Akatswiri akamanena za makina a nickel alloy machining mapampu a hydraulic, ma valve oyendetsa mafuta, kapena makina othamanga kwambiri, sikuti amangogula zinthu zina - akuteteza kupitiliza kwa magwiridwe antchito pansi pa kutenthedwa kwa kutentha, makina, komanso kuwononga. Chifukwa chake kusankha koyenera fakitale ya makina a nickel alloy Machining zofunika kwambiri kuposa mtengo wokha. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tawona ntchito zambiri zikuyimitsidwa-osati kuchokera ku zolakwika zamapangidwe, koma kuchokera kuzinthu zosagwirizana ndi zinthu, chithandizo cha kutentha chosagwirizana, kapena kutengeka pang'ono pambuyo pokonza makina omaliza.
Nthawi zonse timalandira zojambula zolembedwa kuti "AMS 5387 cobalt-nickel alloy" kuti tipeze makasitomala pongoganiza kuti ogulitsa onse amatenga katundu wa T800-grade mofanana. Iwo samatero. Pochita, gulu limodzi limatha makina okhala ndi zida zodziwikiratu; wina amacheza mosayembekezereka, kusiya ming'alu yaying'ono m'malo ovuta osindikiza. Chifukwa chiyani? Chifukwa kuthekera kwenikweni sikuli papepala - ndi momwe sitolo imatsimikizira chemistry * isanakhale * roughing, momwe imabwezera kupotoza kwamafuta pakumaliza kwa ma axis angapo, komanso ngati CMM yake ikunena kuti ibwereranso ku manambala osungunuka. Ndipamene kuphatikizika koyima kumakhala kosakambitsirana-osati monga kutsatsa malonda, koma monga kuwongolera njira.
Malo athu ku Qingdao amayendetsa makina opangira ndalama komanso makina olondola a CNC pansi pa denga limodzi logwirizana ndi ISO-palibe ma handoffs, palibe mipata ya data. Makasitomala akatumiza chojambula cha pampu chokhala ndi ± 0.01 mm GD&T callouts pa bore concentricity, sitimatumiza kunja ndikukhulupirira kuti katswiri wa makinawo atha kuchipulumutsa. Timayika mawonekedwe apafupi ndi ukonde ndi mitengo yolimba yoyendetsedwa, kenaka timayika makina omwewo omwe amagwiritsidwa ntchito pounika-kuchotsa zolakwika zokonzanso zomwe zimakhazikika pagawo lililonse. Pazinyumba za silinda ya pampu ya piston, izi zikutanthauza kukhala ndi 0.008 mm kutalika kwa 320 mm, ngakhale mutachepetsa kupsinjika pa 950 ° C. Taziyeza—pagawo lililonse.
Zowona zitatu zimasiyanitsa mafakitale odalirika a nickel alloy Machining ndi ena onse:
- Chilango chakuthupi: Timatulutsa ma alloys a AMS 5387 ndi T800 okha kuchokera ku mphero zovomerezeka zokhala ndi zolemba zonse za ladle-to-lot-ndikuyesa bar iliyonse yomwe ikubwera kukula kwambewu, kugawa carbide, ndi intergranular corrosion resistance musanadulidwe. Palibe kuchotserapo.
- Machining nzeru: Ma superalloy opangidwa ndi nickel amafuna kuthamanga kwa spindle, mitengo ya chakudya, ndi njira zoperekera zoziziritsa kukhosi. Timagwiritsa ntchito zowunikira nthawi yeniyeni pamakina athu a 5-axis Mazak—osati kuti tilowe m'malo ogwiritsira ntchito, koma kuyika chizindikiro pamene choyikapo cha carbide chikayamba kutayika m'mphepete *pamapeto* amatsika pamwamba kupitirira Ra 0.4 µm.
- Kutsimikizira kogwira ntchito: Thupi la valve yopanikizika silinachitike "pambuyo poyang'anitsitsa komaliza. Timayesa-kuyesa gawo lililonse ku 1.5 × kukakamizidwa kwa ntchito, kenako timayesa helium kutayikira pa 1 × kuthamanga kwa ntchito. Ikadutsa, timatumiza ndi zipika zonse zoyesa-osati satifiketi yokha.
Ena amafunsa kuti: “Kodi sitolo yachitsulo singakwanitse kuchita zimenezi?” Inde—ngati mbaliyo imagwira ntchito pa kutentha kozungulira, kutsika kwapansi, ndi kusinthasintha kwa ntchito kosachitika kawirikawiri. Koma pamene mphuno ya aloyi ya cobalt iyenera kupirira kukokoloka kwa mpweya wa 650 ° C ndikusunga 0.025 mm orifice kulolerana, kapena pamene winch center shaft roller imazungulira pansi pa 420 MPa kukhudzana ndi kupanikizika kwa maola 10,000+, mphamvu zambiri zimalephera. Tidakhala ndi makasitomala akusintha pakati pa projekiti pambuyo poti wogulitsa wawo woyambirira adaphonya nthawi yothira kutentha ndi mphindi 12 - zomwe zidayambitsa kutopa msanga m'mayesero am'munda. Imeneyo si "nkhani yabwino." Ndi kusiyana kwa ndondomeko.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. sichimathamangitsa volume. Timayang'ana pa zotsatira zobwerezabwereza za zigawo zofunika kwambiri za mishoni: ma valve opanikizika omwe amasindikiza pa bar 700, maziko a pampu omwe amachepetsa kumveka kwa resonance pansi pa 8 Hz, ndi ma shafts omwe sali okhazikika kumene geometry imatanthauzira ntchito-osati mosemphanitsa. Mainjiniya athu amawunikiranso chimango chilichonse cha GD&T, kuwonetsa kulekerera kokakamizidwa, ndikupereka malingaliro opangira njira zina *asanadulire* zitsulo. Sitikunena kuti "inde" kuzinthu zosatheka - timathandiza kufotokozeranso zomwe zingatheke popanda kusokoneza kukhulupirika.
Kuyang'ana m'tsogolo, tikukulitsa njira zosakanizidwa-monga zopangira ndalama zokhala ndi njira zozizilitsira zophatikizika, zomalizidwa ndi mphero yolondola kwambiri komanso kupukuta kwa electrochemical kuti igwire bwino ntchito. Kukula kwa ziphaso kumatsatira kufunidwa: AS9100 pamisonkhano yamagawo amlengalenga, kutsata kwa API 6A kwa mavavu apansi pa nyanja, ndi njira zothina zotsatiridwa ndi zida zanyukiliya. Koma pachimake sichinasinthe: ngati ntchito yanu ikufuna kukhazikika kwa mawonekedwe, kusasinthika kwa microstructure, komanso kudalirika kwa magwiridwe antchito a nickel ndi cobalt alloys - ndiye fakitale ya makina a nickel alloy Machining ayenera kutsimikizira, maere ndi maere, gawo ndi gawo, kuzungulira ndi kuzungulira.
