Mumaindasitiri ane magadzirirwo akanyatsojeka—kubva mundege nemotokari kusvika kumagetsi nemidziyo inorema—kuda kwekururama hakungodziki nekuti zvikamu zvacho zvinokura. Asi, zvinhu zvikuru zvakaita sema turbine housings, gearbox casings, kana structural weldments zvinowanzova ne geometric tolerances dzakasimba zvichienderana nehukuru hwazvo, zvichiita kuti kuyerwa kwakavimbika kusangova kwakaoma chete, asi kuve kwakakosha. Asi, nzvimbo dzakawanda dzinotarisa chinhu chimwe chete chakakosha pakuongorora zvikamu zvikuru: kugadzikana uye kutsamira kwenzvimbo yekutarisa yavari kushandisa. Kana uri kushanda ne granite surface plate yakakura, watonzwisisa kukosha kwayo—asi uri kuwana kushanda kwakazara kwainokwanisa kuita here?
Chokwadi ndechekuti,ndiro yegranitechete hazvina kukwana. Pasina rutsigiro rwakakodzera, kudzora zvakatipoteredza, uye kubatanidzwa mukushanda kwemetrology kwakagadziriswa, kunyangwe slab yepamusoro-soro inogona kushanda zvisina kunaka—kana kuti zvakatoipa, kuunza zvikanganiso zvakavanzika. Ndosaka vagadziri vanotungamira vasingangotengi plate chete; vanoisa mari musystem yakazara—kunyanya, kunyatsojekandiro yepamusoro yegraniteine chigadziko chakagadzirwa kuti chigadzikane, chisvike nyore, uye chigare kwenguva refu. Nekuti kana plate yako ikadonha zvishoma pasi pehuremu hwayo kana kuti ikadedera kubva kumichina iri pedyo, kuverenga kwega kwega kwehurefu, kutarisa kwega kwega kwesquareness, uye kurongeka kwega kwega kunova kusingafungidzike.
Granite yave iri mwero wepamusoro wekutarisa nzvimbo dzakarurama kwemakore anopfuura makumi manomwe, uye nechikonzero chakanaka chesainzi. Muumbirwo wayo mutema usina maburi, une ganda rakatsetseka, unopa kugadzikana kwakanyanya, kuwedzera kushoma kwekupisa (kazhinji 6–8 µm pa mita imwe neimwe pa °C), uye kudzikamisa kwechisikigo kwemagetsi - zvese izvi zvakakosha pakusimbisa maficha ari pazvikamu zvematani akawanda. Kusiyana nematafura esimbi akaumbwa kana esimbi akagadzirwa, ayo anokombama nekuchinja kwekushisa, anoora nekufamba kwenguva, uye anochengetedza kushushikana kwemukati, granite inoramba isina simba pasi pemamiriro ezvinhu akajairwa eworkshop. Ndosaka mitemo yepasi rose yakaita seASME B89.3.7 neISO 8512-2 ichitsanangura granite seyega chinhu chinogamuchirwa cheGiredhi 00 kusvika Giredhi 1 maplates anoshandiswa mukuenzanisa uye kuongorora kwakanyatsojeka.
Asi chikero chinochinja zvese. Purati huru yegranite pamusoro—ngatitii, 2000 x 4000 mm kana kupfuura—inogona kurema makirogiramu anopfuura 2,000. Pahuremu ihwohwo, kutsigirwa kwayo kunova kwakakosha segiredhi rayo rakati sandara. Dhizaini isina kunaka yekumira (semuenzaniso, kuiswa kwemakumbo asina kuenzana, mafuremu anochinjika, kana kusabatanidzwa zvakanaka) inogona kukonzera kutsauka kunopfuura mabhendi anotenderwa. Semuenzaniso, plate yeGiredhi 0 ine 3000 x 1500 mm inofanira kuchengetedza kutwasuka mukati me ±18 microns pamusoro payo yese zvichienderana neISO 8512-2. Kana stand ichibvumira kunyange kukotama kudiki pakati, spec iyoyo inokanganiswa ipapo ipapo—kwete nekuda kwegranite isina kunaka, asi hunyanzvi husina kunaka.
Apa ndipo pane chikamu che "nekumira"ndiro yepamusoro yegranite chaiyonechigadziko chinoshanduka kubva pachishongedzo kuita chinhu chakakosha. Chigadziko chakavakwa nechinangwa hachisi furemu chete—isystem yekuvaka yakagadzirwa uchishandisa finite element analysis kuti iparadzire mutoro zvakaenzana, kuderedza resonance, uye kupa rutsigiro rwakasimba rwemapoinzi matatu kana akawanda rwakabatana nepfungwa dzechisikigo dzeplate. Zvigadziko zvepamusoro zvine tsoka dzinogadziriswa, dzinoparadzanisa kudedera, dzakasimbiswa cross-bracing, uye ergonomic access kune vanoisa nemidziyo. Zvimwe zvinotobatanidza nzira dzekudzika kuti dziparadze static—yakakosha munzvimbo dzemagetsi kana dzekuchenesa.
PaZHHIMG, takaona nemaziso edu kuti sisitimu chaiyo inochinja sei mhedzisiro. Mumwe mugadziri wemhepo wekuNorth America akatambura nekuyera kusingaenderane kwebore alignment pachigadziko chenacelle. Tafura yavo yegranite yaivepo yaive pafuremu yesimbi yakashandiswazve iyo yaigonya pasi pemutoro. Mushure mekuisa plate yegranite hombe yakabvumidzwa yakaiswa pachigadziko chakagadzirwa nemaoko chine tsoka dzakagadziriswa, shanduko yavo yekubatanidza maoperator yakaderera ne52%, uye kurambwa kwevatengi kwakamira zvachose. Zvishandiso hazvina kuchinja—kungochinja foundation chete.
Zvakakoshawo kuti masisitimu aya anobatanidzwa sei mumabasa ezuva nezuva. Puratifomu yepamusoro yegranite yakagadzirwa zvakanaka ine stand inosimudzira nzvimbo yebasa kusvika pakukwirira kwakanaka (kazhinji 850–900 mm), ichideredza kuneta kwemushandisi panguva refu yekuongorora. Inopa mukana wakajeka wekupinda kubva kumativi ese weCMM arms, laser trackers, kana maturusi emaoko. Uye nekuti stand iyi inoparadzanisa granite kubva mukuzununguka kwepasi—kunowanzo shandiswa padyo nekudzvanya, mitsetse yekutsika, kana mayuniti eHVAC—inochengetedza kusimba kwezviratidzo zvekutsaura zvinonzwisisika kana ma electronic height masters.
Kugadzirisa kunoitawo basa. Kunyange zvazvo granite pachayo isingade kutarisirwa zvakanyanya kunze kwekucheneswa nguva dzose ne isopropyl alcohol, chigadziko chinofanira kuongororwa nguva nenguva kuti chionekwe kuti bhoti rakasimba here, kuti rakatsetseka here, uye kuti chimiro charo chakamira sei. Uye kungofanana neplate, gungano rese rinofanira kuongororwa nguva nenguva. Kuongororwa kwechokwadi kweplate yepamusoro pemasisitimu makuru hakungosanganisiri kungoita mapping yegranite yakati sandara chete, asiwo kuongororwa kwekugadzikana kwesystem yese—kusanganisira kutsauka kwakakonzerwa nekumira pasi pemutoro wakaedzwa.
Pakusarudza plate hombe yegranite, tarisa zvinopfuura saizi nemutengo. Bvunza:
- Chitupa chakazara cheASME B89.3.7 kana ISO 8512-2, kusanganisira mepu yemufananidzo wekutsauka chaiko kwe flatness
- Zvinyorwa zvegranite yakabva (yakagadzirwa zvakanaka, yakasununguka pakushushikana, isina mitswe)
- Mifananidzo yeinjiniya yechigadziko, ichiratidza rutsigiro rwemajiyometri uye magadzirirwo echinhu chacho
- Data rekuongorora kudedera kana richishanda munzvimbo dzinoshanduka
KuZHHIMG, tinoshanda pamwe chete nemaworkshops anobata masisitimu makuru egranite semapuratifomu akabatanidzwa ekuyera zvinhu—kwete zvinhu zvekushandisa. Purati yega yega yegranite ine chigadziko chatinopa inoedzwa yega yega pasi pemutoro, inoongororwa serially kuti inoteverwa here, uye inoperekedzwa nechitupa chekuyera chinoteverwa neNIST. Hatitende kuti "pedyo zvakakwana." Mukuongorora zvinhu zvakakura, hapana mukana wekubvumirana.
Nekuti kana chikamu chako chichidhura manhamba matanhatu uye mutengi wako achida kuti chisave nedambudziko, nzvimbo yako yekunongedzera haifanirwe kunge iri pfuma yako yaunovimba nayo zvikuru—vimbiso yakanyarara yechokwadi munyika ine ma microns anokosha.
Saka zvibvunze kuti: gadziriro yako yazvino iri kutsigira zvinangwa zvako zvekururama here—kana kuti iri kuzvikanganisa chinyararire? KuZHHIMG, tinokubatsira kuvaka chivimbo kubva pasi, nemasisitimu egranite akagadzirwa neinjiniya anopa kururama kwaunogona kuyera, kuvimba, uye kudzivirira.
