Thaum sib tsoo cov hlau tsis zoo, qhov teeb meem tshwm sim yog pom cov cim lossis qhov tsis zoo, xws li tawg, khawb, lossis qhov pores, nyob tom qab ua tiav.
Hais lus nruj me ntsis, qhov no tsis yog ib txwm txhais tau tias cov kev tsis zoo no muaj nyob hauv cov khoom qub. Hauv ntau qhov xwm txheej, tsis tsim nyogabrasive nplejxaiv los yog txoj kev sib tsoo tsis raug tuaj yeem ua kom loj lossis tob zuj zus qhov tsis zoo uas twb muaj lawm es tsis txhob muab tshem tawm kom zoo.
Dab tsi ntawm qhov tsis xws luag tuaj yeem tshwm sim los ntawm kev xaiv cov nplej tsis zoo?
Sib sib zog nqus khawb los yog dents tshwm sim los ntawm kev sib tsoo cov cuab yeej
Qhov teeb meem no feem ntau tshwm sim thaum siv cov kev sib tsoo sib tsoo rau cov khoom hnyav tshem tawm. Lub siab ntau dhau los yog lub kaum sab xis sib tsoo tsis raug tuaj yeem tsim cov grooves sib sib zog nqus lossis cov dents ntawm qhov chaw ua haujlwm, ua rau tom qab ua tiav nyuaj dua.
Thaum tshav kub kub discoloration
Cov ntaub ntawv uas tsis tshua muaj thermal conductivity, xws li stainless hlau, yog rhiab heev rau cua sov. Yog tias cov khoom siv tsis zoo siv los yog kev sib tsoo nyob rau hauv ib cheeb tsam ntev dhau lawm, cov cua kub ntau dhau yuav ua rau muaj xim tsis zoo thiab tseem cuam tshuam rau thaj chaw ua haujlwm.
Tshem tawm qhov pores
Cov khoom pov thawj feem ntau muaj cov pores sab hauv, tshwj xeeb tshaj yog nyob ze ntawm qhov chaw. Cov pores no yog tsim thaum lub sij hawm casting thiab tej zaum yuav dhau los ua kev ntxhov siab concentration ntsiab lus thaum lub sij hawm kev pab cuam.
Thaum tshem tawm cov pores saum npoo, qhov tob hauv qhov pores yuav tshwm sim tom qab sib tsoo. Qhov no tsis yog tshwm sim los ntawm kev sib tsoo nws tus kheej tab sis los ntawm qhov tsis xws luag hauv cov khoom uas yuav tsum tau tshem tawm cov khoom lag luam ntxiv.
Ntau cov pits tshwm sim los ntawm cov nplua nuj abrasive ntau dhau
Kev siv cov nplej abrasive uas zoo heev thaum lub sij hawm ua kom zoo dua tuaj yeem ua rau cov txiaj ntsig tsis zoo. Es tsis txhob tshem tawm tag nrho cov tsis xws luag, cov nplej zoo tuaj yeem txhuam lawv thiab tawm cov kab noj hniav me me hauv qab ntawm qhov chaw, uas yuav dhau los ua cov ntsiab lus corrosion lossis tawg.
Plough marks tshwm sim los ntawm kev sib tsoo cov cuab yeej nruj heev
Cov cuab yeej nruj heev tuaj yeem tawm qhov sib sib zog nqus thiab nqaim ntawm qhov chaw. Cov cuab yeej sib tshooj tuaj yeem tsim cov profile tsis sib xws, ua rau nws nyuaj rau kev ua tiav tiav.
Txhawm rau tiv thaiv qhov tsis xws luag thiab txhim kho kev sib tsoo, peb qhov tseem ceeb yuav tsum tau txiav txim siab thaum xaiv cov khoom siv abrasive.
1. Xaiv cov khoom tsim nyog
Abrasive khoom yog feem ntau muaj xws li abrasive siv thiab sib tsoo discs. Txhawm rau tshem tawm cov teeb meem ntawm cov ntawv hlau, kev sib tsoo disc yog siv ntau zaus. Cov kev xaiv uas muaj xws li:
Hard Sib tsoo Discs
Cov kev sib tsoo nyuaj yog kev nyuaj siab -cov discs nruab nrab nrog cov khoom siv hluav taws xob uas tau muab faib rau hauv kev sib koom ua ke. Lawv cov qauv nruj muab lub peev xwm txiav muaj zog tab sis kuj tseem tuaj yeem tsim kev vibration muaj zog dua thaum ua haujlwm.
Yog tias tus neeg teb xov tooj tsis muaj kev paub dhau los, qhov tsis xws luag yuav nyob twj ywm lossis ua rau mob hnyav dua. Kev sib cuag lub kaum sab xis ntawm kwv yees li 30℃-45℃feem ntau pom zoo.
Fiber Sanding Discs
Fiber sanding discs tau siv dav vim tias lawv muab cov khoom lag luam tshem tawm siab, ua kom yooj yim, tuav tau yooj yim, thiab txhim khu kev qha tiav.
Lawv cov qauv sib xyaw ua ke nrog vulcanized fiber thaub qab, cov ntaub ntawv sib txuas, thiab cov nplej abrasive, tsim kom muaj kev sib tsoo yooj yim uas hloov tau zoo rau ntau qhov chaw. Lub kaum sab xis ntawm ib ncig ntawm 10℃-20℃pom zoo.
Flap Discs
Flap discs yog tsim los ntawm ntau daim ntaub abrasive flaps txuas rau lub nraub qaum, feem ntau yog fiberglass. Lawv muab kev co zoo nqus, tswj tau yooj yim dua, thiab kev sib tsoo smoother.
Piv nrog cov tsoos discs, nrov plig plawg discs tsim tsawg dua khawb tob, tab sis lawv cov kev ua haujlwm feem ntau qis dua. Kev kub siab ntau dhau tuaj yeem ua rau lub cev sib txuas thiab ua kom nrawm nrawm.
2. Xaiv hom Abrasive Grain Zoo
Cov ntaub ntawv sib txawv yuav tsum muaj cov yam ntxwv sib txawv ntawm cov nplej abrasive. Hardness thiab toughness yog lub ntsiab tseem ceeb uas txiav txim siab qhov kev xaiv raug.
Rau cov pa roj carbon steel thiab stainless hlau, aluminium oxide abrasive grain yog feem ntau xaiv vim nws cov kev ua tau zoo txiav thiab ua haujlwm ntev. Rau tooj liab, tooj dag, aluminium alloys, titanium alloys, thiab lwm yam tsis yog -ferrous cov ntaub ntawv, zirconia abrasive grain feem ntau yog ib qho kev xaiv zoo dua.
Rau kev thov sib tsoo daim ntawv thov, cov khoom kuj tseem siv silicon carbide, cubic boron nitride, los yog pob zeb diamond abrasive lis kom ua tau zoo dua ntawm cov ntaub ntawv tshwj xeeb xws li siab -lub zog steel thiab npib tsib xee-raws li alloys.
Ceramic Abrasive Grain Advantages
Ceramic abrasive grain muaj cov qauv microcrystalline tshwj xeeb uas tso cai rau kev puas tsuaj thaum sib tsoo. Qhov no tsis tu ncua nthuav tawm cov npoo tshiab thiab tswj xyuas kev ua tau zoo.
Nws cov txiaj ntsig tseem ceeb suav nrog:
Kev tshem tawm cov khoom sai dua ntawm cov hlau tsis muaj steel thiab siab -kub alloys.
Txo qhov sib tsoo kub thiab ua haujlwm ntev dua.
Txo cov cua sov los ntawm tus kheej - lubricating txheej.
Kev ua tau zoo dua ntawm cov khoom siv nrog thermal conductivity tsis zoo.
3. Tswj kev sib tsoo kub thiab Grit loj
Thaum tshav kub kub ntau dhau yog ib qho ntawm cov laj thawj tseem ceeb ntawm kev hloov xim ntawm qhov chaw thiab kev puas tsuaj. Yog li ntawd, xaiv qhov tseeb abrasive grain thiab grit loj yog qhov tseem ceeb rau kev ua tiav kev sib tsoo ruaj khov.
Tus lej grit qis dua muab qhov muaj peev xwm txiav tau zoo dua tab sis ua rau lub ntsej muag rougher tiav. Rau feem ntau daim ntawv thov, pib nrog grit qhov ntau thiab tsawg ntawm 20 thiab 40 yog pom zoo rau kev tshem tawm tsis xws luag, ua raws li nruab nrab los yog nplua grits los txhim kho nto zoo.
Dhau li ntawm grit loj, abrasive faib ceev thiab thaub qab hardness kuj cuam tshuam rau kev sib tsoo. Lower grain density tso cai rau txhua cov nplej abrasive nqa ntau lub zog, thaum lub zog rov qab tuaj yeem ua rau muaj kev vibration thiab txo qhov zoo.
Hauv kev xaus, kev sib tsoo ua tiav yog nyob ntawm kev nrhiav qhov sib npaug ntawm cov khoom lag luam, xaiv cov nplej abrasive, thiab grit loj. Kev xaiv cov qoob loo kom raug tsis yog tsuas yog pab tshem tawm qhov tsis xws luag tab sis kuj tseem txhim kho qhov zoo, txo qis kev ua haujlwm, thiab txuas ntxiv lub neej ntawm cov cuab yeej.
