Kana mainjiniya achinge ataura cobalt alloy machining zvikamu zve hydraulic pombi, downhole mavharuvhu, kana yakakwirira-kupfeka mawinch shafts, ivo havasi kungosarudza chinhu - ivo vari kubheja pakugadzikana kwedimensional pasi pe300 MPa kumanikidzwa, kuramba galling pa650 ° C, uye microstructural kuenderana kwe500-chikamu. Ndicho chikonzero kutsvaga kweakavimbika cobalt alloy machining zvikamu fekitori kashoma kupera nemitengo yemitengo. Inotanga nekuzvidavirira kwemetallurgical, multi-axis process control, uye zero kushivirira kwekuparadzaniswa kwecarbide muAMS 5387 kana T800-giredhi castings.
Nei cobalt alloys ichida kupfuura yakajairika CNC kugona
Cobalt-based superalloys seStellite 6B, Haynes 188, uye magadzirirwo eT800 anorambira kupfeka uye kuora-asi zvakare anokuya maturusi 3-5 × nekukurumidza kupfuura simbi isina tsvina. Takaona zvitoro zvichitora cobalt nozzle sleeve chete kuti irase 40% yezvikamu zvekutanga-kumhanya nekuda kwechatter-induced surface waviness pamabhori emukati. Chikonzero chikuru? Zvishandiso zvakaomesesa zvigadziriso izvo zvisingatarisire kuwedzera kwemafuta kusawirirana pakati pecobalt (10.4 µm/m·K) uye mahwendefa ealuminium. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., basa rega rega recobalt rinotanga nemepu yemuripo wemafuta-inosimbiswa ne-in-process infrared scanning panguva yekupfuura. Ndiwo mabatiro atinoita ± 0.008 mm kutenderera pa 120-mm-diameter cobalt alloy plugs tichichengeta Ra ≤0.4 µm pakuisa chisimbiso.
Zvina zvisingakwanisi kutaurirana zvechokwadi cobalt alloy machining zvikamu fekitori
Nzvimbo inoda hunyanzvi hwecobalt inofanirwa kuendesa kupfuura kucheka kumhanya. Kubva pamakore gumi nemaviri ekugadzirwa kwepombi-system, izvi zvina zvinogoneka zvinopatsanura varatidziri vakavimbika kubva kune vane tariro vatengesi:
- Material traceability kusvika pakupisa nhamba-kwete zvigayo chete. Kuita kwaCobalt kunotsamira pane chaiyo kabhoni uye tungsten zvirimo; 0.02% kabhoni kutsauka muAMS 5387 inoshandura kuomarara kubva pa42 HRC kuenda pa49 HRC, ichiisa panjodzi yekutyoka brittle mukurodha.
- Yakabatanidzwa kukanda-kune-machining mafambiro-hapana handoffs pakati pekuwana uye muchina shopu. Investment-cast cobalt dzimba dzinodzikira zvisingafungidzike kunze kwekunge machining zvigadziriso zvichireva se-cast datum maficha. Isu tinochina silinda dzimba mukati memaawa makumi manomwe nemaviri ekuzunza, tichishandisa iyo CMM imwechete yakasimbisa kukanda geometry.
- Heat kurapwa kuwiriranisa-Solution annealing inofanira kutangira machining ekupedzisira kuti abvise kushushikana kwasara. Asi kuwedzera-annealing kunopedza chromium carbides, kukanganisa kusagadzikana nekuora. Marogi edu echoto akachinjika-inotaridzirwa nechikamu chimwe nechimwe serial nhamba uye yakabatana kune post-kupisa CMM mishumo.
- GD&T kusimbiswa usati wacheka-kunyanya kushivirira kweprofile pane cobalt nozzles. Iyo 0.05 mm profile callout pachigaro checonical haigoneke neyakajairwa kupera zvigayo. Isu tinotevedzera kutsauswa kwenzira yezvishandiso muVERICUT, tobva tasimbisa nemaOptical contour scanners-kwete maCMM chete.
Uko vatengesi vakajairwa vanokundikana-uye kuti mafekitari anotarisisa nemazvo anopindura sei
Vamwe vagadziri vanobata cobalt sesimbi yakaomeswa: mafidhi akafanana, anotonhorera akafanana, akafanana ekuongorora frequency. Izvo zvinokundikana nekuti cobalt yakaderera yekupisa conductivity inoteya kupisa pamucheto wekucheka. Takaona imwe mutengi cobalt alloy 6 pombi zvikamu zvichitadza kuyedzwa munyu-spray mushure memaawa mazana maviri-kwete kubva kune hurema hwenyama, asi kubva kudiki-kutsemuka kunokonzerwa nemafashama-inotonhorera kudzvanywa (kupfuura 12 bar pane 3-mm-diameter yezviboorero zvemukati). Mhinduro yedu? Minimum quantity lubrication (MQL) ine ester-based oiri, inounzwa pa80 psi kuburikidza ne-spindle nozzles, yakawiriraniswa ne spindle RPM. Kutendeseka kwepamusoro kwakagadziridzwa 70%, uye hupenyu hwekushandisa hwakapetwa kaviri.
Imwe gaka rakajairika: kuyedza kushanda. Iyo cobalt plug haina "kuitwa" kana zviyero zvichipfuura. Inofanirwa kuiswa chisimbiso pa414 bar ichitenderera pa120 rpm ichipokana nezvigaro 420 zvisina tsvina. Isu tinoyedza mijenya yega yega pane yakasarudzika-yakavakirwa hydraulic rigs inodzokorora chaiyo sevhisi torque, tembiricha, uye kutenderera kutenderera-dhata rakadhindwa nekugovaniswa nevatengi.
Kusarudza yako cobalt alloy machining zvikamu fekitori: chiitiko chekutarisa
Usati watumira mifananidzo, bvunza mibvunzo mishanu iyi-uye unoda mhinduro dzakanyorwa:
- Unogona here kupa kupisa-kurapa kutenderera marekodhi ekupedzisira matatu AMS 5387 mijenya akatumirwa?
- Ndeupi hurefu hwako husinga tsigirwe hwe8-mm-diameter cobalt yemukati mabhori-uye ndeipi sisitimu yekushandisa inozviwana?
- Iwe unoita post-machining ultrasonic bvunzo pane dzakakomba zvikamu zvakakora kupfuura 25 mm?
- Iwe unosimbisa sei kuvimbika kwepamusoro pazvigaro zvemachine cobalt valve? (Mhinduro dzinogamuchirwa: kuyera-etch layer kuyerwa, microhardness gradient mepu, kana SEM fractography-kwete chete kuverenga kwaRa.)
- Unogona here kubata chinzvimbo chechokwadi che ± 0.015 mm pamatairi matatu ecoaxial mune imwechete setup ye180-mm-yakareba cobalt centre shaft roller?
Kana mhinduro ipi neipi isina kujeka, inonokerwa, kana mareferensi "maitiro akajairwa," ramba uchitarisa. Cobalt haaregereri fungidziro.
Chekupedzisira chinyorwa: kunyatsojeka haisi dhipatimendi-inotevedzana
Iwo akasimba ecobalt zvikamu zvinobuda kubva pakubatana kwakasimba pakati pezvinhu zvesainzi, machining fizikisi, uye kushanda kwechokwadi. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., zvinoreva kuti vanogadzira chemist vanogadzirisa vanadium zvinoenderana nesvondo rinotevera remachining load, CNC programmers vanogadzirisa mitengo yefeed per real-time tool-wear sensors, uye mainjiniya emhando anoramba chikamu chinodarika chese cheGD&T kana nzvimbo yayo yakasara yekushushikana MP0 inodonha kunze -520. Kutevedzana ikoko-zvinhu → maitiro → kuyerwa → basa-ndosaka mainjiniya achidzokera kune cobalt alloy machining zvikamu fekitori kudyidzana gore negore. Precision haiyerwe mumamicrons chete. Inopimwa muchivimbo.
