Izinto ekufuneka ziqwalaselwe xa ukhetha
Xa ukhetha iqonga legranite, kufuneka ulandele imigaqo "yokuchaneka kokuhambelana nesicelo, ubungakanani obuhambelana nomsebenzi, kunye nesiqinisekiso sokuqinisekisa ukuthotyelwa kwemithetho." Oku kulandelayo kuchaza iikhrayitheriya zokukhetha eziphambili kwiimbono ezintathu eziphambili:
Inqanaba lokuchaneka: Ukuthelekiswa kwemeko ethile kwiilebhu nakwiiworkshops
Amanqanaba ahlukeneyo okuchaneka ahambelana neemeko ezahlukeneyo zesicelo, kwaye ukhetho kufuneka lusekelwe kwiimfuno zokuchaneka kwendawo yokusebenza:
Iilabhoratri/Amagumbi okuhlola umgangatho: Amanqaku acetyiswayo yiKlasi 00 (ukusebenza ngokuchanekileyo kakhulu) okanye iKlasi AA (ukuchaneka kwe-0.005 mm). Ezi zifanelekile kwizicelo ezichanekileyo kakhulu ezifana nokulinganisa i-metrology kunye nokuhlolwa kwe-optical, njengeeplatifomu zesalathiso zoomatshini bokulinganisa abadibeneyo (ii-CMM).
Iindawo zokusebenzela/zeMveliso: Ukukhetha iKlasi 0 okanye iKlasi B (ukuchaneka kwe-0.025 mm) kunokuhlangabezana neemfuno zokuhlolwa ngokubanzi kwemisebenzi, njengokuqinisekiswa kobukhulu beendawo ezenziwe ngomatshini ze-CNC, ngelixa kulungelelaniswa ukuqina kunye nokusebenza kakuhle kweendleko. Ubungakanani: Ukusuka kwiSicwangciso seNdawo esiQhelekileyo ukuya kwiSicwangciso seNdawo esenziwe ngokwezifiso
Ubungakanani beplatifomu kufuneka buhlangabezane neemfuno zokubekwa kwendawo yokusebenza kunye nendawo yokusebenza:
Ifomula Esisiseko: Indawo yeplatifomu kufuneka ibe nkulu ngama-20% kuneyona ndawo inkulu yokusebenza ehlolwayo, nto leyo evumela ukuba kubekho indawo evulekileyo. Umzekelo, ukuhlola indawo yokusebenza engama-500×600 mm, kucetyiswa ubungakanani obuyi-600×720 mm nangaphezulu.
Ubungakanani obuqhelekileyo: Ubungakanani obuqhelekileyo buqala kwi-300×200×60 mm (encinci) ukuya kwi-48×96×10 intshi (enkulu). Ubungakanani obuqhelekileyo buqala kwi-400×400 mm ukuya kwi-6000×3000 mm buyafumaneka kwizicelo ezikhethekileyo.
Iimpawu ezongezelelweyo: Khetha kwi-T-slots, imingxunya enemisonto, okanye uyilo lomphetho (olufana ne-0-ledge kunye ne-4-ledge) ukuphucula ukuguquguquka kokufakwa kwezixhobo.
Isiqinisekiso kunye nokuThotyelwa kweMithetho: Ukuqinisekiswa okuphindwe kabini kokuthunyelwa kwamanye amazwe kunye nomgangatho
Isiqinisekiso Esiphambili: Ukuthunyelwa kwamanye amazwe kwiimarike zaseYurophu naseMelika kufuna ukuba ababoneleli banike isatifikethi se-ISO 17025 esinde, kubandakanya idatha yokulinganisa, ukungaqiniseki, kunye nezinye iiparameter eziphambili, ukuze kuthintelwe ukulibaziseka kokususwa kwempahla ngenxa yamaxwebhu angaphelelanga. Imigangatho Eyongeziweyo: Ukuze ufumane umgangatho osisiseko, jonga imigangatho efana ne-DIN 876 kunye ne-JIS ukuqinisekisa ukuba ukunyamezelana kokuthe tyaba (umz., iBanga 00 ± 0.000075 intshi) kunye noxinano lwezinto (igranite emnyama ikhethwa ngenxa yesakhiwo sayo esixineneyo kunye nokumelana nokuguquguquka) iyahlangabezana nemigangatho.
Ukhetho oluKhawulezayo lweReferensi
Izicelo zelebhu ezichanekileyo kakhulu: Ibanga 00/AA + 20% enkulu kune-workpiece + isiqinisekiso se-ISO 17025
Uvavanyo lweworkshop oluqhelekileyo: Ibanga 0/B + ubukhulu obuqhelekileyo (umz., ii-intshi ezingama-48×60) + ukuthobela i-DIN/JIS
Ukuthumela kwamanye amazwe eYurophu nase-United States: Isatifikethi se-ISO 17025 eside siyimfuneko ukuze kuthintelwe iingozi zokususwa kwerhafu
Ngokuthelekisa ngokuchanekileyo, ukubala ngokwemilinganiselo yesayensi, kunye nokuqinisekiswa okungqongqo kunye nesatifikethi, siqinisekisa ukuba amaqonga egranite ayahlangabezana neemfuno zemveliso kunye nemigangatho yokuthobela uthotho lweenkonzo zehlabathi.
Iingcebiso zoLondolozo kunye noLungiso
Ukusebenza ngokuchanekileyo kwamaqonga egranite kuxhomekeke kwinkqubo yokugcinwa kwesayensi kunye nokulinganisa. Oku kulandelayo kunika ulwalathiso lobuchwephesha kwiimbono ezintathu: ukusetyenziswa kwemihla ngemihla, ukugcinwa kwexesha elide, kunye nokuqinisekiswa kokuchaneka, ukuqinisekisa ukuthembeka okuqhubekayo kwesiseko sokulinganisa.
Ukugcinwa Kwemihla Ngemihla: Ukucoca Nokukhusela Amanqaku Aphambili
Iinkqubo zokucoca zisisiseko sokugcina ukuchaneka. Ngaphambi kokusebenzisa, qiniseka ukuba umphezulu awunamabala. Sicebisa ukusula ngamanzi angama-50% kunye nesisombululo se-isopropyl alcohol esingama-50%. Yomisa ngelaphu elithambileyo okanye itawuli yephepha ukuze ungonakalisi umphezulu wegranite ngezicoci ezine-asidi okanye iimveliso ezirhabaxa. Ngaphambi kokubeka iindawo, hlikihla ngobunono ngamatye ukuze ususe ii-burrs okanye imiphetho ebukhali. Hlikihla amatye kunye phambi kokusebenzisa ukucoca iqonga ukuze uthintele ukungcola ekulikrweleni. Kubalulekile: Akukho lubricant ifunekayo, njengoko ifilimu yeoyile iya kuchaphazela ngqo ukuchaneka kokulinganisa.
Iingxaki Zokugcinwa Kwemihla ngemihla
Musa ukusebenzisa izicoci ezine-ammonia ezifana neWindex (ezinokonakalisa umphezulu).
Ziphephe iimpembelelo zezinto ezinzima okanye ukurhuqa ngqo ngezixhobo zesinyithi.
Emva kokucoca, qiniseka ukuba womile kakuhle ukuze kungabikho mabala aseleyo emanzini.
Ukugcinwa Kwexesha Elide: Ukulwa Nokuguquguquka Nokuthintela Uthuli
Xa ungasetyenziswa, thabatha amanyathelo amabini okukhusela: Sicebisa ukuba ugqume umphezulu ngeplywood eyi-1/8-1/2 intshi efakwe i-felt okanye irabha, okanye isigqubuthelo sothuli esikhethekileyo, ukuze ungabi naluthuli kunye nokuqhekeka ngengozi. Indlela yokuxhasa kufuneka ihambelane ngokungqongqo nemigaqo ye-federal GGG-P-463C, isebenzise amanqaku amathathu azinzileyo ezantsi ukuqinisekisa ukusasazwa komthwalo okufanayo kunye nokunciphisa umngcipheko wokuguquka kokuwa. Amanqaku okuxhasa kufuneka ahambelane neempawu ezisezantsi kweqonga.
Isiqinisekiso sokuchaneka: Ixesha lokulinganisa kunye neNkqubo yeSatifikethi
Kucetyiswa ukuba kwenziwe uhlengahlengiso lonyaka ukuqinisekisa ukuba impazamo yokuba tyaba ihlala ihambelana nomgangatho wokuqala. Uhlengahlengiso kufuneka lwenziwe kwindawo elawulwayo kubushushu obungaguqukiyo obuyi-20°C kunye nomswakama ukuze kuthintelwe ukuthambekela kobushushu okanye ukuhamba komoya okunokuphazamisana neziphumo zokulinganisa.
Kwisiqinisekiso, onke amaqonga eza nesatifikethi sokulinganisa esilandelelwa yi-NIST okanye imigangatho efanayo yamazwe ngamazwe, okuqinisekisa ukuba i-flat kunye ne-repeatable iyaphindaphindeka. Kwizicelo ezichanekileyo ezifana ne-aerospace, iinkonzo ezongezelelweyo zokulinganisa ze-ISO 17025 ezivunyiweyo yi-UKAS/ANAB zinokucelwa, ukuphucula ukuthotyelwa komgangatho ngokuvunywa ngumntu wesithathu.
Iingcebiso zoLungiso
Qinisekisa ukuba isatifikethi sokulinganisa siyasebenza ngaphambi kokuba uyisebenzise okokuqala.
Ukulungiswa kwakhona kuyadingeka emva kokugaywa kwakhona okanye ukusetyenziswa kwentsimi (ngokuvumelana ne-ASME B89.3.7).
Kucetyiswa ukuba kusetyenziswe umenzi wokuqala okanye umboneleli wenkonzo ogunyazisiweyo ukuze kulungiswe ukuthintela ukulahleka okusisigxina kokuchaneka ngenxa yokusebenza okungekho sesikweni.
La manyathelo aqinisekisa ukuba iqonga legranite ligcina uzinzo lokulinganisa kwinqanaba le-micron kwixesha lokusebenza elingaphezu kweminyaka eli-10, libonelela ngomlinganiselo oqhubekayo nothembekileyo kwizicelo ezinje ngokuhlolwa kwecandelo leenqwelo moya kunye nokuveliswa kokubumba okuchanekileyo.
