Kev paub ntawm cov ntaub ntawv thov thiab cov txheej txheem rau kev txiav cov log sib tsoo

I. Cov kev nkag siab yooj yim ntawm kev txiav cov log sib tsoo

Kev sib tsoo cov log, raws li indispensable cov cuab yeej sib tsoo hauv cov txheej txheem niaj hnub, muaj cov qauv tseem ceeb muaj li abrasive, binder, thiab pores. Hauv kev ua kom zoo nkauj ntawm archoration, ib qho - ceev sib tsoo cov log tsheb sib tsoo, ua kom sai thiab meej txiav ntawm cov hlau loj. Siv lub j3gy - ld-400A tej tshuab ua haujlwm yooj yim, nrog kev sib tsoo ntawm 2800mm

 

 

Ii. Keeb kwm kev tsim kev sib tsoo cov log

 

  1.Lub Sij Hawm Germination: Qhov Kev Siv Txheej Txheem ntawm ntuj abrasives (los ntawm prehistoric lub sij hawm rau lub xyoo pua 18th)
      Kaj ntug ntawm kev sib tsoo hauv cov hnub nyoog pob zeb
Tib neeg tau pib siv cov cuab yeej pob zeb rau kev sib tsoo hauv lub pob zeb matriarchal thiab cov pob txha ua los ntawm cov pob zeb pluaj, ua liaj ua teb, thiab lub neej txhua hnub.
Tuam Tshoj tau mastered thev naus laus zis ntawm cov pob zeb sib tsoo hauv lub hnub nyoog Neolithic hnub nyoog. Piv txwv li, tus 6,000 - lub xyoo qub pob zeb thiab cov kab tsuag tsis zoo nkauj ntawm cov kab sib tsoo, zoo li cov txheej txheem kev sib tsoo ntawm cov txheej txheem qub.
     Cov qauv ntawm cov qauv ntawm cov cuab yeej siv qub sib tsoo
      Cov dej zeb ntawm sab qaum teb wei dynasty: Cov dej zeb tsim los ntawm Cui Liang rau cov nplej ua cim thawj kauj ruam ntawm kev siv tshuab ntawm kev sib tsoo tshuab.
       Ntau - Disc Pob Zeb Zeb ntawm Jin Dynasty: Liu Jingxuan lub creation ntawm ib yim -}}}}}}}}}}}}}}}}} ntuj pob zeb sib tsoo ntau pua.
      Cov coated abrasives ntawm Yuan dynasty: Suav cov neeg tau siv cov ntoo ntawm cov pos hniav uas txuas rau cov khoom sib txhuam, yuav luag ib txhij nrog cov neeg Italians uas siv cov tswv yim zoo sib xws.

 

 

2.Qhov kev txwv thiab kev sib tawg ntawm ntuj abrasives thaum lub sij hawm industrial puag ncig (18 xyoo pua mus rau hnub 19th caug xyoo)

    Kev txwv ntawm cov abrasives
Nrog rau kev txhim kho kev lag luam, cov abrasesive xws li corundum thiab topaz tau muaj qhov tsis txaus ntseeg tau rau kev ua siab rau kev ua siab siab - hadness cov ntaub ntawv.

    Yug ntawm hluavtaws abrasives
Xyoo 1893, piv txwv li Acheson ntawm Carborundum lub tuam txhab hauv Tebchaws Asmeskas Carbide (Sic)
Tom qab, hluavtaws corundum abrasive tau qhia, xaus txoj kev cia siab rau pheej yig, ruaj khov, ruaj khov, thiab siab {cia cov cuab yeej sib tsoo.

 

  3.Modernization Transformation: Cov neeg muaj abrasetic thiab thev naus laus zis tshiab (thaum ntxov xyoo pua 20th mus rau nruab nrab-20th caug xyoo)
    Qhov sawv ntawm kev sib tsoo ceramic sib tsoo
Xyoo 1877, lub tuam txhab Norton hauv Tebchaws Meskas ua ntej siv cov abrasives ua rau tsim cov roj sib tsoo, ua kom tau zoo ua qhov tseeb thiab ua tau zoo.
    Ceramic sib tsoo log yog tsim ntawm cov ntsiab lus ceramic thiab xyoob, haum rau high {{{1} {} duty {{1} {} duty - DEJ DEJW sib tsoo cov ntawv thov.
Daim ntawv thov ntawm cob thiab cov neeg sawv cev sib tham
Cov neeg sawv cev ntawm cov neeg sawv cev, vim lawv qhov kev hloov pauv siab thiab maj mam ua tiav, maj mam dhau los ua cov khoom siv muag, tshwj xeeb tshaj yog rau cov khoom muag khoom.
Hlau Bonding Tus Neeg Sawv Cev Sib Tsoo Yuav Sib Tsoo, nrog lawv cov ris muaj zog tiv taus, yog siv hauv qhov siab - precision com ua teb.

 

4.Qhov ERA ntawm kev ua haujlwm siab: cov kev sib faib thiab cov ntawv thov ntawm cov ntaub ntawv superhard (nruab nrab-20th los qhia)
    Qhov kev hloov pauv ntawm superhard abrasives
     Pob Zeb Diamond Sib Tsoo Log: Raws li cov khoom siv nyuaj tshaj plaws, cov pob zeb diamond sib tsoo tau siv dav hauv cov khoom siv hluav taws xob, cov khoom siv kho mob, thiab lwm thaj chaw. Lawv txoj kev nyuaj heev tuaj yeem txuas ntxiv lub neej ntawm kev txiav cov cuab yeej thiab nce cov khoom siv tshem tawm.
      Cubic Boron Nitride (CBN) Sib Tsoo Log: Haum rau kev sib tsoo cov ntaub ntawv ferrous xws li cov hlau tawv thiab cov hlau pov tseg, lawv yog qhov tseem ceeb ntawm tus nqi ntawm Aerospace thiab kev lag luam tsheb.
   Tsim Tsim Kev Sib Tsoo Log
Txhawm rau hais txog cov teeb meem ntawm kev sib tsoo siab thiab kub nyob rau hauv cov tsoos sib tsoo log, xws li cov uas muaj cov kab sib tsoo) tau raug npaj siab.
Los ntawm kev ua kom zoo dua cov qauv tsim qauv, kev sib tsoo log txo qis kev sib tsoo, qis dua thiab ntsuas qhov chaw ua haujlwm.

 

 

 

III. Precision Raug Cov Txheej Txheem

Kev ua yeeb yam ntawm kev sib tsoo log yog txiav txim siab los ntawm peb qhov tseem ceeb: Cov yam ntxwv abrasas, grit loj piv, thiab hom ntawv sib piv. Resin - b) domed sib tsoo log (b) dominate nyob rau hauv kev ua ntawm nyuaj alloys vim lawv tus kheej zoo heev} Lub zog ntse; Thaum hlau {- be}} nkhaus sib tsoo cov log (m) yog qhov haum rau hnyav- koj lub luag haujlwm zoo tshaj. Kev xaiv ntawm grit loj ncaj qha cuam tshuam rau saum npoo av roughness ntawm cov khoom siv ua; Piv txwv li, W20 micro -} grit sib tsoo cov log tuaj yeem ua tiav daim iav tiav nrog qhov chaw ntawm RA0.2μm.

 

 

 

IV. Kev Nyab Xeeb Kev Ua Haujlwm Tshwj Xeeb

    Txhim kho thiab tshuaj xyuas: Maj mam coj mus rhaub rau sab sib tsoo nrog lub tshuab xaws nylon. Lub suab ntshiab qhia tias tsis muaj kab nrib pleb. Lub cheeb ntawm chuck yuav tsum tsis muaj tsawg tshaj li ib-
Tiv thaiv cov khoom siv: Qhib lub kaum sab xis ntawm cov npog tiv thaiv yuav tsum tsis pub ntau tshaj 125 degree. Qhov dav ntawm lub chip zov yuav tsum tau tshaj lub voj voog sab nraud ntawm lub log sib tsoo los ntawm 20mm. Qhov sib txawv ntawm cov khoom siv tau zoo thiab cov ua haujlwm yuav tsum tsis pub ntau tshaj 3mm.
 Kev ua haujlwm taboos: Sab sib tsoo yog prOhibited. Kev khiav hauj lwm ncaj qha nyob rau hauv pem hauv ntej ntawm lub log sib tsoo yog txwv. Siv cov qhov cub tawg sib tsoo yog txwv tsis pub.

 

 

V. Cov ntsiab lus tseem ceeb rau kev saib xyuas thiab kev saib xyuas

    Kev Soj Ntsuam Txhua Hnub: Ua ntej siv, xyuas kom meej tias cov kev sib tsoo log tsis muaj radial tawg (nrhiav kom zas xim rau txoj kev), thiab lub suab nrov ua haujlwm yog tsawg dua lossis sib npaug ntawm 85 dB.
   Hnav khaub ncaws: Kho cov log yuav tsum tau hnav khaub ncaws nrog lub pob zeb diamond diamond tom qab ua 500 daim. Rau cov hlau sib tsoo cov log, electrolytic hauv - txheej txheem hnav ris tsho kom zoo.
   Cov Lus Qhia Cia: Khaws rau hauv ib puag ncig nrog cov txheeb ze ntawm tsawg dua los yog sib npaug los tiv thaiv cov roj hmab sib tsoo kom deb ntawm cov tshuaj oily.
