Kodi Ubwino Wotani wa Ukadaulo Wokonza Maziko Oyimirira a Granite ndi Ma Groove Okwera Ndi Wotani?

Mu njira zamakono, maziko ndi ma adapter achitsulo amapangidwa padera ndikusonkhanitsidwa ndi ma bolts, zomwe zimayambitsa kupotoka kwa malo ophatikizika, kusakhazikika bwino kwa ma assembly ndi kusintha kolimba ngati zolakwika za superposition. Ndi ukadaulo wa ZHHIMG wopangira grooving, datum yoyika ma grooves ndi nkhope yayikulu ya datum ya vertical base imachokera ku granite substrate yomweyi yokhala ndi ma references ofanana, ndipo palibe ma adapter owonjezera achitsulo omwe amafunikira. Kulekerera malo a groove ndi perpendicularity ya khoma la groove zimapangidwa mu pass imodzi pamodzi ndi base datum, zomwe zimachepetsa kwambiri zolakwika za Abbe. Ndi yoyenera makamaka zida zodziwika bwino monga zida zoyezera zithunzi ndi zida zowunikira za AOI, ndipo imakulitsa kwambiri kulondola kwa geometry pambuyo pa kusonkhana kwathunthu kwa makina.

Granite ndi chinthu chophwanyika. Pamene ma adapter achitsulo osiyana amamangiriridwa ndi mabolt, mphamvu ya bolt imayambitsa kupsinjika kwapafupi pamalo olumikizirana. Pakasinthidwa katundu kwa nthawi yayitali, kusokonekera kwa kupsinjika kapena kusweka kwa miyala yobisika kungachitike. Kuyika chitoliro chimodzi kumaphatikiza ma interface oyika mkati mwa granite substrate; mphamvu imagawidwa mofanana pamunsi ponse popanda kulumikizana pakati pa zinthu zosiyana. Kuphatikiza ndi granite yakuda yolimba kwambiri, kulimba konse kumawongoleredwa kwambiri. Kusokonekera kwa micro-deformation yapafupi sikuchitika kawirikawiri chifukwa cha mphamvu yamphamvu yachangu komanso mikhalidwe yogwira ntchito yolemera nthawi zonse kuti pakhale kukhazikika kwa kapangidwe ka nthawi yayitali.

Kukonza zinthu mopanda mphamvu kumapangitsa kuti zinthu zisamayende bwino mozungulira malo otseguka. Opanga ambiri amapereka zinthu zomalizidwa atangomaliza kukonza zinthu mopanda mphamvu. Pambuyo potumiza, kumasula zinthu mopanda mphamvu kumabweretsa kusiyana kwa mipata ndi kukhazikika kwa maziko. ZHHIMG ikutsatira njira yonse yogwirira ntchito: kukonza zinthu mopanda mphamvu ndi kukhazikika bwino ndi ndalama zosungiramo zinthu → kukalamba kwa magawo ambiri m'munda wamatabwa ndi malo ogwirira ntchito otentha nthawi zonse kuti athetse kupsinjika kwa kudula kuchokera ku kukonza zinthu mopanda mphamvu → kupukuta bwino ndi kulumikiza ndi manja. Pazigawo zazikulu, kuchepetsa kupsinjika kwachilengedwe kwa nthawi yayitali kumachitika pamalo opangira zinthu okwana 200 000 m² ndi malo osungiramo zinthu a miyala osaphika okwana 20 000 m². Malo ogwirira ntchito otentha nthawi zonse ndi chinyezi nthawi zonse okwana 10 000 m² amachotsa kusokonezeka kwa chilengedwe, kuonetsetsa kuti malo ozungulira ali ndi malo ozungulira, kufanana kwa makoma a mpanda ndi kukhazikika kwa maziko popanda kugwedezeka nthawi ndikutsatira zofunikira zautumiki wa nthawi yayitali wa miyezo yapadziko lonse lapansi monga DIN ndi ASME.                                                                        

Opanga ambiri amachita kugaya kosavuta akamaliza kupukuta, zomwe zimapangitsa kuti makasitomala asamakome bwino komanso kuti asamakome kwambiri pamalopo. Popeza ali ndi makina akuluakulu opukutira zinthu a NT komanso akatswiri opukutira zinthu omwe ali ndi luso loposa zaka 30 lopukutira zinthu, ZHHIMG imagwiritsa ntchito kugaya kolondola pamakoma onse am'mbali ndi pansi pa malo opukutira zinthu kuti akwaniritse kulondola kwa micron level. Kukula kwa groove, kufanana, ndi kulolerana kwa malo zimawunikidwa mokwanira pogwiritsa ntchito Renishaw laser interferometers, WYLER electronic levels ndi zida zina, zomwe zida zawo zoyezera zimatha kutsatiridwa ku National Metrology Institute. Makasitomala amatha kuyika mwachindunji ma positioning blocks, air bearing assemblies ndi linear modules akalandira katundu, kudula malo opukutira zinthu komanso mobwerezabwereza commissioning cycles ndikufupikitsa nthawi yonse yopangira makina.

Kuphatikiza kosiyanasiyana kwa ma groove oyika, ma groove oyikapo, ndi ma T-slots kumatha kupangidwa malinga ndi zojambula, pamodzi ndi ma countersink, ma embed thread inserts ndi ma pin holes. Mothandizidwa ndi mphamvu ya fakitale ya 20 m kutalika ndi 100 ton single piece components, grooving ya piece imodzi ikhoza kuchitika pa ma pedestal ang'onoang'ono ndi apakatikati olunjika a zida zoyezera za 2-D komanso maziko akuluakulu olunjika a semiconductor ndi zida zatsopano zowunikira mphamvu. Kusonkhana kogawanika kumapewedwa pamodzi ndi zolakwika zomwe zimachitika chifukwa cha msoko. Ma granite air-bearing units, ma optical modules, ndi zida zowunikira zimatha kuyikidwa mwachindunji pamaziko kuti zitheke kutumiza nthawi imodzi ndikuchepetsa ndalama zogulira ndi kuyang'anira zida za makasitomala.

Mizere ya adaputala yachitsulo yomwe yayikidwa pambuyo poyikamo imasintha momwe granite imakhalira yonyowa; kugwedezeka kwa zigawo zachitsulo kumalimbikitsa kugwedezeka kwa zida. Kugwedeza kwa chidutswa chimodzi kumachotsa miyala yochepa yokha ndikusunga mphamvu yabwino kwambiri yonyowa ya granite wakuda. Pogwiritsa ntchito mayendedwe obwerezabwereza mofulumira, kugwira ntchito kwa laser pulse ndi kusanthula pafupipafupi kwa ma probe owunikira, kugwedezeka kumawola mwachangu kuti kuchepetse kusokonezeka kwa resonance ndikutsimikizira kubwerezabwereza kwa zithunzi za optical ndi deta yoyezera miyeso. Kulondola kokhazikika kwa malo omangidwira pamizere kumatha kusungidwa ngakhale m'ma workshop opanga ndi kusokonezeka kwa kugwedezeka kwakunja.

Mizere yonse imapangidwa mokhazikika pa granite substrate popanda chiopsezo cha dzimbiri, okosijeni kapena kuchotsedwa kwa ma adapter achitsulo pamwamba. Mizereyi imawonetsedwa ku zotsukira m'ma workshop a semiconductor ndi mitundu yosiyanasiyana m'mafakitale a lithiamu battery, ndipo sizingawononge kapena kuipitsa malo a datum. Kusamalira chophimba choletsa dzimbiri sikofunikira. Mizereyi ndi yosavuta kuyeretsa ndipo nthawi zambiri siingasonkhanitse zinyalala zomwe zingadetse zinthu zosuntha, zomwe zimawonjezera nthawi yogwira ntchito ya zida zonse ndikugwirira ntchito nthawi yayitali m'ma workshop opanda fumbi komanso ma laboratories a metrology.
