Ubunjineli Bokuchaneka: Umngeni Wokwandisa Iiplatifomu ZeGranite

Umbuzo obonakala ulula wokuba ingaba ubungakanani buchaphazela ubunzima bolawulo oluchanekileyo kwiiplatifomu zegranite uhlala ufumana "ewe" oqondakalayo kodwa ongaphelelanga. Kwicandelo lokuvelisa oluchanekileyo kakhulu, apho iZHHIMG® isebenza khona, umahluko phakathi kokulawula ukuchaneka kwepleyiti yomphezulu wegranite encinci, enebhentshi engama-300 × 200 mm kunye nesiseko somatshini esikhulu sama-3000 × 2000 mm asikokubala nje kuphela; lutshintsho olusisiseko kubunzima bobunjineli, olufuna amaqhinga okuvelisa ahlukeneyo ngokupheleleyo, izibonelelo, kunye nobuchule.

Ukunyuka Okucacileyo Kwempazamo

Nangona amaqonga amancinci namakhulu kufuneka anamathele kwiinkcukacha ezingqongqo zokuthamba, umngeni wokugcina ukuchaneka kwejometri kulinganiswa ngokukhawuleza ngokobukhulu. Iimpazamo zeqonga elincinci zifumaneka kwindawo ethile kwaye kulula ukuzilungisa ngeendlela zendabuko zokuleqa ngesandla. Kwelinye icala, iqonga elikhulu lizisa iileya ezininzi zobunzima ezibangela umngeni kwanabavelisi abaphambili:

1. Umxhuzulane kunye nokuPhambuka: Isiseko segranite esingama-3000 × 2000 mm, esinobunzima beetoni ezininzi, sifumana ukuphambuka okukhulu kobunzima bomzimba waso kulo lonke ixesha laso. Ukuqikelela nokuhlawula olu tshintsho lwe-elastic ngexesha lenkqubo yokuleqa—nokuqinisekisa ukuba ukuthamba okufunekayo kufezekiswa phantsi komthwalo osebenzayo ekugqibeleni—kufuna uhlalutyo oluntsonkothileyo lwezinto ezilinganiselweyo (FEA) kunye neenkqubo zenkxaso ezikhethekileyo. Ubunzima obupheleleyo benza ukuba ukutshintshwa kwendawo kunye nokulinganisa kube nzima kakhulu.
2. IiGradients zoBushushu: Okukhona umthamo wegranite umkhulu, kokukhona kuthatha ixesha elide ukufikelela kumlinganiselo opheleleyo wobushushu. Kwanokutshintshatshintsha kobushushu okuncinci kumphezulu wesiseko esikhulu kudala iigradients zobushushu, nto leyo ebangela ukuba izinto zigobe kancinci. Ukuze i-ZHHIMG® iqinisekise ukuba i-nanometer-level flat, ezi zinto zinkulu kufuneka zicutshungulwe, zilinganiswe, kwaye zigcinwe kwiindawo ezikhethekileyo—ezifana neeworkshop zethu ezili-10,000 ㎡ ezilawulwa yimozulu—apho ukutshintshatshintsha kobushushu kulawulwa ngokuqinileyo kulo lonke umthamo wegranite.

Ukwenziwa kweMveliso kunye neMetroloji: Uvavanyo loMgangatho

Ubunzima busekelwe nzulu kwinkqubo yokuvelisa ngokwayo. Ukufezekisa ukuchaneka kokwenyani kwinqanaba elikhulu kufuna izixhobo kunye neziseko ezingundoqo ezinabantu abambalwa kushishino.

Kwipleyiti encinci engama-300 × 200 mm, ukulepha ngesandla ngobuchule kudla ngokwanela. Nangona kunjalo, kwiqonga elingama-3000 × 2000 mm, le nkqubo ifuna izixhobo zokugaya ze-CNC ezinomthamo omkhulu kakhulu (ezifana noomatshini bokugaya baseTaiwan Nanter beZHHIMG®, abakwaziyo ukuphatha ubude obungama-6000 mm) kunye nokukwazi ukuhambisa nokuphatha izinto ezinobunzima obufikelela kwiitoni ezili-100. Ubungakanani bezixhobo kufuneka buhambelane nobungakanani bemveliso.

Ngaphezu koko, i-metrology—isayensi yokulinganisa—iba nzima ngakumbi ngokwemvelo. Ukulinganisa ubucaba bepleyiti encinci kunokwenziwa ngokukhawuleza ngamanqanaba e-elektroniki. Ukulinganisa ubucaba beqonga elikhulu kufuna izixhobo eziphambili, ezikude ezifana neRenishaw Laser Interferometers kwaye kufuna ukuba yonke indawo engqongileyo ihlale izinzile ngokupheleleyo, into ejongwa zii-floors ezidampingiswa yi-ZHHIMG® kunye ne-anti-seismic trenches. Iimpazamo zokulinganisa kwisikali esincinci azinamsebenzi; kwisikali esikhulu, zinokudibanisa kwaye zingasebenzi yonke into.

Inxalenye Yomntu: Amava Abalulekile

Okokugqibela, izakhono zabantu ezifunekayo zahluke kakhulu. Iingcali zethu ezinamava, ezinamava angaphezu kweminyaka engama-30 okusebenzisa i-lapping ngesandla, zinokufikelela ngokuchanekileyo kwinqanaba le-nano kuzo zombini izikali. Nangona kunjalo, ukufikelela kweli nqanaba lokufana kumphezulu omkhulu we-6㎡ kufuna inqanaba lokunyamezela ngokomzimba, ukuhambelana, kunye nobuchule bendawo obudlula ubuchule obuqhelekileyo. Yile ndibaniselwano yeziseko zophuhliso ezikumgangatho wehlabathi kunye nobuchule bomntu obungenakuthelekiswa nanto ekugqibeleni obahlula umthengisi onokukwazi ukuphatha zombini ezincinci nezinkulu kakhulu.

Ukuqukumbela, ngelixa iqonga elincinci legranite livavanya ukuchaneka kwezinto kunye nobuchule, iqonga elikhulu livavanya ngokusisiseko yonke inkqubo yokuvelisa—ukusuka ekungqineni kwezinto kunye nokuzinza kwezixhobo ukuya kumandla oomatshini kunye namava anzulu eenjineli ezingabantu. Ukulinganiswa kobukhulu, ngokwenene, kukulinganiselwa komngeni wobunjineli.
