Paunonzwa 'advance precision machining', pfungwa zhinji dzinosvetuka dzakananga kune micron-level kushivirira uye inopenya CAD inopa. Ndicho chikamu chazvo, chokwadi, asi chikamu chiri nyore. Iyo chaiyo nyaya inotanga kana iwe uine batch yeInconel 718 castings patafura, iyo inodhinda inodaidzira ± 0.02mm, uye iwe uri kuisa mukupisa kwemhepo, kupfeka kwechishandiso kubva mukumhanya kwekupedzisira, uye kana iyo inotonhorera yekuisa iri panzvimbo. Mukaha uyu uripo pakati peiyo theoretical spec uye chikamu chemuviri-ndipo panonyatsotambwa mutambo uyu. Haisi yekungova nemuchina weakisi mashanu; ndezvekuziva izvo muchina uyu uchanyatsoita na3 PM neChishanu chine hunyoro.
Nheyo: Inotanga neKukanda
Iwe haugone kudhiza machina kuita yekukanda kwakashata. Ndakaona mapurojekiti akawandisa achikanganiswa nekuti mumwe munhu aifunga kuti CNC nhanho inogona kugadzirisa zvemashiripiti epakati kana subsurface porosity kubva kune yekutanga. Iyo machining ndiyo yekupedzisira, tsananguro yakakosha, asi kuvimbika kwechikamu kunozvarwa kare kare. Ichi ndicho chikonzero kubatanidzwa kwekukanda uye machining pasi pedenga remba, senge kuQingdao Qiangsenyuan Technology Co., Ltd. (QSY), haingori nyore kugadzirisa - inzira yakakosha yekudzora mhando. Kana iyo timu imwechete iyo inogadzira chikamu ichi zvakare ichitarisira iyo goko mold kana investimendi yekukanda maitiro, iwe unobvisa iyo yese layer yekunongedza zvigunwe uye kusagadzikana.
Tora basa ravo ne nickel-based alloys. Kugadzira izvi haisi nyaya yekusarudza giredhi rekuisa rakakodzera. Iwe unofanirwa kunzwisisa mafambiro ezviyo kubva pakukandira, kuti mamiriro ekugadzirisa-kurerutsa anozobatana sei nemasimba ako ekusunga, uye kuti nzvimbo dzakasindimara dzakaoma dzinogona kuvanda papi. Kana iyo casting isina kugadzirwa neinotevera advance precision machining mupfungwa, uri kurwa hondo yekukwira kubva kune yekutanga chishandiso kuonana.
Ndinoyeuka chikamu che hydraulic manifold, yakaoma ductile iron piece. Mufananidzo wacho wakanga une hasha. Iyo yekuwana iyo yakaburitsa ma blanks ekutanga haina kubatanidzwa neyemuchina shopu. Zvakaguma nei? Ukobvu hwemadziro husingaenderane kuseri kwezviso zvakakosha zvekuisa chisimbiso, zvichitungamira kuhope panguva yekupedza. Zvimwe zvikamu zvakakweshwa, zvimwe zvakabuda. Dai iyo yekukanda maitiro yakagadziridzwa neyekupedzisira machining coordination senge inotungamira yekupinda-chimwe chinhu chinosanganisa mutengesi senge. QSY anoita sechinyakare-kuti kutambisa uye kugadzirisa zvakare zvingadai zvakadziviswa panobva.
Nzira Yekushandisa Kukurukurirana, Kwete Murairo
CAM software inokupa nzira yekushandisa. Muchina unoedza kuitevera. Maonero asina maturo ndeekuti uku ndiko kupera kwenyaya. Maonero ane ruzivo ndeokuti ndipo panotangira nhaurirano. Chokwadi advance precision machining, kunyanya pane yakaoma geometries kubva pedyo-net-shape castings, iyo yakarongwa nzira inongova yekutanga dhizaini.
Unofanira kuteerera kuchekwa. Ruzha, ruvara rwechip uye chimiro, misiyano mishoma mukuverenga mita inorema - ese imhinduro. Pamuviri wevharuvhu yesimbi isina tsvina, tinogona kuronga kukurumidza kwepamusoro nekudyisa. Asi kana usiri kugadziridza iyo nguva iyo yekupedzisira mill inobata yemukati muchinjiko-inopesana neakachena ekunze madziro, iwe unowana chatter kana kutsauka. Iyo 'yepamberi' chikamu ndeichi chinoshanduka, chinenge chine intuitive, chigadziko chekutonga chinogara pamusoro peG-code. Ndiyo machinist kana programmer achiziva kuti kune iyi batch ye17-4 PH isina tsvina kubva kune yakanyungudika, vanofanirwa kudonhedza chikafu 5% muhomwe.
Apa ndipo panoitwa makore makumi matatu ekumashure anotaurwa neQSY anobatika. Haasi makore makumi matatu chete ekushanda kwemichina; imakore makumi matatu ekuvaka raibhurari yepfungwa yekuti zvinhu kubva kucobalt-based alloys kukanda simbi inoita sei pasi pechishandiso. Iyo raibhurari inozivisa izvo zvidiki-zvigadziriso zvinoparadzanisa chikamu chakanaka kubva kune chakakwana.
Metrology: Kuyera Kuziva (Zvichida)
Heino musungo wakajairika: kunyanya-kuvimba neCMM chirevo. Iwe unowana yekutanga-chinyorwa chekuongorora pepa rine ese egirinhi kukosha uye unofunga kuti uri goridhe. Asi chii chaive chikamu chetembiricha pakuyerwa? Iwo maficha akacheneswa pane zvese zvinotonhorera zvakasara uye micro-burrs? Ko iko kurovera panguva yekuyera kwakanyatso kutevedzera clamping panguva yekugadzira? Kana zvisina kudaro, mushumo wakaisvonaka iwoyo ibasa rengano.
Mukuita basa nemazvo, kuyerwa inyanzvi pachayo. Tinowanzo shandisa musanganiswa wemitoo. Iyo CMM yezere geometric kushivirira, hongu. Asi kune dzakakosha chisimbiso nzvimbo, pamwe yepamusoro profilometer. Kune madhayamita akaboora mukati makadzika, madiki maficha, calibrated air gage kana kunyange chaiyo pini gage set. Chinangwa ndechekubatana-kuita shuwa kuti nyaya dzako dzese dzekuyera dzinobvumirana. Ndakave nemamiriro ezvinhu apo CMM yakati chiboro chiri mukushivirira, asi master plug gage yaisakwana. Mupari wemhosva? Iyo isinganyatso nzwisisike taper kana lobing iyo CMM's point-cloud sampling yakapotsa. Iyo 'yepamberi' pfungwa ndeimwe yekusahadzika kune hutano kune yako wega data.
Kune kambani inobata zvese kubva kune hombe simbi mabhesi kusvika kune yakapfava alloy turbine zvikamu, iyi metrology uzivi hunofanirwa kuve hwakakura uye kuziva zvinhu. Kuyera simbi yakashongedzwa bracket haina kufanana nekuyera yakatetepa-yakavharidzirwa yekudyara-yakakanda cobalt alloy chikamu chinogona kuchinjika pasi pehuremu hwayo paCMM nhanho.
Iyo Special Alloys Arena: Iko Dzidziso Inosangana Nechokushandisa
Chero ani zvake anogona kutarisa masipidhi anokurudzirwa uye mafeed eInconel mubhuku rekushandisa. Kuvatevera kuti vabudise chikamu chinoshanda ndeimwe nyaya. Advance precision machining yeakakosha alloys senge nickel-based kana cobalt-yakavakirwa iwo chidzidzo mukudzorwa kwehasha. Unoda kupisa kwakaringana munzvimbo yekuveura kuti uchengetedze mapurasitiki emidziyo, asi kwete zvakanyanya zvekuti unoshanda-kuomesera kumusoro kuita dhizaini isingapindike inoparadza chimbo chinotevera chekupfuura.
Kusarudzwa kwechishandiso kunova hyper-yakakosha. Kwete chero ceramic kana carbide ichaita. Iyo geometry yekupinza, kupfekedza, chipbreaker dhizaini-zvese zvinoda kugadzirwa. Inotonhodza haisi yekutonhodza chete; ndeyekuzora uye kuburitsa chip pane zvinomanikidza zvinogona kudarika 1000 psi. Kukundikana mune chero chinongedzo chetani iyi zvinoreva chikamu chakaraswa, uye zvinhu izvi hazvina kudhura. Mucheto wekukanganisa ungangoita zero.
Uku ndiko kugona kwepakati kune mutengesi se QSY. Kududza kwavo nezvezvinhu izvi hakusi kutaura; chiratidzo chekuti vakaisa mari mune chaiyo muchina chishandiso kuomarara, yakakwirira-kudzvanya inotonhorera masisitimu, uye zvakanyanya kukosha, ruzivo rwemushandisi kumhanya iyi gauntlet zvinobudirira. Harisi bhizinesi reparutivi; kugona kwakatsaurirwa.
Kubatanidzwa: Iko Kusingaonekwi Kubudirira
Pakupedzisira, ngatitaure nezvekuyerera. Muvengi mukuru wekururama ndiko kusapindirana, uye kusawirirana kunowanzobva pamaoko-offs. Kana kukanda kuchiitwa mune imwe fekitori, kutumirwa kune imwe kune hutsinye machining, zvino kusvika kune chetatu chekupedzisa, iwe unosuma zvinosiyana padanho rega rega. Yakasiyana tembiricha nharaunda, akasiyana clamping uzivi, akasiyana maturusi zviyero.
Kushanda kwakabatanidzwa kunobata shell mold/investment casting uye advance precision machining mukuyerera kwakarongeka kunobvisa izvi zvakasiyana-siyana. Chikamu hachimbofa chakatonhora kusvika kune isingazivikanwe mamiriro pakati pekushanda kukuru. Chikwata chimwe chete chehunyanzvi chinokwanisa kuronga gedhi rekukanda uye nzvimbo dzekusimudza zvichibva pakuti maficha akakosha achagadzirwa kupi, zvichideredza kuwandisa uye kukanganisa. Inobvumira dhizaini yechokwadi yakazara maitiro.
Iyi ndiyo yakavanzika mukana kuseri kweiyo vertically-yakatarisana modhi. Izvo zvishoma nezvemichina yega uye zvimwe nezve tambo isina musono yekudzora kubva kusimbi yakanyungudutswa kusvika pakupera, yakaongororwa chikamu. Iyo chaiyo haina kungogadzirwa mukati; yakabikwa mukuita kwese kubva pazuva rekutanga. Paunenge uchitsvaga zvakaomarara, zvemhando yepamusoro-soro, iyo yekupedzisira-kusvika-kumagumo muridzi weiyo maitiro haisi yeumbozha - kazhinji ndiyo nzira yega yekuvimbisa mhedzisiro inoda kudhindwa.
