Mu dziko la uinjiniya wolondola kwambiri, kufunafuna micron imodzi kungatanthauze kusiyana pakati pa kupambana ndi kulephera. Kwa zaka zambiri, maziko a zida zamakina anali chitsulo chosatsutsika. Komabe, pamene mafakitale monga opanga ma semiconductor, metrology ya ndege, ndi ma micro-electronics akukankhira malire a "nano-scale," zofooka za mafelemu achitsulo zawonekera kwambiri. Masiku ano,makina oyambira a granite molondolayakhala ngati muyezo wabwino kwambiri kwa iwo omwe sangakwanitse kugonja pa kukhazikika.
Kusankha zinthu zoyenera pa chimango cha makina si nkhani yongofuna ndalama zokha, koma nkhani ya sayansi ya kapangidwe kake. Mainjiniya ku ZHHIMG akhala zaka zambiri akufufuza chifukwa chake zigawo za granite nthawi zonse zimagwira ntchito bwino kuposa chitsulo chachikhalidwe m'malo olondola kwambiri.
Kukhazikika kwa Dimensional ndi Kupsinjika Kwamkati: Wopha Mosamalitsa Chete
Chimodzi mwa ubwino waukulu wa granite kuposa chitsulo chopangidwa ndi chitsulo ndi kukhazikika kwake kwachilengedwe. Chitsulo chopangidwa ndi chitsulo, monga chinthu chachitsulo, chimakumana ndi kupsinjika kwakukulu mkati panthawi yopangidwa ndi kuzizira. Ngakhale pambuyo pa "zokometsera" kapena kutentha, kupsinjika kumeneku kumatha kutulutsidwa pang'onopang'ono pakatha miyezi kapena zaka, zomwe zimapangitsa kuti pakhale kupindika kwa microscopic. Mumaziko a granite a CMM olondola, nkhawa zotere sizilipo.
Granite ndi mwala wachilengedwe womwe wakhala ukupangidwa pansi pa nthaka kwa zaka mamiliyoni ambiri. Kapangidwe kake ka molekyulu kamakhala "komasuka" mwachibadwa. ZHHIMG ikasintha granite yosaphika kukhala chimango cha makina, timagwira ntchito ndi zinthu zomwe zafika kale pamlingo wake womaliza. Pa Makina Oyezera Ogwirizana (CMM), izi zikutanthauza kuti malo owunikira amakhalabe osalala komanso oona kwa zaka zambiri akugwira ntchito, kuonetsetsa kuti miyezo yomwe yatengedwa lero ikugwirizana bwino ndi yomwe yatengedwa zaka zambiri kuchokera pano.
Kudziwa Malo Otentha
Kukula kwa kutentha ndi mdani wa kulondola. Mu fakitale yodziwika bwino yopanga zinthu, kusinthasintha kwa kutentha sikungapeweke. Chitsulo chopangidwa ndi chitsulo chimakhala ndi kuchuluka kwa kutentha (CTE), zomwe zikutanthauza kuti chimakula ndikuchepa kwambiri ndi kusintha kwa kutentha.
Komabe, granite ili ndi CTE yotsika kwambiri - pafupifupi gawo limodzi mwa magawo atatu kuposa chitsulo chopangidwa ndi chitsulo. Makina akamagwiritsa ntchito maziko a granite olondola, sakhudzidwa kwambiri ndi kusintha kwa kutentha kwa chilengedwe. Kapangidwe kameneka kamachepetsa kufunika kwa kulimbitsa kutentha kochokera ku mapulogalamu ovuta ndikuwonetsetsa kuti mawonekedwe a makinawo azikhalabe osasinthika. Pamagawo monga kuyang'anira ma semiconductor, komwe zigawo zake zimakhala ndi kusinthasintha ngakhale kwa 0.1°C, granite imapereka "inertia" ya kutentha yomwe chitsulo sichingagwirizane nayo.
Kuchepetsa Kugwedezeka: Chinsinsi cha Kukhulupirika kwa Malo
Kulondola sikungokhala chete; koma ndi momwe makina amagwirira ntchito. Mota iliyonse, spindle, ndi actuator zimapanga kugwedezeka. Ngati chimango cha makina sichingathe kuyamwa kugwedezeka kumeneku, chimabwereranso ku chida kapena sensa, zomwe zimapangitsa kuti pamwamba pake pakhale phokoso loipa kapena phokoso loyezera.
Granite imachita bwino kwambiri pakuchepetsa kugwedezeka kwa zinthu. Kapangidwe kake kamkati kamagwira ntchito bwino kwambiri pochotsa mphamvu ya kinetic kuposa chitsulo chopangidwa ndi chitsulo. Kafukufuku akusonyeza kuti granite imatha kuchepetsa kugwedezeka kwa zinthu mpaka nthawi 10 mofulumira kuposa mafelemu achitsulo. Pogwiritsa ntchito kapangidwe ka granite, opanga amatha kupeza liwiro lalikulu la spindle komanso liwiro la scanning pa CMMs popanda kuwononga umphumphu wa deta. Imagwira ntchito ngati siponji yopanda phokoso, kunyowetsa "phokoso" la njira yopangira.
Kukana Kudzimbiritsa ndi Kukhala ndi Moyo Wautali
M'malo ambiri amafakitale, chinyezi, zoziziritsira, ndi nthunzi za mankhwala zimakhala zoopsa nthawi zonse ku zipangizo. Chitsulo chopangidwa ndi chitsulo chimafuna kusamalidwa nthawi zonse, kupenta, ndi kudzola mafuta kuti chipewe dzimbiri. Dzimbiri likayamba pamalo olondola, kulondola kwake kumachepa kwamuyaya.
Granite mwachilengedwe siiwononga zinthu ndipo siilimbana ndi asidi. Siichita dzimbiri, siisungunuka, kapena kuchita zinthu ndi mankhwala wamba a mafakitale. Izi zimapangitsa kutimaziko a granite a CMM olondolaNdi yabwino kwambiri m'zipinda zoyera komanso m'malo ochitira kafukufuku komwe ukhondo ndi kuyera kwa zinthu ndizofunikira kwambiri. Kuphatikiza apo, granite siigwiritsa ntchito maginito, zomwe zimapangitsa kuti pasakhale kusokonezana ndi masensa amagetsi kapena zida zogwirira ntchito zamaginito.
Kudzipereka kwa ZHHIMG pa Kuchita Bwino Kwambiri
Ku ZHHIMG, sitimangopeza miyala yokha; timapanga molondola. Kusintha kuchoka pa chidutswa cha gabbro wakuda kupita ku chipangizo chololera kwambiri kumaphatikizapo kuphatikiza kwa makina apamwamba a CNC ndi luso lakale lolumikiza ndi manja. Ngakhale makina amatha kutiyandikira, micron yomaliza ya flatness pa athumaziko a makina a granite olondolanthawi zambiri zimachitika chifukwa cha manja okhazikika a akatswiri athu odziwa bwino ntchito.
Njira yathu yowongolera khalidwe imagwiritsa ntchito ma laser interferometers kuti atsimikizire kuti milimita iliyonse ya sikweya pamwamba ikukwaniritsa mulingo womwe watchulidwa. Kaya tikupanga maziko akuluakulu a mamita 6 a gantry system kapena gawo lapadera la benchi yowunikira, nzeru zathu zimakhalabe zomwezo: maziko ndiye gawo lofunika kwambiri la makinawo.
Kutsiliza: Kumanga Tsogolo pa Granite
Pamene dziko lonse lapansi likusintha kukhala lochita zinthu zokha komanso lolondola kwambiri, kufunikira kwa maziko a makina okhazikika, odalirika, komanso osakonza zinthu kudzangokulirakulira. Ngakhale kuti chitsulo chopangidwa nthawi zonse chidzakhala ndi malo mu makina olemera komanso amphamvu kwambiri, tsogolo la metrology yapamwamba komanso makina ang'onoang'ono ndi la granite.
ZHHIMG ikupitilizabe kutsogolera kusinthaku, kupatsa msika wapadziko lonse lapansi mayankho a granite omwe amatsimikizira kukhazikika. Posankha granite, mainjiniya sakungosankha chinthu chokhacho; akusankha cholowa cholondola chomwe chimapirira nthawi ndi kutentha.
