I-precision granite ibisoloko ibonwa njengenye yezona zinto zithembekileyo kwi-metrology kunye nezakhiwo zoomatshini ezichanekileyo. Xa ithelekiswa nentsimbi ephosiweyo okanye intsimbi, i-granite ekumgangatho ophezulu inika uzinzo olubalaseleyo kunye nokuchaneka kwexesha elide, okwenza ukuba ilungele iindawo zokubhekisa, iziseko zoomatshini, inkxaso yesikhokelo esithe ngqo, kunye nezinto ezibalulekileyo ezisetyenziswa kumatshini wokulinganisa odibeneyo, ii-interferometer ze-laser, izixhobo zomatshini we-CNC, kunye neenkqubo zokuhlola ze-semiconductor.
Umbuzo omnye odla ngokubuzwa ngabasebenzisi kukuba kutheni izinto zegranite ezichanekileyo zigqunywe ngomaleko omncinci weoyile ngaphambi kokuba zithunyelwe, kwaye kutheni kucetyiswa ukuba kufakwe ioyile xa izixhobo zingasasetyenziswa ixesha elide. Ekubeni igranite ingagqwali, ngokucacileyo ioyile ayiyonto yokuthintela ukugqwala. Endaweni yoko, ifilimu ekhuselayo isebenza injongo eyahlukileyo nesebenzayo: ukukhusela ukuchaneka komphezulu wokusebenza.
Izinto zegranite zenziwe ngokunyamezelana okuqinileyo kakhulu, kwaye umphezulu wazo kufuneka uhlale ungenaluthuli, amasuntswana arhabaxa, kunye nezinye izinto ezingcolisayo. Nokuba yinkunkuma encinci encinci inokuchaphazela ukuchaneka kokulinganisa, kwaye ukusula okomileyo amasuntswana anjalo ngqo kumphezulu kunokubangela imikrwelo emincinci. Nangona igranite imelana kakhulu nokuguquguquka kwaye ayenzi ii-burrs ezifana nesinyithi, imikrwelo enzulu kumphezulu ochanekileyo inokuchaphazela ukusebenza kwaye inokufuna ukuphinda idityaniswe okanye ilungiswe.
Ngokufaka ifilimu yeoyile ekhaphukhaphu—edla ngokuba yioyile yetransformer okanye umxube weoyile yomatshini kunye nedizili ongu-1:1—umphezulu uba lula kakhulu ukuwucoca. Uthuli kunye namasuntswana amancinci anamathela kwioyile endaweni yelitye ngokwalo, kwaye anokususwa ngokusula ifilimu. Oku kunciphisa umngcipheko wokutsala amasuntswana arhabaxa kumphezulu wokusebenza kwaye kugcina ukuthembeka kwexesha elide kweplani yesalathiso. Kwizixhobo ezigcinwe ixesha elide, ifilimu yeoyile ibaluleke kakhulu kuba ukuqokelelana kothuli kuyanda ngokuhamba kwexesha. Ngaphandle kweoyile, ukucoca okomileyo kunokushiya amanqaku abonakalayo okanye imikrwelo echaphazela ukuchaneka kokulinganisa.
Ngexesha lokwenziwa, izinto zegranite ezichanekileyo zihlala zifuna umatshini owongezelelweyo ukuze zihlanganiswe nezinye iinkqubo zoomatshini. Ngokuxhomekeke kwimizobo yabathengi, isakhiwo segranite sinokubandakanya i-threaded inserts, ii-T-slots, ii-counterbores, okanye ii-through-holes. I-insert nganye ibotshelelwe endaweni emva kokwenziwa ngononophelo kwegranite ukuya kubukhulu obuchaziweyo, kwaye ukunyamezelana kwesimo kufuneka kulawulwe ngokuqinileyo ukuqinisekisa ukuhlanganiswa ngokufanelekileyo kunye neendawo zokudibana. Inkqubo yokwenziwa engqongqo—ukugubungela ukubhola, ukubopha ii-bushings zesinyithi, kunye nokugqitywa kokugqibela komphezulu—kuqinisekisa ukuba zonke iimfuno zejometri ziyafezekiswa kwaye icandelo ligcina ukuchaneka kwalo emva kokufakwa.
Igranite esemgangathweni ophezulu ineenzuzo ezininzi ezibalulekileyo kwizicelo zobunjineli obuchanekileyo. Izinzile ngokwendalo, kunye noxinzelelo lwangaphakathi olukhutshwa kukwaluphala kwexesha elide kwejoloji. Ayinakumelana nokugqwala, ukufuma, kunye neekhemikhali ezininzi. I-coefficient yayo yokwandiswa kobushushu obuphantsi inciphisa utshintsho lokuchaneka ngenxa yokuguquguquka kobushushu. Ngokungafaniyo nemiphezulu yesinyithi, iimpembelelo ezincinci kwigranite zibangela imingxunya emincinci endaweni yee-burrs eziphakanyisiweyo, ngoko ke iplani yesalathiso ayijiki.
Ngenxa yezi zizathu, i-granite iyaqhubeka nokudlala indima ebalulekileyo kwi-metrology yanamhlanje, izixhobo ze-semiconductor, kunye nokuveliswa okuchanekileyo kakhulu. Ukuphathwa ngokufanelekileyo—njengokufaka ifilimu yeoyile ngaphambi kokuthunyelwa okanye ukugcinwa ixesha elide—kunceda ukuqinisekisa ukuba inxalenye nganye ye-granite echanekileyo igcina ukusebenza kwayo ukusuka kumzi-mveliso ukuya kumsebenzisi wokugqibela, ixhasa umlinganiselo othembekileyo kunye nemveliso echanekileyo kakhulu kuluhlu olubanzi lwamashishini.
