Iipleyiti zomphezulu wegranite zizixhobo ezichanekileyo ezisetyenziswa kakhulu kwi-metrology, ekuhlolweni, nakwizicelo zoomatshini. Zenziwe ngegranite yendalo esemgangathweni ophezulu, exatyiswa ngokuzinza kwayo, ukuqina kwayo, kunye nokuba tyaba. Kodwa zichaneke kangakanani ezi pleyiti?
Uzinzo lweNdalo
I-granite yenziwa kwiminyaka eyizigidi phantsi koxinzelelo olukhulu nobushushu, nto leyo ebangela isakhiwo esixineneyo nesincinci. Olu qina lwendalo lwenza i-granite ibe yinto efanelekileyo kwiiplati zomphezulu, njengoko imelana nokuguquguquka kobushushu, ukufuma, kunye noxinzelelo loomatshini. Enyanisweni, i-granite inomlinganiselo ophantsi wokwanda kobushushu, oko kuthetha ukuba iyakhula kwaye iyancipha kancinci xa kutshintshwe ubushushu. Le propati iqinisekisa ukuba umphezulu weplati uhlala uthe tyaba kwaye unyanisekile, nokuba kukwiindawo ezinzima.
Ukwenziwa kweMveliso echanekileyo
Ukuze kufezekiswe amanqanaba aphezulu okuchaneka, iipleyiti zomphezulu wegranite zidlula kwinkqubo yokwenziwa enzima. Okokuqala, ibhloko yegranite ikhethwa ngononophelo ngenxa yomgangatho wayo kunye nokuhambelana kwayo. Emva koko, iyasikwa ngokobukhulu obufunekayo kunye nokuma kwayo. Okulandelayo kuza inkqubo yokuleqa nokupolisha, apho umphezulu ucocwa kancinci kusetyenziswa izinto ezirhabaxa. Le nkqubo inobunono obuncinci inokufikelela kubunzima obuphantsi kakhulu bomphezulu kunye nokunyamezela okuphezulu kokuthe tyaba.
Imigangatho yokuchaneka
Ukuchaneka kweepleyiti zomphezulu wegranite kudla ngokuchazwa kukunyamezela kwazo ukuba zithe tyaba. Ngokutsho komgangatho we-American Society of Mechanical Engineers (ASME) B89.3.7, iipleyiti zomphezulu zilinganiswa ngokusekwe ekubeni zithe tyaba. Owona mgangatho uphezulu, i-AA, unezona mpawu ziqinileyo, nto leyo eyenza ukuba zifaneleke kwiilabhoratri zokulinganisa kunye ne-metrology echanekileyo. Iipleyiti zeBanga A zihlala zisetyenziswa kwiindawo zokuhlola, ngelixa iipleyiti zeBanga B, ezineempendulo ezikhululekileyo kancinci, zinokufumaneka kumgangatho weevenkile.
Umzekelo, ipleyiti yomphezulu wegranite ye-AA eyi-12" x 12" inokuba nobunzima obuthe tyaba obuyi-±0.00005 intshi kuyo yonke indawo yayo. Eli nqanaba lokuchaneka livumela ukulinganiswa okuchanekileyo kunye nokulinganiswa kwezinye izixhobo kunye nezinto.
Izinto Ezichaphazela Ukuchaneka
Nangona iipleyiti zomphezulu wegranite zichanekile ngokwemvelo, zininzi izinto ezinokuchaphazela ukusebenza kwazo ngokuhamba kwexesha. Ukuphathwa ngendlela engafanelekanga, njengokuwisa okanye ukufaka ipleyiti kumandla agqithisileyo, kunokubangela iitships okanye imingxunya enokuchaphazela ukuthamba. Ukongeza, izinto ezingqongileyo ezifana notshintsho olukhulu lobushushu okanye amanqanaba aphezulu okufuma nazo zinokuchaphazela ukuchaneka kwepleyiti. Ukucoca nokugcinwa rhoqo, kunye nokugcinwa ngokufanelekileyo, kubalulekile ukugcina ukuchaneka kwepleyiti.
Ukuqukumbela, iipleyiti zomphezulu wegranite zibonelela ngokuchaneka okugqwesileyo, nto leyo ezenza zibe lukhetho oluthembekileyo kwiindlela zokusebenza apho ukuchaneka kubaluleke kakhulu. Uzinzo lwazo lwendalo, kunye neendlela zokwenza ngokuchanekileyo, zivumela ukuba zibonelele ngomphezulu ozinzileyo nochanekileyo wesalathiso kwiindidi ezahlukeneyo zamashishini, ukusuka kwinqwelo-moya kunye neemoto ukuya kwimveliso ye-elektroniki kunye nezixhobo zonyango.
