Ipleyiti yomphezulu wegranite ayitshixi kakhulu. Akukho ngxolo yokugquma, akukho kukhanya kwesilumkiso, akukho mqondiso ucacileyo wokuba ukutyibilika kuye kwaphela ngenxa yokunyamezelana. Ihlala apho ijongeka ithe tyaba njengoko yayinjalo ngomhla wokuhanjiswa, de kube ngumsebenzisi we-CMM aqaphele ingxaki ephindaphindwayo ebuyela umva - emva kosuku olunzima lokusombulula iingxaki - kumphezulu obhekisa kuwo. Uninzi lwaloo ngxaki lunokuphetshwa, kwaye uninzi lwayo luxhomekeke kwimikhwa engenanto yakwenza nomgangatho wegranite.
Kutheni iGranite Ihamba Nokuba Akukho Mntu Uyichukumisayo
Ukulahleka kwe-flatness kwi-aipleyiti yomphezulungesiqhelo ayikokuguguleka okukhulu okuvela kwisiganeko esinye. Iyaqokelelana: iipateni zokusetyenziswa kwindawo ethile, ukucoca okungalinganiyo, ukujikeleza kobushushu, kunye - rhoqo kunokuba iilabhoratri zilindele - inkxaso engafanelekanga. Ipleyiti ephumle kwibhentshi engalinganiyo, okanye exhaswe kwiindawo ezingalunganga xa kuthelekiswa neendawo zayo ezithwele umthwalo, iya kutshona ngemicroscope kangangeenyanga. Igranite izinzile ngokwemilinganiselo xa ithelekiswa nesinyithi, kodwa "izinzile" ayithethi "ukukhuseleka kwifiziksi." Uxinano lubalulekile apha; ilitye elinoxinano oluphezulu, kuluhlu lwe-2,900–3,100 kg/m³, lihlala ligcina umhlaba walo ngcono phantsi komthwalo oqhubekayo kunezinto ezikumgangatho ophantsi ezine-porosity yangaphakathi engaphezulu, nto leyo ebangela ukuba zonke "igranite emnyama" zingasebenzi ngokufanayo kwiminyaka emihlanu yobomi benkonzo.
Ukucoca: Okuncinci Kungaphezulu, Kodwa Yenza Ngendlela Efanelekileyo
Eyona mpazamo inkulu yokulungisa esiyibonayo ixelwa ebaleni asikokungahoywa — kukucocwa okunamandla kakhulu. Izinyibilikisi ezingalinganiswanga ngegranite, amalaphu arhabaxa, okanye ukusula okomileyo okutsala uthuli phezu komphezulu zonke zinegalelo ekukrweleni okuncinci okuqokeleleka ekuphambukeni kokwenyani okuthe tyaba ngokuhamba kwexesha. Isicoci segranite esingathathi cala esine-pH, ilaphu elingena-lint, kunye nokuchukumisa okuncinci kuhamba phambili kakhulu kunokuba abantu belindele. Inkunkuma eyomileyo kufuneka isuswe, ingatsalwa. Ukuba ipleyiti isetyenziswa kakhulu imihla ngemihla, ukusula ngokukhawuleza xa kutshintshwa ishifti kubaluleke ngaphezu kokucoca nzulu kanye ngenyanga.
Ugcino kunye noLawulo lokusingqongileyo
Ukutshintshatshintsha kobushushu yeyona nto yesibini iphambili, kwaye kulapho uninzi lweelabhoratri luchitha khona imali encinci xa kuthelekiswa nebhajethi yezixhobo esele bezichithile. Ipleyiti yomphezulu egcinwe okanye esetyenziswa kwigumbi elinokutshintshatshintsha kwemihla ngemihla kwe-5–10°C iyazichasa ngaphambi kokuba kuthathwe umlinganiselo omnye. Kwiindawo zethu zokulinganisa nokuhlanganisa, izinto zegranite ziphathwa kumagumbi alawulwa bubushushu kunye nomswakama - kungengenxa yokuba izinto azinakuphila utshintsho olujikelezayo, kodwa ngenxa yokuba ukugcina ukunyamezelana okuthe nkqo kangangeminyaka kufuna ukususa loo nguqu ngokupheleleyo endaweni yokuyihlawulela emva koko. Kwiilabhoratri ezininzi zemizi-mveliso, ulawulo olupheleleyo lwemozulu alunamsebenzi, kodwa ukugcina ipleyiti kude nee-vents ze-HVAC, ilanga ngqo, kunye nezixhobo ezivelisa ubushushu bendawo yinguqulelo engabizi kakhulu yomgaqo ofanayo.
Ukuhanjiswa kwemithwalo kunye nokuphathwa kwayo
Ipleyiti nganye yomphezulu iyile iindawo zokuxhasa, kwaye iyilayisha ngaphandle kwezo ndawo - nokuba okwethutyana, nokuba kukho into ebonakala ilula - ifaka uxinzelelo igranite eyayingadalwanga ukuba ifunxe ngokulinganayo. Oku kusebenza ngexesha lokusetyenziswa nangexesha lokuthuthwa. Ukuphakamisa ipleyiti ngendlela engafanelekanga, okanye ukuyivumela ukuba iphumle ngokungalinganiyo ngexesha lokufuduka kwesakhiwo, sisizathu esiqhelekileyo nesinokuthintelwa sokulungiswa kwakhona kwangoko.
Yintoni Eyandisa Ixesha Lokulinganisa
Amaxesha okulinganisa awaxhomekekanga; abonisa ingcamango malunga nesantya sokutyibilika phantsi kokuphathwa okuqhelekileyo. Iilebhu eziwandisa ngokwenene la maxesha zivame ukwenza izinto ezintathu rhoqo: ukulawula ukuguquguquka kwendalo, ukucoca ngokuchanekileyo nangokuthe rhoqo endaweni yokucoca ngamandla nangamaxesha athile, kunye nokugcina iinkqubo ezifanelekileyo zokuxhasa nokuphatha. Akukho nanye kwezi ethatha indawo yokulinganisa - kuthetha ukuba ipleyiti isenokuba ngaphakathi kokunyamezelana xa loo mhla wokulinganisa ufika, endaweni yokufuna uhlolo lwexeshana olungacwangciswanga.
Ukulandelelana kubalulekile nalapha. Izatifikethi zokulinganisa kufuneka zibuyele kwiziko lesizwe elivunyiweyo le-metrology, kwaye kufanelekile ukuqinisekisa ukuba nabani na olinganisa ipleyiti yakho - nokuba liqela langaphakathi elisebenzisa inqanaba le-elektroniki eliqinisekisiweyo okanye ilebhu yangaphandle - ulandela umgangatho ovunyiweyo ofana ne-DIN 876, ASME B89.3.7, okanye i-JIS B7513, endaweni yendlela engekho sesikweni yangaphakathi. Silinganisa imveliso yethu yegranite ngokuchasene nesatifikethi seJinan kunye neShandong metrology Institute, kunye nokulandelelana ukuya kuthi ga kwimigangatho yesizwe, ikakhulu kuba abathengi abathenga iipleyiti zereferensi bafuna amaxwebhu abanokuwanika abahloli babo ngaphandle komnxeba olandelayo.
Indawo Yokuqala Esebenzayo
Akukho nanye kwezi zinto efuna ukuhlaziywa kwelebhu. Qala ngenkqubo yokucoca, jonga apho ipleyiti ixhaswa khona xa ithelekiswa nendawo ekufanele ukuba ibekhona, kwaye ujonge ukuba yintoni ehleli kufutshane nayo evelisa ubushushu. Ukulungiswa okuncinci apha kuhlala kudlula uhlengahlengiso olusebenzayo, kwaye kubiza kakhulu kunesiganeko sokungasebenzi kwe-CMM esingacwangciswanga esibangelwa ngumphezulu wesalathiso ongakhange ucinge ukuba uyawuthandabuza.
