Xa umntu esithi 'i-nickel alloy machining parts', umfanekiso wokuqala odla ngokuvela yinto nje enzima kwibhedi ye-CNC. Kodwa kulapho ukwenza lula kakhulu kuqala. Akunjalo nje ngobulukhuni; imalunga nobuntu bezinto eziphantsi koxinzelelo, umdaniso wayo oshushu, kunye nendlela enokutya ngayo ngokuzolileyo isixhobo ukuba awuhoyanga. Ukubaleka iinxalenye ukusuka kwi-Inconel 718 ukuya kwi-Hastelloy C-276, umceli mngeni wokwenyani ayikokwenza nje ukusikwa-kukulawula yonke incoko phakathi komatshini, indlela yesixhobo, kunye nentando enenkani yealloyi.
Uluvo olungelulo lwezondlo nje ezicothayo
Uyakuyiva kakhulu: Kwizinto zenickel alloys, vele wehlise izantya zakho kunye nokutya. Sisiqalo eso, kodwa siyingozi ukuba sisicwangciso sakho kuphela. Ndikhe ndabona iivenkile ziyithatha entliziyweni le nto, ziqhuba yonke into kabuhlungu, ziphela zinomsebenzi owenziwe lukhuni kunye nezixhobo ezisilelayo kubushushu obugqithisileyo kwindawo esikiweyo, hayi ukuqhawuka. I-alloy ayinzima nje; iyacaphuka. Ifuna ukuba nenyongo, ukugalela kwincam yesixhobo. Ke, ukubaleka kancinci ngamanye amaxesha kunokuba kubi kunokuba ndlongondlongo kakhulu. Into ephambili kukuhambelana, ukususwa kwetshiphu elawulwayo. Ukuba ubona ezo chips ziphuma kumfusa obumnyama endaweni yesilivere-yegolide, sele ukwindawo enzima yokusebenza. Luphawu olubonakalayo olugcine imisebenzi emininzi kunayo nayiphi na itafile yeparamitha esele imiselwe.
Uxinzelelo olupholileyo kunye nokuhanjiswa akuxoxiswana apha. Isipholisi sezandyondyo asanelanga. Uyidinga kanye kumda wokusika, ungene kujongano lwesixhobo se-chip. Siye safudukela kwiinkqubo zokupholisa zoxinzelelo oluphezulu ngesixhobo kwiminyaka edlulileyo kwipokotho yethu enzulu yokusila kwimizimba yevalvu, kwaye ibingeyonto ilula-yayikuphela kwendlela yokugcina isixhobo esithembekileyo kwaye sigqibezele esingadingi veki yokusila. Izinto eziphathekayo eziphantsi kwe-thermal conductivity yingcambu yobubi; ubushushu buhlala kanye kwincam. Ukuba awukwazi ukuyikhupha, ulahlekelwa.
Ukukhethwa kwesixhobo kuyeka ukuba malunga ne-brand kwaye kuba malunga nejometri kunye ne-substrate. I-generic carbide end mill yinto enokutyiwa apha. Udinga iifluti ezibukhali, ezikhazimlisiweyo zokunciphisa ukunamathela, kunye nombindi oqinileyo wokujongana noxinzelelo. Senze umgangatho kwiijiyometri ezithile ezinentamo eyomeleziweyo ukwenzela umsebenzi wethu wokufikelela ixesha elide. Kwaye nangona kunjalo, ubomi besixhobo bulinganiswa ngemizuzu, hayi iiyure. Uyayicwangcisa. Uyayibhajetha. Nabani na othembisa ngenye indlela khange enze izinto ezininzi.
Apho Ukusasaza Kudibaniswa Noomatshini: I-Handoff yeDimensional
Lo ngumbono olahlekayo ukuba ivenkile yakho yenza kuphela oomatshini okanye iphosa kuphela. Xa uqala ngokusakha kufutshane ne-net-shape, njengokungundo kweqokobhe okanye utyalo-mali esiluvelisayo Qingdao Qiangsenyuan Technology Co., Ltd.(QSY), iqhinga lomatshini kufuneka livume imbali yokuphosa. Awukwazi ukuphatha i-nickel alloy engenanto efana nebhilethi ekhandiweyo. Ulusu lunokuba nokuguquguquka okuncinci kobulukhuni, kunokubakho intsalela yemathiriyeli yeceramic (nangona inkqubo elungileyo yokufumana iyayinciphisa le nto), kwaye imeko yoxinzelelo lwangaphakathi yahlukile.
Sifunde oku ngeqela elibuhlungu lezindlu zempompo okwethutyana emva. I-castings (Inconel 625) ilinganise kakuhle kwi-CMM emva kokuphosa. Kodwa sakuba sithathe ipasi lokuqala elinzima, yonke loo nto yashukuma. Hayi kakhulu, kodwa ngokwaneleyo ukukrazula inxalenye ebalulekileyo yeflange yobuso. Umba yayingengoomatshini; yayiluxinzelelo olushiyekileyo ekukhupheni okukhupha i-asymmetrically. Ukulungiswa kwakuyinkqubo enamanyathelo amaninzi: i-anneal yokunciphisa uxinzelelo emva kokuphosa (nokuba i-spec ayikhange ibize ngokucacileyo), emva koko isikwe esikhaphukhaphu kakhulu solusu ukuseka isakhelo sedatum esitsha, esizinzileyo phambi kokuba kuqale ukurhabaxa. Yongeza inyathelo, kodwa yasusa inkunkuma. Olu hlobo lokuhlanganiswa kwenkqubo yintoni ivenkile ene-Foundry kunye nevenkile yomatshini phantsi kophahla olunye, njenge QSY, kufuneka ulunge. Ungayibona indlela yethu yokuqhuba oku kudityaniswa komsebenzi kwindawo yethu tsngtaocnc.com.
Ingongoma kukuba, iplani yomatshini ayinakho ukubakho kwivacuum. Umchwephesha kufuneka azi, okanye acinge, ubomi bangaphambili benxalenye. Ngaba yayigalelwe isanti? Utyalo mali? Ngamnye ushiya indawo yokuqala eyahlukileyo kunye neprofayili yoxinzelelo. Utyando olulungileyo lokuqala luhlala lucocekile kwaye lufumane inyani kwimeko ye-as-cast, nokuba oko kuthetha ukuncama isibonelelo sempahla eninzi.
UkuSila (Ngokoqobo) kwePost-Processing
Awufane ufumane isiphelo sokugqibela kanye ukusuka kwindawo yokusila ngezi ngxubevange. Ukusila, i-EDM, okanye i-abrasive flow machining ihlala idlala. Kwaye nanku omnye umgibe: ucinga ukuba ungawucola njengentsimbi yesixhobo. I-nickel alloys idume kakubi ngokulayisha amavili okusila, ukudala iindawo ezichatshazelwe bubushushu, kunye nokudala iintanda ezincinci ukuba undlongondlongo kakhulu. Ndikhumbula ndizama ukubetha i-32 Ra kwindawo yokutywina yecandelo le-Hastelloy X. Ilitye lokusila liyishiye malunga ne-125. Ukutsiba ngaphakathi ngevili elirhabaxa ukuya apho ngokukhawuleza kwatshisa umphezulu. Kwafuneka sibuye umva, sisebenzise ivili elithambileyo, elivuleke ngakumbi elenzelwe i-nickel alloys, kwaye sithathe ukukhanya, ukudlula kwesigulana kunye nokupholisa okwaneleyo. Yayivakala ingasebenzi kakuhle, kodwa yayikuphela kwendlela yokufumana isiphelo esicocekileyo, esingena-crack esiya kudlula uvavanyo lokungena.
I-Deburring sisihogo sayo esikhethekileyo. Ukuqina kwesixhobo kuthetha ukuba ayisuki ngokucocekileyo; iyaqaba. Ukukhutshwa ngesandla ngeefayile okanye amatye kunokusebenza-lukhuni i-burr ngokwayo, iyenze ibe nzima kunemathiriyeli yomzali. Sibe nempumelelo ngeendlela zamandla ashushu kumatshaneli amancinci, antsonkothileyo angaphakathi, kodwa yindleko eyongeziweyo ekufuneka ijongwe kwangoko. Ukuba uyila inxenye ngekona yangaphakathi ebukhali kwi-nickel alloy, wena, ngokunyanisekileyo, uyilo kwingxaki yomatshini.
Xa Okukhethekileyo kuthetha ngaphezu kweKhemistry nje
Ukusebenza kunye iindawo ze-nickel alloy machining kumashishini afana ne-aerospace okanye ukusetyenzwa kweekhemikhali kuthetha ukuba amaphepha abaluleke kakhulu njengenxalenye ebonakalayo. Ukulandeleka kugqibelele. Udinga iicerts zemathiriyeli ekrwada (i-ingot okanye ibha), kufuneka ubhale wonke umjikelo wokunyanga ubushushu, kwaye amaphepha akho enkqubo yomatshini kufuneka achazwe ngokwaneleyo ukuba umntu, ngokwethiyori, aphindaphinde inxalenye ngqo. Oku asikobugqeba; yindlela oqinisekisa ngayo ukuba inxalenye ye-injini yejethi okanye i-reactor yerhasi emuncu ayiyi kusilela. Ukuxubana phakathi kwe-718 kunye ne-725, okanye utshintsho lwesixhobo olungabhalwanga olukhokelela kwi-micro-notch, lunokuba nemiphumo ekude ngaphaya komgangatho wevenkile.
Le meko yolawulo ibumba ishishini liphela. Kungenxa yoko le nto iinkampani zihlala kule ndawo, njenge QSY kunye neminyaka engamashumi amathathu ekujuleni nasematshinini, ukwakha iinkqubo, hayi nje iinxalenye zoomatshini. Ubuchwephesha abukho nje kwikhowudi ye-G yomdwelisi okanye i-Foundryman's ethulula; ikwinkqubo yolawulo lomgangatho edibanisa yonke into. Ufunda ukucinga ngokubhekiselele kuyo yonke inxalenye yobomi ukusuka kwinyibilika ukuya ekuhlolweni kokugqibela, kuba nayiphi na ikhonkco ebuthathaka iphula ikhonkco. Inyanzelisa uqeqesho oluthile ongasoloko ulubona kwiivenkile zemisebenzi ezisebenza ngentsimbi epholileyo imini yonke.
Ekugqibeleni, Imalunga nokuhlonela izinto eziphathekayo
Emva kwayo yonke le minyaka, andiboni i-nickel alloys njengeentshaba, amaqabane anzima. Bafuna intlonipho. Awukwazi ukubaxhaphaza. Kufuneka uphulaphule-isandi sokusikwa, ukujonga kwe-chip, kwidatha evela kwisixhobo sokugqoka izixhobo. Ukuqhuba okuyimpumelelo kuthe cwaka, kunye nesandi esizinzileyo, esimnandi kunye nokuhamba okuqhubekayo kweechips. Iintsilelo zingxola, okanye zivumba lishushu, okanye ziphela ngesandi esiluthuntu.
Eyona nto ithathwayo kuye nabani na ongena kule nto ayisosantya somlingo / itshathi yokutya. Sisimo sengqondo. Qala ngolondolozo, ewe, kodwa zilungiselele ukwenza umfuniselo ngaphakathi kwefestile. Bhala into esebenzayo nengasebenziyo. Qonda ukuba umqhubi wakho weendleko ezinkulu unokuba sisixhobo, hayi ixesha lomatshini. Kwaye ubambisane nababoneleli abayifumanayo-ukusuka kwisiseko esibonelela ngokusasazwa okuzinzileyo kwi-rep yezixhobo ezizisela amabanga kunye neejometri ezisebenza ngokwenene kweli qonga. Yi-niche, kwaye ayixoleli, kodwa ukuyilungisa kuyonelisa ngendlela emangalisayo. Akukho nkohliso xa inxalenye ikwiCMM kwaye ingxelo ye-NDT ibuya icocekile. Nantso ke ubungqina, kanye apho.
