Kana vanhu vachinzwa 'zvikamu zvemidziyo yekurapa', vanowanzofunga nezvezvinhu zvisina utachiona, zvinopenya zvakananga kubva pamutsetse. Chokwadi chiri grittier. Iri nezve kukanda kunofanirwa kubata vacuum kutendeseka kwemakumi emakore, kana muchina actuator isingakundikane mushure mezviuru gumi zvekutenderera mune autoclave. Mukaha uripo pakati pekudhirowa uye chikamu chinoshanda ndipo panoitika basa chairo, uye ndiko kunoshandiswa makore.
Nheyo: Inotanga neCast
Iwe haugone kugadzira chikamu chakanaka kubva pakukandira kwakashata. Ndicho chidzidzo chekutanga chakaoma. Kune mabhesi emidziyo yekufungidzira kana radiation therapy gantry zvikamu, kutendeseka kwezvinhu hakugone kutaurirana. Takaona mapurojekiti achimira nekuti yekutanga Investment casting yakanga ine micro-porosity yaingoratidza panguva yekupedzisira machining. Mutengo wemba yakaraswa, inenge yapedzwa simbi isina tsvina mudzidzisi ane hutsinye.
Apa ndipo panowanikwa chiitiko chemuvambi chinoraira kubudirira. Kambani yakadai Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nemakumi matatu emakore emugoko uye kuisa mari, vanonzwisisa kuti kupisa kwesimba kwekudira cobalt-chromium alloy yechishandiso chekuvhiya kwakasiyana zvachose nesimbi isina tsvina. Hazvisi zvekungonyungudusa simbi chete; ndezvekutonga nzira yekusimbisa kudzivirira kushushikana pfungwa dzinova mapoinzi ekukundikana.
Sarudzo pakati peshell mold uye investment casting kune yakapihwa midziyo yezvokurapa chikamu kazhinji inouya pasi kune geometry uye pamusoro pekupedzisira zvinodiwa. Chinhu chakaoma, chakatetepa-chidziro chepombi yemuchina we dialysis? Zvichida mari. A hombe, dhizaini bracket yemubhedha wechipatara? Shell mold inogona kunge ichinyanya hupfumi pasina kupira kuita. Sarudzo haiwanzo kujeka-yakatemwa, uye dzimwe nguva inoda prototyping nzira mbiri.
Precision Machining: Apo Kushivirira Kunoruma shure
CNC machining zvekurapa zvikamu zvinonzwa zvakasiyana. Pane huremu hwepfungwa. Kushivirira kwe ± 0.005mm pachibhorani haisi zano; ndiwo muganhu wechisimbiso chinosangana nemvura yemuviri. Ini ndinorangarira batch yekubatanidza dzimba dzevarwere monitors kwataidzingirira 0.01mm yechokwadi chinzvimbo callout. Muchina uyu waikwanisa, asi kugadzirisa uye kuwedzera kupisa kubva pakucheka 316L simbi isina tsvina kwakatikanda kure. Takazofanira kudzora tembiricha yechitoro zvakanyanya zvakasimba - ruzivo kwete padhirowa.
Maitiro eQSY ku CNC machining yezvikamu zvekurapa zvinowanzobatanidza kutsaurira mitsara yemuchina chaiwo kune mamwe mapoka ezvinyorwa. Kumhanya nickel-based alloys, iyo inoshanda-yakaoma sekupenga, pane imwechete setup sesimbi yakakandwa iresitorendi yehupenyu husingawirirani hwematurusi uye pamusoro pekupedzisira nyaya. Kuzvipatsanura kungaite kunge kusingashande pabepa, asi kunodzivirira kusvibiswa-kwezvinhu zvemukati uye kuchengetedza kugadzikana kwemaitiro. Kugadzikana ikoko ndiko kunovabvumira kurova Ra 0.8μm pamusoro pekupedzisira nguva dzose pamajoini anotakura mutoro, izvo zvakakosha pakudzivirira kutanga kutsemuka.
Iyo post-machining yekusimbisa imwe nhanho. Haisi chirevo cheCMM chete. Kune zvikamu zvemaimplants kana zvenguva refu yekubata michina, isu tinowanzo tsanangura mamwe maitiro ekufambisa kana chaiwo ekuchenesa maprotocol kuti abvise chero akadzamirirwa ma microscopic particles kubva kumachining. Chikamu chinogona kuve chakakwana asi chinopesana nehupenyu kana danho iri rikamhanyiswa.
Iyo Alloy Dilemma: Chishandiso Haisi Ingori Nhamba
Kudoma simbi isina chinhu hakuna zvakunoreva. Ndiyo 304, 316L, kana 17-4PH? Imwe neimwe inoita zvakasiyana panguva yekukanda uye kugadzira, uye imwe neimwe ine yakasiyana corrosion kuramba mbiri munzvimbo yekiriniki. 316L ndiyo bhiza rekushanda nechikonzero chakanaka, asi kune zvikamu zvinoda simba rakakwirira, semabhonzo screw driver kana mamwe maarthroscopic tool shafts, tinosendamira mukunaya-kuomesa mamakisi se17-4PH kana kupinda mukati. special alloys.
Cobalt-based uye nickel-based alloys ari mumubatanidzwa wavo. Iwo anoshandiswa mukupfeka-yakasimba maapplication senge prosthetic ibvi majoini kana mune yakakwirira-tembiricha autoclave racks. Kugadzira kwavo kunozivikanwa kuoma-kumhanya kwakaderera, maturusi chaiwo ejometri, kuyerera kunogara kuchitonhora kubata kupisa. Iyo inobatsira ndeyekupfeka kwakasarudzika uye corrosion resistance. Mutengo ndiwo mutengo wekushandisa uye nguva yakareba yekutenderera. Ndakaona mapurojekiti ekuchinja kubva kune yakajairwa tsvina kuenda kune cobalt alloy kwakapetwa kaviri mutengo wekugadzira, asi yaive nzira yega yekuzadzisa 15-makore sevhisi inodiwa yehupenyu.
Kushanda nemumwe wako ane ruzivo rwakadzama rwekuverenga nekunyora kwakakosha. Haisi yekungova nealloy mustock; ndezvekuziva nzira yekupisa-kuibata-post-machining kuti uwane iyo yaunoda kuomarara pasina kukonzeresa kukanganisa, kana magadzirirwo egating system yekukandira kuti ive nechokwadi cheyunifomu yezviyo chimiro muchimiro chakaoma.
Kukundikana Modes uye Nei
Wese munhu anotaura nezve nzira dzekubudirira, asi kuongorora kukundikana kunodzidzisa zvakanyanya. Taive nekesi ine karuoko keku actuator yerobhoti rekuvhiya. Yakapasa ese ma dimensional cheki asi yakatadza mukuyedza kuneta. Chikonzero chikuru chakadzoserwa kumashure kune musiyano mudiki mune shell mold casting maitiro - kusawirirana kudiki muhukobvu hweganda receramic kwakatungamira kune mutsauko wekutonhora wekutonhora, kugadzira nzvimbo yemicrostructure yakati siyanei. Pasi pemaikorosikopu, zvaioneka. Pasi pemutoro wecyclic, yaive nzvimbo yekutyoka.
Ichi ndicho chikonzero kutonga kwemaitiro kunokosha kupfuura kuongorora kwekupedzisira kwezvikamu zvakakosha. Iwe haugone kuongorora kunaka muchikamu; iwe unofanirwa kuivaka mukati kubva padanho rekutanga rekugadzira mold. Vatengesi vanowana izvi, seQSY nekutarisa kwavo kwenguva refu pakuita kwete kungobuda chete, vanowanzove nevashoma veaya anotyisa, kutadza-kumashure kukundikana. Nhoroondo yavo yemakore makumi matatu inoratidza kuti vakaona-uye vakagadzirisa-aya marudzi ematambudziko kare.
Chimwe chinowanzoitika, kutadza kusinganzwisisike ndeye galvanic corrosion mumagungano. Kushandisa siruu yesimbi isina simbi muimba yearuminiyamu yeruoko rwakareruka rwe scanner inogona kuita seyakanaka, asi pamberi pemamwe maajenti ekuchenesa, inogona kuseta sero rinoparadza. Chikamu hachikundiki pakarepo; inokundikana mushure memwedzi yekushandiswa, kazhinji kunze kwewaranti nguva. Kuongorora kuenderana kwezvinhu padanho rekugadzira idanho risingagone kutaurirana rinowanzo furatirwa.
The Realistic Partnership
Kutenga Zvikamu zvemidziyo yezvokurapa Harisi rekutenga odha. Iko kubatana kwehunyanzvi kunotanga kare pamberi peRFQ. Mhedzisiro yakanakisa inoitika kana mugadziri wemidziyo akabatana neanogadzira panguva yechikamu che prototyping. Ko kona iyi yemukati inogona kutenderedzwa zvishoma kuvandudza hupenyu hwechishandiso pasina kukanganisa basa? Ko uku kukora kwemadziro uku kunogona kuitwa yunifomu kudzivirira kunyura mukukanda here?
Mushandi ane hunyanzvi hwakabatana-kubva pakukanda kuenda CNC machining- inopa maonero akazara. Vanogona kuraira kuti chikamu chakagadzirwa sechigadzirwa chemagetsi chinogona kugadzirwa zvakanyanya sechinhu chimwe-chinokandira chine kushoma kwekupedzisira machining, kuvandudza kutendeseka kwechimiro uye kudzikisa zvinogona kusvibiswa nzvimbo. Iyi mhando yekugadzira-ye-kugadzira yekupinda yakakosha uye inobva mumaoko-pane ruzivo pane yese yekugadzira cheni.
Pakupedzisira, chinangwa kuvimbika mumunda. Chikamu hachisi chinhu chiri pabhiri rezvinhu; chinhu chiri muchigadzirwa icho murapi anovimba nacho. Maonero iwayo anoshandura maitiro aunoita kushivirira kwese, pese pese pekupedzisira callout, uye zvese zvitupa. Inofambisa basa kubva pakugadzirwa kuri nyore kuenda kune enjiniya mupiro. Uye izvo, pakupedzisira, ndizvo zvinopatsanura mutengesi kubva kune yechokwadi kugadzira mudiwa weindasitiri yekurapa.
