Covxim av aluminium oxide sib tsoo logyog ib qho tseem ceeb tshaj plaws sib tsoo cov cuab yeej siv dav hauv kev lag luam machining. Nws qhov kev ua tau zoo nyob ntawm qhov tsis zoo ntawm cov khoom siv raw, tab sis kuj nyob ntawm qhov tseeb ntawm cov txheej txheem ntau lawm. Ib qhov zoo-tswj cov txheej txheem tsim khoom ua kom muaj kev sib tsoo ruaj khov, kev ua haujlwm ntev, thiab kev ruaj ntseg ruaj ntseg thaum ua haujlwm.
1. Kev xaiv raw khoom
Kev tsim cov xim av xim av aluminium oxide sib tsoo log pib nrog kev ua tib zoo xaiv cov khoom siv raw. Xim av aluminium oxide abrasive yog xaiv rau nws qhov siab hardness, toughness, thiab zoo heev hnav tsis kam, ua rau nws haum rau hnyav- daim ntaub ntawv sib tsoo. Tib lub sijhawm, tus neeg sawv cev sib txuas- xws li ceramic, resin, roj hmab, lossis hlau- raug xaiv raws li daim ntawv thov npaj. Qhov zoo thiab kev faib ua feem ntawm cov ntaub ntawv no ncaj qha cuam tshuam rau qhov kawg ntawm lub zog, hardness, thiab txiav kev ua tau zoo ntawm kev sib tsoo log.
2. Sib tov thiab sib sau
Tom qab xaiv cov ntaub ntawv, cov nplej abrasive thiab cov khoom sib txuas sib xyaw ua ke kom ntseeg tau tias muaj kev sib faib. Cov kauj ruam no yog qhov tseem ceeb vim tias kev sib xyaw tsis sib haum tuaj yeem ua rau kev sib tsoo tsis sib xws lossis kev ua haujlwm tsis zoo. Cov khoom sib xyaw yog ces nias rau hauv cov duab siv pwm nyob rau hauv kev tswj siab. At this stage, the preliminary structure of the brown aluminum oxide grinding wheel is formed, including its density and internal porosity, which are essential for chip removal and heat dissipation during grinding.
3. Qhuav thiab Calcining
Ib zaug tsim, lub log ntsuab sib tsoo ua tiav cov txheej txheem ziab kom tshem tawm cov dej noo ntau dhau thiab ua kom ruaj khov ntawm nws cov qauv. Tom qab ziab, lub log yog calcined los yog raug rho tawm haujlwm ntawm qhov kub thiab txias. Cov kauj ruam no ntxiv dag zog rau kev sib raug zoo ntawm cov nplej abrasive thiab cov binder, muab cov xim av aluminium oxide sib tsoo lub log nws qhov kawg txhua yam khoom. Qhov kub thiab lub sij hawm ntawm calcining yuav tsum tau tswj kom meej, raws li lawv txiav txim siab lub log hardness, lub zog, thiab durability.
4. Ua tiav thiab tshuaj xyuas
Tom qab calcining, lub log sib tsoo yuav raug ua kom tiav cov txheej txheem xws li shaping, ntsuas, thiab kho qhov chaw kom ntseeg tau tias nws ua tau raws li qhov yuav tsum tau muaj qhov ntev thiab geometric. Txhua lub xim av aluminium oxide sib tsoo lub log yuav tsum dhau qhov kev tshuaj xyuas nruj, suav nrog kev kuaj pom thiab kuaj kev ua haujlwm, kom lav qhov sib xws thiab kev ntseeg tau. Cov kev tshuaj xyuas no pab tiv thaiv qhov tsis xws luag uas tuaj yeem cuam tshuam kev sib tsoo kom raug lossis kev nyab xeeb.
5. Kev kuaj kev nyab xeeb thiab hnav khaub ncaws
Ua ntej muab tso rau hauv kev siv, cov xim av aluminium oxide sib tsoo lub log yuav tsum tau kuaj xyuas kev nyab xeeb, xws li kev sib hloov cov kev ntsuam xyuas kom ntseeg tau tias nws tuaj yeem tiv taus kev ua haujlwm siab yam tsis ua haujlwm. Thaum siv tiag tiag, lub log sib tsoo yuav maj mam poob nws qhov ntse thiab cov duab geometry, yog li kev hnav khaub ncaws tsis tu ncua yuav tsum tau rov qab nws cov peev xwm txiav thiab tswj kev ua haujlwm zoo.
Cov txheej txheem tsim cov xim av xim av aluminium oxide sib tsoo log muaj ntau yam meej thiab tswj cov kauj ruam, los ntawm kev xaiv cov khoom siv raw mus rau qhov kawg tshuaj ntsuam xyuas. Txhua theem ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab lub log kev ua haujlwm, kev nyab xeeb, thiab kev pabcuam lub neej. Los ntawm kev ua kom zoo ntawm cov txheej txheem tsim khoom, cov neeg siv tuaj yeem ua tiav kev sib tsoo ntau dua, zoo dua saum npoo zoo, thiab txhim kho tag nrho cov khoom tsim tau.
