Kwicandelo le-metrology echanekileyo kakhulu kunye nokuveliswa kwezinto ezibaluleke kakhulu—ukusuka ekuhlolweni kweenqwelo-moya ukuya ekuvelisweni kwe-mold—Umphezulu weGranite ochanekileyoIpleyiti isebenza njengesiseko senyaniso enobukhulu. Nangona ukuba tyaba komphezulu wayo kuthathelwa ingqalelo kakhulu, umbuzo osisiseko wobukhulu ubaluleke ngokulinganayo, usebenza njengotshintsho olusisiseko lobunjineli olulawula ukusebenza kweqonga phantsi komthwalo kunye nokuzinza kwalo kwexesha elide.
Ubukhulu beqonga legranite abukhethwa ngokungacwangciswanga; bubungakanani obubalwe ngononophelo obuvela kwimigaqo yobunjineli engqongqo, edibanisa ngokuthe ngqo nomthamo weplate wokuthwala umthwalo, ubulukhuni, kunye nokukwazi kwayo ukusebenza njenge-datum plane engagungqiyo. Ukuqonda olu lwalamano kubalulekile kwiinjineli kunye nabaphathi bomgangatho abajonge ukuphucula iinkqubo zabo zokuhlola kunye nokuhlanganisa.
Ifiziksi Yozinzo: Kutheni Ubunzima Bubalulekile
Injongo ephambili yeGranite Surface Plate kukumelana nokuphambuka. Xa izixhobo zokulinganisa, izixhobo, kunye nezinto ezinzima zibekwe phezu komphezulu, umxhuzulane unamandla okuhla. Ukuba ipleyiti ayinabo ubukhulu obaneleyo, iya kugoba kancinci, ize yenze iimpazamo zejometri ezingamkelekanga kumlinganiselo.
Olu lwalamano lulawulwa yimigaqo yezinto zokwakha, apho ukuqina kweslab kunxulumene kakhulu nobukhulu bayo.
-
Ukuxhathisa ukuphambuka (Ukuqina): Ukuqina kwe-beam okanye ipleyiti kunxulumene ne-cube yobukhulu bayo (I ∝ h³), apho i-$I$ yindawo ye-inertia kwaye i-h bubukhulu. Oku kuthetha ukuba ukuphinda kabini ubukhulu beqonga le-granite kwandisa ukuqina kwayo nge-factor yesibhozo. Kwi-ZHHIMG®'s High-Density Black Granite (malunga ne-3100 kg/m³), obu bunzima bezinto ezibonakalayo buyandiswa, nto leyo ebangela ukuxhathisa okuphezulu kwi-elastic deformation phantsi komthwalo.

Ukwanda koMthamo wokuthwala imithwalo: Ngenxa yokuba ukuqina kunxulunyaniswa nobukhulu, ukumisela ubukhulu obufanelekileyo yeyona ngxaki iphambili yobunjineli ekuqinisekiseni ubungakanani obaneleyo bokuthwala imithwalo. Kwiipleyiti ezinkulu, ezinobunzima—ezifana nezo zisetyenziswa njengeSiseko seCMM okanye ekuhloleni iindawo ezinkulu zeenqwelo-moya ezichanekileyo kakhulu—ubukhulu kufuneka banele ukuqinisekisa ukuba umthwalo ophezulu olindelekileyo ubangela ukuphambuka okungaphantsi kakhulu kokunyamezelana kokulinganisa okubalulekileyo (ukuchaneka kwe-sub-micron).
-
Ubunzima bokuDambisa ukungcangcazela: Nangona ulwakhiwo lwangaphakathi lwegranite lubonelela ngokudambisa ukungcangcazela okugqwesileyo, ipleyiti etyebileyo yongeza ubunzima obukhulu. Olu bunzima buyandayo lunciphisa ubuninzi bendalo bepleyiti, buyisusa kwiifrikhwensi zokungcangcazela okuqhelekileyo kokusebenza kunye nokusingqongileyo (i-HVAC, ukuhamba ngeenyawo). Olu hluko lubalulekile kwizicelo ezifuna i-metrology ezinzileyo, engenangxolo.
Ukuqinisekiswa koBunjineli: Ukubala Ubukhulu obufunekayo
Inkqubo yokumisela ubukhulu obufanelekileyo ibandakanya uhlalutyo oluneenkcukacha lweemfuno ezithile zesicelo:
-
Ukunyamezela Ukusetyenziswa (Udidi Lokuchaneka): Into yokuqala neyona ibalulekileyo kudidi lokuchaneka olufunekayo lwepleyiti (umz., Udidi B, A, AA, okanye Udidi 00 olufuna ukuqina). Ukunyamezelana okuqinileyo kufuna ukuqina okuphezulu ukuze kugcinwe ukuthe tyaba phantsi kwazo zonke iimeko, nto leyo ebangela ukuba kube nobukhulu obukhulu.
-
Ubukhulu kunye nobubanzi: Iipleyiti ezinkulu zomphezulu zifuna ubukhulu obukhulu ngokulinganayo ukuze zihlawulele ububanzi obungaxhaswayo. Ipleyiti enkulu enobukhulu obunganelanga iya kutshona phantsi kobunzima bayo, nokuba akukho mthwalo wangaphandle. Amandla e-ZHHIMG® okwenza iiMonolithic Granite Machine Structures ukuya kuthi ga kwiimitha ezingama-20 ubude axhaswa bubuchule bobunjineli obubala ngokuchanekileyo ubukhulu obufunekayo kwiindawo ezinkulu kangaka.
-
Ukusasazwa kunye nomthwalo ophezulu: Iinjineli kufuneka ziqwalasele ubunzima obupheleleyo bezixhobo zokulinganisa, izixhobo, kunye nenxalenye ngokwayo. Uyilo kufuneka luphathe umthwalo ophezulu oxinanisiweyo (umz., ikholamu yeCMM yendawo) ngaphandle kokudlula ukuphambuka okuphezulu okuvumelekileyo okuchazwe yimigangatho yamazwe ngamazwe (ASME B89.3.7, DIN 876).
Kwipleyiti eqhelekileyo yorhwebo, kusetyenziswa iitshati zobukhulu. Nangona kunjalo, kwiinxalenye zeGranite ezenziwe ngokwezifiso okanye kwiZakhiwo zoMatshini weGranite apho ipleyiti kufuneka ixhase izixhobo ezinobuthathaka kakhulu ezifana neebheringi zomoya okanye ii-interferometer ze-laser, uhlalutyo olupheleleyo lwezinto ezilinganiselweyo (i-FEA) ludla ngokusetyenziswa ukubonisa uxinzelelo kunye nokuphambuka ngokuchanekileyo, okuqinisekisa uzinzo olufunekayo lwejometri.
Uzinzo olungaphaya komthwalo: I-Thermal Factor
Ubudlelwane phakathi kobukhulu kunye nozinzo budlulela ngaphaya kokuphambuka koomatshini ukuya kwindawo yobushushu.
-
I-Thermal Inertia: Iqonga elityebileyo line-thermal inertia enkulu. Oku kuthetha ukuba kuthatha ixesha elide kakhulu ukuba ukuguquguquka kobushushu obuphakathi kungene kwi-granite kwaye kuchaphazele ubushushu bayo obuphakathi. Ngenxa yokuba i-Coefficient of Thermal Expansion (CTE) ephantsi ye-granite sele inenzuzo enkulu kunentsimbi, i-thermal inertia eyongezelelweyo evela kubukhulu iqinisekisa uzinzo oluphezulu lwexesha elide, olubalulekileyo kwimisebenzi eyenziwa ixesha elide kwindawo yelabhoratri. Nokuba ngaphakathi kwi-10,000 m² Constant Temperature and Humidity Workshop, olu zinzo lwangaphakathi luyathandwa.
-
IiGradients zoXinzelelo eziNciphisiweyo: Ubunzima obukhulu bunceda ekunciphiseni iigradients zobushushu bangaphakathi, nto leyo ethintela iindawo ezahlukeneyo zepleyiti ukuba zingakhuli okanye zinciphe ngamanani ahlukeneyo. Oku kunciphisa umngcipheko we-warpage encinci enokuphazamisa i-Nanometer-Level Precision efunyenwe ngenkqubo yethu enzima yokuleqa.
I-ZHHIMG®: Ubukhulu bobuNjineli bokusebenza ngokungagungqiyo
Kwi-ZHHUI Group, ukumisela ubukhulu sisigqibo esibalulekileyo sobunjineli esiqhutywa kukuzinikela kwimigangatho ephezulu yamazwe ngamazwe. Sisebenzisa ulwazi lwethu lwe-ZHHIMG® Black Granite yethu—ekhethwe ngokukodwa ngenxa yoxinano lwayo oluphezulu—ukwenza uyilo lwepleyiti encinci kakhulu edlula uzinzo kunye nomthamo wokuthwala umthwalo ofunekayo ngokweenkcazo zomthengi.
Ingcamango yethu yokuvelisa, ethi “Ishishini elichanekileyo alinakuba nzima kakhulu,” iyalela ukuba singayibeki emngciphekweni uzinzo ngenxa yeendleko. Nokuba senza iGranite Measuring Ruler eqhelekileyo okanye iGranite Gantry Base eyinkimbinkimbi, enetoni ezininzi, ubukhulu obuyilwe ngobunjineli buqinisekisa uzinzo, okuqinisekisa ukuba imveliso yokugqibela eqinisekisiweyo inika umgangatho ongagungqiyo, ongenareferensi ofunwa ngamashishini anzima kakhulu kwihlabathi.
