Kana mainjiniya achida micro simbi jekiseni rekugadzira fekitori kugona kwezvikamu zviri pasi pe5 mm ne ± 0.01 mm kushivirira, havawanzo tanga nekutsvaga kweGoogle. Ivo vanotanga neyakakundikana prototype - cobalt alloy nozzle yakatsemuka panguva yekuyedzwa kwe hydraulic pressure, pombi yepombi yepombi yakabuda kunze kwekutenderera mushure mekupisa kupisa, kana winch centre shaft roller yaipfeka zvisina kuenzana mushure memaawa mazana maviri mumamiriro ekunze azere nemunyu. Takaona ese ari matatu - uye akagadzirisa imwe neimwe kwete nekugadzirisa kushivirira, asi nekufungazve kuti kunyatsoita sei diki-chikamu kugadzira mabhiriji mukaha pakati pehupfu simbi uye kuvimbika kwekushanda.
Micro simbi jekiseni kuumba haingori "diki MIM" - inoda kudzora kwesimbi pachiyero chemicron.
Chokwadi diki simbi jekiseni kuumba (μMIM) inosiyana neyakajairwa MIM munzira nhatu dzisingagone kutaurirana: kugovera saizi yehupfu kunofanirwa kugara pasi pe5 μm D.90, kubvisa binder kunoda gradient thermal profiling kudzivirira micro-kutsemuka mumadziro matete (<0.3 mm), uye sintering inofanira kuwana ≥98.5% theoretical density pasina kukora zviyo. Vazhinji vatengesi vanoisa zvikamu se "micro" kana zviri pasi pe10 g - asi chaiwo μMIM zvikamu zvinorema 0.05-2.5 g uye zvinoratidzira senge 0.15 mm-dhayamita yekutonhodza nzira, 0.08 mm kukora kwemadziro, uye GD&T callouts yechokwadi chinzvimbo mukati me0.005 mm.
Ndosaka kusarudzwa kwezvinhu kusiri sarudzo - ndiyo yekutanga sarudzo yeinjiniya. AMS 5387 cobalt alloy inoshanda apo 316 stainless inokundikana: munzvimbo dzakakwirira-velocity slurry, pa450 ° C kushanda temps, pasi pe cyclic kuneta mitoro inodarika 10⁷ cycles. Asi chimiro chayo chakanaka-grained chinoita kuti isaregererwe panguva yekubvisa. Isu tinoshandisa maviri-nhanho solvent/thermal process ine chaiyo-nguva misa-kurasikirwa monitoring - kwete yakatarwa nguva kutenderera - nekuti batch-to-batch musiyano mubinder diffusion rates inokanganisa zvakananga chikamu chegirini kutendeseka.
Vertical kubatanidzwa kunogadzirisa izvo outsourcing breaks
Zvizhinji zvekutadza kwe μMIM zvinodzokera kumashure kune handoffs: iyo MIM supplier ships sintered blanks; iyo machining shopu inonetseka nekushanda pa 3-mm-diameter flanges; iyo inopisa inopisa haigone kutevedzera iyo chaiyo austenitizing rampu inodiwa kune AMS 5387's carbide dispersion. Isu tinomhanya ese matatu matanho pasi peimwe ISO 9001-yakasimbiswa denga muQingdao - uye izvo zvinoshandura zvese.
- CNC machining inoshandisa 5-axis mill ine live tooling uye in-probing probing - yakakosha kana yakatarisana ne0.2 mm-gobvu flange ine ± 0.003 mm kupfava.
- Kurapa kwekupisa kunosanganisira vacuum carburizing yeT800-based components, ine oxygen partial pressure inodzorwa <10⁻⁴ mbar kudzivirira kusvibiswa kwepamusoro pamakona akaoma
- Kupedzisa kwepamusoro kunoshandisa electropolishing ine yazvino density yakamepu kune yemuno geometry - hapana makona asingapofu, hapana madiki-makomba munzira dzekuyerera.
Isu hatingobata kushivirira. Isu tinobata * inoshanda * kushivirira: kushata kwepamusoro Ra ≤ 0.2 μm pakusunga zviso, micro-kuomarara kuenderana kune 0.5 mm muchinjiko-zvikamu, uye kusara kwekushushikana profiles kunosimbiswa kuburikidza neXRD diffraction - kwete kungoomarara Rockwell C macheki.
Dhizaini-yekugadzira-yekugadzira inotanga isati yekutanga CAD faira yachengetwa
Vatengi vanowanzobvunza kuti: "Unogona here kuita izvi?" Isu tinopindura kuti: "Hongu - asi chete kana tikagadzirisa radius pano, kufambisa nzvimbo yegedhi ipapo, uye nekutsanangura mamiriro akasiyana ekunyura." Semuyenzaniso, cobalt alloy plug ine 0.4 mm yemukati shinda yakatadza kasingaperi kudzamara tatama kubva mukati mekuisa post-sinter kuenda kune shinda-kugadzira panguva yegirinhi-nyika machining - ndokuzoisa yakaderera-tembiricha nitriding pachinzvimbo chekuomesera zvakajairwa. Shanduko iyoyo yakacheka chirairo kubva pa37% kusvika 1.8%.
Isu tinosimbisa kudhirowa kwega kwega kwe μMIM kugoneka - kutarisa dhizaini angles (zvishoma 0.5 °), tichinzvenga makona akapinza emukati (R ≥ 0.1 mm), tichiona shanduko yeukobvu hwemadziro (kwete > 3:1 reshiyo), uye kuyerera kwebinder kuyerera kufanotaura mitsetse yeweld mune dzakatetepa-yakavezwa pombi dzimba. Kana GD&T yako ichidaidza chinzvimbo chemubatanidzwa pamadhamu matatu akaparadzana 2 mm zvakaparadzana, isu tichaimisa - uye tokurudzira imwe-yepamusoro datum zano rinounza imwechete inoshanda mhedzisiro ine 40% yakaderera mutengo wekuongorora.
Kuvimbika hakuyerwe mumasitifiketi - inovakwa mune yese mijenya
Traceability haisi mapepa. Iyo laser-etched lot kodhi pachikamu chega chega, cert zvinhu zvakasungwa zvakasungirirwa kune ega sintering run, uye CMM mishumo yakachengetwa kwemakore gumi nemashanu - kwete yekuongorora chete, asi saka kana mishumo yemutengi ichipfeka pamaawa gumi nemaviri ekushanda, tinogona kudhonza iyo chaiyo yekupisa-yekubata rekodhi, binder batch rekodhi, uye optical interfer.ometry zuva rekugadzira rimwe zuva rekugadzira.
Yedu diki simbi jekiseni jekiseni fekitori inoshandira hydraulic OEMs kuGermany vanoda EN 10204 3.1 certs, oirifield makondirakiti muTexas inoda kutevedzera API Q1, uye vagadziri vepombi muSingapore vanoda ASME BPE pamusoro pekupedzisira kusimbiswa. Chinovabatanidza haisi geography - ndiko kuramba kubvuma "zvakanaka zvakakwana" pane zvikamu zvinosimbisa, mita, kana kutenderera pasi pemitoro yakakosha yehupenyu.
Kana yako inotevera diki-chikamu purojekiti inosanganisira cobalt alloys, yakasimba-kushivirira madziro akatetepa, kana inoshanda nzvimbo iyo inofanirwa kurarama abrasive media - tanga nehunhu hwenyama, kwete zvemuchina. Tanga neprocess ownership, not quote speed. Tanga nemudiwa anobata kutsauka kwese kwe 0.02 mm sekuferefeta-chikonzero, kwete kuregererwa kwekushivirira. Ndiyo nzira iyo kunyatsoita kunova kufanotaura.
