Impahla Yamatshe Elwa Nokuguga: Indlela I-Granite Ephakeme Egcina Ngayo Ukunemba Kwangempela Iminyaka Engamashumi

Emkhakheni wokukhiqiza onembile kakhulu, lapho ngisho nokuguquguquka okuncane kokunemba kungabangela ukwehluleka kokukhiqiza okubizayo, ukusebenza okulwa nokuguga kwezinto eziyisisekelo kuyisici sokwakheka noma ukuqeda. Ngokungafani nezinsimbi ezivame ukukhukhuleka, izinto ezihlanganisiwe ezisengozini yokukhathala kwe-resin, kanye nemabula esezingeni eliphansi egoba phakathi neminyaka, i-granite emnyama ephezulu ye-ZHHIMG ivelele ngekhono layo eliyingqayizivele lokugcina ukunemba okulinganiswe efektri amashumi eminyaka. Njengomdlali wemboni kuphela ophethe izitifiketi ze-ISO9001, ISO45001, ISO14001, kanye ne-CE, i-ZHHIMG isebenzisa izakhiwo ze-geological ze-granite kanye nezinqubo zokukhiqiza eziqinile ukuze ichaze kabusha ukuzinza kokunemba kwesikhathi eside kwezimboni zomhlaba wonke ezinembile kakhulu.

I-granite emnyama ye-ZHHIMG esezingeni eliphezulu, eyakhiwe ngamakhulu ezigidi zeminyaka yokwakheka kwe-geological, inesisindo esingaba ngu-3100kg/m³—idlula ozakwabo baseYurophu nabaseMelika kanye nemabula enezimbobo ezisebenza kahle kakhulu, eyakhiwe ngendlela engavamile esetshenziswa kabi ngabakhiqizi abancane. Izinhlamvu zayo zamaminerali ezincane, ezixhumene kanye nokuntuleka kwezihlanganisi eziphilayo kuqeda ukukhukhuleka, ukuhlukaniswa kwezingqimba, kanye nokuguquguquka kokukhathala okuhlupha izinto ezihlukile. Inamathela ngokuqinile esibophweni sayo esithi “Akukho ukukopela, Akukho ukufihla, Akukho ukudukisa”, i-ZHHIMG ithola yonke i-ore eluhlaza kusuka kuma-deposits ekhwalithi ephezulu, iyigcina endaweni yamatshe enikezelwe engu-20,000m² futhi ihlola ngokucophelela ukuze isuse imifantu nokungcola—isusa izingozi zokuguga kusukela ekuqaleni.

I-coefficient yokwanda kokushisa okuphansi kakhulu kwale nto ithuthukisa kakhulu izici zayo zokulwa nokuguga, inciphisa izinguquko zobukhulu ezibangelwa ukushintshashintsha kwezinga lokushisa elijikelezayo kuma-semiconductor fabs, ama-workshop okucubungula nge-laser, kanye nama-lab e-metrology. Lokhu kuzinza kwemvelo kuqinisekisa ukuthi i-granite imelana nezingcindezi zemvelo ezisheshisa ukuguga kwezinye izinto, ibeka isisekelo esiqinile sokugcinwa kokunemba kwesikhathi eside.                                                   

Ukucubungula ukucindezeleka okusele, uma kungalungiswanga, kungabangela ukuguquka okuhamba kancane kwe-granite eminyakeni edlule—okuphazamisa ukunemba. Ngokungafani nezimboni ezincane ezingaqedi ukukhululeka ekucindezelekeni ukuze kusheshiswe ukulethwa, i-ZHHIMG isebenzisa umjikelezo wokuguga kwemvelo wezinyanga eziyi-6-12 ovulekile kuzo zonke izikhala ze-granite ngaphambi kokuqeda kahle. Le nqubo ende iqeda ngokuphelele ukucindezeleka okuqongelelwe ngesikhathi sokumba kanye nomshini wokumba onzima, isuse izingozi zokuguquka okufihliwe ezingavela isikhathi eside ngemva kokulethwa.

Ngokuhambisana nokuguga kwemvelo, ochwepheshe be-ZHHIMG—abaningi babo abaneminyaka engaphezu kwengu-30 yesipiliyoni—benza i-lapping ngesandla yezinga le-micron, beqeda kancane ukucindezeleka kwe-micro-surface kusuka ekugayweni kwe-CNC okusheshayo. Ukunemba kwabo okungenakuqhathaniswa kokuthinta, okuvame ukubizwa ngokuthi “amazinga kagesi okuhamba” ngamakhasimende, kuqinisekisa ukususwa kwezinto ezifanayo (0.1–1μm ngephasi ngalinye) kanye nokusatshalaliswa kokucindezeleka okulinganiselayo, ngisho nasezingxenyeni ze-monolithic ezingamamitha angu-20 ubude, ezingamathani ayi-100, ezivalela endaweni ezinzile unomphela.

Izindawo zokukhiqiza ezingazinzile zingaletha ukuguga kokwenziwa, zigugule ukuzinza okungokwemvelo kwe-granite. Indawo yokusebenzela ye-ZHHIMG engu-10,000m² engaguquki yokushisa nomswakama yenzelwe ukuqeda izingozi ezinjalo: iphansi layo likakhonkolo eliqinile kakhulu elingu-1000mm ubukhulu kanye nemisele yokulwa nokudlidliza engu-500mm ububanzi, engu-2000mm ububanzi ivimba ukushaqeka kwangaphandle okuvela kuma-crane asefektri kanye nethrafikhi yomgwaqo. Ama-crane athule angaphezulu avimbela imithwalo yokushaqeka ngesikhathi sokuphathwa, kuyilapho izinga lokushisa elizinzile elingu-20℃ ± 0.2℃ kanye nohlelo lokususa uthuli olunengcindezi embi lugwema ukucindezeleka kokushisa kanye nokuklwebheka kobuso.

Imishini yokugaya emine ye-Nan Te engenisiwe (ngamunye ubiza ngaphezu kwama-USD angu-500,000) ivumela ukucutshungulwa okuphansi, okuqhubekayo kwamapulatifomu anembile afinyelela ku-6000mm ubude. Indawo yokuhlanganisa ezinikele engenalo uthuli, elingisa amazinga okuhlanza e-semiconductor, iqinisekisa ukuthi ukuqeda kokugcina kanye nokuhlanganiswa akuphazamiseki, inikeza izingxenye ze-granite ezingenazo iziphambeko zokuguga ezibangelwa ukwenziwa.

Iqondiswa yifilosofi ethi “Awukwazi ukukhiqiza lokho ongakwazi ukukulinganisa,” i-ZHHIMG iqinisekisa ukusebenza kwe-granite yayo yokulwa nokuguga ngemishini yokuhlola yezinga lomhlaba, konke okulinganiswe yiJinan kanye neShandong Metrology Institutes (okulandelelwa yiNational Institute of Metrology). Amathuluzi afaka phakathi izinkomba zokudayela ze-German Mahr 0.5μm, amazinga kagesi e-Swiss WYLER, kanye nama-interferometer e-laser e-British Renishaw alinganisa ukuqina, ukwanda kokushisa, kanye neminye imingcele ebalulekile, okuqinisekisa ukuhambisana ne-DIN, ASME, JIS, kanye neminye izindinganiso zomhlaba wonke.

Ukubambisana kwesikhathi eside nezikhungo eziphezulu (iNational University of Singapore, iStockholm University, kanye nezikhungo zomhlaba wonke ze-metrology) kuqhubekisela phambili ukuthuthukiswa okuqhubekayo kwezinqubo zokunciphisa ukucindezeleka kanye nokuhlolwa kwezinto ezibonakalayo, okwandisa isikhathi sokugcina ukunemba kwe-granite.

Izingxenye ze-granite ezilwa nokuguga ze-ZHHIMG—kufaka phakathi izisekelo, ama-air bearings, amapuleti omhlaba, kanye nama-ruler okulinganisa—zisetshenziswa kabanzi emishinini ye-semiconductor, kuma-laser e-femtosecond, kuma-CT ezimboni, kanye nasemishinini yokuhlola ibhethri le-lithium. Amaklayenti e-Fortune Global 500 (i-Apple, i-Samsung, i-Bosch, i-GE) kanye nabadlali abaphambili (i-Akribis, i-Vitrox) aqinisekisa ukuthi i-granite ye-ZHHIMG igcina ukunemba kwezinga le-nano iminyaka eyi-10-15, igwema ukulinganiswa kabusha okuvamile kanye nokufakwa esikhundleni okudingekayo kwemikhiqizo yamatshe aphansi.

Isekelwa yizimpawu zokuhweba zamazwe ngamazwe ezingaphezu kuka-20 kanye namalungelo obunikazi (abhaliswe nge-CCPIT e-EU, e-US, naseNingizimu-mpumalanga ye-Asia), ubuchwepheshe be-granite bokulwa nokuguga be-ZHHIMG buvikelwe emhlabeni jikelele, buqinisa isimo salo njengomlingani othembekile wezinhlelo zokusebenza ezinembile kakhulu.

Esikhathini lapho ukukhiqizwa okunembile kakhulu kudinga ukunemba okungaguquki emashumini eminyaka edlule, i-granite emnyama ye-ZHHIMG esezingeni eliphezulu ichaza kabusha ukusebenza kokulwa nokuguga. Ukuzinza kwayo kwemvelo, okuhlangene nokuguga kwemvelo okujwayelekile, ukukhiqizwa okulawulwayo, kanye nokuqinisekiswa okulandelekayo, kuqinisekisa ukuthi ukunemba okulinganiswe efektri kuhlala isikhathi eside sokusebenza kwemishini ephezulu. Iqondiswa yinqubomgomo yayo yekhwalithi ethi “Ibhizinisi elinembile alikwazi ukuba lukhuni kakhulu” kanye nomoya othi “Isibindi sokuba phambili; Isibindi sokuqamba izinto ezintsha,” i-ZHHIMG iyaqhubeka nokubeka uphawu lwezingxenye zokunemba ezihlala isikhathi eside, ezilwa nokuguga—inika amandla imboni yomhlaba wonke enembile kakhulu ngokuthembeka okuhlala isikhathi eside.
