Izinto Okufanele Uzicabangele Zokukhetha
Uma ukhetha ipulatifomu ye-granite, kufanele unamathele ezimisweni "zokunemba okufanelana nohlelo lokusebenza, usayizi ovumelana nomsebenzi, kanye nesitifiketi esiqinisekisa ukuhambisana." Lokhu okulandelayo kuchaza izindlela zokukhetha ezibalulekile ezivela emibonweni emithathu eyinhloko:
Izinga Lokunemba: Ukufaniswa Kwesimo Esiqondile KwamaLabhorethri Nama-Workshops
Amazinga ahlukene okunemba ahambisana nezimo ezahlukene zohlelo lokusebenza, futhi ukukhetha kufanele kusekelwe ezidingweni zokunemba zendawo yokusebenza:
Amalabhorethri/Amagumbi Okuhlola Ikhwalithi: Amamaki anconywayo yi-Class 00 (ukusebenza okunembile kakhulu) noma i-Class AA (ukunemba okungu-0.005 mm). Lawa afanele ukusetshenziswa okunembile kakhulu njengokulinganiswa kwe-metrology kanye nokuhlolwa kwe-optical, njengezinkundla zokubhekisela zemishini yokulinganisa ehlanganisiwe (ama-CMM).
Izindawo Zokusebenzela/Zokukhiqiza: Ukukhetha iKlasi 0 noma iKlasi B (ukunemba okungu-0.025 mm) kungahlangabezana nezidingo zokuhlolwa kwezingxenye zomsebenzi ezijwayelekile, njengokuqinisekiswa kobukhulu bezingxenye ezenziwe ngomshini we-CNC, ngenkathi kulinganiswa ukuqina kanye nokusebenza kahle kwezindleko. Osayizi: Kusukela Ekuhleleni Kwesikhala Okujwayelekile kuya Kokwenziwe Ngokwezifiso
Usayizi wepulatifomu kumele uhlangabezane nezidingo zokubekwa kwezingxenye zokusebenza kanye nendawo yokusebenza:
Ifomula Eyisisekelo: Indawo yesikhulumi kufanele ibe nkulu ngo-20% kunengxenye enkulu kunazo zonke ehlolwayo, okuvumela ukucaciswa kwemingcele. Isibonelo, ukuhlola ingxenye yokusebenza engu-500×600 mm, kunconywa usayizi ongu-600×720 mm noma ngaphezulu.
Osayizi Abavamile: Osayizi abajwayelekile basukela ku-300×200×60 mm (abancane) kuya ku-48×96×10 inches (abakhulu). Osayizi abangokwezifiso kusukela ku-400×400 mm kuya ku-6000×3000 mm bayatholakala kuzinhlelo zokusebenza ezikhethekile.
Izici Ezengeziwe: Khetha kusuka kuma-T-slots, imigodi enezintambo, noma imiklamo yomphetho (njenge-0-ledge kanye ne-4-ledge) ukuze uthuthukise ukuguquguquka kokufakwa kwe-fixture.
Isitifiketi Nokuhambisana Nemithetho: Isiqinisekiso Esiphindwe Kabili Sokuthunyelwa Kwempahla Ngaphandle kanye Nekhwalithi
Isitifiketi Esiyinhloko: Ukuthunyelwa kwamanye amazwe ezimakethe zaseYurophu naseMelika kudinga ukuthi abaphakeli bahlinzeke ngesitifiketi se-ISO 17025 eside, okuhlanganisa idatha yokulinganisa, ukungaqiniseki, kanye nezinye izilinganiso ezibalulekile, ukuze kugwenywe ukubambezeleka kokukhishwa kwempahla ngenxa yokubhalwa okungaphelele. Izindinganiso Ezengeziwe: Ukuze uthole ikhwalithi eyisisekelo, bheka izindinganiso ezifana ne-DIN 876 kanye ne-JIS ukuqinisekisa ukuthi ukubekezelelana kokuthamba (isb., Ibanga 00 ±0.000075 amayintshi) kanye nobuningi bezinto ezibonakalayo (i-granite emnyama iyathandwa ngenxa yesakhiwo sayo esiminyene kanye nokumelana nokuguquguquka) kuyahlangabezana nezindinganiso.
Ireferensi Esheshayo Yokukhetha
Izicelo zelebhu ezinembe kakhulu: Ibanga 00/AA + 20% likhulu kune-workpiece + isitifiketi se-ISO 17025
Ukuhlolwa kwe-workshop okuvamile: Ibanga 0/B + ubukhulu obujwayelekile (isb., amasentimitha angu-48×60) + ukuhambisana ne-DIN/JIS
Ukuthumela kwamanye amazwe eYurophu nase-United States: Isitifiketi se-ISO 17025 eside siyimpoqo ukuze kugwenywe izingozi zokukhishwa kwempahla
Ngokuqhathanisa okunembile, izibalo zesayensi, kanye nokuqinisekiswa okuqinile kanye nesitifiketi, siqinisekisa ukuthi amapulatifomu e-granite ahlangabezana nezidingo zokukhiqiza kanye nezindinganiso zokuhambisana nochungechunge lokuhlinzekwa komhlaba wonke.
Izincomo Zokulungisa Nokulinganisa
Ukusebenza ngokunemba kwamapulatifomu e-granite kuncike ohlelweni lokugcinwa nokulinganisa lwesayensi. Lokhu okulandelayo kunikeza isiqondiso sobungcweti kusuka emibonweni emithathu: ukusetshenziswa kwansuku zonke, isitoreji sesikhathi eside, kanye nokuqinisekiswa kokunemba, ukuqinisekisa ukuthembeka okuqhubekayo kwesisekelo sokulinganisa.
Ukugcinwa Kwansuku Zonke: Ukuhlanza Nokuvikela Amaphuzu Ayisihluthulelo
Izinqubo zokuhlanza ziyisisekelo sokugcina ukunemba. Ngaphambi kokusebenzisa, qiniseka ukuthi indawo ayinamabala. Sincoma ukusula ngamanzi angu-50% kanye nesisombululo se-isopropyl alcohol esingu-50%. Yomisa ngendwangu ethambile noma ngethawula lephepha ukuze ugweme ukulimaza indawo ye-granite ngezihlanzi ezine-acidic noma imikhiqizo yokuhudula. Ngaphambi kokubeka izingxenye, hlikihla kancane ngamatshe ukuze ususe ama-burrs noma imiphetho ebukhali. Hlikihla amatshe ndawonye ngaphambi kokusebenzisa ukuze uhlanze ipulatifomu ukuze uvimbele ukungcola ukuthi kungaklwebhi. Okubalulekile: Akukho lubricant edingekayo, njengoba ifilimu kawoyela izothinta ngqo ukunemba kokulinganisa.
Ama-Taboo Okulungisa Kwansuku Zonke
Ungasebenzisi izihlanzi eziqukethe i-ammonia njenge-Windex (engase igqwalise indawo).
Gwema ukushayisana nezinto ezisindayo noma ukuhudula ngqo ngamathuluzi ensimbi.
Ngemva kokuhlanza, qiniseka ukuthi womisa kahle ukuze uvimbele amabala amanzi asele.
Isitoreji Sesikhathi Eside: Ukuvimbela Ukuguquka Nokuvinjelwa Kothuli
Uma ingasetshenziswa, thatha izinyathelo ezimbili zokuvikela: Sincoma ukumboza indawo nge-plywood engu-1/8-1/2 intshi efakwe i-felt noma irabha, noma isembozo sothuli esikhethekile, ukuze uyihlukanise nothuli kanye namaqhubu angengozi. Indlela yokusekela kumele ihambisane ngokuqinile nencazelo kahulumeni i-GGG-P-463C, isebenzisa amaphuzu amathathu aqinile phansi ukuqinisekisa ukusatshalaliswa komthwalo okufanayo nokunciphisa ingozi yokuguquguquka kokuwa. Amaphuzu okusekela kumele ahambisane nezimpawu ezingezansi kwepulatifomu.
Isiqinisekiso Sokunemba: Isikhathi Sokulinganisa kanye Nohlelo Lokuqinisekisa
Kunconywa ukulinganisa minyaka yonke ukuqinisekisa ukuthi iphutha lokuba yisicaba lihlala lihambisana nezindinganiso zokuqala. Ukulinganisa kumele kwenziwe endaweni elawulwayo ekushiseni okungaguquki okungu-20°C kanye nomswakama ukuze kugwenywe ukwehla kwezinga lokushisa noma ukuhamba komoya okungaphazamisa imiphumela yokulinganisa.
Ukuze kuqinisekiswe, wonke amapulatifomu eza nesitifiketi sokulinganisa esilandelwa yi-NIST noma amazinga alinganayo omhlaba, okuqinisekisa ukuthi i-flat kanye ne-repeatable iyaphindeka. Ukuze kusetshenziswe izinhlelo zokusebenza ezinembe kakhulu njenge-aerospace, kungacelwa izinsizakalo ezengeziwe zokulinganisa ze-ISO 17025 eziqinisekiswe yi-UKAS/ANAB, okuthuthukisa ukuhambisana nekhwalithi ngokugunyazwa yinkampani yangaphandle.
Amathiphu Okulinganisa
Qinisekisa ukuthi isitifiketi sokulinganisa siyasebenza ngaphambi kokusebenzisa okokuqala.
Ukulinganisa kabusha kuyadingeka ngemva kokugaya kabusha noma ukusetshenziswa ensimini (ngokuvumelana ne-ASME B89.3.7).
Kunconywa ukusebenzisa umenzi wokuqala noma umhlinzeki wesevisi ogunyaziwe ukuze kulinganiswe ukuze kugwenywe ukulahlekelwa unomphela kokunemba ngenxa yokusebenza okungekhona kochwepheshe.
Lezi zinyathelo ziqinisekisa ukuthi ipulatifomu ye-granite igcina ukuzinza kokulinganisa kwezinga le-micron phakathi nokuphila kwenkonzo okungaphezu kweminyaka eyi-10, okuhlinzeka ngokulinganisa okuqhubekayo nokwethembekile kwezicelo ezifana nokuhlolwa kwezingxenye zezindiza kanye nokukhiqizwa kwesikhunta ngokunemba.
