and by cutting a heating tool (or wheel), chip and workpiecebetween convection and evaporation, the cutting heat from tooling A place away,thus effectively reducing the cutting temperature, reduce the deformation ofthe workpiece and the cutting tool heat, keep tool hardness, improve themachining accuracy and tool durability. The cooling performance of cuttingfluid and its thermal conductivity, specific heat, heat of vaporization andviscosity (or liquidity). The thermal conductivity and heat capacity of wateris higher than that of oil therefore, the cooling performance of water isbetter than cleaning oil. During the metal cutting process, cutting fluid hasgood effect of cleaning requirements. To remove debris and produce chips, iron,oil and sand, prevent the machine tool and the workpiece, the tool ofcontamination, so that the cutting edges of the tool or grinding mouth to keepsharp, does not affect the cutting the effect for oil based Cutting Oil, lowerviscosity, cleaning ability is stronger, especially with kerosene, diesel oilcutting and other light components, permeability and cleaning performancebetter. Water-based cutting fluid containing surfactant, the cleaning effect isbetter, because It can form film on the surface, to prevent the sludgeparticlesand adhesion in the workpiece, cutting tool and grinding wheel, at the sametime it can seep into the sludgeparticles and adhesion of the interface, itseparated from the interface with the cutting fluid, cleaning rust away, keepthe interface.
In the process of metal cutting work andenvironmental media and cutting fluid component decomposition or oxidation andsludge produced with the corrosive medium and corrosion, the surface of machineparts in contact with the cutting fluid will be corrosion. In addition, betweenthe workpiece or the process of the transfer process also requires temporarystorage, cutting fluid has certain anti rust capability, to preventenvironmental media the residual sludge in cutting fluid and other corrosivesubstances to cause erosion of metals. Especially in the south of our country,humid and rainy season, more attention should be paid to rust.
