I-CNC yokugaya kunye nokujika iyaguquguquka, iyabiza kwaye ichanekile, kodwa amathuba omatshini we-CNC ayanda nangakumbi xa kuqwalaselwa ukugqitywa okongeziweyo.Zeziphi iindlela onokukhetha kuzo?Nangona oko kuvakala njengombuzo olula, impendulo intsonkothile kuba zininzi izinto ekufuneka ziqwalaselwe.
Okokuqala, yintoni ukugqiba?Ngaba kukuphucula ubuhle okanye ukusebenza?Ukuba le yokugqibela, yeyiphi imiba yokusebenza ekufuneka iphuculwe?Ukunganyangeki kokutya, ukuqina komphezulu, ukumelana nokunxiba okanye ukukhuselwa kwe-EMI/RFI?Le yeminye yemibuzo ekufuneka iphendulwe ke, sicinga ukuba umyili uyazazi iinjongo, makhe sijonge kwiinketho ezahlukeneyo.
Ukugqitywa kwe-CNC yomatshini wentsimbi kunye neenxalenye zeprototype yealloyi
Kule minyaka ingama-40 idlulileyo, oomatshini bePrototype Projects baceliwe ukuba bavelise iinxalenye kuluhlu olukhulu lwesinyithi kunye nealloys ukuze zisetyenziswe kuluhlu olubanzi ngakumbi lwamashishini.Amalungu omatshini we-CNC ahlanjululwa rhoqo, acocwe kwaye ahlanjululwe kodwa, emva koko, ukhetho lokugqitywa okongezelelweyo lubanzi kakhulu.
Ngoku, iintsimbi ezidumileyo zabathengi bethu yi-aluminium alloy, intsimbi engatyiwa.
Isaziwa kodwa icaciswe kaninzi lubhedu, ubhedu, ubhedu lwephosphor, intsimbi ethambileyo, intsimbi yesixhobo.Ngamaxesha ngamaxesha, abathengi baphinda bacele ukwenziwa komatshini we-CNC kwezinye iintsimbi ezininzi kunye nealloys.
Iintsimbi kunye ne-alloys zinokugqitywa ngeendlela ezininzi ezahlukeneyo.Umzekelo, i-aluminiyam ngokubanzi inokucaca i-anodised, i-hardcoat anodised, okanye imnyama okanye i-anodised enombala, nangona i-6082 i-aluminium alloy iyamkela i-anodising engaphantsi kakuhle kunamanye amabanga.Ngokunjalo, i-5083 tooling plate esiyisebenzisayo inokuvelisa amanqaku anamachokoza.Ukhetho luxhomekeke ekubeni imfuno kukuphucula i-aesthetics okanye ukusebenza (ngokukodwa ukuxhathisa ukubola okanye ukuxhathisa ukunxiba).
Intsimbi estainless iyakwazi ukumelana nomhlwa kodwa ngamanye amaxesha abathengi bachaza izinto ezongeziweyo.Umzekelo, i-electropolishing, ivelisa umgangatho ophezulu kunye nokususa ii-burrs kunye neencam ezibukhali kwiindawo ezintsonkothileyo.Kwelinye icala, ukuba ukuqina komphezulu, ukumelana nokunxiba okanye ukusebenza kokudinwa kufuneka kuphuculwe, zombini i-304 kunye ne-316 insimbi engenasici inokuba yi-nitrided okanye i-nitrocarburised.
Iinzuzo zentsimbi ethambileyo ukusuka mhlawumbi kolona khetho lubanzi lokugqitywa.Ukhetho lubandakanya ukupeyinta okumanzi, ukupeyinta kwe-electrophoretic, ukugquma umgubo, ukufakwa kwe-electroplating, ukwenza imichiza emnyama, ukuqhushumba kweentsimbi, ukupholisa i-electropolishing, ukuqina kwetyala, ukugquma kwe-titanium nitriding (TiN), i-nitriding kunye ne-nitrocarburising.
Ubhedu kunye nobhedu zidla ngokuchazwa kwiindawo ezisebenzayo, ngaphandle kokugqiba okufunekayo emva komatshini.Ukuba kuyimfuneko, nangona kunjalo, iindawo zinokuthi ziphuculwe ngesandla, i-electropolished, i-electroplated, i-vapor blasted, i-lacquered okanye iphathwe nge-chemical blacking.
Ukugqitywa okuchazwe ngasentla akukuphela kwento ekhoyo yesinyithi kunye ne-alloys.Sihlala sonwabile ukuxoxa ngesiphelo kunye nabathengi kwaye sizama ukunceda naphi na apho sinakho.
Ukugqibezela iinxalenye zeprototype zeplastiki zeCNC
Njengoko kunye nentsimbi kunye neengxenye ze-alloy, zonke iinxalenye zeplastiki thina umatshini we-CNC zihlanjululwe, zicociwe kwaye zihlanjululwe kodwa, emva koko, ukhetho lokugqiba luvame ukuhluka.
Njengoko uninzi lwabathengi bacela i-CNC yomatshini weprototype yenxalenye yeplastiki nokuba yi-acetal (emnyama okanye yendalo) okanye i-acrylic, sizibambele esitokhweni senkonzo yethu yomatshini ye-Express CNC.I-Acetal ayikwamkeli lula ukugqitywa okongeziweyo, ngoko ke iindawo zidla ngokubonelelwa 'njengomatshini'.I-Acrylic, ecacileyo, idla ngokugudiswa ukunika imbonakalo yeglasi.Oku kunokwenziwa ngesandla ngamabakala acolekileyo ngokulandelelanayo okurhawuzelisa, okanye ngokukhazimliswa kwedangatye.Ukuba kuyimfuneko, i-acrylic inokupeyintwa ngepeyinti ye-acrylic okanye i-vacuum metallised ukufikelela kwindawo ebonakalisa kakhulu.
Ngaphaya kwe-acetal kunye ne-acrylic, thina CNC iprototype yomatshini wecandelo ukusuka kuluhlu olubanzi lweeplastiki zobunjineli.
Ezinye zezi kulula ukuzigqiba kunezinye, ngoko wamkelekile ukuba uxoxe ngemathiriyeli kwaye ugqibezele nathi phambi kokuba ucele ikowuti.Ngokuxhomekeke kwiplastiki, singenza isanti, iindawo eziphambili kunye nokupeyinta, ukupolisha (ngesandla okanye ngedangatye), ipleyiti engenambane okanye i-vacuum metallise.Kwezinye iiplastiki ezinamandla aphantsi komhlaba, ukulungiswa kwengcali yendawo kunye ne-primer okanye unyango lwe-plasma luyimfuneko.
Ukuhlolwa komda kweendawo zeprototype zomatshini we-CNC
Esinye sezizathu zokuba kutheni abathengi bakhethe ukuba neenxalenye ze-CNC ezenziwe ngoomatshini endaweni ye-3D eprintiweyo kukuchaneka okuphezulu.Ukunyamezela kwethu okucatshulweyo kumacandelo omatshini e-CNC yi-±0.1mm, nangona imilinganiselo iqhele ukubanjelwa kukunyamezelana okungqongqo, ngokuxhomekeke kwimathiriyeli kunye nejometri.Sihlala sijonga imilinganiselo yommeli emva komatshini, kwaye abathengi banokucela iimpawu ezithile ukuba zihlolwe ngokunjalo.
Rhoqo imilinganiselo inokuthatyathwa ngeefowuni eziphathwa ngesandla okanye ii-micrometers kodwa umatshini wethu wokulinganisa wolungelelwaniso (CMM) ulungele uhlolo olucokisekileyo.Oku kuthatha ixesha kwaye akufumaneki ngenkonzo yethu ye-Express CNC kodwa ikhawuleza kunokuthumela iinxalenye kumntu wesithathu ukuze kuhlolwe iCMM.Ekuphela kwezinto ezinxaxhileyo kuxa inkqubo yokuhlola i-CMM ebanzi, ecwangciswe ngokupheleleyo ifuneka, okanye ibhetshi yamacandelo yenziwe ngoomatshini kwaye kufuneka i-100 leepesenti ihlolwe.
Iinketho zeNdibano zeendawo zeprototype zomatshini we-CNC
'Ukudityaniswa' apha kuthetha nantoni na ukusuka ekufakeni ii-Helicoil kwiindawo ze-aluminiyam okanye izinto ezifakwe ngemisonto kwiindawo zeplastiki, ukuya kuthi ga ekufakeni iibheringi kunye nokusebenzisa iilebhile eziprintiweyo.Rhoqo siye sicelwe ukuba sidibanise iinxalenye zoomatshini be-CNC kunye nezinye iinxalenye zeprototype, nokuba zenziwe ngoomatshini be-CNC, i-3D eprintiweyo okanye i-vacuum cast.
Enyanisweni, siya kwenza phantse naliphi na inqanaba leendibano zeprototypes ezisebenzayo okanye iimodeli ezibonakalayo, ezibandakanya iinxalenye zeprototype okanye i-standard off-the-shelf componentry njengoko kuyimfuneko.Enye inketho kukuguqula ngaphezulu kweendawo zoomatshini ze-CNC nge-polyurethane nge-vacuum casting.
