Iitafile zokwenza i-Granite azigugi-zikhula. Siye sabona iiyunithi ezineminyaka eli-15 ubudala zisebenza ngokusebenzayo kwiivenkile ze-Tier-1 ze-automotive stamping e-Ohio naseJamani, zisabambe ± 0.002 ″ flatness ngapha kwe-8′ × 4′ umphezulu emva koqhagamshelwano lwemihla ngemihla kunye neetoni ezingama-30 zokucinezela iziqhoboshi kunye nentsimbi ekrazukileyo engenanto. Yiyo loo nto"iitafile ezenziwe ngegranite ezisetyenzisiweyo ezithengiswayo” ayilocandelo lezaphulelo—licebo lokuthenga elichanekileyo.
Kutheni iGranite—Kungeyontsimbi, Kungeyontsimbi—Isaphumelela Kwimveliso Yentsimbi Enyamezeleke Kakhulu
Uninzi lwabathengi luqala ngeendleko. Kodwa umbuzo wangempela ngulo: "ixabiso eliphantsi" lixabisa ntoni ezantsi? Siye salandela umkhondo weevenkile ezintathu zemisebenzi esembindini eziye zatshintsha kwiitafile zentsimbi ezidityanisiweyo zaza zasebenzisa iiyunithi zegranite. Zonke iinzuzo ezinokulinganiswa zixelwe-kungekhona kwixabiso lokufumana, kodwa ekunciphiseni umsebenzi. Enye ivenkile inqumle iimpazamo ze-part-fit nge-68% kwii-bracketassemblies ze-hydraulics yezolimo. Enye isuswe iiyure ze-11 / iveki yomgangatho womgangatho wezandla phambi kwe-CNC yokusika i-plasma.
Iinzuzo zeGranite zezomzimba, hayi ukuthengisa:
Ukwandiswa kwe-thermal engu-Zero: I-Coefficient ye-0.0000006 mm/mm/°C—izinzile kwiijingi ze-HVAC zamaxesha athile kunye nobushushu obuveliswa ngumatshini Ukushukuma kwendalo ukudambisa: Ithomalalisa iresonance esuka koomatshini boxinzelelo behydraulic obukufutshane kunayo nayiphi na indibaniselwano yobunjineli Umphezulu ongatshatisiyo, ongenamagnetic: Ibalulekile xa uphethe iphepha le-aluminiyam okanye izixhobo ezichanekileyo zomhlaba Ukuphindaphinda kwenqanaba leMicron: Yakube iqinisekisiwe, itafile yegranite exhaswe ngokufanelekileyo ibamba umgama omde kunokuba isatifikethi sayo sokulinganisa siphelelwa. Iiyunithi ezisetyenzisiweyo zigcina ezi zakhiwo ngokupheleleyo. Ngokungafaniyo nentsimbi, igranite ayidinwa. Ingqibelelo yayo ixhomekeke kuphela kwindlela eyaphathwa ngayo—kungekhona ukuba yahlala ixesha elide kangakanani kwindawo yokugcina iimpahla.
Eyona nto ibalulekileyo xa uthenga isetyenziswa-kwaye yintoni engayenziyo
Abanye abathengi bathe phithi ziziphene zokuhombisa: ukuqhekeka kweenwele kufutshane nencam, imingxunya emincinane ngenxa yamashumi eminyaka yokuba sesichengeni sokupholisa, okanye ukufiphala kweempawu zesixhobo. Ezo azifane zichaphazele umsebenzi. Yintoni *ebulala* ukusebenza-kwaye siqinisekisa kuyo yonke iyunithi esiyibambayo-yinkxaso yolwakhiwo lwemfezeko.
Sivavanya izinto ezintathu akukho luhlu lubonisa imifanekiso:
Ukuqina kwesakhelo sesiseko: Ngaba isakhelo sentsimbi sijijekile, siqhekekile, okanye sishiyiwe ngendlela engafanelekanga? Isiseko esigobileyo senza isiqinisekiso sokutya singabi nantsingiselo. Indawo yokunxiba: I-T-slot nuts kunye ne-threaded inserts zithobisa kunye nemijikelo ye-torque ephindaphindiweyo. Sithatha indawo yazo zonke izixhobo zokuqinisa izinto kwi-ISO 9001 specs ezinokulandeleka. Imbali yohlengahlengiso lomphezulu: Ngaba umnini wangaphambili uyigcinile ilog yeCMM? Ngaphandle kokuhlolwa okubhaliweyo okuthe tyaba rhoqo kwiinyanga ezili-12-18, cinga ukuba umphezulu uyakhukuliseka. Omnye umxhasi uphantse wamkela itafile “efana-entsha” 10′ × 5′—de iqela lethu le-metrology lifumane i-0.015″ i-sag kumbindi we-axis. Unobangela? Ukugcinwa okungafanelekanga: kufakwe ngokuthe tye ngaphandle kweereyili zenkxaso ezipheleleyo. I-Granite igoba phantsi kobunzima bayo ukuba ayixhaswanga. Loo yunithi yabuyela ekulungisweni. Awuyi kuwubona loo mngcipheko kwiifoto zesitokhwe.
Indima kaBotou Haijun-Hayi njengoMthengisi, kodwa njengeQela eliQinisekisayo
I-Botou Haijun Metal Products Co., Ltd. ayifaki okanye iphinde ithengise iitafile zegranite. Kodwa ngenxa yokuba abathengi bethu benza izibiyeli ezichaneke kakhulu kunye nezinto ezinesitampu *kwezo tafile-kwaye ngenxa yokuba sinikezela ngeenxalenye kwiinkampani ezizisebenzisayo-siye saphuhlisa ukuqonda okunzulu kokusebenza.
Iqela lethu lobunjineli lihlala lindwendwela amaziko abathengi apho iitafile zegranite zihlala ecaleni kweebhuleki zethu zeCNC kunye neeseli zokuwelda iirobhothi. Silinganise indlela i-gradients ezishisayo ezivela kwizixhobo ezikufutshane zichaphazela ukuzinza komhlaba. Senze imephu iindlela zothumelo lokungcangcazela ukusuka kwiicompressor ezibekwe emgangathweni ukuya kwimilenze yetafile. Kwaye siye sanceda abathengi ukuba babuyisele iiyunithi ezindala zegranite ngeenkqubo zale mihla zemodyuli ye-T-slot ehambelana nemigangatho yanamhlanje yokulungisa.
Ukuba uvavanya itafile yokwenziwa kwegranite esetyenzisiweyo, cela:
Ingxelo epheleleyo ye-CMM-hayi nje "ukuphaphatheka ngaphakathi kwe-spec," kodwa iimephu ezitenxileyo zokwenyani (ulungelelwaniso lwe-X/Y/Z) Iifoto ze-underside ebonisa ingqibelelo ye-weld, i-shimming, kunye nemeko yokulinganisa iinyawo Uxwebhu lwamaxesha adlulileyo ohlengahlengiso kunye neendlela (i-laser interferometer vs. flats optical) Ezo nkcukacha zahlula ii-asethi ezingqinisiswe yintsimi kubunzima bamaphepha abizayo.
Ingcamango yokugqibela: Ukuchaneka akuthengwanga-Kuqinisekisiwe, emva koko kugcinwe
“Iitafile ezenziwe ngegranite ezisetyenzisiweyo ezithengiswayoElona xabiso liphantsi lesitikha lidla ngokufihla elona xabiso liphakamileyo lobomi bonke: ukusebenza ngokutsha, izinto ezilahliweyo, ukuyilwa ngokutsha kwezinto, kunye nokulibaziseka kwemveliso okubangelwa kukukhukuliseka komhlaba.
Isibonakaliso esinamandla sexabiso asikho ubudala okanye ipolishi-ngamaxwebhu. Itheyibhile esetyenziswe kakuhle ene-12 yeminyaka ye-CMM yelogs ibetha iyunithi "engaphathwanga" enembali ye-metrology engu-0. IGranite ayixoki. Kodwa abantu ngamanye amaxesha benza-malunga neemeko zokugcina, imbali yomthwalo, okanye umonakalo wangaphambili.
Phambi kokuba usayine, cela idata yomlinganiselo ekrwada—hayi izishwankathelo. Buza ukuba iyunithi yahanjiswa njani kwaye yaxhaswa njani ngexesha lokugqibela. Qinisekisa iinkcukacha zetorque yendawo ye-ankile zihambelana nenkqubo yakho yokulungisa. Kwaye ukuba umthengisi akakwazi ukubonelela ngemephu ye-flatness yamva nje kunye namanqaku okulungelelanisa, hamba. Kukho ukhetho olungcono.
Ukuqina kokwenyani akukho malunga nokusinda ixesha. Imalunga nokusinda ekuphononongweni.
