Kana yako hydraulic system ikatadza pasi pe350-bar pressure, kana cobalt-alloy pombi nozzle inotsemuka mushure memaawa makumi mana nemanomwe ekuenderera mberi kwekushanda, dambudziko hariwanzo rara mukugadzira. Inogara mu zvakarurama zvikamu machining fekitari iyo yakashandura mifananidzo iyoyo kuva chaiyo chaiyo-apo ma microns anoparadzanisa basa nekukundikana.
Takazvionera pachedu: yeNorth America OEM yakaramba matatu akateedzana majeti eAMS 5387 piston pombi dzimba-kwete nekuti vaitaridzika zvisirizvo, asi nekuti data yeCMM yakaratidza 0.012 mm axial runout pachigaro chekutakura. Ndiyo isingasviki hafu yeukobvu hwebvudzi remunhu. Zvakadaro kutsauka uku kwakakonzera kupera kwechisimbiso nguva isati yakwana uye kudzoka kwemunda. Kugadziriswa kwacho kwanga kusiri kugadzirisazve - kwaive kusimbaradza kudzora kwechibviro: kuteedzera zvinhu zvakawanda, kudzikamisa kwemafuta kusati kwaitwa machining ekupedzisira, uye chaiyo-nguva yekupfeka maturusi muripo pa5-axis mill. Izvo hazvisi zvekugadzira. Ndiyo dimensional discipline.
Nei alloy kuomarara kuchida vertical kubatanidzwa-kwete chete CNC kugona
Cobalt-nickel alloys seT800 uye AMS 5387 haaite se6061 aluminium. Ivo vanoshanda-kuomesa zvine hukasha, vanoita kupisa zvisina kunaka, uye vanoda chaiyo yekucheka paramita-kudzika kune spindle orientation uye inotonhorera yekutumira angle. Chitoro chinongoita CNC machining kazhinji chinoburitsa kunze, chobva chanetsekana nekusarira kwekushushikana mupfungwa panguva yekupedza kucheka. Isu takayera kusvika ku 0.08 mm warpage mujecha-cast CoCr dzimba mushure mekugadzira hutsinye hwega-zvakakwana kurasa chikamu chemadhora mazana maviri nemakumi mana.
Mhinduro haisi kukurumidza michina. Inodzorwa kupindirana pakati pemaitiro:
- Kukandira-machining handoff: Zvirongwa zvekurapa kupisa zvakakiyiwa kunhamba dzejenya-kwete mazuva ekarenda
- Machining-kupedzisa kuenderera mberi: Kutendeseka kwepamusoro kwakachengetedzwa nekunzvenga kubata kwechipiri; hapana kugadzirisa zvakare pakati pekutendeuka, kugaya, nekukuya
- Material-to-dimension cheni: Imwe neimwe mbishi billet inotakura yakazara mill test mishumo (ASTM E112 saizi yezviyo, ASTM E1268 yekusanganisirwa chiyero) yakasungirirwa kune yapera chikamu ID
Ichi ndicho chikonzero "chaizvo zvikamu machining fekitori" zvichireva chimwe chinhu chakasiyana kana kukanda, kugadzira, uye kusimbiswa kwesimbi kunoitika pasi pedenga remba-uye imwe yemhando system.
Iko GD&T inomira kuve theoretical-uye yotanga kuraira mafambiro ebasa
Vatengi vanotitumira madhirowa ane chinzvimbo chekushivirira kwe ± 0.005 mm paØ12 mm bores, zvisinei nekuti chimiro chinogara mu300-mm simbi yekukanda kana 45-mm cobalt plug. Zvimwe zvitoro zvinotora GD&T secheki. Isu tinoitora semepu yekugadzira.
Semuenzaniso: isina-standard winch centre shaft roller ine matatu coaxial bores, imwe neimwe inoda panguva imwe chete chinzvimbo chekutonga chinoenderana nendege yedatum yakagadzirwa 200 mm kure. Standard tsika? Machina iyo datum kutanga, wozotenderedza chikamu uye womisazve kurongeka. Asi thermal drift pakati pesetups inounza kukanganisa kukanganisa. Mhinduro yedu: single-setup 5-axis machining uchishandisa tsika vacuum zvigadziriso zvinobata zvese zviri zviviri nzvimbo yedatum uye inotenderera maficha-yakasimbiswa nelaser tracker kusati kwatanga kucheka.
Izvo hazvisi over-engineering. Iri kubvisa iyo yakakura sosi yekusiyana: kududzira kwevanhu kwekushivirira mirwi.
Traceability iwe unogona kuongorora-kwete kungotora
"Full traceability" inoonekwa pane wese webhusaiti webhusaiti. Chii chinoparadzanisa kuuraya kwakavimbika kubva pakushambadzira kopi?
Mune yedu ISO-inoenderana nzvimbo, traceability kunotanga neyakanyunguduka log-kwete yekutenga odha. Imwe neimwe cobalt alloy batch inotakura:
- Iyo yakasarudzika yevira ID yakabatana nekuongororwa kwemakemikari (ICP-OES yakasimbiswa)
- Grain chimiro mafoto kubva kune longitudinal zvikamu
- Kuoma mepu mhiri kwebillet cross-section (kwete kungoverengera pamusoro)
- Kuwirirana pakati pekupisa kurapwa kutenderera data uye yekupedzisira microhardness munzvimbo dzakakosha
Kana mugadziri wepombi wekuEurope akakumbira kuzara kwezvinhu zvemuviri wevharuvhu weAMS 5387, takaendesa mapeji 17-kusanganisira magirafu enhoroondo yekupisa, matekinoro ekuyedza, uye mishumo yekuongorora yeCMM yeawa. Hapana kuvaka patsva. Hapana fungidziro. Ingori data rakachengetwa, rakadzoserwa mukati me90 maminetsi.
Iyo nhanho yezvinyorwa haiitike pasina yakarongeka yedhijitari workflows-uye pasina kubata chinhu chimwe nechimwe sechinangwa-chakakosha, kunyangwe mune prototype inomhanya.
Chaiyo-yenyika chaiyo haisi yekurova zero - ndeye kutonga kusiyanisa
Kurongeka kwechokwadi hakutsananguriki nechiyero chimwe chete. Ndiko kuenderana kwekutsauka muzvikamu mazana mashanu, mumavhiki matatu ekugadzira, kune vaviri vakasiyana vanoshanda. Isu tinoteedzera CpK tsika - kwete kungopfuura / kukundikana mhedzisiro - kune yega yakakosha dimension pane yega-yepamusoro-kushivirira chikamu. Chinangwa chedu? CpK ≥ 1.67 pane ese maficha apo mashandiro anoita zvinoenderana nekutendeka kwejometri.
Chirango ichocho chinoita kuti titsigire vatengi vanoda zvinopfuura zvikamu-vanoda kufanotaura. Ingave yakabata ± 0.008 mm pachigaro chevharuvhu yekumanikidza inonamira pa420 bar, kana kuchengetedza kushata kwepamusoro Ra ≤ 0.4 µm pahuro yecobalt inogadzirisa abrasive slurry flow, chinangwa chinoramba chakafanana: kubvisa kusava nechokwadi kusati kwasvika kumunda.
Kana application yako ichida kudzokororwa dimensional kugadzikana mune yakakwirira-inoshanda alloys-uye kana "yakavhara zvakakwana" njodzi yekudzikira, zviitiko zvekuchengetedza, kana waranti yezvichemo-ipapo kodzero zvakarurama zvikamu machining fekitari haisiriyo ine michina mitsva. Ndiyo inoyera miganhu yayo, inonyora shanduko yega yega, uye inobata kushivirira sechinhu chinoraramisa-kwete nhamba yakamira pane yakadhindwa.
