Dab tsi yog cov khoom siv thiab cov qauv ntawm txoj siv xuab zeb, thiab lawv yuav cuam tshuam li cas nws cov nyhuv sib tsoo?

Cov khoom siv thiab cov qauv ntawm cov kabmob Abrasive
Ib txoj kev muaj abrasive yog tsim los ntawm peb ntu: cov khoom siv hauv paus, cov abrasive, thiab cov nplaum.
Cov khoom siv hauv paus: cov khoom siv hauv paus yog zoo li "Skeleton" ntawm cov abrasive siv, tuav cov abrasive thiab cov nplaum. Cov ntaub ntawv hauv paus suav nrog cov ntaub qhwv paj rwb, hluavtaws hluavtaws, thiab ntawv. Qhov zoo tshaj ntawm cov khoom siv hauv paus ncaj qha cuam tshuam yuav ua li cas hloov tau, hnav tau zoo, thiab ntev- kav cov abrasive yog. Piv txwv li, txoj hlua khi uas muaj abrasive nrog cov ntaub paj rwb lub hauv paus yog qhov hloov tau yooj yim thiab zoo rau kev sib tsoo cov chaw nkhaus. Tab sis cov uas muaj daim ntawv pib yog sib dua thiab pheej yig dua.
Abrasive: cov abrasive yog zoo li "cov hniav" ntawm cov abrasive siv thiab nws ncaj ncaj rau kev sib tsoo txheej txheem. Cov abrasives albasives yog txhuas oxide, silicon carbide, zirconium corundum, thiab lwm yam. Cov abrasives sib txawv nyias muaj nyias qhov nyuaj thiab hnav tsis kam, thiab lawv haum rau cov ntaub ntawv sib txawv thiab kev sib tsoo. Piv txwv li, txhuas oxide abrasive muaj nruab nrab hardness thiab yog qhov zoo rau kev sib tsoo cov hlau thiab ntoo. Silicon carbide abrasive yog qhov nyuaj thiab tsim nyog rau sib tsoo nyuaj {}- cov txheej txheem cov ntaub ntawv zoo li cov khoom siv nyuaj.
Cov nplaum: Cov nplaum yog muaj los lo rau cov abrasive khov kho rau cov khoom siv hauv paus thiab nres cov abrasive los ntawm kev tuaj sib tsoo. Cov nplaum nplaum yog tsiaj kua nplaum thiab cob. Hom thiab kev ua tau zoo ntawm cov nplaum kuj cuam tshuam rau txoj siv kev abrasive zoo li cas grinds thiab ntev li cas nws kav.
Tus qauv ntawm txoj siv Arrasive tseem ceeb heev. Cov abrasas yuav tsum kis tau tusyees ntawm cov khoom siv hauv paus, thiab qhov loj thiab cov duab ntawm cov abrasive hais yuav tsum zoo ib yam. Qhov no ua kom paub tseeb tias cov nyhuv sib tsoo yog txawm thiab ruaj khov. Tam sim no, muaj ntau cov kabmob abrasive siv electrostatic cog thev naus laus zis cog cov abrasive nkaug ensal thiab ncaj ncees rau ntawm cov khoom siv hauv paus. Qhov kev sib tsoo no zoo heev thiab zoo ntawm txoj siv abrasive.

Yuav ua li cas cov hmoov phem ua si sib tsoo los ntawm dov
Cov txheej txheem ntawm abrasive siv sib tsoo yog qhov yooj yim zoo nkauj. Nws tau ua los ntawm cov dov ntawm cov abrasas txoj siv abrasas. Tshwj xeeb:
Txhim kho cov abrasas: tso cov abrasive tso rau ntawm lub log tsav thiab lub log tsis sib haum, thiab kho qhov nro. Feem ntau, lub log tsav yog tig los ntawm lub cev muaj zog los muab lub zog rau cov abrasive. Lub log tsheb nro yog siv los ua kom cov abrasive siv nruj thiab nres nws los ntawm loosening lossis plam thaum lub sij hawm sib tsoo.
Hu rau cov workpiece: muab lub workpiece nyob rau hauv lossis ib sab txoj siv abrasive ua kom cov abrasive siv cov abrasive kov lub npoo ntawm workpiece. Raws li cov kev xav tau sib tsoo, koj tuaj yeem kho qhov kev sib cuag siab thiab lub kaum txoj siv abrasive thiab lub workpiece.
Dov sib tsoo: Thaum lub log tsav pib tig, txoj siv abrasive dov ib yam nkaus. Thaum lub sij hawm dov, cov abrasive yuam cle thiab txiav qhov chaw ntawm workpiece, maj mam tshem cov khoom ntawm cov npoo thiab tau txais kev sib tsoo. Vim tias txoj siv sia uas dav dav dav thiab hloov tau, nws tuaj yeem ua cov haujlwm ua haujlwm ntawm cov duab sib txawv thiab nkhaus.
Thaum lub sijhawm cov txheej txheem sib tsoo tag nrho, cov khoom siv thiab cov qauv ntawm cov muaj kev txwv tsis tau siv tau yog qhov tseem ceeb heev. Piv txwv li, qhov hloov tau ntawm cov khoom siv hauv paus txiav txim siab yog tias txoj siv abrasive tuaj yeem coj cov chaw caws pliav. Lub hardness thiab hnav tsis kam ntawm cov abrasive txiav txim siab cov kev sib tsoo ua tau zoo thiab muaj txiaj ntsig. Qhov kev ruaj khov ntawm cov nplaum ua kom paub tseeb tias abrasce tsis tuaj thaum sib tsoo. Nyob rau tib lub sijhawm, cov tsis muaj xws li cov dov nrawm thiab hu rau kev siv lub zog ntawm cov kev npau taws tuaj yeem hloov kho kom tau sib tsoo sib tsoo sib tsoo.
