Botsitso le ho nepahala ha mochini ofe kapa ofe o nepahetseng haholo—ho tloha ho Mechini e Mekaneng ea Coordinate Measuring (CMMs) e meholo ho ea ho lisebelisoa tse tsoetseng pele tsa lithography tsa semiconductor—haholo-holo li itšetlehile ka motheo oa eona oa granite. Ha ho sebetsanoa le metheo ea monolithic ea boholo bo boholo, kapa Liphanele tse Pharaletseng tsa Granite tse rarahaneng tsa likarolo tse ngata, ts'ebetso ea ho kopanya le ho kenya e bohlokoa joalo ka ho nepahala ha tlhahiso ka boeona. Ho beha phanele e felileng feela ha hoa lekana; litlhoko tse ikhethileng tsa tikoloho le tsa sebopeho li tlameha ho finyelloa ho boloka le ho sebelisa ho batalla ha sub-micron ea phanele.
1. Motheo: Sebaka se Tsitsitseng, se Lekaneng
Maikutlo a fosahetseng a atileng haholo ke hore phanele ea granite e nepahetseng, joalo ka e entsoeng ka granite ea rona e nang le botenya bo phahameng ea ZHHIMG® Black Granite (3100 kg/m³), e ka lokisa mokatong o sa tsitsang. Leha granite e fana ka ho tiea ho ikhethang, e tlameha ho tšehetsoa ke sebopeho se entsoeng bakeng sa ho kheloha ho fokolang nako e telele.
Sebaka sa kopano se tlameha ho ba le substrate ea konkreite e seng feela e bataletseng empa hape e phetse hantle, hangata ho latela litlhaloso tsa boemo ba sesole bakeng sa botenya le ho teteana—e bonts'ang fatše ea konkreite e teteaneng haholo ea $1000mm$ liholong tsa kopano tsa ZHHIMG. Habohlokoa le ho feta, substrate ena e tlameha ho aroloa mehloling ea kantle ea ho thothomela. Moralong oa metheo ea rona e meholohali ea mechini, re kenyelletsa likhopolo tse kang moalo o thibelang ho thothomela o potolohileng likamore tsa rona tsa metrology ho netefatsa hore motheo ka booona o tsitsitse ebile o arohane.
2. Lera la ho Ikarola: Ho Kopanya le ho Lekanya
Ho kopana ka ho toba pakeng tsa phanele ea granite le motheo oa konkreite ho qojoa ka tieo. Motheo oa granite o tlameha ho tšehetsoa libakeng tse itseng, tse baloang ka lipalo ho tlosa khatello ea ka hare le ho boloka jiometri ea eona e netefalitsoeng. Sena se hloka sistimi ea ho leka-lekanya ea profeshenale le lera la grouting.
Hang ha phanele e behiloe hantle ka ho sebelisa li-jack kapa li-wedge tse ka fetoloang, grout e matla haholo, e sa fokotseng, e nepahetseng e pompeloa ka har'a sekoti se pakeng tsa granite le substrate.

Mohato ona o fetola phanele ea granite le motheo ka katleho hore e be boima bo le bong, bo kopaneng, le bo tiileng.
3. Tekano ea Mocheso le ea Nakoana
Joalo ka mesebetsi eohle ea metrology e nepahetseng haholo, mamello ke ea bohlokoa haholo. Phanele ea granite, thepa ea grouting, le substrate ea konkreite kaofela li lokela ho fihlela tekano ea mocheso le tikoloho e potolohileng ea ts'ebetso pele ho etsoa liteko tsa ho qetela tsa ho hokahanya. Ts'ebetso ena e ka nka matsatsi bakeng sa liphanele tse kholo haholo.
