Uma uzwa 'i-CNC precision machining', izingqondo eziningi zigxuma ziqonde ekubekezeleni kwezinga le-micron kanye nokuqedwa kwangaphandle okungenasici. Yilokho iphimbo lokumaketha, noma kunjalo. Iqiniso esitezi sesitolo ukuxoxisana okuqhubekayo phakathi kokuhle emdwebeni kanye nokuziphatha kwensimbi ngaphansi kwethuluzi lokusika. Ngibone imiklamo eminingi kakhulu iza nokubekezelelana okucaciswe ezindaweni ezintathu zamadesimali lapho okubili bekuzosebenza kahle, ngoba nje 'kubukeka' kunembe kakhudlwana. Lokho kujaha okungadingekile kokuphelela kushayela izindleko ngophahla futhi kwethula isethi yayo yezinkinga. Ukunemba kweqiniso akukhona nje ukushaya inombolo; imayelana nokuphindaphinda, ukuzinza, kanye nokuqonda ukuthi ingxenye empeleni idinga ukwenzani. Umehluko phakathi kwengxenye ekala kahle elebhu elawulwa yisimo sezulu kanye naleyo esebenza kahle iminyaka eminingi emshinini omubi, odlidlizayo.
Isisekelo: Iqala Ngaphambi Komshini
Awukwazi ukukhuluma ngakho CNC ukunemba machining ngaphandle kokuthi uqale ukhulume ngalokho okufaka emshinini. Yilapho amaphrojekthi amaningi, ikakhulukazi ku-prototyping, eya eceleni. Indlela yamathuluzi ehlelwe kahle ayinalutho uma impahla eluhlaza inobunzima obungaguquki noma ukucindezeleka kwangaphakathi. Ngifunde lokhu kabuhlungu kusenesikhathi, ngenza inqwaba yabakaki bensimbi engagqwali. Abayishumi bokuqala baphume bephelele. Ngengxenye yeshumi nanhlanu, saqala ukubona ukukhukhuleka—akukho lutho esilushintshile ohlelweni olungakulungisa. Umlandu? Isitoko esingahluziwe sibe nengcindezi eyinsalela kusukela kunqubo yokuqala yokugingqika kwebha. Njengoba sasikhipha izinto, lokho kucindezeleka kwaphinde kwasakazwa futhi ingxenye yahamba ngokoqobo ku-vise. Isixazululo kwakungewona umshini wokufeketha; ibicacisa into eqeda ingcindezi noma ingeza isinyathelo sokuzinzisa esimangelengele nesishisayo ngaphambi kokuqeda. Yingakho izinkampani ezinobuchwepheshe obujulile bezinto ezibonakalayo, njenge-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), zinomkhawulo ohlukile. Ngeminyaka engama-30 ekulingiseni nasekukhiqizeni imishini, bayaqonda ngokwemvelo ukuthi uhambo lwe- ukunemba ngomshini ingxenye iqala ezingeni le-metallurgical, kungakhathaliseki ukuthi isuka ekubunjweni kwegobolondo elingenalutho noma ibha ye-alloy eyenziwe. Ungathola indlela yabo enemininingwane esizeni sabo kokuthi tsngtaocnc.com.
Lokhu kuholela kokunye ukugada okuvamile: ukulungisa. Ngichithe amahora amaningi ngilungisa okuphakelayo nesivinini, kodwa ngabona ukuthi inzuzo yangempela ibiwukuklama kabusha ukwakheka ngokwezifiso okukhuphule ukuqina kwengxenye ngo-40%. Ukuze uthole indlu ye-aluminium enezindonga ezincane, sake sasebenzisa i-fusible alloy yephuzu eliphansi lokuncibilika ukuze sigcwalise imbobo ngesikhathi somshini. Kunikeze ukwesekwa kwangaphakathi asikwazanga ukuthola enye indlela, okusivumela ukuthi sithathe ukusikeka okunolaka ngaphandle kokuxoxa. Lolo hlobo lobuqili alukho kunoma iyiphi imanuwali ye-CNC ejwayelekile; kuvela ekubambeni ukwehluleka komhlaba wangempela.
Bese kuba nokuphathwa kwe-thermal. Wonke ama-machinist uyazi ukuthi isipholile esokupholisa, kodwa umdlalo onembayo umayelana nokuphatha ukulingana okushisayo. Ukusebenzisa i-spindle enesivinini esikhulu kanzima amahora ayisishiyagalombili kuzofudumeza sonke isakhiwo somshini, mhlawumbe amadigri ambalwa kuphela, kodwa anele ukushintsha iphuzu lakho elinguziro. Ngomsebenzi oqinile ngempela, besivumela umshini usebenze umjikelezo wokufudumala, ukusika umoya imizuzu engu-20 ukuze sivumele yonke into izinze. Kuzwakala kulula, kodwa ukweqa leso sinyathelo kuyindlela elula yokuchitha ingxenye yokuqala yosuku.
I-Precision in CNC Machining iyisistimu
Ngakho-ke unesitoko esihle kanye nokusetha okuqinile. Manje i CNC imishini isikhungo siyathatha. Kodwa nansi into: ukunemba kokuma komshini kuwukuhluka okukodwa nje. Ukuchezuka kwamathuluzi kuyisici esikhulu, esivame ukubukelwa phansi. Usebenzisa isigayo eside, esizacile ukuze ufinyelele ephaketheni elijulile?
