Ukugaya nokuphenduka kwe-CNC kuyaguquguquka, kuyabiza futhi kunembile, nokho amathuba ezingxenye zomshini we-CNC anda nakakhulu lapho kucatshangelwa ukuqedwa okwengeziwe.Yiziphi izinketho?Nakuba lokho kuzwakala njengombuzo olula, impendulo iyinkimbinkimbi ngoba kunezici eziningi okufanele zicatshangelwe.
Okokuqala, yini isiphetho salokho?Ingabe ukuthuthukisa ubuhle noma ukusebenza?Uma lokhu kwakamuva, yiziphi izici zokusebenza okudingeka zithuthukiswe?Ukumelana nokugqwala, ukuqina kwendawo, ukumelana nokugqoka noma ukuvikela i-EMI/RFI?Lena ngeminye yemibuzo okufanele iphendulwe ngakho-ke, kucatshangwa ukuthi umklami uyazi ukuthi yiziphi izinjongo, ake sibheke izinketho ezihlukahlukene.
Iqedela izingxenye ze-CNC zensimbi ne-alloy prototype
Eminyakeni engu-40 edlule, ochwepheshe bemishini ye-Prototype Projects baye bacelwa ukuba bakhiqize izingxenye ezivela ohlwini olukhulu lwezinsimbi nama-alloys ukuze kusetshenziswe uhla olubanzi nakakhulu lwezimboni.Izingxenye zomshini we-CNC zikhishwa njalo, zihlanzwe futhi zikhishwe amafutha kodwa, ngemva kwalokho, ukukhetha kokuqedwa okwengeziwe kubanzi kakhulu.
Manje, izinsimbi ezidume kakhulu zamakhasimende ethu yi-aluminium alloy, insimbi engagqwali.
Okusadumile kodwa okucaciswe kancane kakhulu ithusi, ithusi, ithusi le-phosphor, insimbi emnene, insimbi yamathuluzi.Ngezikhathi ezithile, amakhasimende aphinde acele umshini we-CNC kwezinye izinsimbi nama-alloys amaningi.
Izinsimbi nama-alloys kungaqedwa ngezindlela eziningi ezahlukene.Isibonelo, i-aluminium ngokuvamile ingaba i-anodised ecacile, i-hardcoat anodised, noma emnyama noma i-anodised yombala, nakuba i-6082 aluminium alloy yamukela i-anodising kahle kakhulu kunamanye amabanga.Ngokunjalo, i-tooling plate engu-5083 esiyisebenzisayo ingaveza amamaki anamabala.Ukukhetha kuncike ekutheni imfuneko iwukuthuthukisa ubuhle noma ukusebenza (ikakhulukazi ukumelana nokugqwala noma ukumelana nokugqokwa).
Insimbi engagqwali imelana nokugqwala kodwa kwesinye isikhathi amakhasimende acacisa amanye amaqebelengwane.I-Electropolishing, isibonelo, ikhiqiza isiphetho sekhwalithi ephezulu kanye nokukhipha ama-burrs namaphethelo acijile ezingxenyeni eziyinkimbinkimbi.Ngakolunye uhlangothi, uma ubulukhuni bobuso, ukumelana nokugqoka noma ukusebenza kokukhathala kudingeka kuthuthukiswe, kokubili insimbi engu-304 kanye ne-316 ingenziwa i-nitrided noma i-nitrocarburised.
Insimbi emnene izuza ngokukhetha okubanzi kakhulu kokuqedwa.Izinketho zihlanganisa ukudweba okumanzi, umdwebo we-electrophoretic, i-powder coating, i-electroplating, ukubala kwamakhemikhali, ukuqhunyiswa kobuhlalu, i-electropolishing, ukuqina kwekesi, ukunamathela kwe-titanium nitriding (TiN), i-nitriding kanye ne-nitrocarburising.
Ithusi nethusi kuvame ukucaciswa ezingxenyeni ezisebenzayo, ngaphandle kokuqedwa okwengeziwe okudingekayo ngemva komshini.Kodwa-ke, uma kunesidingo, izingxenye zingapholishwa ngesandla, zenziwe nge-electroplated, ziqhunyiswe umhwamuko, zifakwe i-lacquered noma ziphathwe ngekhemikhali emnyama.
Ukuqedwa okuchazwe ngenhla akuzona kuphela ezitholakalayo zensimbi nama-alloys.Sihlala sikujabulele ukuxoxa ngokuqeda namakhasimende futhi sizama ukusiza nomaphi lapho singakwazi khona.
Iqedela izingxenye ze-prototype zepulasitiki ezenziwe ngomshini we-CNC
Njengezingxenye zensimbi ne-alloy, zonke izingxenye zepulasitiki thina umshini we-CNC ziyakhishwa, zihlanzwe futhi zikhishwe amafutha kodwa, ngemva kwalokho, izinketho zokuqeda zivame ukuhluka.
Njengoba iningi lamakhasimende licela izingxenye zepulasitiki ezenziwe ngomshini we-CNC kungaba i-acetal (emnyama noma yemvelo) noma i-acrylic, lezi zinto sizibambele esitokweni senkonzo yethu yokwenza imishini ye-Express CNC.I-Acetal ayikwamukeli kalula ukuqedwa okwengeziwe, ngakho izingxenye ngokuvamile zinikezwa 'njengomshini'.I-Acrylic, njengoba icacile, ivame ukupholishwa ukunikeza ukubukeka okufana nengilazi.Lokhu kungenziwa mathupha ngamamaki angcono alandelanayo e-abrasive, noma ngokupholisha ilangabi.Uma kudingekile, i-acrylic ingapendwa ngopende we-acrylic noma i-vacuum metallised ukuze kuzuzwe indawo ekhanyayo kakhulu.
Ngaphandle kwe-acetal ne-acrylic, thina izingxenye zomshini we-CNC ze-prototype ezivela kuhlu olubanzi lwamapulasitiki obunjiniyela.
Okunye kwalokhu kulula ukukuqeda kunezinye, ngakho-ke wamukelekile njalo ukuxoxa ngezinto zokusebenza futhi uqedele nathi ngaphambi kokucela isaphulelo.Kuye ngepulasitiki, singafaka isihlabathi, izingxenye eziyinhloko futhi sizipende, sizipholise (ngesandla noma ngelangabi), ipuleti elingenagesi noma i-vacuum metallise.Kwamanye amapulasitiki anamandla aphansi, ukulungiswa kwendawo okukhethekile nge-primer noma ukwelashwa kwe-plasma kuyadingeka.
Ukuhlolwa kwe-Dimensional kwezingxenye ze-prototype zomshini we-CNC
Isizathu esisodwa esenza amakhasimende akhethe ukuba nezingxenye ze-prototype ze-CNC eziphrintiwe kunokuthi ziphrintwe i-3D ukunemba okuphezulu.Ukubekezelela kwethu okucashuniwe kwezingxenye zomshini we-CNC kungu-±0.1mm, nakuba ubukhulu buvamise ukubanjelwa ekubekezeleni okuqinile, kuye ngento kanye nejometri.Sihlala sihlola ubukhulu bommeleli ngemva komshini, futhi amakhasimende angaphinda acele izici ezithile ukuthi zihlolwe futhi.
Ngokuvamile izilinganiso zingathathwa ngama-calliper aphathwayo noma ama-micrometer kodwa umshini wethu wokulinganisa wokuhlanganisa (CMM) ulungele ukuhlolwa okuphelele.Lokhu kuthatha isikhathi futhi akutholakali ngesevisi yethu ye-Express CNC kodwa kuyashesha kunokuthumela izingxenye kumuntu wesithathu ukuze zihlolwe i-CMM.Okuhlukile kuphela lapho kudingeka isimiso sokuhlola esiphelele, esihlelwe ngokugcwele se-CMM, noma ingxenye yezingxenye seyenziwe ngomshini futhi kudingeka ukuhlolwa okungamaphesenti angu-100.
Izinketho zomhlangano zezingxenye ze-prototype ezenziwe ngomshini we-CNC
'Ukuhlangana' lapha kusho noma yini kusukela ekufakeni ama-Helicoil ezingxenyeni ze-aluminium alloy noma okufakwe ngochungechunge ezingxenyeni zepulasitiki, ukuya ekufakeni ama-bearings kanye nokusebenzisa amalebula aphrintiwe.Ngokuvamile sicelwa ukuthi sihlanganise izingxenye zomshini we-CNC nezinye izingxenye ze-prototype, kungakhathaliseki ukuthi zenziwe ngomshini we-CNC, i-3D ephrintiwe noma i-vacuum cast.
Eqinisweni, sizokwenza cishe noma yiliphi izinga lokuhlanganisa ama-prototypes asebenzayo noma amamodeli abonakalayo, ahlanganise izingxenye ze-prototype noma ingxenye evamile engekho eshalofini njengoba kudingeka.Enye inketho ukugcwalisa izingxenye zomshini we-CNC nge-polyurethane ngokusakazwa kwe-vacuum.
