Ungazikhetha njani iirula zokuhlola igranite ezinobunzima obufanelekileyo ngokwesipinari sobude?

Ngokungafaniyo nokushukuma kobushushu okutsala ingqalelo enkulu, ukujika kobunzima bomzimba kwenzeka kuphela ngenxa yomthwalo woomatshini. Nje ukuba irula yokuhlola igranite ibekwe phezu komsantsa ukuze ihlolwe, ubunzima bayo budala ukugoba okuncinci. Kwizicelo zexesha elifutshane, esi siphumo asibi kangako. Kodwa njengoko ububanzi obungaxhaswayo bukhula, ukujika kuyanda kakhulu. Kwanegranite emnyama yezinga eliphezulu ayinakubaleka kulo mthetho wendalo. Abasebenzisi abaninzi bokugqibela bathi umgangatho wezinto ezibonakalayo ngunobangela wokufundwa okubi, ngelixa unobangela wokwenyani kukungalingani kobunzima bomzimba nobude bomsebenzi.

Uxinano lwezinto zokwakha lubeka isiseko. I-ZHHIMG isebenzisa i-granite emnyama enoxinano oluphezulu malunga ne-3100 kg/m³, inika ubulukhuni obuphezulu ngeyunithi nganye xa kuthelekiswa nezinye izinto ezithatha indawo zemabula ezinoxinano oluphantsi. Iimveliso zemabula ezikumgangatho ophantsi zihlala zinciphisa ubukhulu kunye nobunzima ngokubanzi ukuze zinciphise iindleko; phantsi kobubanzi obuphakathi, ukugoba okucacileyo kwenzeka kwaye konakalisa ukusebenza kwe-metrology. Emva kokuzibophelela kwayo okujoliswe kubathengi, i-ZHHIMG iyala ngokungqongqo ukutshintshwa kwezinto eziphantsi kwaye ivavanya ubude bokusebenza obuvumelekileyo bomlawuli ngamnye ngexesha loyilo oluqhelekileyo.

Ububanzi obusebenzayo bubhekisa kumgama womsantsa wokwenyani phakathi kwamanqaku amabini axhasayo ngexesha lokuhlolwa kwehlabathi lokwenyani, kungekuphela nje ubude bomzimba bomlawuli. Irula ende yegranite ingasebenza ngesithuba esifutshane esisebenzayo, ngelixa iyunithi yobude obuphakathi inokujongana nomsantsa omkhulu ongaxhaswayo. Abasebenzisi kufuneka bacacise ubude bomsebenzi wokwenyani ngaphambi kokuqinisekisa ubukhulu, icandelo elinqamlezileyo kunye nobunzima bomntu obuvelayo.

Kwiimeko zesithuba esifutshane esingaphantsi kwe-800 mm, ubunzima bokuzilawula obuphakathi buhlangabezana neemfuno; ukuphambuka komxhuzulane kuhlala kuncinci, kwaye ukubaluleka kunokuya kwiindlela eziphathwayo. Xa ubude obusebenzayo bufikelela kwi-800 1600 mm, ubunzima obunqamlezileyo kunye nobunzima bokuzilawula kufuneka bunyuswe ngokufanayo ukuphucula ukumelana nokugoba. Kwiisithuba ezingaphezulu kwe-1600 mm, ubude obulula alwanelanga. Icandelo lolwakhiwo kufuneka lihlengahlengiswe, kwaye ubunzima bokuzilawula buphakanyiswe ukuze kuthintelwe ukuphambuka ngaphakathi koluhlu lokunyamezela oluchazwe yimigangatho ye-DIN, ASME kunye ne-GB metrology. Kwezinye iimeko, iindawo zokuxhasa ezilungiselelweyo nazo ziyacetyiswa ukuze kuthintelwe ukuphambuka okubangelwe ngumxhuzulane.

Kufuneka kuphetshwe ukucacisa ngokugqithisileyo. Ukuzithwala ngokugqithisileyo akuphuculi ukuchaneka ngakumbi, kodwa kuzisa iingozi zokhuseleko ngexesha lokuhamba ngesandla, ukufakelwa kunye nokuthuthwa kwindawo. Iirula ezinkulu zifuna izixhobo zokuphakamisa ezongezelelweyo kwaye zonyusa iindleko zokusebenza kwindawo yokusebenzela. Ukuzithwala ngokugqithisileyo okujolise kubude obusetyenzisiweyo kuqinisekisa ulungelelwaniso olungcono phakathi kokuqina nokusebenza.

Iqela lobunjineli le-ZHHIMG lenza ukulinganisa ukuphambuka kwirula nganye yokuhlola igranite ngokwemiqathango yenkxaso ebhengeziweyo yabathengi. Ngokusebenzisa amava e-metrology aqokelelweyo amashumi eminyaka kunye nolwazi oluqhelekileyo lwehlabathi olugubungela i-DIN 875, i-ASME kunye nezinye iinkcukacha, iingcali zilungisa i-geometry yecandelo elinqamlezileyo kwaye zibala ubunzima bokuzilinganisa obufanelekileyo, endaweni yokulandela kuphela ukhetho lweekhathalogu ezinobukhulu obumiselweyo.

Emva komatshini wokugaya izixhobo ezinkulu ngaphakathi kwindawo yokusebenzela elawulwa bubushushu, irula nganye egqityiweyo ivavanywa ngokupheleleyo. Izixhobo zovavanyo eziquka ii-interferometers ze-laser ze-Renishaw kunye namanqanaba e-elektroniki e-WYLER zirekhoda idatha ethe tye phantsi kweenkqubo zokuxhasa eziqinisiweyo. Amaxwebhu okulinganisa alandelelwa kwi-national metrology Institutes arekhoda ukusebenza phantsi kweemeko zobubanzi bethagethi, kungekuphela nje ukuba yi-static bench flatness. Olu qheliselo lunceda abathengi baqonde ukuba zeziphi iiparameter zobubanzi isixhobo esigcina umgangatho waso wokuchaneka oqinisekisiweyo.                             

Nokuba ubunzima kunye nobubanzi obuhambelanayo ngokufanelekileyo, iinkcukacha zokusetyenziswa kwentsimi zichaphazela iziphumo zokugqibela. Abaqhubi kufuneka babeke izixhaso kwiindawo ezimiselweyo ze-fulcrum ezicetyiswe ngumenzi, endaweni yokubeka indawo engacwangciswanga. Xa uhlola iziqwenga zomsebenzi eziguquguqukayo, kuphephe ukwandisa ububanzi obungaxhaswanga ngaphaya komda oqinisekisiweyo we-granite ruler. Kwizikhewu ezinkulu kakhulu, sebenzisa iindlela zokusebenza zokulinganisa amacandelo amaninzi okanye ukhethe ii-rule ezenziwe ngokwezifiso zamacandelo amakhulu. Izixhaso zokugcina kunye nezokuthutha kufuneka ziphindaphinde uyilo lwe-fulcrum olusebenza kwimeko yokusebenza ukuthintela ukwakheka koxinzelelo lwangaphakathi oluhlala luhleli.

Ukulinganisa ubunzima bomzimba wakho ngokwesikwere kubonelela ngokusebenza okuzinzileyo kwesalathiso kwiindawo ezininzi ezifuna umgudu: ukujonga indlela yesikhokelo sesixhobo somatshini, ukulungelelaniswa kwesakhelo sezixhobo ze-semiconductor, ukulinganiswa kweqonga le-motor elihambayo, ukuhlolwa kwezixhobo ezinkulu kunye nokuhlanganiswa kwesixhobo se-laser ngokuchanekileyo. Amaqabane amaninzi ehlabathi ukusuka kubavelisi beFortune 500 ukuya kumaziko ophando axhomekeke kwizixhobo zokulinganisa i-granite ezenziwe ngokwezifiso ze-ZHHIMG kwimisebenzi ye-long gap metrology.

Iqhutywa yifilosofi yayo yomgangatho yokuba ukwenziwa ngokuchanekileyo kakhulu akuvumeli ukuba kubekho ukuyekelela, i-ZHHIMG iyaqhubeka nokukhuthaza uyilo olucwangcisiweyo olujolise kwisicelo seemveliso ze-granite metrology. Ngaphaya kwezinto zekhathalogu eziqhelekileyo, iqela libonelela ngokulungiswa kwesakhiwo okusekwe kububanzi kubathengi abajongene neemeko ezikhethekileyo zokuhlolwa kwesithuba esikhulu, okususa iingozi zokuphambuka komxhuzulane kwinqanaba loyilo lwemveliso.
