Makina anu a hydraulic akalephera pansi pa 350-bar pressure, kapena pampu ya cobalt-alloy pampu imasweka pambuyo pa maola 47 akugwira ntchito mosalekeza, vuto silikhala pamapangidwe. Amakhala mu mwatsatanetsatane mbali Machining fakitale zomwe zinamasulira zojambulazo kukhala zenizeni zenizeni - pamene ma microns amasiyanitsa ntchito ndi kulephera.
Tazionera tokha: a North America OEM anakana katatu motsatizana wa AMS 5387 pisitoni pampu housings-osati chifukwa iwo ankawoneka molakwika, koma chifukwa CMM deta anasonyeza 0.012 mm axial runout pa mpando wonyamula. Ndizo zosakwana theka la makulidwe a tsitsi la munthu. Komabe kupatukako kunapangitsa kuti zisindikizo zisamakhale nthawi yayitali komanso kubweza kwamunda. Kukonzekera sikunali kukonzanso-kunali kulimbitsa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake: Izo sizikupanga. Ndiko kulondola kwa dimensional.
Chifukwa chiyani zovuta za aloyi zimafuna kuphatikiza koyima - osati luso la CNC lokha
Cobalt-nickel alloys ngati T800 ndi AMS 5387 sakhala ngati 6061 aluminium. Amagwira ntchito molimba mtima, samatenthetsa bwino, ndipo amafuna kuti pakhale magawo enaake odulira - mpaka kupendekeka kwa spindle ndi kutulutsa koziziritsa. Sitolo yomwe imangopanga makina a CNC nthawi zambiri imatulutsa kunja, kenako imalimbana ndi kusokonezeka kwapang'onopang'ono kotsalira pakumaliza. Tayeza tsamba lankhondo la 0.08 mm m'nyumba zokhala ndi mchenga za CoCr titapanga makina ovuta okha, okwanira kuti tichotse gawo la $2,400.
Yankho si makina othamanga. Imayendetsedwa molumikizana pakati pa njira:
- Kuponyera-machining handoff: Ndondomeko zochizira kutentha kwatsekeredwa ku manambala oponya—osati masiku a kalendala
- Machining-kumaliza kupitiriza: Umphumphu wapamtunda wotetezedwa popewa kugwiriridwa kwachiwiri; palibe kukonzanso pakati pa kutembenuka, mphero, ndi kugaya
- Unyolo wazinthu-ndi-dimension: Billet iliyonse yaiwisi imakhala ndi malipoti oyesa mphero (kukula kwambewu ya ASTM E112, kuphatikizika kwa ASTM E1268) kumangirizidwa ku ID yomaliza
Ichi ndichifukwa chake "mafakitale opangira makina olondola" amatanthawuza china chake pamene kuponyera, kukonza, ndi kutsimikizira kwazitsulo kumachitika pansi pa denga limodzi-ndi dongosolo limodzi labwino.
Pomwe GD&T imasiya kukhala ongoganiza-ndikuyamba kulamula kayendedwe ka ntchito
Makasitomala amatitumizira zojambula zololera za ± 0.005 mm pa bore za Ø12 mm, mosasamala kanthu kuti mawonekedwewo amakhala muzitsulo za 300-mm kapena pulagi ya cobalt ya 45-mm. Mashopu ena amawona GD&T ngati mndandanda. Timawatenga ngati mapu opanga.
Mwachitsanzo: wodzigudubuza wosakhala wamba wa winch center shaft wokhala ndi ma coaxial bores atatu, chilichonse chimafunikira munthawi imodzi kuwongolera malo okhudzana ndi ndege ya datum yopangidwa ndi 200 mm kutali. Mchitidwe wamba? Konzani datum poyamba, kenako tembenuzani gawolo ndikukhazikitsanso kuyanika. Koma kutentha kwapakati pakati pa makonzedwe kumabweretsa cholakwika chowonjezereka. Yankho lathu: makina okhazikika a 5-axis omwe amagwiritsa ntchito zida za vacuum zomwe zimakhala ndi ma datum komanso mawonekedwe ozungulira - zimatsimikiziridwa ndi laser tracker isanayambe kudula.
Izo sizowonjezera-injiniya. Imachotsa gwero lalikulu la kusiyanasiyana: kutanthauzira kwa anthu kulekerera milu.
Kutsatiridwa komwe mungathe kuwunika-osati kungonena
"Kutsata kwathunthu" kumawonekera patsamba lililonse la ogulitsa. Kodi chimalekanitsa chiyani kuphedwa kodalirika ndi kukopera kotsatsa?
Pamalo athu ogwirizana ndi ISO, kufufuza kumayambira ndi chipika chosungunuka-osati mtengo wogula. Gulu lililonse la cobalt alloy limanyamula:
- ID yapadera ya ng'anjo yolumikizidwa ndi kusanthula kwamankhwala (ICP-OES yotsimikizika)
- Zithunzi zamapangidwe ambewu kuchokera kumagawo aatali
- Kulimba kwa mapu kudutsa billet cross-section (osati kungowerenga pamwamba)
- Kulumikizana pakati pa data yozungulira chithandizo cha kutentha ndi microhardness yomaliza pamadera ovuta
Pamene wopanga mpope wa ku Ulaya anapempha kuti pakhale valavu imodzi ya AMS 5387, tinapereka masamba 17, kuphatikizapo ma graph a mbiriyakale ya kutentha, ma curve oyesera, ndi malipoti oyendera CMM a ola. Palibe kumanganso. Palibe kuyerekeza. Zomwe zangosungidwa, zobwezedwa mkati mwa mphindi 90.
Zolembazo sizichitika popanda kusanjika kwa digito - komanso osatenga gawo lililonse ngati lofunikira kwambiri, ngakhale pamachitidwe oyeserera.
Kulondola kwenikweni sikukhudza kugunda zero-ndikuwongolera kusintha
Kulondola kwenikweni sikumatanthauzidwa ndi muyeso umodzi. Ndiko kusinthasintha kwapatuka m'magawo 500, m'masabata atatu opanga, pamagulu awiri osiyanasiyana. Timatsata mfundo za CpK - osati kungodutsa / kulephera - pamlingo uliwonse wovuta kwambiri pagawo lililonse lololera kwambiri. Cholinga chathu? CpK ≥ 1.67 pazonse zomwe magwiridwe antchito amadalira kukhulupirika kwa geometric.
Chilango chimenecho chimatithandizira kuthandizira makasitomala omwe amafunikira zambiri kuposa magawo - amafunikira zodziwikiratu. Kaya ikugwira ± 0.008 mm pampando wa valve wopanikizika womwe umasindikiza pa bar 420, kapena kusunga roughness pamwamba Ra ≤ 0.4 µm pamphuno ya cobalt yomwe imayang'anira kutuluka kwa slurry, cholingacho chimakhalabe chofanana: kuthetsa kusatsimikizika kusanafike kumunda.
Ngati ntchito yanu ikufuna kukhazikika kobwerezabwereza muzitsulo zogwira ntchito kwambiri - ndipo ngati "kuyandikira kokwanira" kungawononge nthawi, zochitika zachitetezo, kapena zonena za chitsimikizo - ndiye kulondola. mwatsatanetsatane mbali Machining fakitale si amene ali ndi makina atsopano. Ndilo lomwe limayesa malire ake, limalemba zosintha zilizonse, ndipo limawona kulolerana ngati cholepheretsa chamoyo-osati nambala yokhazikika papepala.
