Nakuba ipulatifomu ye-granite ingase ibonakale njengetshe elilula, izindlela zokukhetha zishintsha kakhulu lapho zisuka ekusetshenzisweni okuvamile kwezimboni ziye ekuhlolweni kokukhanya okubonakalayo okunezingqinamba ezinkulu kanye ne-metrology. Ku-ZHHIMG®, ukunikeza izingxenye zokunemba kubaholi bomhlaba kwezobuchwepheshe be-semiconductor kanye ne-laser kusho ukuqaphela ukuthi ipulatifomu yokulinganisa ukukhanya akuyona nje isisekelo - iyingxenye ebalulekile, engaxoxiswana ngayo yesistimu yokukhanya uqobo.
Izidingo zokuhlolwa kokukhanya—okuhlanganisa ukuthathwa kwezithombe zokukhulisa okuphezulu, ukuskena nge-laser, kanye ne-interferometry—zichazwa yisidingo sokususa yonke imithombo yomsindo wokulinganisa. Lokhu kuholela ekugxileni ezicini ezintathu ezikhethekile ezihlukanisa ipulatifomu yangempela yokukhanya kwemboni ejwayelekile.
1. Ubuningi Obuphakeme Bokunciphisa Ukudlidliza Okungalingani
Ezisekelweni ze-CNC zezimboni ezijwayelekile, insimbi ephothiwe noma i-granite evamile ingase inikeze ukuqina okwanele. Kodwa-ke, ukusethwa kwe-optical kuzwela kakhulu ekushintsheni okuncane okubangelwa ukudlidliza kwangaphandle okuvela emishinini yasefektri, izinhlelo zokuphatha umoya, noma ngisho nethrafikhi ekude.
Yilapho isayensi yezinto ezibonakalayo iba khona kakhulu. Ipulatifomu yokukhanya idinga i-granite enomswakama oyingqayizivele wezinto ezibonakalayo. I-ZHHIMG® isebenzisa i-ZHHIMG® Black Granite yayo (≈ 3100 kg/m³). Le nto enobuningi obukhulu kakhulu, ngokungafani ne-granite yezinga eliphansi noma esikhundleni semabula, inesakhiwo sekristalu esisebenza kahle kakhulu ekuqedeni amandla emishini. Umgomo akukhona nje ukunciphisa ukudlidliza, kodwa ukuqinisekisa ukuthi isisekelo sihlala siphansi lomshini elithule ngokuphelele, kunciphisa ukunyakaza okuhlobene phakathi kwelensi eqondiwe kanye nesampula ehlolwe ezingeni le-sub-micron.
2. Ukuzinza Okukhulu Kokushisa Ukuze Ulwe Nokukhukhuleka
Amapulatifomu ajwayelekile ezimboni abekezelela izinguquko ezincane zobukhulu; ingxenye yeshumi ye-degree Celsius ingase ingabi nandaba nokubhoboza. Kodwa ezinhlelweni zokukhanya ezenza izilinganiso ezinembile ngezikhathi ezinde, noma yikuphi ukukhukhuleka kokushisa ku-geometry yesisekelo kuveza iphutha elihlelekile.
Ukuze kuhlolwe ukukhanya, ipulatifomu kumele isebenze njengesinki sokushisa esine-coefficient ephansi kakhulu yokwanda kokushisa (CTE). Ubukhulu obuphezulu kanye nobuningi be-ZHHIMG® Black Granite buhlinzeka nge-inertia yokushisa edingekayo ukuze imelane nokwanda okuncane kanye nokufinyela okungenzeka ngaphakathi kwegumbi elilawulwa yisimo sezulu. Lokhu kuzinza kuqinisekisa ukuthi ibanga lokugxila elilinganisiwe kanye nokuqondana okuhleliwe kwezingxenye zokukhanya kuhlala kuzinzile, okuqinisekisa ubuqotho bezilinganiso ezithatha amahora—into engaxoxiswana ngayo yokuhlola i-wafer enesinqumo esiphezulu noma i-metrology yokubonisa iphaneli eyisicaba.
3. Ukufinyelela Ukuthamba Kwezinga Elincane Nokunemba Kwejiyometri
Umehluko obonakala kakhulu yisidingo sokuba yisicaba. Ngenkathi isisekelo sezimboni esivamile singase sihlangabezane nokuba yisicaba kweBanga 1 noma kweBanga 0 (kukalwa ngama-micron ambalwa), izinhlelo ze-optical zidinga ukunemba ebangeni le-nanometer. Leli zinga lokuphelela kwejometri liyadingeka ukuze kuhlinzekwe indiza yokubhekisela ethembekile yezigaba eziqondile kanye nezinhlelo ze-autofocus ezisebenza ngezimiso zokuphazamiseka kokukhanya.
Ukufeza nokuqinisekisa ukuthamba kwezinga le-nanometer kudinga indlela yokukhiqiza ehluke ngokuphelele. Kuhilela amasu akhethekile kakhulu asebenzisa imishini ethuthukisiwe njenge-Taiwan Nanter grinders futhi kuqinisekiswa imishini ye-metrology eyinkimbinkimbi njenge-Renishaw Laser Interferometers. Le nqubo kumele yenzeke endaweni ezinzile kakhulu, njengezindawo zokusebenzela ze-ZHHIMG® ezividliza, ezilawulwa yisimo sezulu, lapho ngisho nokunyakaza komoya okucashile kuncishiswa khona.
Empeleni, ukukhetha ipulatifomu yokunemba kwe-granite yokuhlola okubonakalayo kuyisinqumo sokutshala imali engxenyeni eqinisekisa ngenkuthalo ukunemba kokulinganisa okubonakalayo uqobo. Kudinga ukubambisana nomkhiqizi obheka isitifiketi se-ISO 9001 kanye nokulandelela okubanzi hhayi njengezici zokuzikhethela, kodwa njengezidingo eziyisisekelo zokungena ezweni le-ultra-precision optics.
