Uma abantu abaningi bezwa 'imishini yokucubungula ukudla', babona ngeso lengqondo imishini yensimbi engenasici ecwebezelayo - izisiki, izixube, ohhavini. Okugejayo, cishe njalo, yizingxenye. Amagiya, amashafti, izindlu, amavalvu, nezinto ezifakwa ngokwezifiso ezenza leyo mishini isebenze. Ukugada kwemboni yakudala: ukugxila kukho konke kuyilapho ubukela phansi ukubaluleka kwezingxenye. Iqiniso liwukuthi, ingxenye eyodwa engaphansi - umzimba wepompo ongakaphonswa kahle noma i-drive shaft engalungile - ingamisa ulayini wokukhiqiza wonke, ibangele ubungozi bokungcoliswa, noma ivele iguge ngemva kwemijikelezo eyizinkulungwane ezimbalwa lapho kufanele ihlale amashumi ezinkulungwane. Owami umbono, owakhiwe eminyakeni eminingi yokuthola nokuxazulula izinkinga, ukuthi izingxenye kulapho kulwelwa khona impi yangempela yobunjiniyela nesayensi yezinto ezibonakalayo. Akuwona ubukhazikhazi, kepha uyikho konke.
Okubalulekile Akulona Nje Ishidi Elicacisiwe
Uthola umdwebo othi 316 steel stainless or cast iron Grade 250. Isiqalo leso, hhayi isiphetho. Ezingxenyeni zemishini yokucubungula ukudla, i-spec iyisisekelo. Ukuhlolwa kwangempela kusendaweni yesicelo. Ingabe i-screw ye-conveyor yesithako esomile? Indlu yephampu yokujikeleza kwe-brine emanzi? Ingxenye yesistimu yomjovo wezinga lokushisa eliphezulu, enomfutho ophezulu? Isimo ngasinye sidinga okungaphezu kwebanga elijwayelekile. I-316L ingase icaciswe, kodwa ezindaweni ezine-acidic, okuqukethwe kwekhabhoni ephansi kanye nokulawulwa okunembile kwe-molybdenum kuba okungaxoxiswana ngakho ukuze kuvinjelwe ukugqwala. Ngike ngabona izingxenye zihluleka hhayi ngenxa yokuthi ziyi-alloy engalungile ephepheni, kodwa ngenxa yokuthi umkhuba we-Foundry's melt wethula ukungahambisani, noma ukwelashwa kokushisa kwakungafanelanga amaphuzu athile okucindezeleka engxenye.

Imisebenzi ehlanganisiwe inciphisa lokhu. Lapho ukulingisa kanye CNC imishini zingaphansi kophahla olulodwa, njengaku-QSY, iluphu yempendulo iqinile. Ochwepheshe bemishini bangakwazi ukwazisa ithimba labasunguli uma bethola njalo ingxenye encane endaweni ethile yesikhunta, noma uma i-alloy ethile iziphatha ngendlela ehlukile ngesikhathi sokusika. Le ndawo-ndawonye ivumela lokho esikubiza ngokuthi idizayini yokwenziwa ngesikhathi sangempela, hhayi nje kumbono. Isibonelo, bangase baphakamise ukungeza i-engeli yokusalungiswa okuncane noma irediyasi encane ekhoneni phakathi nesigaba sokuklama isikhunta esingenzi mehluko wokusebenza engxenyeni kodwa ethuthukisa kakhulu amandla ayo okukhipha kanye nokuqeda komshini.
Ngifunde lokhu kabuhlungu kusenesikhathi, ngithola i-valve eyinkimbinkimbi kubathengisi abahlukene. Ama-castings ayebukeka ephelele. Kodwa ngesikhathi sokwenziwa komshini kokugcina ngumuntu wesithathu, isikhundla sangempela samachweba amaningana sacishwa ngohhafu wemilimitha - okwanele ukuthi singaqondani kahle namapayipi. Umdlalo wokusola uqalile: umsunguli wathi uhlelo lwe-CNC alulungile, umakhi wemishini wathi idatha yokuphonsa ishintshiwe. Umphakeli ohlanganisiwe uqeda lokho kukhomba ngomunwe. Ukuziphendulela kubunye, futhi ulwazi lwenqubo luyanqwabelana.
I-Surface Finish: Lapho Ukuhlanzeka Kuhlala Khona Noma Kufa
Lokhu kungase kube isici esibucayi kakhulu sezingxenye ezithinta ukudla, futhi kuvame ukucwebezela phezu komdwebo onomdwebo olula we-Ra 0.8 μm. Ukuphela kwendawo akukona nje ukushelela; imayelana nokuhlanzeka kanye nokuvimbela ichweba lamagciwane. Ipholishi yesibuko (Ra 0.4 μm noma okungcono) ibalulekile ezindaweni ezithintana ngqo nomkhiqizo, ikakhulukazi izinto ezibonayo noma ezinamathelayo njengenhlama noma ushizi. Kodwa ukuzuza lokho akuyona nje indaba yokusebenzisa isondo elicolisekileyo lokupholisha igrit.
Uhambo oluya kulokho kuphetha kokugcina luqala ngokulingisa. A isikhunta igobolondo noma ukutshala imali inqubo ngokwemvelo ihlinzeka ngokubushelelezi njengokusakazwa kwendawo kunokusakazwa kwesihlabathi okuvamile. Lokhu kusho ukuthi isitokwe esincane esidinga ukususwa ngesikhathi somshini, ukulondoloza ubuqotho bezinto ezibonakalayo kanye nokunciphisa ingozi yokudalula i-porosity engaphansi komhlaba ngesikhathi sokupholisha. Inqubo yokwenza imishini ngokwayo kufanele icophelele. Amasu endlela yamathuluzi, amanani okuphakelayo, kanye nokusetshenziswa kokupholisa konke kuthinta indawo yokugcina. Noma yikuphi ukudabula okuncane, uphawu lokuxoxa, noma isendlalelo sokuphindaphinda siba indawo engaba khona yamagciwane.
Sibe nenkinga ngenqwaba yezinsimbi zomhlahlandlela wokucubungula inyama. Baphumelele ukuhlolwa kuka-Ra nge-profilometer kodwa, ngaphansi kokukhuliswa, babonisa ingxoxo yamathuluzi amancane. Empeleni, amafutha nezicubu kwakuzohlala kule mifantu emincane, okwenza ukukhucululwa kwendle kube yiphupho elibi. Ukulungisa kwakuhilela ukubuyekeza ukunyathela kwethuluzi le-CNC nokusebenzisa ithuluzi elihlukile. Yile mininingwane eyimbudumbudu, cishe ekhathazayo ehlukanisa ingxenye elingana nengxenye esebenza ngokwethembeka ngendlela ephephile ekudleni. Ukujwayelana komphakeli nokuqedwa kwebanga lokudla, njengalezo ezigunyazwe yi-3-A Sanitary Standards noma imihlahlandlela ye-EHEDG, kuyisihlungi okungaxoxiswana ngaso enqubweni yokukhetha.
Iqiniso Lokuhluleka Nokuphindaphinda
Akuzona zonke izingxenye ezisebenza kahle ekuzameni kokuqala, futhi ukwenza sengathi ngenye indlela kuwukungathembeki. Ubuchwepheshe bangempela bomkhiqizi wezingxenye buboniswa endleleni abasingatha ngayo ukwehluleka nokuphindaphinda. Eminyakeni embalwa edlule, sasenza i-prototyping uhlobo olusha lwesibambi se-cutter blade sedayisi yemifino.

Ukuphindaphinda okumbalwa kokuqala, okufakwe ku-martensitic ibala elijwayelekile, eliqhekekile ngesikhathi sokuhlolwa kokukhathala.
Isixazululo asivelanga encwadini. Ivele ekuxazululeni izinkinga ngokubambisana. Iqembu ku QSY iphakamise ukushintshela ku-alloy esekwe ku-cobalt ngenxa yamandla ayo aphakeme okukhathala nokumelana nokugqoka. Kodwa-ke, le alloy idume kanzima ukuyiphonsa kanye nomshini. Okuhlangenwe nakho kwabo nge ama-alloys akhethekile kwangena ukudlala. Balungise amapharamitha wenqubo yokutshala imali - amazinga okushisa angaphambi kokushisa, isivinini sokuthulula - ukuze alawule ukugeleza kwensimbi nokuqiniswa kwale geometry ethile. Ngemva kokusakazwa, bathuthukise ukwelashwa okulungiselelwe okuhambisana nokushisa okunezigaba eziningi ukuze kuzuzwe ibhalansi efanele yobulukhuni nokuqina. I CNC imishini kwase kudingeka ukuthi ivumelane nezinto eziqinile, isebenzisa amathuluzi akhethekile kanye nesivinini. Ukuphindaphinda kwesihlanu kuphumelele. Le nqubo - ukwehluleka, isayensi yezinto ezibonakalayo, ukulungiswa kwenqubo, impumelelo - iwumgogodla ongathandeki wokuthuthukisa okuthembekile izingxenye zemishini yokucubungula ukudla.
Yingakho ukuphila isikhathi eside kulo mkhakha kubalulekile. Inkampani esidlule emijikelezweni eminingi yezomnotho kanye namashifu ezobuchwepheshe, njengebhizinisi elineminyaka engu-30 ubudala, ihlangabezane ngokungenakugwenywa futhi yaxazulula umtapo wolwazi omkhulu wezinkinga ezinjalo. Leyo nkumbulo yesikhungo iyimpahla engabambeki kodwa ebalulekile. Awuthengi nje isikhathi somshini wabo; uthenga ulwazi lwabo oluqoqiwe, oluvame ukuzuzwa kanzima, mayelana nokuthi yini eyenza ingxenye isinde ezweni elijezisayo lokukhiqizwa kokudla.
Ngale Kwengxenye: I-Supply Chain Mindset
Okokugcina, ukucabanga ngezingxenye zodwa kuyiphutha. Zikhona ku-supply chain. Izikhathi zokuhola, ukungaguquguquki kwenqwaba, ukulandeleka, kanye nesitifiketi konke kuyingxenye yomkhiqizo. Kumphathi wezitshalo zokudla, ingxenye ayisizi uma ifika sekwephuzile amasonto amabili ngesikhathi sonyaka ophakeme. Ukungaguquguquki kuyinkosi - iyunithi ye-1000 kufanele yenze ngokufana neyokuqala.
Umkhiqizi oqinile uphatha lokhu ngokuphelele. Iwebhusayithi yabo, njenge tsngtaocnc.com, kufanele kube ingosi yalokhu kwethembeka, hhayi nje ikhathalogi. Ikhuluma ngokuzibophezela ezinqubweni ezithile (ukubunjwa kwegobolondo, ukutshala imali, CNC imishini) kanye nemindeni yezinto ezibonakalayo (kusuka kunsimbi kuya kuma-alloys ane-nickel). Lokhu kugxila kuphakamisa ukujula kunobubanzi. Ngokuhlangenwe nakho kwami, abalingani abangcono kakhulu yilabo abangakwazi ukuchaza ngokucacile lokho abakwenzayo, kodwa kanjani nokuthi kungani benza ngendlela ethile yohlelo lokusebenza olunikeziwe. Bacabanga ngokwezindleko eziphelele zobunikazi bomsebenzisi wokugcina, okufaka ukuqina, izikhawu zokunakekela, kanye nezindleko zokukhucululwa kwendle, hhayi nje inani leyunithi yengxenye.
