Ngaba iiPlatifomu ezichanekileyo zeGranite zineMiphawu yoMphezulu?

Xa ugunyazisa iqonga lokuchaneka kwegranite kwi-high-stakes metrology okanye indibano, abathengi bahlala bebuza: ngaba singakwazi ukwenza ngokwezifiso umphezulu kunye nokumakishwa-okufana nemigca yokulungelelanisa, iipateni zegridi, okanye iindawo ezithile zokubhekisela? Impendulo, evela kumenzi we-ultra-precision efana ne-ZHHIMG®, ngu-ewe oqinisekileyo, kodwa ukuphunyezwa kwezi mpawu kubugcisa obufihlakeleyo obufuna ubuchule bokuqinisekisa ukuba ukumakishwa kuyaphucula, kunokuba kuthotyelwe, ukuchaneka okuphambili kweqonga.

Injongo yoPhawu oluchanekileyo lweempawu

Kwiipleyiti zomgangatho wegranite ezisemgangathweni okanye iziseko zoomatshini, eyona njongo iphambili kukufikelela olona phawu luphezulu lunokwenzeka kunye nokuzinza kwejometri. Nangona kunjalo, kwizicelo ezinje ngeejigi zendibano ezinkulu, izikhululo zokulinganisa, okanye ukuseta uhlolo lwezandla, izixhobo ezibonwayo nezomzimba ziyimfuneko. Iimpawu zomphezulu zisebenza imisebenzi emininzi ebalulekileyo:

1. Izikhokelo zoLungelelwaniso: Ukubonelela ngokukhawuleza, imigca yesalathiso ebonwayo yokumiswa ngokurhabaxa kwezixhobo okanye iinxalenye ngaphambi kokubandakanya izigaba zohlengahlengiso oluncinci.
2. IiNkqubo zoLungelelaniso: Ukuseka igridi ecacileyo, yokuqala yolungelelwaniso (umzekelo, ii-axes ze-XY) ezinokulandeleka ukuya kwindawo esembindini okanye kumda wedatum.
3. Iindawo zokungaHanjwa: Iindawo zokumakisha apho izixhobo akufanele zibekwe ukuze kugcinwe ukulingana okanye ukuthintela ukuphazamiseka kwiinkqubo ezidibeneyo.

Umngeni wokuChaneka: Ukumakisha ngaphandle kokonakalisa

Ubunzima bendalo buxhomekeke kwinto yokuba nayiphi na inkqubo esetyenziswayo ekufakeni imakisho—ukukrolwa, ukupeyinta, okanye ukwenziwa komatshini—kufuneka ingaphazamisi i-sub-micron okanye i-nanometer flatness esele iphunyeziwe ngokugqith’ emgceni kunye nenkqubo yokulinganisa.

Iindlela zesiNtu, njengokucholwa okunzulu okanye ukubhala, kunokwazisa uxinzelelo lwasekhaya okanye ukugqwetheka komphezulu, ukubeka esichengeni ukuchaneka kwegranite eyilelwe ukuzisa. Ke ngoko, inkqubo ekhethekileyo esetyenziswa yi-ZHHIMG® isebenzisa iindlela ezenziwe ngobunjineli ukunciphisa impembelelo:

• Ukukrolwa/ukukrolwa okunganzulwanga: Iimpawu ngokuqhelekileyo zisetyenziswa ngokrolo oluchanekileyo, olungekho nzulu—kaninzi lungaphantsi kwe-±0.1 mm ubunzulu. Ubunzulu bubalulekile kuba buvumela umgca ukuba ubonakale kwaye ubambeke ngaphandle kokunciphisa kakhulu ukuzinza kwesakhiwo se-granite okanye ukuphazamisa ukucaca okupheleleyo.
• IiFillers Specialized Fillers: Imigca ekroliweyo idla ngokuzaliswa ngokungafaniyo, i-low-viscosity epoxy okanye ipeyinti. Esi sigcwalisi senzelwe ubunjineli bokunyanga ukugungxulwa komphezulu wegranite, ukuthintela ukuzimakisha ukuba kube yindawo ephezulu enokuphazamisana nemilinganiselo elandelayo okanye umphezulu wonxibelelwano.

Ukuchaneka kokuMakisha vs. I-Platform Flatness

Kubalulekile ukuba iinjineli ziwuqonde umahluko phakathi kokuchaneka komgangatho weqonga kunye nokuchaneka kokubekwa kweempawu:

• I-Platform Flatness (Ukuchaneka kweJiyometri): Lo ngowona mlinganiselo wokugqibela wendlela ukucwangciswa ngokugqibeleleyo komhlaba, kaninzi uqinisekiswa kwinqanaba le-sub-micron, eliqinisekiswe yi-laser interferometers. Lo ngumgangatho wereferensi ongundoqo.
• Ukuchaneka kokuMakisha (Ukuchaneka kweNdawo): Oku kubhekiselele kwindlela echaneke ngayo umgca othile okanye indawo yegridi ebekwe ngokunxulumene nemiphetho yedatha yeqonga okanye indawo esembindini. Ngenxa yobubanzi bendalo bomgca ngokwawo (osoloko ujikeleze ± 0.2mm ukuze ubonakale) kunye nenkqubo yokwenziwa, ukuchaneka kwendawo yokumakisha kuqinisekiswa ngokuqinisekileyo ukunyamezela kwe-± 0.1 mm ukuya ku-± 0.2 mm.

Nangona oku kuchaneka kwendawo kunokubonakala kukhululekile xa kuthelekiswa ne-nanometer flatness ye-granite ngokwayo, iimpawu zenzelwe ukukhangela okubonakalayo kunye nokusekwa, kungekhona umlinganiselo wokugqibela ochanekileyo. Umphezulu wegraniti ngokwawo uhlala ungowona uphambili, ireferensi echanekileyo engaguqukiyo, kwaye umlinganiselo wokugqibela kufuneka usoloko uthathwa kusetyenziswa izixhobo ze-metrology ukubhekisa kwiplatifti eqinisekisiweyo yeqonga.

Ukuqukumbela, iimpawu zomphezulu wesiko kwiqonga legranite luphawu oluxabisekileyo lokuphucula ukuhamba komsebenzi kunye nokuseta, kwaye lunokuphunyezwa ngaphandle kokubeka esichengeni ukusebenza kweqonga ngokuchanekileyo. Nangona kunjalo, kufuneka zicaciswe kwaye zisetyenziswe ngumenzi oyingcali, eqinisekisa ukuba inkqubo yokumakisha ihlonipha ingqibelelo esisiseko yesiseko segranite esine-ultra-high-density.
