Granite slab nto xov tiav yuav tsum nruj kom ntseeg tau siab precision, siab stability, thiab kev ua tau zoo heev. Cov hauv qab no yog cov lus piav qhia ntxaws txog cov kev cai no:
I. Yam yuav tsum tau muaj
Defect-Free Deg: Qhov chaw ua haujlwm ntawm granite slab yuav tsum tsis muaj kab nrib pleb, dents, xoob kev ntxhib los mos, hnav cov cim, lossis lwm yam tsis xws luag uas tuaj yeem cuam tshuam rau nws cov kev ua tau zoo. Cov kev tsis zoo no cuam tshuam ncaj qha rau lub slab qhov tseeb thiab kev pabcuam lub neej.
Natural Streaks thiab Xim Spots: Ntuj, tsis yog khoom cuav streaks thiab xim xim tau tso cai rau saum npoo ntawm granite slab, tab sis lawv yuav tsum tsis txhob cuam tshuam rau tag nrho cov kev zoo nkauj lossis kev ua haujlwm ntawm cov slab.
2. Machining Accuracy Requirements
Flatness: Lub flatness ntawm granite slab qhov chaw ua hauj lwm yog ib qho tseem ceeb qhia ntawm machining raug. Nws yuav tsum ua kom tau raws li qhov yuav tsum tau ua kom muaj kev ruaj ntseg siab thaum lub sij hawm ntsuas thiab qhov chaw. Flatness feem ntau yog ntsuas siv cov cuab yeej ntsuas siab xws li interferometers thiab laser flatness meters.
Nto Roughness: Qhov saum npoo roughness ntawm granite slab qhov chaw ua hauj lwm kuj yog ib qho tseem ceeb qhia ntawm machining raug. Nws txiav txim siab qhov chaw sib cuag thiab kev sib txhuam ntawm cov slab thiab cov khoom ua haujlwm, yog li cuam tshuam rau kev ntsuas qhov tseeb thiab ruaj khov. Surface roughness yuav tsum tau tswj raws li tus nqi Ra, feem ntau yuav tsum muaj ntau yam ntawm 0.32 txog 0.63 μm. Tus nqi Ra rau sab saum npoo roughness yuav tsum tsawg dua 10 μm.
3. Cov txheej txheem thiab cov txheej txheem yuav tsum tau ua
Tshuab-txiav nto: txiav thiab zoo li tus siv lub voj voog, xuab zeb pom, los yog choj pom, uas ua rau ib tug rougher nto nrog pom lub tshuab-txiav cov cim. Txoj kev no yog tsim rau cov ntawv thov uas qhov precision nto tsis yog qhov tseem ceeb tshaj.
Matt tiav: Kev kho lub teeb polishing siv cov resin abrasives yog siv rau saum npoo, ua rau cov iav tsis tshua muaj gloss, feem ntau hauv qab 10 °. Txoj kev no haum rau cov ntawv thov uas glossiness tseem ceeb tab sis tsis tseem ceeb.
Polish tiav: Lub ntsej muag polished heev ua rau lub ntsej muag zoo nkauj. Txoj kev no yog tsim rau cov ntawv thov uas siab gloss thiab precision yuav tsum tau.
Lwm txoj kev ua, xws li flamed, litchi-burnished, thiab longan-burnished tiav, feem ntau yog siv rau cov hniav thiab beautification lub hom phiaj thiab tsis haum rau granite slabs uas yuav tsum tau high precision.
Thaum lub sij hawm machining txheej txheem, precision ntawm machining cov cuab yeej thiab cov txheej txheem tsis, xws li kev sib tsoo ceev, sib tsoo siab, thiab sib tsoo lub sij hawm, yuav tsum nruj me ntsis tswj xyuas kom meej tias cov nto zoo raws li qhov yuav tsum tau.
4. Tom qab ua tiav thiab soj ntsuam yuav tsum tau ua
Ntxuav thiab ziab: Tom qab machining, granite slab yuav tsum tau ntxuav kom huv si thiab qhuav kom tshem tawm cov av thiab ya raws, yog li tiv thaiv kev cuam tshuam ntawm kev ntsuas qhov tseeb thiab kev ua haujlwm.
Kev Tiv Thaiv Kev Kho Mob: Txhawm rau txhim kho huab cua tiv thaiv thiab kev pabcuam lub neej ntawm granite slab, nws yuav tsum tau kho nrog kev tiv thaiv kev kho mob. Feem ntau siv cov tshuaj tiv thaiv muaj xws li cov kuab tshuaj raws li cov kuab tshuaj thiab cov tshuaj tiv thaiv dej. Kev tiv thaiv kev kho mob yuav tsum tau ua rau ntawm qhov chaw huv thiab qhuav thiab nruj raws li cov lus qhia ntawm cov khoom.
Kev soj ntsuam thiab Kev Txais: Tom qab machining, granite slab yuav tsum tau ua tib zoo xyuas thiab lees txais. Kev tshuaj xyuas npog cov cim tseem ceeb xws li qhov tseeb qhov tseeb, flatness, thiab nto roughness. Kev lees txais yuav tsum nruj me ntsis ua raws li cov qauv thiab cov kev cai, kom ntseeg tau tias cov slab qhov zoo ua tau raws li tus qauv tsim thiab cov kev xav tau siv.
Hauv cov ntsiab lus, qhov yuav tsum tau ua rau granite slab nto ua haujlwm muaj ntau yam, suav nrog cov kev xav tau yooj yim, kev ua kom raug, cov txheej txheem ua thiab cov txheej txheem yuav tsum tau ua, thiab cov txheej txheem tom ntej thiab tshuaj xyuas. Cov kev cai no ua ke tsim qhov kev txiav txim siab zoo rau granite slab nto ua haujlwm, txiav txim siab nws qhov kev ua tau zoo thiab kev ruaj ntseg hauv kev ntsuas qhov tseeb thiab qhov chaw.
