Besmear is added grind provided choice and use (one)

1 besmear adds grind provided definition and structural besmear to add grind: Be in abrasive conglutinate what make on the base material that can circle music to grind with binder. Besmear is added grind provided structure, if pursue 1. Besmear adds grind provided 3 essential factor: Base material, abrasive, binder, if express 1. Base material: Of abrasive and binder bear the weight of body. Abrasive: Grind the main body binder that has generation grinding and polishing effect: Have the effect of felt abrasive and base material, make grind a form with be had proper and intensity. Besmear adds grind a 9 big characteristic factors: Arenaceous density of processing of base material, base material, abrasive, granuality, establish, binder, bonding strength, appearance, dimension. 1. 2 besmear add those who grind a 3 element to form besmear to add grind provide " 3 element " : Base material, abrasive, binder. Each element has different property and different type stuff to be able to offer an alternative. (1) the classified base material of base material is besmear adds those who grind the abrasive in providing and binder to bear the weight of body. It is besmear is added grind have but the dominant element of bending sex, also be distinction grinds provided main feature at other. The sort of base material basically has paper of paper, cloth, steel, compound base, without spin cloth to wait. Paper: Besmear is added grind using paper is made by the fiber of particularly strong and rich tenacity, make the variety of different character and norms according to different need. The price of paper is cheaper, do not need to undertake base material is handled commonly, dosage is very big. Add in besmear grind in using, the model of paper differentiates with ration, if express 2. Express 2 besmear to add grind a Normal Align=center>Anormal Align=center>Bnormal Align=center>Cnormal Align=center>Dnormal Align=center>Enormal Align=center>Fnormal Align=center>Hnormal Align=center> of model of model Normal Align=center> that uses paper mensurable (G/m2) cloth of Normal Align=center>80normal Align=center>100normal Align=center>120normal Align=center>160normal Align=center>220normal Align=center>300normal Align=center>300: It is raw material with fiber, make the fabric that be organized certainly and forms through spin. Cloth adds the application in grinding provided base material in besmear the widest, flexible good, intensity is high, but need undertakes strict base material is handled; Because cloth does not form different type of the organization together, besmear is added grind be in with cloth at present basically cloth of cotton cloth, blending, polyester cloth waits. Because cloth does not form different type of the organization together, besmear is added grind an organization that uses cloth to at present basically 1/1, 2/1, 3/1, 4/1 waits, different besmear is added wear a cloth that chooses different organization. Add in besmear grind in using, like be the same as paper, cloth differentiates with weight. The level with the weight at present current neither one of cloth, if express,its are classified 3. Express 3 besmear to add wear tag of a classification that uses cloth date Lnormal Align=center>Fnormal Align=center>J Xnormal Align=center>Ynormal Align=center>Snormal Align=center> light-duty cloth is light-duty cloth is medium-sized heavy-duty cloth massiness cloth exceeds cloth paper of heavy-duty cloth steel: Be by multilayer cotton fiber is shirt-sleeve and become, the base material with very high intensity. Can bear particularly high mechanical load, intensity is high, stretchy small, hear resistance is good, basically use at the production of steel paper emery disc, different goods, add according to besmear worry provided demand, with ply choice. Compound base: Mix by paper cloth is compound and into, integrated the advantage of paper and cloth, intensity is high, stretchy and dinky, basically use arenaceous tape of carry on one's shoulder of heavy burden of the high speed that make, little system of quantities makes emery disc. Commonly the type person of cloth radical is the basis light-duty and compound base, heavy-duty and compound base 2 kinds. Without spin cloth: Plant or will count kind of fiber to use the method such as felt or machinery, the made color that does not have cloth via weaving a course and function, basically use make loose polish grind. (2) the phyletic abrasive of abrasive is besmear adds the principal part that grinds a generation grinding and polishing action. Abrasive must have these main character: Certain hardness, particular strength, proper broken sex, stated reason changes stability. Abrasive can be divided for natural abrasive and man-made abrasive two kinds big. Besmear adds grind a commonly used abrasive breed to basically have: Palm corundum (A) : Bases is α - AI2O3, the exterior is shown brown or palm is Brown, hardness is taller tenacity is good, can bear very great pressure, have high temperature resistant, fight corrode, chemical stability is good wait for a characteristic, application is very wide. Bai Gangyu (A) : Bases is α - AI2O3, the exterior shows white, corundum of palm of hardness prep above, the gender is fragile, tenacity is lower than palm corundum, abrasive easy disintegrate, sharp sex is good. Black carborundum (C) : Bases is SIC, exterior darkly is lubricious, hardness tall sex, the gender is fragile, the sharp sex of abrasive is good. Zirconium corundum (ZA) : Bases is α - AI2O3 and AI2O3-Zr in all crystal, the exterior shows hoar or dust-colour, have very good tenacity and wearability, comfortable weigh bear grinding and the treatment that wear metallic stuff hard at high speed. Additional, still have abrasive of pottery and porcelain, glass arenaceous, garnet. Besmear is added grind the technical requirement such as density of the chemical part that has pair of abrasive, granuality, particle shape, accumulation, hydrophily, besmear adds the abrasive that grinds a place to use to want to use besmear to add grind a special abrasive, namely P abrasive. (3) the action that the classified binder of binder is a felt abrasive and base material, make grind a form with be had proper and intensity. Besmear is added grind the binder in providing to wait by glue of base material inorganic agent, bottom, answer glue commonly form. The action of base material inorganic agent basically is to improve the physical machinery performance of base material, assure good gelatinize establish arenaceous quality, gift the performance characteristics with good product. According to the product different use asks, blame of cent of base material processing is able to bear or endure water treatment and be able to bear or endure water treatment, base material inorganic agent should suit to it. Bottom glue is the coating that gets on abrasive felt in base material, have felt and the effect that secure abrasive. Answer glue is to be in what already secured to grind bead to go up to besmear again a binder, surround abrasive the letter enhances the bonding strength that grinds bead and base material further thereby, assure to grind bead to be able to experience the extruding of grinding force and the effect that pound and fall off not easily in grinding process. Affecting besmear to add the main factor that grinds a bonding strength is the sort of binder and amount. Besmear adds the binder that grinds a place to use to basically have: Animal glue, synthetic resin. Colophony of aldehyde of exemple hide glue, Niao, phenolic aldehyde colophony, epoxy resin, alkyd. Animal glue: Felt performance is good, use convenient, but do not be able to bear or endure water, easy be affected with damp be affected with damp. Niao aldehyde colophony: Make simple, cost is low, glue of animal of excel of felt function, moistureproof fungus resistance. Phenolic aldehyde colophony: Bonding strength is high, be able to bear or endure water, fight acid, be able to bear or endure it is good to await a gender, especially resinous of water-solubility phenolic aldehyde is used, make become besmear to add those who worry an industry one of the mainest binder. Epoxy resin, alkyd: Felt performance is good, be able to bear or endure ability in swimming is good, but need to use organic dissolvent, over be able to bear or endure the production of waterproof abrasive paper. 1. 3 besmear are added grind classify besmear to add really grind providing is by base material, abrasive and binder 3 parts are comprised. According to base material, abrasive and binder different, besmear is added grind can divide for numerous breed, have different function and different use. Scientific and reasonable besmear is added grinding provided classified means is to choose besmear to add grind when providing important basis. (1) add according to base material and besmear of use method classification grind a cent to wear emery cloth to work, be able to bear or endure water emery cloth, dry grind sand paper, be able to bear or endure waterproof abrasive paper (2) classify besmear to add according to binder and base material processing grind a cent to be besmear of animal glue felt to add grind, colophony felt besmear is added grind, besmear of complete colophony felt is added grind, be able to bear or endure water besmear is added grind provide 4 kinds big. (3) according to abrasive material qualitative, granuality classifies: Abrasive material shows the sort of abrasive and performance character, the bulk that abrasive size represents to wear bead and distributinging condition. Material pledges and granuality can divide different abrasive to be added for different besmear grind a breed. Additional, dry grind emery cloth and be able to bear or endure waterproof abrasive paper still has a kind of code name, be aimed at distinct size, still have on the market at present use. (4) according to establish arenaceous density classifies: State besmear adds the density that grinds a surface to wear bead. Besmear is added grind branch of provided establish arenaceous density to be close planting arenaceous (CL) scanty establish is arenaceous (OP) . (5) classify according to product figure: Besmear adds grind a basis product figure can divide for: Page shape, roll shape, banding, dish shape, different article. Numerous classified method, which kinds more scientific, more intuitionistic, more convenient? We think " classify according to binder and base material processing " a few more reasonable, again with " the classification according to product figure " be united in wedlock, basically can satisfy pair of besmear to add grind provided description. Binder and classification of base material processing can divide the basis to be added for animal felt besmear grind, colophony felt besmear is added grind, besmear of complete colophony felt is added grind, be able to bear or endure water besmear is added grind provide 4 kinds big. Besmear of animal glue felt adds grind: Code name all uses animal gum for G/G bottom, answer glue, cheap base material inorganic agent, hear resistance, be able to bear or endure wet sex is poor, but binder is water-solubility, valence cheap, make simple, use convenient. Besmear of half colophony felt adds grind: Code name is R/G, bottom glue is animal glue, answer glue is synthetic resin binder, in cheap base material inorganic agent, characteristic interpose is mixed at animal glue between complete colophony product. Besmear of complete colophony felt adds grind: Code name is R/R, bottom, answer glue all uses resin combining an aspect, high-grade base material inorganic agent (do not be able to bear or endure water or have water proofing property) , bonding strength is high, wearability is good, heat-resisting, basically apply at mechanical grinding. Be able to bear or endure water besmear adds grind: Code name WP, base material should undertake water or oil resistant are handled is able to bear or endure beforehand, bottom, answer glue uses synthetic resin or paint, apply to use in water quality cooling fluid. 1. The basic knowledge arenaceous belt of 4 arenaceous belts is cricoid besmear is added grind. As a result of the generation of arenaceous belt, just make besmear is added grind an implementation the change that applies to modern grinding means from handiwork. Arenaceous belt cent is without contact arenaceous belt, contact arenaceous belt. Contact arenaceous belt divides the connect that it is sheet, much connect, gyroidal connect. Contact form has build receive law and butt joint standard. Receive for straight knot to receiving a law to be divided again, S form butt joint, rabbet. 2, besmear is added grind a grinding basic knowledge 2. 1 besmear is added grind provided grinding place and suitable scope besmear to add grind providing is a kind when make by abrasive, base material and binder flexible grind. Besmear adds those who grind provided grinding to have flexibility, the grinding content dot of efficient cold cutting, apply extensively at: (1) large planar thick, thin board, include the treatment of metal tape material; (2) the treatment of large quantities of all sorts of metals that estimate production, metalloid workpiece; (3) complex model of face workpiece shape grinding and polish; (4) of material of the metallic canal of all sorts of diameters, club, roller outside grinding of round grinding, curved curved surface, inside round grinding. (5) use page annulus or canister molding sand to cover the polish that can replace rag wheel; (6) dish state product wears welding line with what wait at large housing, casing, hull, bridge, go burr, large area divides the side such as rust, efficient, convenient, safe. 2. The grinding mechanism besmear of 2 arenaceous belts is added grind understandable to have numerous the much knife that grinds bead to form is much the cutting tool of blade. Besmear is added grind provide wearing bead is even ground distributings in base material surface, basically be monolayer distributings. Besmear adds the special abrasive that grinds a place to use, its are basic bead content demand is higher, grain size is even, make besmear adds those who wear a face to ground bead to have wait very well tall arrange. Especially modern besmear is added grind a production to use electrostatic plant arenaceous technology, outside assuring to grind the pointed horn day of bead, abrasive is directional arrange. Besmear adds those who grind a surface to wear bead to be smoked surely arrange and wait for tall sex, it is besmear is added grind those who maintain grinding is efficient the main factor with cold conditions grinding. Depend on with the typical distinction of emery wheel grinding " arenaceous belt grinding is take perpendicular negative charge through rising (grinding pressure) , do not rise through raising arenaceous belt speed to spend development. The linear velocity of arenaceous belt is commonly inside 15-35 M/s limits, exceed 50m/s rarely. Arenaceous belt is in grinding process, produce 3 different courses: Slippery brush -- those who grind bead to go up in workpiece is slippery brush, the flexibility that produced workpiece material is out of shape, plough -- the plasticity that grinds bead to cause workpiece material flows, make material produces extruding type move move and squeeze with two side ahead from the lower part that wear bead piece, excise at the same time a few material; Cutting -- material ruptures in slip ahead generation and form cut bits, have quite rapid excision rate. Above 3 processes are mutual connective, among them cutting is the most effective form in grinding process. Arenaceous belt if grinding mechanism signal pursues 2 CNC Milling CNC Machining
