Uma abantu abaningi bezwa 'imishini yokucubungula', babona umugqa ohlanzekile, ozishintshayo ukhala. Iqiniso esitezi sesitolo livame ukuba lukhuni, ukuxoxisana okuqhubekayo phakathi kwesikhathi esifanelekile somjikelezo kanye ne-physics enenkani yensimbi. Umbono oyiphutha omkhulu ukubheka le mishini njengamayunithi angawodwa. Eqinisweni, ukusebenza kwabo kuncike ngokuphelele enqubweni ekhuphuka nomfula—thola ukusakaza okungalungile, futhi ngisho nesigayo esihle kakhulu se-5-axis senza nje izingcucu ezibizayo. Kulapho amashumi eminyaka omsebenzi wokusungula, njengalokho esikwenze e-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kubumba ngokuyisisekelo indlela ocacisa ngayo nokusebenzisa kwakho. ukucubungula imishini.
I-Foundry-Machining Handoff: Lapho Izinkinga Zizalwa Noma Zixazululwa
I-handoff esuka ekulingiseni iye ekwenzeni imishini yisigaba esibalulekile. Awukwazi ukukhuluma ngokusebenza kahle kwe-CNC ngaphandle kokuthi uqale ukhulume ngokungenalutho. Ngokubunjwa kwegobolondo nokufaka utshalomali, sivamise ukubhekana nezingxenye zomumo oseduze nenetha, okulungele ukonga impahla. Kodwa 'near-net' iyi-spectrum. Ukwehluka kwesigamu semilimitha ukujiya kodonga kungase kwamukeleke ekubunjweni, kodwa kusho ukuthi ukusebenza kokuqala kohlelo lwe-CNC—okubheke noma okuyisicefe—akusikhi umoya ngomzuzwana owodwa bese sithatha ukusika okusindayo, okungalindelekile okulandelayo. Le ngxoxo ichitha isiphetho esingaphezulu namathuluzi. Lokhu sikufunde kabuhlungu kusenesikhathi ngenqwaba yezindlu zamaphampu.
Ukukhethwa kwe-alloy kunquma konke okulandelayo. Sisebenzisa ama-alloys amaningi angenasici kanye ne-nickel ukuze kugqwele nokumelana nokushisa. Kuhle enkonzweni, iphupho elibi emshinini. Basebenza kanzima ngokushesha. Uma eyakho ukucubungula imishini ayinakho ukuqina kanye ne-torque ukuze ulondoloze izinga lokuphakelayo elingaguquki, ucwebezela phezulu, uguqule iphasi elandelayo ibe umbulali wamathuluzi. Senza ngendlela efanayo emishinini enezakhiwo ze-box-way ukuze kube nokusikeka okusindayo kulezi zinsiza, sisuka kumhlahlandlela olayini waleyo misebenzi ethile. Akuyona inketho yemfashini, kodwa iyasebenza.
Bese kuba nengcindezi eyinsalela. Ukulingwa kuphola ngokulinganayo. Ihlala, ngezinye izikhathi amasonto, ihlezi ngaphakathi. Uma uyicindezela ku-machining pallet bese usuka ohlangothini olulodwa, ukhulula lokho kucindezeleka. Ingxenye iyanyakaza. Mhlawumbe ama-microns ambalwa kuphela, kodwa esihlalweni sevalvu noma ukunemba kwenqwaba, kuwukwenqatshwa. Manje sakhela imijikelezo yokukhulula ingcindezi—eshisayo noma edlidlizayo—yezingxenye ezibalulekile ngaphambi kokuthi zithinte umbhede we-CNC. Yengeza isikhathi, kodwa isindisa iqoqo lonke kusukela ekwenziweni komshini ukuya kubukhulu obuphelele, obungalungile.
I-CNC Machining: Akukhona nje Ngekhodi
Ingxenye yethu yemishini ye-CNC yilapho imishini yokucubungula ithola khona ukukhanya kwayo. Kodwa ubuchwepheshe bangempela abukho nje ekuhleleni indlela. Isekusebenzeni kwezingxenye zabalingisi. Ibhulokhi engumgunyathi iyabikezelwa; ukulingisa okuyinkimbinkimbi okunezindawo zedatha ezingalingani akukho. Ukudizayina i-fixture ebeka ngaphandle kwezici ze-'as-cast' ngendlela enciphisa ukuhlanekezela ngesikhathi sokubopha kuwubuciko obumnyama. Sinezinhlelo ezibukeka ziyinqaba, ezinemihlathi ethambile yangokwezifiso efana nekhontowunti yokulingisa ngaphambi kokuminyanisa. Iyona kuphela indlela yokuqinisekisa ukuthi ubuso bokuqala obufakwe ngomshini buyidatha ethembekile yawo wonke ama-ops alandelayo.
Isu lokusebenzisa amathuluzi ngomunye umgodi wemali. Ukusebenzisa okufakwa ngaphandle kweshelufu ku-Inconel kuyindlela esheshayo yokushisa imali. Sisebenzisana eduze nabahlinzeki bamathuluzi ukuze sithuthukise amajiyometri angokwezifiso nama-coatings—ngezinye izikhathi okokufaka okubiza kancane okunejiyomethri eyisipesheli ye-chipbreaker kuhlala isikhathi eside ngokuphindwe kathathu kuma-alloys ethu athile. Amandla omshini avulwa yithuluzi. Ngikhumbula ngiphusha i-spindle entsha enesivinini esiphezulu emikhawulweni yayo, ukuze iphrojekthi yehluleke ngoba asikwazanga ukuthola ithuluzi elingakwazi ukuphatha umthwalo oshisayo kulezo zivinini ku-cobalt alloy. Umshini wawunamandla, kodwa ubuchwepheshe obusekelayo babungekho.
I-Coolant ayipholisi nje. Ngomshini ojulile we-cavity iron ductile iron, sidinga isipholile esinengcindezi ephezulu ngokusebenzisa i-spindle ukuze siqhumise ama-chips. Ngokungenasici, sidinga amapholisa asekelwe kuwoyela ukuze sigcobe ukuze sinqande unqenqema olwakhiwe. Ukusebenzisa uketshezi olungalungile kungase kubonakale kukuhle uma kushintshwa, bese kubangele ukwehluleka kwamathuluzi. Sinezinhlelo ezintathu ezihlukene ezimaphakathi. Kuyikhanda elibuhlungu, kodwa akuxoxiswana ngalo mayelana nokuvumelana.
Ukucaciswa Kwezinto Ezibalulekile: UDeveli Ngemininingwane
I-cast iron iyathethelela, ize ingabi njalo. Imishini yensimbi empunga kahle, i-graphite isebenza njengesithambiso. Kodwa nge-high-power ductile iron (njengama-hydraulic components), isakhiwo se-graphite se-nodular siqinile. Udinga amathuluzi abukhali, aqondile. Uma eyakho ukucubungula imishini i-spindle ayilinganisi kuma-RPM aphezulu, uzothola ukudlidliza okuvumelanayo okuholela ekugugekeni kwamathuluzi ngaphambi kwesikhathi kanye nokungaqedi kahle kokuthi yini okufanele kube umsebenzi obhekene nawo olula.
Insimbi engagqwali, ikakhulukazi amamaki aqinisa imvula kwesinye isikhathi esiwatholela ama-specs, iyisilwane esihlukile. Yonke ipharamitha ibalulekile: isivinini, ukondla, ukujula kokusika, indlela yamathuluzi. Isigayo esikhuphukayo uma siqhathanisa nesigayo esivamile singaba umehluko phakathi kwesiphetho sesibuko nendawo edabukile. Sigcina amashidi okugijima anemininingwane engxubevange ngayinye—lawa awaveli encwadini, akhiwe kusukela eminyakeni yamathuluzi aphukile namaqoqo aphumelelayo. Angamadokhumenti ethu angaphakathi abaluleke kakhulu.
Ama-alloys akhethekile, njenge-Hastelloy noma i-Stellite, cishe adinga iseli elizinikele. Ziyalunya futhi ziqinile kangangokuba zingcolisa amasistimu okupholisa kanye namathuluzi ajwayelekile. Sihlela le misebenzi ngamabhulokhi, sidiliza ngokuphelele futhi sihlanze imishini ngemuva kwalokho. Izindleko zibhakwe ku-quote. Ukuzama ukushibhile lapha ngokuyihlanganisa nohlelo lwezingxenye ze-aluminium kuzongcolisa yonke into.
Ukuhlanganisa kanye Nezingqinamba Zomhlaba Wangempela
Ukuthenga isikhungo somshini esisha sezigidi zamadola kuzwakala njengekhambi lazo zonke izinkinga. Akuvamile ukuba kube njalo. Ibhodlela ngokuvamile liyashintsha. Manje usungakwazi ukugaya ingxenye ekusetheni okukodwa emahoreni amathathu esikhundleni samahlanu emishinini emibili. Kuhle. Kodwa manje isiteshi sokususa nokuhlanza sesigcwele amandla ngoba ukhiqiza izingxenye eziqediwe ngokushesha. Noma i-CMM ayikwazi ukuhambisana nomsebenzi wokuhlola. Imishini yokucubungula kumele kubhekwe njengengxenye yohlelo. Izinzuzo zethu ezinkulu kukho konke ukusebenza ngezinye izikhathi zivela ngokungeza ingxenye yewasha yerobhothi noma ukutshala imali kusiqhathanisi esisheshayo esibonakalayo, hhayi ku-VMC entsha ewubukhazikhazi.
Enye ibhodlela efihliwe: ukuhlela nokusetha. Ngomsebenzi wevolumu ephansi, oxubene kakhulu njengoba sivame ukwenza kwa-QSY, umshini ungase uhlelelwe ukusethwa inqobo nje uma uqhubeka. Sitshale imali eningi ezinhlelweni ezingaxhunyiwe ku-inthanethi nasekulingiseni, nasemasistimu e-modular fixture. Umgomo uwukwenza ukuthi uhlelo lomsebenzi olandelayo lufakazelwe futhi lulungiswe ngesikhathi olwamanje lusebenza. Kuyimpi eqhubekayo yokulwa nesikhathi sokuphumula. Isikhathi sokuphotha somshini ukuphela kwemethrikhi ekhokha ngempela izikweletu.
Ukunakekela akuzona izindleko; kuyisidingo. Umshini onezikulufu zebhola ezigugile noma izembozo zendlela ezigcwele ama-chips awusoze wakwazi ukubekezelela, noma ngabe u-opharetha muhle kangakanani. Senza ukugcinwa kokuvikela ngohlelo oluqinile, olusekelwe emahoreni. Amafutha, izihlungi, indlela ama-wiper—umsebenzi oyisicefe, ongathandeki. Kodwa ukuyivumela ukuthi ishelele indlela othola ngayo i-0.01mm tolerance drift eklwebha yonke inqwaba yama-blade omshini wokutshala imali asakazwa ngomshini. Safunda leso sifundo kanye, kabuhlungu.
Ukubheka Emuva, Ukuqhubekela Phambili
Ngemva kweminyaka engamashumi amathathu kule geyimu, kusukela emshinini wokugaya ngesandla kuya ezikhungweni zokugaya zemisebenzi eminingi zakamuva, iqiniso eliwumgogodla lisekhona: umshini muhle kuphela njengenqubo ewuphakelayo kanye nabantu abaqonda umongo wawo. Uhlelo oluphelele lwekhodi ye-G alunamsebenzi uma ukusakaza kunembobo yokushwaqa efihliwe ithuluzi elifika kungazelelwe. I-post-processor ethuthuke kakhulu ayikwazi ukunxephezela into ethile eguqukayo ngaphansi komthwalo.
Ukuziphendukela kwemvelo endaweni yethu, ongalandelela ngayo imishini esitezi sethu kuyo tsngtaocnc.com, kubonisa lokhu kufunda. Asizange nje sithenge imishini esheshayo; sakhe uhlelo oludidiyelwe kakhudlwana. Inqubo yokulingisa yazisa ukulungiselelwa komshini. Izinselelo zomshini zibuyela edizayini yokusakaza yokuphindaphinda okulandelayo. Kuyiluphu.
Ngakho uma ngicabanga ukucubungula imishini manje, angiboni nje insimbi nekhodi. Ngibona okungenalutho okudambisa ingcindezi, umdwebo wesakhiwo ngokwezifiso, umbiko wokugxilisa okupholile, kanye nelogi yokulungisa. Umshini uyindawo okugxilwe kuyo, kodwa umsebenzi wangempela—ubuchwepheshe bangempela—wenzeka esimisweni semvelo esiwuzungezile. Yilokho okuguqula ibhulokhi yensimbi ibe ingxenye ethembekile. Noma yini encane wukuhambisa izinto nje.
