Tai yra a labai realus jausmas už the application of
"Grinding King" will give you an analysis of the manufacturing method of superhard abrasive tools from the grinding performance, and remind the brothers who only bury themselves in the formula. This might be a wake-up call.
Aukštas efektyvumas šlifavimas technologija yra būtina sąlyga pažangi gamyba technologija , visiškai išsprendžia apdorojimas apribojimai didelis tikslumas ir žemas efektyvumas tradicinis šlifavimas apdorojimas.
Nors gavimas aukštas efektyvumas ir didelis tikslumas, it gali taip pat procesas įvairūs medžiagos ir formos su aukštu paviršiumi vientisumas ir sumažinti išlaidos. Pagal the present conditions of our country, it is of great significance to strengthen the research, popularization and application of high-efficiency grinding technology to improve the processing level of our country's machinery manufacturing industry and accelerate the development of new produktai. Šiais laikais, the application of superhard materials is inmillennialy extensive, and the implementation of high-speed and efficient grinding is the preferred processing technology for processing superhard materials and hard-to-cut materials. Due to the application of superhard abrazyvai, high

"Grinding King" : The high-efficiency grinding wheel should have good wear resistance, high dynamic balance accuracy, crack resistance, good amortization, high stiffness and good thermal laidity, and its mechanical strength must be able to withstand the cutting force during high-efficiency grinding. High efficiency šlifavimas wheels can use corundum, silicon carbide, CBN, diamond abrazyvas. Under the conditions of suitable binder and advanced manufacturing process, the production of abrasive tools can be used at speeds up to 125m/s.
Esamas keramika surištas šlifavimas ratas yra atsparus į į vandenį, alyva, rūgštis ir šarmas korozija, ir gali išlaikyti the correct geometrija. The porosity is large, the grinding rate is high, the strength is large, the toughness, elasticity, the vibration resistance is poor, can not withstand the side force, the grinding of the V wheel < 35m/s, the grinding machine grinding editor tells you: this binder is the most widely used, can be made into a variety of grinding tools, suitable for forming grinding ir šlifavimas sriegiai, pavaros, alkūninis velenas ir so on." Vyriausiasis redaktorius Mill Wang tells you that many ceramic binders are now applied to higher speeds, 50-80m/s, and many are used in examples.
The existing resin bond is strong and elastic, not afraid of impact, and can work at high speed. It has the effect of friction polishing, but its firmness and heat resistance are poor compared with ceramic binder, it is not resistant to acid and alkali, and its porosity is small and easy to block. V wheel > 50m/s high speed grinding, can be made into a wafer grinding wheel groove grinding tool front cutter face, high precision grinding.
Neorganinis polimeras rišiklis šlifavimas įrankis turi aukštas stiprumas, so it has a didelis greitis of use, paprastai tinkamas for high-speed pjovimas, grubus šlifavimas, sunkus apkrova šlifavimas; In papildymas, the neorganinis polimeras rišiklis šlifavimas has tikras elastingumas, didelis karštis varža iš išteršėjas ir geras šlifavimas savaiminis aštrumas, so kad lyginama su su the tradicic derva rišiklis, the sharp Angle of the grinding wheel is good, the shape sulaikymas yra geras, ir jis is taip pat tinkamas for smulkus šlifavimas, toks as siūlas šlifavimas, formavimas šlifavimas ir galandimas. It gali būti pasakyta kad neorganinis polimeras rišiklis turi abu the performance of keramika abrazyvai ir the performance of derva abrazyvai, ir at the same time vengia jų defektų.

gamyba neorganinis polimeras rišiklis abrazyvai is pagrindas on the the theoretical basis of grinding and application research, and the concept of composite materials is introdukuota į the production of abrazyvus tools, and the basic principles of physical chemistry of inorganic polymer binder (1. The crystal chemistry of inorganic polymer materials 2. Thermodynamics of inorganic polymer materials 3. Procesas dinamika iš neorganinių polimerų medžiagų) ir the interface of composite materials and the strengthening and toughening mechanism are introduced, konkre talking about the application of inorganic polymer bonds in the production of new, high efficiency, special, heavy load strength and precision abrazyvai. Nors šis pažangus procesas technologija turi palaipsniui buvo įvaldyta pagal some tool industries, there are still some specific problems that need to be serious summarizeed and solved.
The following is the specific design principles and methods of inorganic polymer bonding abrazyvai, the production of inorganic polymer composite abrazyvai high speed heavy load, grubus šlifavimas abrazyvai, stiprus šlifavimas abrazyvai, aukštas efektyvumas gilus šlifavimas, lėtas pašaras šlifavimas abrazyvai, greitas taškas šlifavimas abrazyvai, aukštas efektyvumas šlifavimas abrazyvai, velenas ir guolis abrazyvai, aukštas efektyvumas šlifavimas abrazyvai, bėgis šlifavimas abrazyvai, smėlis diržas šlifavimas procesai Metodai To duoti kai kurie paviršutiniški vaizdai.
Pirma iš all, the properties of the apdorota materiali and the accuracy of the material processing surface should be considered, and then the appropriate abrazyvive, particles size and šlifavimas use of mixed abrazyvai should be selected.
Abrazyvai ir abrazyvas storis ir dalelė gradacija in the derinys of abrazyvai matrica
The thickness of abrasives - refers to the overall thickness of abrasives of different particle sizes mixed together; Particle grading refers to the combination or collocation of abrasives of different kinds, sizes and quantities.
Abrazyvas yra an svarbu faktorius in šlifavimas, abrazyvas pasirinkimas is daugiausia pagrįsta on the properties of the ruošinys medžiaga, toks as kietumas, tempimas stiprumas, kietumas ir so on to nustatyti.
Kai šlifavimas medžiagos su žemas tempimas stiprumas, silicis karbidas abrazyvai su didesniu trapumu arba stiprumu turėtų būti pasirinkta.
ruošinys geometrinis tikslumas reikalavimai yra aukštas, kai the abrazyvas ratas ir ruošinys kontaktas plotas is mažas, turėtų pasirinkti smulkus granuliavimas; Kada kontaktas plotas is didelis, pasirinkti šiurkštus grūdas dydis. Ruošinys medžiaga yra kietas ir trapus, ir smulkus granuliškumas turėtų būti pasirinkta;
ruošinys medžiaga minkštas ir kietas, ir šiurkštus grūdas dydis turėtų būti pasirinktas.
Terminis laidumas iš the ruošinys yra prastas, lengva to karštis deformacija, lengva į sudeginti, turėtų pasirinkti šiurkštesnis dalelė dydis.
Šie problemos taip pat įtraukti the terminis laidumas, šiluma talpa, tankis, poringumas ir kiti veiksniai kad veikia šlifuoja.

Abrazyvai yra paprastai padalinti į šiurkščius abrazyvus, vidutinius abrazyvus, smulkius abrazyvus ir mikro miltelius abrazyvus.
Under the same abrasive condition, the total surface area of the micro-powder abrazive is larger, and the total surface area of the coarse abrasive is smaller. In the production of abrasives, the surface needs to be wrapped with a nodule agent to give bonding strength, and the greater the total surface area of the abrazive, the more inorganic polymer bonding agents need to be wrapped on the abrazive surface. Paprastai, the surišimas dozė neorganiniai polimerai naudojami in šiurkštūs abrazyvai is mažiau nei kad naudojami in smulkūs abrazyvai.
Abrazyvas dalelė gradavimas, in order to pagerinti the šlifavimas efektyvumas, not only to apsvarstyti the strength of the abrazyvas ir apdorojimas medžiagos, but also must determine the amount of keli abrazyvai, abrazyvas šlifavimas staklės šlifavimas bendras redaktorius vadinamas the grading of abrazyvas.
Kai šlifavimas, the šlifavimas įrankis is paveikta pagal the impact of the grinding body on the one hand, and the damage of the grinding body on the other hand, so as to ensure the sharpness of the grinding tool and complete the visre grinding process.
Akivaizdu, in the unit time, the more contact points of the grinding body involved in grinding, that is, the more abrazyvas dalelės involved in malimas per vienetas laikas, the higher the šlifavimas efektyvumas.
Kai the abrazyvas is fiksuotas, the contact tarp the abrazyvas ir the šlifavimas kūnas turėtų būti padidintas, ir the small the size of the abrazive, the better.

Bet on the other hand, in order to complete the šlifavimas of the šlifavimas ruošinys, the šlifavimas įrankis must have pakankamas impact talpa.
The task of the grinding tool "grinding king" tells you that it is necessary to ensure sufficient ability to grind the material of the workpiece, and to ensure that the grinding tool grinds the workpiece to a certain fineness, todėl, in the case of certain other conditions (such as the strength of the grinding tool, the speed of the grinding tool, etc.) , this task can only be completed by choosing the tinka size of the abrazyvy and the reasonable proportion of them.
tarpas tarpas tarp abrazyvai in gamyba abrazyvai yra teoriškai generuojama po the rišiklis is padengtas su abrazyvais. In order to pasiekti the purpose of useing less inorganic polymer binder to meet the strength of abrazyvų and to pagerėti the šlifavimas efektyvumas, the gap between abrazyvų turėtų būti sumažintas.
Kitas naudotas koncepcija kad turėtų būti patikslintas is kad žmonės yra įpratę į the ruošinys šlifavimas nudegimai priskirta į į abrazyvą ratą grupę vertę is per tankų, trūkumą išgertu pakanka lustą poringumą.
Per šlifavimas, the poringumas groja the role of chip storage and chip removal, and can contain the coolsky, which is conduive to the dissipation of maling heat. In order to meet some special processing requirements, the pores of traditional abrazyvai can also be impregnuotas with certain fillers, such as sulfur and parafinas, to improve the performance of abrazyvai. This filler is also traditionally known as the fourth element of abrazyvai. Šis yra ne visada tiesa, nes skaičius of chips pagaminta in high-cut šlifavimas is too large to be accommodated by small pores, and the superhard abrazyvas wheel has no poros at all. As long as the surface is properly sharpened, it can work well. If the poros volume ratio of the derva abrazyvas wheel is increased, it will neišvengiama reduce it strength and make it wear preearly, which yra ne verta nuostolis.

In addition, the influence of the grinding wheel working line speed on the number of grinding chips is more complex, when the grinding wheel is increased from 28.8m/s to 33.6m/s, the speed is increased by 16%, and the amount of blockage is increased by three times. Because the increase of the line speed of the grinding wheel reduces the maximum cutting depth of the abrasive particle, the cross-sectional area of the chip decreases, and the cutting times and grinding heat increase, both of these factors increase the amount of plugging, but when the line speed of the grinding wheel is up to a certain degree (such as up to 50m/s or more) the amount of plugging of the grinding wheel is greatly reduced. For each workpiece material, there is a certain critical grinding wheel speed value with minimum plugging amount. The production of inorganic polymer bonding abrasives has little consideration for these, and the grinding theory about these will be introduced again in the future special. If you want to see more about the analysis in the future, please stay tuned. If it feels valuable, the positive energy transmitted by the editor-in-chief "Mill King" is transmitted by relay.
