Ingabe Amapulatifomu Okucacisa I-Granite Angaba Nezimpawu Zomphezulu?

Lapho kufakwa ipulatifomu yokunemba kwe-granite ye-metrology noma i-assembly esezingeni eliphezulu, amakhasimende avame ukubuza: singakwazi yini ukwenza ngokwezifiso ubuso ngezimpawu—njengemigqa yokuxhumanisa, amaphethini egridi, noma amaphuzu athile okubhekisela? Impendulo, evela kumkhiqizi onembile kakhulu njenge-ZHHIMG®, inguyebo oqinisekile, kodwa ukusetshenziswa kwalezi zimpawu kuyikhono elicashile elidinga ubuchwepheshe ukuqinisekisa ukuthi izimpawu zithuthukisa, kunokuba zinciphise, ukunemba okuyinhloko kwepulatifomu.

Inhloso Yokumaka Okuphezulu Okunembile

Kumapuleti amaningi ajwayelekile omhlaba we-granite noma izisekelo zomshini, umgomo oyinhloko ukufeza ukuthamba okuphezulu kakhulu kanye nokuqina kwejometri. Kodwa-ke, kuzinhlelo zokusebenza ezifana nama-jig okuhlanganisa amakhulu, iziteshi zokulinganisa, noma ukusethwa kokuhlola ngesandla, izinsiza ezibonakalayo nezingokwenyama ziyadingeka. Ukumaka kobuso kufeza imisebenzi eminingana ebalulekile:

1. Iziqondiso Zokuqondanisa: Ukunikeza imigqa yokubhekisela esheshayo nebonakalayo yokubeka kahle izinto noma izingxenye ngaphambi kokufaka izigaba zokulungisa okuncane.
2. Izinhlelo Zokuhlanganisa: Ukusungula igridi yokuhlanganisa ecacile, yokuqala (isb., ama-axes e-XY) angalandeleka endaweni ephakathi noma kudatha yomkhawulo.
3. Izindawo Ezingadingi Ukusetshenzwa: Ukumaka izindawo lapho imishini kungafanele ibekwe khona ukuze kulondolozwe ibhalansi noma kuvinjelwe ukuphazamiseka kwezinhlelo ezihlanganisiwe.

Inselele Yokunemba: Ukumaka Ngaphandle Kokulimaza

Ubunzima obukhona buseqinisweni lokuthi noma iyiphi inqubo esetshenziswa ukufaka izimpawu—ukuqopha, ukupenda, noma ukukhanda—akumelwe iphazamise ukuthamba kwe-sub-micron noma i-nanometer osekufezwe yinqubo eqinile yokugoqa nokulinganisa.

Izindlela zendabuko, njengokuqopha okujulile noma ukubhala, zingaletha ukucindezeleka kwendawo noma ukuphambuka kobuso, okwehlisa ukunemba okuklanyelwe ukuletha i-granite. Ngakho-ke, inqubo ekhethekile esetshenziswa yi-ZHHIMG® isebenzisa izindlela eziklanywe ukunciphisa umthelela:

• Ukuqopha/Ukuqopha Okungajulile: Izimpawu zivame ukusetshenziswa ngokuqopha okuqondile, okungajulile—ngokuvamile okungaphansi kuka-±0.1 mm ukujula. Lokhu kujula kubalulekile ngoba kuvumela umugqa ukuthi ubonakale futhi uthinteke ngaphandle kokunciphisa kakhulu ukuqina kwesakhiwo se-granite noma ukuphambukisa ukuthamba okuphelele.
• Ama-Filler Akhethekile: Imigqa eqoshiwe ivame ukugcwaliswa nge-epoxy noma upende ohlukile, one-viscosity ephansi. Lokhu kugcwalisa kwenzelwe ukupholisa ubuso be-granite, ukuvimbela ukumakwa ngokwako ekubeni yindawo ephezulu engaphazamisa ukulinganisa okulandelayo noma izindawo zokuthintana.

Ukunemba Kwezimpawu vs. I-Platform Flatness

Kubalulekile ukuthi onjiniyela baqonde umehluko phakathi kokunemba kokusicaba kwepulatifomu kanye nokunemba kokubekwa kwezimpawu:

• Ukuthamba Kweplatifomu (Ukunemba Kwejiyomethri): Lesi yisilinganiso sokugcina sokuthi ubuso buhlelwe kahle kangakanani, ngokuvamile siqinisekiswa ezingeni le-sub-micron, siqinisekiswa yi-laser interferometers. Lena yindinganiso yokubhekisela eyinhloko.
• Ukunemba Kokumaka (Ukunemba Kwesikhundla): Lokhu kubhekisela ekutheni umugqa othile noma iphuzu legridi libekwa ngokunembile kangakanani maqondana nemiphetho yedatha yesikhulumi noma iphuzu eliphakathi. Ngenxa yobubanzi obungokwemvelo bomugqa ngokwawo (ovame ukuba cishe ngu-±0.2mm ukuze kubonakale) kanye nenqubo yokukhiqiza, ukunemba kwesimo sokumakwa kuvame ukuqinisekiswa ekubekezeleleni okungu-± 0.1 mm kuya ku-± 0.2 mm.

Nakuba lokhu kunemba kwendawo kungase kubonakale kukhululekile uma kuqhathaniswa nokusicaba kwe-nanometer kwe-granite uqobo, izimpawu zenzelwe ukubhekisela nokusethwa okubonakalayo, hhayi ukulinganisa kokugcina kokunemba. Ubuso be-granite ngokwalo buhlala buyinkomba yokunemba eyinhloko, engaguquki, futhi ukulinganisa kokugcina kufanele kuthathwe njalo kusetshenziswa amathuluzi okukala abhekisela endaweni eyisicaba eqinisekisiwe yepulatifomu.

Ekuphetheni, izimpawu zobuso ezenziwe ngokwezifiso epulatifomu yegranite ziyisici esibalulekile sokuthuthukisa ukuhamba komsebenzi kanye nokusetha, futhi zingenziwa ngaphandle kokuphazamisa ukusebenza kahle kwepulatifomu. Kodwa-ke, kumele zichazwe futhi zisetshenziswe ngumkhiqizi ochwepheshe, oqinisekisa ukuthi inqubo yokumaka ihlonipha ubuqotho obuyisisekelo besisekelo segranite esinobukhulu obuphezulu kakhulu.
