Matebulo opanga miyala ya granite omwe amagulitsidwa sizitsulo zolemetsa chabe pamiyendo yachitsulo-ndi maziko achete azitsulo zolondola. Tidawona masitolo ku North America ndi ku Europe akusintha mabenchi azitsulo zokhotakhota ndi malo ogwirira ntchito a granite - ndipo mkati mwa masiku 90, zokolola zawo zoyambirira zidalumpha pafupifupi 12%. Chifukwa chiyani? Chifukwa kukhazikika kwamafuta kumafunika kwambiri kuposa kukhazikika mukakhala ndi ± 0.005 ″ kulolerana pamabulaketi odinda kapena mapanelo odulidwa a laser.
Chifukwa Chake Granite—Osati Chitsulo Kapena Iron—Imapambana Pakupeka Padziko Lonse
Akatswiri ambiri amaganiza kuti "ntchito yolemetsa" imatanthauza chitsulo cholimba. Koma kulemera kokha sikuletsa kugwedezeka. Chiŵerengero cha granite damping ndi 3-5 × apamwamba kuposa chitsulo choponyedwa ndi 10 × apamwamba kuposa zitsulo zamapangidwe. M'mayesero athu afakitole, bulaketi yokhomeredwa ndi CNC yoyikidwa patebulo la granite la 3 ″ idawonetsa kumveka kocheperako kwa 68% pa 120 Hz kuposa kukhazikitsidwa komweko pazitsulo 2 ″ zowotcherera. Izi zimatanthawuza molunjika ku mbali zotsuka bwino, malo obwerezabwereza, ndi kukonzanso kochepa.
Granite imakananso kusuntha kwamafuta. Malo ogulitsira wamba amawona kutentha kwapansi kwa ± 8 ° C tsiku lililonse. Mabenchi achitsulo amakula/mgwirizano pa 12 µm/m·°C; granite imasuntha 0.5–0.8 µm/m·°C basi. Pamtunda wa 2-mita, ndiko kusintha kwachitsulo kwa 0.24 mm motsutsana ndi 0.02 mm mu granite-zokwanira kutaya kafukufuku wa CMM kapena kusokoneza imfa yopindika.
Sitikupangira ma granite m'malo otsika kwambiri - monga masiteshoni kapena ma hydraulic press floor. Koma poyang'anira, kusonkhanitsa, kugwedeza, ndi ntchito yolondola? Ndizosakambirana. Ndipo inde-imagwira ntchito mwachizolowezi zitsulo zachitsulo. Benchi yathu yoyeserera idapulumuka mizunguliro 1,200 yokoka zitsulo 12-gauge zoziziritsa kuzizira pamwamba pake ndi ziro zing'onozing'ono kapena kupukuta m'mphepete.
Zimene Ogula Amafunikira—Osati Zimene Timabuku Amalonjeza
"Matebulo opanga ma granite ogulitsidwa" nthawi zambiri amabisa zinthu zovuta. Izi ndi zomwe zimalekanitsa mabenchi ogwira ntchito ndi mapepala okwera mtengo:
Grade nkhani: ASTM C615 yokha ya Giredi A kapena B ya granite yakuda (mwachitsanzo, Absolute Black, Baltic Brown) imapereka kachulukidwe kosasinthika komanso kutsika pang'ono. "Zowoneka bwino za granite" zamalonda zimasweka pansi pa katundu wokhazikika. Kulekerera kwa flatness: Musalole chilichonse chomasuka kuposa ± 0.002" kupitirira mita imodzi - kapena ± 0.008" kupitirira mamita 4. Chilichonse chokulirapo chimapangitsa kuti pakhale kusokoneza panthawi ya clamping. Kukulitsa umphumphu: Miyendo iyenera kungirira mwala molunjika-osati m'malo odzaza ndi epoxy. Tawona matebulo atatu akulephera mkati mwa miyezi 18 chifukwa opanga amagwiritsa ntchito makina omatira okha. Kumaliza pamwamba: 60-80 grit honed ndiye mulingo woyenera. Kupukuta pagalasi kumawonetsa kuwala koma kumabisa zizindikiro; chomaliza kwambiri chimatha kugwedezeka ndikuvala mwachangu. Ogula ena amafunsa kuti: "Kodi ndingathe kuwotcherera pa izo?" Ayi—simungathe. Granite imasweka pamwamba pa 300 ° C. Koma inu akhoza khazikitsani ma welding jigs, zomangira pansi, ndi maziko a maginito motetezedwa. Ingosungani kutentha> 150 mm kutali.
Zogulitsa Zenizeni Zapadziko Lonse - Palibe Zopaka Shuga
Granite si zamatsenga. Lili ndi malire—ndipo kuwadziŵa kumateteza kulakwa kwakukulu.
Choyamba: kulemera kwa kutumiza. Tebulo la 2400 × 1200 × 76 mm limalemera ~ 1,450 kg. Izi zimafuna kulimbikitsa ma docks, ma jacks a pallet omwe adavotera 2,000 kg, komanso osachepera anayi ophunzitsidwa bwino kuti atsitse. Nthaŵi ina tinawona kasitomala akuyesa kukweza imodzi ndi forklift—anathyola zipilala ziŵiri ndi kuswa mwalawo m’njira yachilengedwe.
Chachiwiri: nthawi yoyika. Kukweza miyala ya granite sikuli ngati kutsekereza zitsulo. Mufunika mapazi osinthika, msinkhu wa makina ovomerezeka, ndi maola 2-4 osachepera - ngakhale pansi pa konkire. Thandizo losagwirizana limayambitsa kusweka kwa nkhawa pakapita nthawi.
Chachitatu: mtengo. Inde, matebulo a granite amawononga 2.3 × kuposa zitsulo zolemera kwambiri. Koma makasitomala athu amafotokoza kubweza m'miyezi 14 mpaka 18 kudzera muzitsulo zochepetsedwa, kuvomereza nkhani yoyamba mwachangu, komanso kutsika kwapang'onopang'ono kwa metrology. Wothandizira magalimoto a Tier-1 adadula kutsimikizira kwawo kwa CMM kuyambira sabata iliyonse mpaka kotala pambuyo posintha.
Mmene Mungatchulire—Popanda Kuwotchedwa
Osayitanitsa "tebulo la granite." Onjezani izi:
Zakuthupi: ASTM C615 Giredi A granite wakuda, wopangidwa ku India kapena ku Brazil (wotsimikizika kudzera pa satifiketi ya mphero) Makulidwe: Kutalika kwenikweni × m'lifupi × makulidwe, ndi kulolerana ± 0.5 mm Kusalala: Kutsimikiziridwa pa ASME B89.3.7, yonenedwa ngati kupatuka kwakukulu pamtunda wonse Kukwera: Zowonjezera zinayi za M16, 40 mm kuya, zokhazikika 100 mm kuchokera pakona iliyonse Malizitsani: 70-grit honed, m'mphepete mwake amachepetsedwa mpaka 1.5 mm radius Zolemba: Lipoti la calibration, satifiketi yazinthu, ndi pepala loyang'ana mozama likuphatikizidwa Botou Haijun Metal Products Co., Ltd. imamanga matebulo opangira miyala yamtengo wapatali kuzinthu zenizeni izi-osati monga zowonjezera, koma monga makina opangidwa ndi injiniya. Timaziphatikiza ndi mabulaketi athu okwera odinda bwino, mapazi osapanga chitsulo chosapanga dzimbiri, ndi mapadi oletsa kugwedezeka. Gome lililonse limayenda ndi data yodziwika ya QC-osati chomata.
Mawu Omaliza: Kulondola Kumayambira Pansi Pansi
Benchi yogwirira ntchito sipanga magawo. Koma malo osayendetsedwa bwino amatsimikizira kusinthasintha. Matebulo opanga miyala ya granite omwe amagulitsidwa amapereka ROI yoyezera momwe kubwereza, kukhazikika kwamafuta, komanso kukhazikika kwanthawi yayitali kumatanthawuza kupambana, osati mphamvu zokha. Ngati ndondomeko yanu ikugwira mwamphamvu kuposa ± 0.010 ″, imalekerera macheza osagwedezeka, kapena imafuna zaka zambiri zantchito popanda kukonzanso, granite sizosankha. Ndilo maziko.
Pitani ku haijunmetals.com kuti mupemphe chitsamba chowoneka bwino, muwunikenso zochitika zenizeni kuchokera kwamakasitomala a makina aulimi ndi zida zomangira, kapena konzekerani kuwunika kwaulere kwa DFM kwa projekiti yanu yotsatira yophatikiza benchi.
