Uma uzwa 'izingxenye zomshini ze-CNC ezinembayo', izingqondo eziningi zigxuma ziqonde ekubekezeleni. ±0.005 amayintshi, ±0.001, okuqina kakhulu, akunjalo? Leyo yi-pitch yezinga eliphezulu. Iqiniso, ingxenye ebaluleke kakhulu esitolo nasekuhlanganisweni kokugcina, yenziwe ngendlela engaphezulu kakhulu. Kumayelana nokwazi ukuthi yisiphi isici engxenyeni efuna lokho ±0.001 ngempela, futhi esingaphila ngenjabulo ku-±0.010 ngaphandle kokuhixa. Ukujaha ukunemba okungadingekile kuwumzila osheshayo wokukhipha ibhajethi futhi ugeje umnqamulajuqu. Ngibone imidwebo eminingi kakhulu lapho zonke izici zimakwe njengezibalulekile, okuvame ukusho ukuthi umklami akakaze abambene nengxenye ebonakalayo noma iketango lenqubo elenzayo. Ukunemba kweqiniso kunomongo, akuphelele.
Okubalulekile Ukusikwa Kokuqala
Awukwazi ukukhuluma ngokunemba komshini ngaphandle kokuqala nokungenalutho. Yilapho izitolo eziningi zikhubeka khona. Ithi usebenzisa inqwaba ye-316 stainless ukunemba cnc izingxenye machining okokufaka olwandle. Uma isitokwe esingahluziwe sinokuqina okungahambisani noma ingcindezi yangaphakathi evela emshinini wokugaywa, ulwa nempi ehlulwayo kusukela ekubambeni kokuqala. Ingxenye izonyakaza, izosonteka ngemva kokusikeka kokuqala, futhi akukho sinxephezelo sendlela yamathuluzi enhle esizokusindisa. Yingakho ukutholakala kanye nokucutshungulwa kwangaphambili kwezinto kuyingxenye yomsebenzi.
Lokhu kuhlobanisa nokuthi kungani ezinye izingubo, njenge-Qingdao Qiangsenyuan Technology (QSY), zinomkhawulo lapho zibamba kokubili ukusakaza kanye nokwenza imishini endlini. Ngikhumbula iphrojekthi yendlu yephampu ngensimbi engagqwali eyi-duplex. Ingxenye ivele ku-Foundry yabo njengendlela yokutshala imali eseduze nenetha. Ngenxa yokuthi babelawula ukuqiniswa nokwelashwa kokushisa kokusakazwa, ukucindezeleka okusalayo kwakuncane. Lapho ishaya izigayo zethu ze-CNC, yayizinzile. Besingakhiphi u-60% wezinto ezibonakalayo; besenza ama-bores wokugcina abucayi nama-face seal. Ukunemba kwakhelwe ngaphakathi kusuka kuthela, hhayi nje ukuphoqelelwa emshinini. Leyo iligi ehlukile ekuthengeni isitokwe sebha kanye nokukhipha yonke into.
Ama-alloys afana ne-nickel-based noma asekelwe ku-cobalt? Enye indaba leyo. Basebenza kanzima njengohlanya. Isu lakho lamathuluzi, isivinini sakho nokuphakelayo, ingcindezi yokupholisa kanye nokubeka kwakho—konke akumele kushunwe ukuze kucace nje kuphela, kodwa ukuze kugcinwe isimo esisikwayo. Phusha kancane kakhulu, ucwebeze ubuso bese ubulala okufakiwe. Phusha kakhulu, ukhiqiza ukushisa okushintsha izinto ezibonakalayo emaphethelweni. Kuyi-loop yempendulo lapho inqubo yokwenza imishini ngokwayo ingalulaza ingxenye yobuqotho uma ungafundi ama-chips nomsindo ngendlela efanele.
Lapho Ukubekezela Kuhlala Futhi Kufa
Lena inhliziyo engokoqobo ye ukunemba cnc machining. Akukona mayelana nomgodi owodwa ophelele. Kumayelana nobudlelwano phakathi kwaleyo mbobo, ubuso obukhwezayo bungu-200mm, kanye nembobo enentambo nge-engeli engu-45-degree. Imodeli ye-CAD iphelele. Ukunemba kwevolumu yomshini kungase kuqinisekiswe. Kodwa ukusebenza kwakho, ukukhula okushisayo kwe-spindle ngokuhamba kwamahora angu-8, ngisho nokuguga ekhoneni elilodwa lomhlathi wakho we-vise-lawa ama-gremlin adla isitaki sakho.
Lokhu sikufunde kanzima ebhulokhini ehlukahlukene. Izimbobo ezingamashumi amabili nantathu, zonke zidinga ukunemba kwesikhundla ngaphakathi kuka-0.05mm uma kuqhathaniswa nedatha emaphakathi. Ingxenye yokuqala, eyenziwe ngokusetha okukodwa kuphalethi entsha sha, ihlolwe iphelele ku-CMM. Enhle. Sigijime inqwaba. Ingxenye yenombolo 15 yehlulekile. Inkinga? Kudingeke ukuthi siphenye ingxenye kwezinye izici ezingaphansi. Ukusetha kwesibili kusebenzise isethi ehlukile yezindawo. Ngisho noma kuboniswe kahle, kube khona ukuchezuka kwe-angular okuncane, okunqwabelanayo okuvele kuphela emachwebeni akhiwe ngomshini wesibili. Iphutha belisekuhlelweni kwenqubo yethu, hhayi amandla omshini. Sikuxazulule ngokudizayina kabusha isilungiselelo ukuze sivumele zonke izici ezibalulekile ukuthi zenziwe ekubambeni okukodwa, nakuba kwakusho ukusebenzisa ukusetha kwetshe lethuna elibiza kakhulu, langokwezifiso. Izindleko zaleyo midlalo bezingaphansi kwe-scrap nokusebenza kabusha.
I-Tooling Feel You Can't Program
Isoftware ye-CAM iba ngobuhlakani njalo ngonyaka. Kodwa alinawo umzwelo wemvelo. Kukhona isikhashana ekwenzeni imbobo yensimbi ejulile, enobubanzi obuncane—ungezwa lapho i-drill iqala ukulayisha, ngaphambi kokuthi i-torque monitor iqhume. Yilapho uphula umjikelezo, uhlehlisa, usula ama-chips, futhi mhlawumbe ulungise ukujula kwepekhi. Iwukuphazamiseka kohlelo oluhle kakhulu, kodwa ilondoloza ithuluzi eliphukile eligqitshwe engxenyeni eseqediwe, ebizayo.
Lo muzwa udlulela kuma-surface finishes ezindaweni ezivaliwe. Uhlelo luthi sebenzisa i-ball-nose end mill ethize ene-stepover ukuze uqede u-Ra 0.8. Kodwa uma ingxenye inokugoba okuncane noma ithuluzi lino-0.01mm wokuphuma, uthola iphethini ye-cusp ezwakala ilukhuni ngisho noma imitha ye-Ra ithi kulungile. Kwesinye isikhathi, ukulungisa kuba iphasi ye-manual, ehamba kancane enephuzu elilodwa ngethuluzi elisha, elizinikele. Ayisebenzi kahle ephepheni, kepha yikho okuletha ingxenye evala kahle ngaphandle kokuhlakazwa kwe-gasket. Ngeke ukuthole lokho kunqubo yokusebenza ejwayelekile; kusesihlahla sesinqumo sikachwepheshe.
Ukuhlola: Isango Lokugcina, Elingaxoxiswana
Ukunemba akukhona lokho umshini othi wakwenza; yilokho okuqinisekiswa idivayisi yokulinganisa. Lokhu kubonakala kusobala, kodwa igebe phakathi kwalaba ababili lingaba umbulali webhizinisi. Ngikholelwa ngokuqinile ukuthi indlela yokuhlola kufanele ichazwe ngaphambi kokusikwa kwe-chip yokuqala. Uma i-groove yangaphakathi ebalulekile kunzima ukufinyelela kuyo nge-CMM probe, udinga igeji esebenzayo noma uhlelo lokuhlola lwezigaba ezihlukene kusukela ekuqaleni.
Sasebenza naye QSY ochungechungeni lwemizimba yama-valve lapho ukucaba kwe-flange kanye ne-perpendicularity ye-stem bore kwakubucayi. Indlela yabo yayiyi-pragmatic. Abazange nje babe yi-CMM yonke ingxenye. Basebenzise ipuleti elingaphezulu legwadle kanye nenkomba yokudayela ukuze bahlole ngokushesha ukucaba kwe-flange phansi kwesitolo ngo-100% wezingxenye—ezisheshayo, ezethembekile, futhi eziboshelwe ngokuqondile emsebenzini. I-CMM yasetshenziswa ekucwaningweni kwe-athikili yokuqala kanye nezikhathi ezithile. Le nhlanganisela ye-high-tech kanye ne-metrology yakudala iwuphawu lwesitolo esiqonda ukuthi ukuhlola kuyingxenye yokugeleza kokukhiqiza, hhayi isithiyo esihlukile, sokuphatha. Umlando wabo omude ekulingiseni kanye izingxenye zemishini ye-cnc ikhombisa lapha-kungenzeka bafake ngaphakathi ukuthi ukubekezelelana kubaluleke ngani ekusebenzeni ezizukulwaneni zezingxenye.
Izindleko Zangempela Zokunemba
Ngakho, ukuzungeza emuva. Lapho uhlola ukunemba cnc izingxenye machining, awugcini nje ngokuthenga i-geometry. Uthenga ukuqonda komkhiqizi walo lonke lolu chungechunge: ukuziphatha okubalulekile, ukuhlela inqubo, ukuphathwa kwamathuluzi, nokuhlola okungokoqobo. Ikhotheshini eshibhe kakhulu ngengxenye ngayinye ngokuvamile ivela esitolo esinganaki izindleko zokuzinza, kokubili kokubalulekile kanye nasezinqubweni zabo.
Inkampani efana I-Qingdao Qiangsenyuan Technology Co., Ltd., neminyaka engamashumi amathathu ekulingeni nasekukhiqizeni imishini, ihlanganisa lo mbono ohlanganisiwe. Amandla abo ngama-alloys akhethekile akuwona nje umugqa kuwebhusayithi; iwulwazi oluzuzwe kanzima lwendlela yokuguqula ukulingisa okunzima kube indawo engenalutho ezinzile, eshintshwayo. Leso sisekelo senza owokugcina ukunemba imishini isinyathelo esibikezelwayo nesinokwethenjelwa. Umgomo awulokothi ube yingxenye ekala kahle. Iyingxenye elingana, esebenza, futhi ehlalayo, ngaphandle kwedrama, kunoma iyiphi inhlangano ehloselwe yona. Lokho ukunemba okunokubaluleka.
Ekugcineni, umshini onembe kakhulu yilowo osetshenziswa ngumuntu owaziyo ukuthi yini angayinaki eshidini lokubonisa nokuthi yini okufanele ayilwele phansi esitolo. Okunye ukususwa kwensimbi nje.
