Ipuleti elingaphezulu le-granite elifundeka ngokuthi “Ibanga 00” esitifiketini salo, ngokombono, kufanele lishintshelane nanoma yiliphi elinye ipuleti leBanga 00 emakethe. Empeleni, onjiniyela be-QC bayazi ukuthi lokhu akulona iqiniso ngaso sonke isikhathi. Amapuleti amabili angaba nezitifiketi ezifanayo zokusicaba futhi aqhubeke nokuziphatha ngendlela ehlukile empilweni yenkonzo yeminyaka emibili — elinye libambe ukulinganiswa kwalo, elinye liphuma ekubekezeleleni ngokushesha kunokulindelekile. Abathengi abaguquguqukayo abavame ukungakunaki akuyona inqubo yokugaya. Yizinto zokusetshenziswa ngokwazo.
Lena inkinga eqhubekayo, engaxoxwa kakhulu ku-ithuluzi lokulinganisa i-graniteuchungechunge lokuhlinzeka: imabula enobukhulu obuphansi, eqoshwe futhi yaqedwa ukuze ibukeke ingahlukaniseki ne-granite emnyama yangempela, ivame ukuthengiswa ngaphansi kohlu olujwayelekile lwe-"granite surface plate" noma "granite square ruler". Kumthengi oqhathanisa izingcaphuno ephepheni le-spec, umehluko awubonakali kuze kube yilapho ingxenye isivele isebenza. Ukuqonda ukuthi yikuphi ubuningi obukutshelayo ngempela ngethuluzi lokulinganisa i-granite - nokuthi ungaliqinisekisa kanjani - kungenye yezinyathelo ezisebenzayo zokuzikhandla ezitholakalayo ngaphambi kokuba kubekwe i-oda lokuthenga.
Kungani Ubuningi Buyimpahla Ebikezela Konke Okunye
Ubuningi akuyona nje inombolo ephepheni ledatha lezinto ezibonakalayo. Ezintweni ezisetshenziswa esikhundleni se-granite ne-granite, iyi-proxy ethembekile yesakhiwo sangaphakathi sekristalu esinquma ukuqina, ukumelana nokuguguleka, kanye nokuzinza kobukhulu besikhathi eside.
Lokho Okulethwa Yi-High-Density Black Granite Ngempela
I-granite emnyama yangempela enobukhulu obuphezulu, engaba ngu-3,100 kg/m³, iphakeme kakhulu kunobukhulu obuvame ukuhlotshaniswa nezinhlobo ze-granite zemabula noma zezinga eliphansi ezivame ukufakwa ohlwini lwesabelomali. Lowo mehluko wobukhulu uhumusha ube yizikhala zokusebenza ezilinganiswayo:
- • Ukuqina okuphezulu nokuqina — i-granite eqine kakhulu imelana nokuphambuka okuncane ngaphansi komthwalo, okubaluleke ngqo kumapuleti angaphezulu kanye nemiphetho eqondile esetshenziswa njengedathamu ye-zero-reference
- • Ukumelana nokuguguleka okungcono — isakhiwo esiqinile sekristalu simelana nokuguguleka kobuso ngenxa yokuxhumana okuphindaphindiwe kweprobe, ukushelela kwe-gauge block, kanye nokuphathwa kwezingxenye zomsebenzi
- • Ukubhoboka okuphansi — kunciphisa ukumuncwa komswakama, okuyinto ebalulekile ngoba umswakama omuncwayo ungabangela ukuvuvukala okunobukhulu obuncane kanye nokufundwa okungalingani ezindaweni ezinomswakama
- • Ukugcinwa okuthuthukisiwe kokuthamba kwesikhathi eside — izinto ezixineneyo azikwazi ukukhukhuleka kancane kancane noma ukuqina okungasusa ipuleti kancane kancane ebangeni layo eliqinisekisiwe eminyakeni eminingi yokusetshenziswa
I-marble, ngokuphambene, ngokuvamile inesakhiwo sekristalu esiqinile nesiguquguqukayo, ukuminyana okuphansi, kanye nokuvuleka okuphezulu — izakhiwo ezenza kube lula futhi kushibhile ukumba nokuqeda, kodwa ezingafaneleki kangako ukugcina ukubekezelelana kwe-sub-micron isikhathi eside.
Indlela Ubuningi Obuhlobene Ngayo Nokukala I-DIN 876 Flatness
I-DIN 876 — indinganiso ebhekiswa kakhulu ekusithekeni kwepuleti lobuso be-granite — ichaza amazinga amane okubekezelelana (00, 0, 1, 2), ngalinye lichaza ukuphambuka okuphezulu okuvunyelwe kokusithena ngokusekelwe endaweni yobuso bepuleti. Lokho i-DIN 876 engakusho ngokuqondile ubuningi noma ukwakheka kwezinto eziyisisekelo. Yingakho amapuleti amabili engaba negama elithi “Ibanga 00” ngenkathi ehluka kakhulu ezintweni ezingaphansi komhlabathi — izinga liqinisekisa ukusithena ngesikhathi sokuhlolwa, hhayi ikhono lesikhathi eside lezinto lokugcina lokho kusithena.
Kubathengi, lokhu kusho ukuthi isitifiketi se-DIN 876 kufanele siphathwe njengendawo yedatha edingekayo kodwa enganele. Ukusihlanganisa nencazelo yobuningi bezinto eziqinisekisiwe kunikeza isithombe esiphelele kakhulu sempilo yesevisi elindelekile.
Indlela Yokuqinisekisa Ubuningi beGranite Ngaphambi Kokuzibophezela ku-oda Lokuthenga
Izimangalo zobuningi ephepheni lemininingwane kulula ukuzisho futhi, ngeshwa, aziqinisekiswa njalo ngokuzimela ngaphambi kokuthunyelwa. Izindlela ezimbalwa zokuqinisekisa ezisebenzayo:
Cela Idatha Yokuhlolwa Kobungqingili Benkampani Yesithathu noma Yangaphakathi
- • Cela abahlinzeki ngemiphumela yangempela yobuningi obulinganisiwe (ngokusebenzisa indlela yokufuduka kwamanzi/indlela ye-Archimedes) kusuka eqenjini lezinto ezithile, hhayi isilinganiso semboni ejwayelekile
- • Lapho kungenzeka khona, cela isampula encane yezinto ezibonakalayo ukuze kuqinisekiswe ilebhu ngokuzimela ngaphambi kokuzibophezela ku-oda elikhulu.
- • Hlola ubuningi obushiwo ngumhlinzeki ngokuqhathanisa nobubanzi bokubhekisela obaziwayo begranite emnyama yangempela — amanani angaphansi kakhulu kuka-2,700–2,800 kg/m³ qinisekisa ukuhlolisiswa okuseduze.
Hlola Ingqalasizinda Yokulinganisa Yomhlinzeki
Umkhiqizi ozimisele ngobuqotho bezinto ezibonakalayo uvame ukutshala imali engqalasizinda yokulinganisa ukuze asekele lokhu:
- • Imishini yokulinganisa efana nama-laser interferometer, amazinga kagesi, kanye nama-inductive displacement gauges, kanye nezitifiketi ezingalandelelwa esikhungweni sikazwelonke se-metrology.
- • Izindawo zokuhlola ezilawulwa amazinga okushisa nomswakama, njengoba izilinganiso zokuthamba ezithathwe ekamelweni elingalawulwayo ziletha ukuhlukahluka kwazo
- • Imininingwane yemishini yokugaya ebhalwe phansi (isb., ama-grinder aphezulu anefomethi enkulu angakwazi ukucubungula ubude obude), okuhambisana nekhono lokubamba njalo ukubekezelelana okuqinile kumapuleti amakhulu.
Izigaba Zamathuluzi Okulinganisa Avamile Lapho Ubuningi Bubaluleke Kakhulu
- • Amapuleti ongaphezulu e-granite — asetshenziswa njengezinkomba eziyinhloko; ubuningi buthinta ngqo ukugcinwa kokuthamba kwesikhathi eside
- • Abalawuli abaqondile be-granite kanye nabalawuli besikwele — izinkomba zokuhlanganisa nokuqondanisa lapho izindaba ziqinile khona
- • Amabhulokhi e-V e-granite kanye nama-parallel — imithwalo yokuxhumana ephindaphindwayo kanye ne-clamping yenza ukumelana nokuguguleka kube yinto ebaluleke kakhulu
- • Izingxenye zokuthwala umoya we-granite — ukuqina kobuso ezingeni le-nanometer kuncike kakhulu ekwakhiweni kwezinto zangaphakathi ezifanayo
Kusho Ukuthi Lokhu Kusho Ukuthini Ngeqembu Le-QC Namaqembu Okuthenga
Akukho kulokhu okuhloswe ngakho ukuphakamisa ukuthi wonke amathuluzi e-granite ashibhile awafaneleki — ngenhloso evamile, ukusetshenziswa okungabalulekile kangako, ukuthengiselana kokubekezelelana nezindleko kungaba yinto enengqondo ngokuphelele. Inkinga iwukubiza kabi amalebula — imabula noma itshe elinobukhulu obuphansi elithengiswa ngaphandle kokudalulwa njengelilingana ne-granite emnyama enobukhulu obuphezulu, ehloselwe abathengi abangenayo indlela elula yokuqinisekisa isimangalo ngaphambi kokuthenga.
Kuzinhlelo zokusebenza lapho ithuluzi lokulinganisa lisebenza njengereferensi yokulinganisa, i-assembly datum, noma i-fixture yesikhathi eside yokukhiqiza, ecela idatha yobuningi obuqinisekisiwe kanye ne-DIN 876 (noma i-JIS, GB, ASME, BS 817-1983 efanayo, noma i-GOST 10905) isitifiketi sokuthamba siyisinyathelo sokuqinisekisa esingabizi kakhulu nesinenani eliphezulu. Kuthatha i-imeyili eyodwa eyengeziwe enqubweni ye-RFQ futhi kunganciphisa ngokunenjongo ingozi yokukhukhuleka okungalindelekile izinyanga noma iminyaka ngemva kokufakwa.
Isiphetho
Isitifiketi sokuthamba sikutshela ukuthi ithuluzi lokulinganisa i-granite lenze kanjani ngosuku elihlolwe ngalo. Ubuningi bezinto ezibonakalayo bukutshela ukuthi kungenzeka kangakanani ukuthi liqhubeke lifinyelele lelo banga lesibili, lesihlanu, noma leminyaka eyishumi kamuva. Konjiniyela be-QC kanye namaqembu okuthenga achaza amapuleti obuso be-granite, ama-ruler, noma amathuluzi okulinganisa ngokunemba, womabili amaphuzu edatha abalulekile - futhi akekho kuwo okufanele athathwe ngokholo ngaphandle kwemibhalo esekelayo.
I-ZHHIMG ikhiqiza amathuluzi okulinganisa i-granite enembile kanye nezingxenye zayo kusukela ku-granite emnyama enobukhulu obuphezulu (≈3,100 kg/m³), ehlolwe ngokuhambisana ne-DIN 876 kanye nezindinganiso ezifanayo zomhlaba wonke zokuthamba, kanye nokuhlolwa okulandelelwa yimishini yokulinganisa eqinisekisiwe. Abafundi abahlola imininingwane yezinto zephrojekthi ezayo bamukelekile ukucela imibhalo yobukhulu kanye nobukhulu ku-www.zhhimg.com.
