Umhlahlandlela Wokulungisa Nokulungisa Ipuleti Lomphezulu Wegranite: Ipuleti lomphezulu wegranite elinembile lidinga imishini ekhethekile kanye nokugcinwa ukuze kuqinisekiswe ukunemba kwayo kanye nobude bayo. Ngaphambi Kokupholisha, ingxenye yegranite kumele iqale ukucutshungulwa komshini kanye nokulungiswa okuvundlile ngokusekelwe ezimisweni zokubeka unxantathu. Ngemva kokugaya okuvundlile, uma imishini ye-CNC ingakwazi ukufeza ukunemba okudingekayo—ngokuvamile ukufinyelela ukunemba kweBanga 0 (ukubekezelelana okungu-0.01mm/m njengoba kuchaziwe ku-DIN 876)—ukuqedwa ngesandla kuyadingeka ukuze kufinyelelwe amamaki aphezulu okunemba njengeBanga 00 (ukubekezelelana okungu-0.005mm/m ngokwezindinganiso ze-ASTM B89.3.7).
Inqubo yokugaya ihilela izinyathelo eziningana ezibalulekile. Okokuqala, ukugaya okuqinile kusungula ukuthamba okuyisisekelo, kulandelwe ukuqeda okuyingxenye kwesibili ukuze kususwe izimpawu zokugaya. Ukugaya okunembile, okuvame ukwenziwa ngesandla, kucwengisisa indawo ukuze kufezwe ukubekezelela ukuthamba okufiselekayo kanye nokuthamba kwendawo (inani likaRa elingu-0.32-0.63μm, lapho uRa emele ukuphambuka okulinganiselwe kwephrofayili yendawo). Okokugcina, ukuhlolwa okucophelelayo kuqinisekisa ukuhambisana nezindinganiso zobuchwepheshe, ngamaphuzu okulinganisa abekwe ngendlela efanele kuzo zonke izinhlangothi eziphambeneyo, imiphetho, kanye nemigqa ephakathi—ngokuvamile amaphuzu angu-10-50 kuye ngosayizi wepuleti—ukuqinisekisa ukuhlolwa kokunemba okufanayo.
Ukuphathwa nokufakwa kuthinta kakhulu ukunemba. Ngenxa yokuqina kwe-granite okungokwemvelo (ubulukhuni be-Mohs 6-7), ukuphakamisa okungafanele kungabangela ukuguquka okuhlala njalo. Ngezicelo ezibalulekile ezidinga ukunemba kwe-Grade 00, ukugoqa ngesandla ngemuva kokufakwa kubalulekile ukuze kubuyiselwe ukunemba okuphazamisekile ngesikhathi sokuthuthwa. Lokhu kunakwa emininingwaneni kuhlukanisa amapuleti obuso be-granite okunemba okuphezulu ezinhlotsheni ezijwayelekile ezenziwe ngomshini.
Imikhuba yokulungisa ithinta ngqo ukusebenza kanye nesikhathi sokuphila. Qala ngokuhlanza ngokuphelele usebenzisa izihlanzi ze-pH ezingathathi hlangothi—gwema izinto ezine-acidic ezingachoboza ubuso. Ukulinganisa minyaka yonke ngama-interferometer e-laser, alandelelwa ngokwezindinganiso ze-NIST, kuqinisekisa ukunemba okuqhubekayo. Lapho ubeka izinto zokusebenza, vumela ukulingana kokushisa (ngokuvamile imizuzu eyi-15-30) ukuvimbela amaphutha okulinganisa kusuka ekuhlukeni kokushisa. Ungalokothi ushelele izinto ezirhabaxa phezu kobuso, njengoba lokhu kungadala imihuzuko emincane ethinta ukuba yisicaba.
Iziqondiso ezifanele zokusebenzisa zifaka phakathi ukuhlonipha imikhawulo yomthwalo ukuze kuvinjelwe ukuguquka kwesakhiwo, ukugcina izimo zemvelo ezizinzile (izinga lokushisa 20±2°C, umswakama 50±5%), kanye nokusebenzisa imishini yokuphakamisa ezinikele ukugwema ukulimala kwendiza eqhekekile. Ngokungafani nezinye izinto zensimbi, ukuzinza kokushisa kwe-granite (0.01ppm/°C) kunciphisa amathonya emvelo, kodwa izinguquko zokushisa ezizumayo kufanele zigwenywe.
Njengethuluzi eliyisisekelo ekulinganisweni kokunemba, amapuleti obuso be-granite aqinisekisiwe (aqinisekiswe yi-ISO 17025) asebenza njengendinganiso yokubhekisela ekulinganisweni kobukhulu. Ukugcinwa kwawo kudinga umzamo omncane—ukumane usule ngendwangu engena-lint ngemva kokusetshenziswa—akudingeki ukumbozwa okukhethekile noma izinto zokugcoba. Ngokulandela lezi zinqubo zokulungisa nokunakekela, amapuleti obuso be-granite anembile anikeza ukusebenza okuthembekile amashumi eminyaka, okwenza abe yinto ebalulekile emalabhorethri okulinganisa, ekukhiqizweni kwezindiza, kanye nezicelo zobunjiniyela obunembile kakhulu.
