Emkhakheni we-metrology enembile kakhulu kanye nokukhiqizwa okunezinzuzo ezinkulu—kusukela ekuhlolweni kwezindiza kuya ekukhiqizweni kwesikhunta—i-Ubuso beGranite obuqondileIpuleti lisebenza njengesisekelo seqiniso elinobukhulu. Nakuba ukuthamba kwalo kuthola ukunakwa okukhulu, umbuzo oyisisekelo wobukhulu ubaluleke ngokulinganayo, usebenza njengokuguquguquka okuyisisekelo kobunjiniyela okuqondisa ukusebenza kwepulatifomu ngaphansi komthwalo kanye nokuqina kwayo kwejometri kwesikhathi eside.
Ubukhulu beplatifomu yegranite abukhethwa ngokungahleliwe; buyisilinganiso esibalwe ngokucophelela esithathwe ezimisweni zobunjiniyela eziqinile, ezixhumanisa ngqo namandla okuthwala umthwalo wepuleti, ukuqina, kanye nekhono lalo lokusebenza njengendiza yedatha engaguquki ngempela. Ukuqonda lobu budlelwano kubalulekile konjiniyela nabaphathi bekhwalithi abahlose ukwenza ngcono izinqubo zabo zokuhlola nokuhlanganisa.
I-Fiziksi Yokuzinza: Kungani Ubukhulu Bubalulekile
Inhloso eyinhloko yeGranite Surface Plate ukumelana nokuphambuka. Lapho izinsimbi zokulinganisa, izinto ezisetshenziswayo, kanye nezingxenye ezisindayo kubekwa phezu kobuso, amandla adonsela phansi anamandla okuwa phansi. Uma ipuleti lingenabo ubukhulu obanele, lizogoba kancane, lenze amaphutha ejiyometri angamukeleki ekulinganisweni.
Lobu budlelwano bulawulwa yizimiso zemishini yezinto ezibonakalayo, lapho ukuqina kweslabhu kuhlobene khona kakhulu nobukhulu bayo.
-
Ukumelana Nokuphambuka (Ukuqina): Ukuqina kwensimbi noma ipuleti kuhlobene ne-cube yobukhulu bayo (I ∝ h³), lapho i-$I$ ingumzuzu wendawo we-inertia kanti i-h ingubukhulu. Lokhu kusho ukuthi ukuphinda kabili ubukhulu bepulatifomu ye-granite kwandisa ukuqina kwayo ngesilinganiso esingu-8. Kwi-ZHHIMG®'s High-Density Black Granite (cishe ama-3100 kg/m³), lokhu kuqina kwezinto ezibonakalayo kuyakhuliswa, okuholela ekumelaneni okuphezulu kokuguquguquka kwe-elastic ngaphansi komthwalo.

Ukwanda Komthamo Wokuthwala Umthwalo: Ngenxa yokuthi ukuqina kuhlotshaniswa kakhulu nobukhulu, ukunquma ubukhulu obufanele kuyinselele eyinhloko yobunjiniyela ekuqinisekiseni amandla anele okuthwala umthwalo. Kumapuleti amakhulu, anzima—njengalawo asetshenziswa njenge-CMM Base noma ukuhlola izingxenye ezinkulu zezindiza ezinembe kakhulu—ubukhulu kumele bube banele ukuqinisekisa ukuthi umthwalo omkhulu olindelekile ubangela ukuphambuka okungaphansi kakhulu kokubekezelelana kokulinganisa okubucayi (ukunemba kwe-sub-micron).
-
Isisindo Sokudambisa Ukudlidliza: Ngenkathi isakhiwo sangaphakathi se-granite sinikeza ukudambisa ukudlidliza okuhle kakhulu, ipuleti elijiyile lengeza isisindo esikhulu. Lokhu kuqina okwandisiwe kunciphisa imvamisa yemvelo yepuleti, kuyisusa kumaza okudlidliza okusebenza kanye nendawo (i-HVAC, ithrafikhi yezinyawo). Lokhu kuhlukaniswa okungenamsebenzi kubalulekile ezinhlelweni zokusebenza ezidinga ukumetrology okuzinzile, okungenamsindo.
Ukunqunywa Kobunjiniyela: Ukubala Ubukhulu Obudingekayo
Inqubo yokunquma ukujiya okufanele ihilela ukuhlaziywa okuningiliziwe kwezidingo ezithile zesicelo:
-
Ukubekezelela Ukusetshenziswa (Ibanga Lokunemba): Isici sokuqala nesibaluleke kakhulu izinga lokunemba elidingekayo lepuleti (isb., Ibanga B, A, AA, noma Ibanga 00 elidingakalayo). Ukubekezelelana okuqinile kudinga ukuqina okuphezulu ukuze kugcinwe ukuthamba ngaphansi kwazo zonke izimo, okudinga ukujiya okukhulu.
-
Usayizi kanye ne-Span: Amapuleti amakhulu angaphezulu adinga ukujiya okukhulu ngokulinganayo ukuze abuyisele ububanzi obungasekelwa. Ipuleti elikhulu elinobukhulu obunganele lizogoba ngaphansi kwesisindo salo, ngisho noma kungekho umthwalo wangaphandle. Ikhono le-ZHHIMG® lokukhiqiza Izakhiwo Zomshini We-Granite Ezinkulu ezifika kumamitha angu-20 ubude lisekelwa ubuchwepheshe bobunjiniyela obubala ngokunembile ubukhulu obudingekayo be-span enkulu kangaka.
-
Ukusatshalaliswa kanye Nomthwalo Omkhulu: Onjiniyela kumele babhale isisindo esiphelele semishini yokulinganisa, izinto ezisetshenziswayo, kanye nengxenye ngokwayo. Umklamo kumele uphathe umthwalo omkhulu ogxilile (isb., ikholomu ye-CMM yendawo) ngaphandle kokudlula ukuphambuka okuphezulu okuvunyelwe okuchazwe yizindinganiso zomhlaba wonke (ASME B89.3.7, DIN 876).
Kupuleti elijwayelekile lezentengiselwano, amashadi okujiya avame ukusetshenziswa. Kodwa-ke, kuma-Granite Components noma ama-Granite Machine Structures aklanywe ngokwezifiso lapho ipuleti kufanele lisekele imishini ebucayi kakhulu njenge-air bearings noma ama-laser interferometers, ukuhlaziywa kwe-full finite element (FEA) kuvame ukusetshenziswa ukuze kuboniswe ukucindezeleka kanye nokuphambuka ngokunembile, okuqinisekisa ukuzinza kwejometri okudingekayo.
Ukuzinza Okungaphezu Komthwalo: Isici Sokushisa
Ubudlelwano phakathi kobukhulu nokuqina budlulela ngale kokuphambuka komshini endaweni yokushisa.
-
I-Thermal Inertia: Ipulatifomu ebanzi kakhulu ine-inertia enkulu yokushisa. Lokhu kusho ukuthi kuthatha isikhathi eside kakhulu ukuthi ukushintshashintsha kwezinga lokushisa elizungezile kungene ku-granite futhi kuthinte izinga lokushisa eliyinhloko. Njengoba i-Coefficient of Thermal Expansion (CTE) ephansi ye-granite isivele iyinzuzo enkulu kunensimbi, i-inertia eyengeziwe yokushisa evela ekujikeni iqinisekisa ukuzinza okuphezulu kwesikhathi eside, okubalulekile ekusebenzeni okwenziwa isikhathi eside endaweni yelebhu. Ngisho nangaphakathi kwe-10,000 m² Constant Temperature and Humidity Workshop, lokhu kuzinza kwangaphakathi kuyathandwa.
-
Ama-Gradients Okucindezeleka Ancishisiwe: Isisindo esikhulu sisiza ukunciphisa ama-gradients okushisa kwangaphakathi, sivimbele izingxenye ezahlukene zepuleti ukuthi zande noma zinciphe ngamazinga ahlukene. Lokhu kunciphisa ingozi yokuqhekeka okuncane okungalimaza i-Nanometer-Level Precision efinyelelwa ngenqubo yethu eqinile yokubopha.
I-ZHHIMG®: Ubukhulu Bobunjiniyela Bokusebenza Okungaguquki
Kwa-ZHHUI Group, ukunqunywa kobukhulu kuyisinqumo esibalulekile sobunjiniyela esiqhutshwa ukuzibophezela ezindinganisweni eziphakeme kakhulu zomhlaba wonke. Sisebenzisa ulwazi lwethu nge-ZHHIMG® Black Granite yethu—ekhethwe ngokukhethekile ngenxa yobuningi bayo obuphezulu—ukwakha ipuleti elincane kakhulu elisedlula ukuzinza kanye nomthamo wokuthwala umthwalo odingekayo ngokwezincazelo zeklayenti.
Umqondo wethu wokukhiqiza, “Ibhizinisi elinembile alikwazi ukuba nzima kakhulu,” usho ukuthi singalimazi ukuzinza ngenxa yezindleko. Kungakhathaliseki ukuthi sakha i-Granite Measuring Ruler ejwayelekile noma i-Granite Gantry Base eyinkimbinkimbi, enamathani amaningi, ubukhulu obuklanywe ngobunjiniyela buyisiqinisekiso sokuqina, okuqinisekisa ukuthi umkhiqizo wokugcina oqinisekisiwe unikeza indiza engaguquki, engenankomba efunwa yizimboni eziqine kakhulu emhlabeni.
