CNC milling yenye iinkonzo CNC ezikhoyo

CNC milling yenye iinkonzo CNC ezikhoyo. Le yindlela yokuvelisa i-subtractive ngenxa yokuba uya kusebenzisa le nkqubo ukuphuhlisa iimveliso ngoncedo lwemishini ekhethekileyo, eya kususa iinxalenye kwibhloko yezinto. Ngokuqinisekileyo, umatshini uya kusebenzisa isixhobo esikhethekileyo sokunqumla inxalenye yezinto. Ngoko ke, oku kwahluke ngokupheleleyo kwinkonzo yoshicilelo ye-3D, kuba kule nkqubo, uya kusebenzisa umshicileli we-3D ukwenza izinto. I-CNC milling ngoko yahlukile, kodwa isetyenziswa kancinci. Ngezantsi uya kufumana iinyani ezintathu ezibalulekileyo ekufuneka uzazi.
Ayizizo zonke iimatshini ze-CNC ezicutshungulwayo, ezinokuthi zibhideke. Nangona kunjalo, i-CNC ibhekisa kwitekhnoloji, hayi inkqubo ethile. Le teknoloji ibizwa ngokuba yikhompyuter yolawulo lwamanani, okanye ke ngoko ishunqulelwe njenge-CNC. Ingasetyenziswa koomatshini bokungqusha kunye neeleyile ukuze kusetyenziswe iindlela zokwenziwa kwemveli. Nangona kunjalo, i-CNC ingasetyenziswa kunye neeprinta ze-3D, ii-jet cutters zamanzi, oomatshini bokukhupha umbane (ECM) kunye nabanye oomatshini abaninzi. Ukuba umntu usebenzisa igama elithi "CNC Machining“, kububulumko ukubabuza kanye ukuba kuthetha ukuthini. Basenokuthethaoomatshini bokusila be-CNC, kodwa oku akusoloko kunjalo.
Ke ayisiyiyo yonke i-CNC yokugaya, kodwa yonke i-milling iyasebenza ngokwenene. Yintoni lento? Umatshini yinkqubo yokuthabatha oomatshini. Oku kunjalo ngenxa yokuba isusa ngokwasemzimbeni impahla emsebenzini. Eyona ndlela ixhaphakileyo ngoncedo lweeleyile kunye noomatshini bokugaya. Ezi zahluke kancinane. Isingqusho sisebenzisa isixhobo esijikelezayo ukusika okanye ukugrumba izinto. Xa i-workpiece igxininiswe kwindawo, isixhobo siya kujikeleza ngokukhawuleza. Ilathe iya kuzitshintsha ezi. Ke ngoko, i-workpiece iya kujikeleza ngokukhawuleza, kwaye isixhobo siya kudlula kancinci kwi-workpiece ukususa izinto.
Zininzi iintlobo zokungqusha, kodwa ezona zixhaphakileyo zimbini zezezingqusho ezithe nkqo kunye nezingqusho ezixwesileyo. Oku kubhekisa kwi-axis yentshukumo eqala kwisixhobo. Le mizi-mveliso mibini isenokubonakala ifana kakhulu, kodwa ukuba uyijonga ngononophelo, unokubona ngokulula umahluko othile. Uhlobo ngalunye lomatshini wokusila lunezinto zalo eziluncedo kunye nezingeloncedo. Ngokubanzi, izingqusho ezithe nkqo azibizi nje kuphela, kodwa zincinci kwaye kulula ukuzisebenzisa kunezingqusho ezithe tyaba.
Umatshini weCNC oqhelekileyo unokwenziwa ngeendlela ezahlukeneyo. Ezona ziqhelekileyo zimbiniCNC Machiningiinkonzo yi CNC milling kunyeUkujika kwe-CNCg iinkonzo. Ezi ziinkqubo zemihla ngemihla zocweyo lomatshini. Zombini iindlela zisebenzisa izixhobo zokusika ukuze zisuse izinto ezivela kwizinto zokusebenza eziqinileyo. Oku kuya kusetyenziselwa ukwenza iimveliso ze-3D, ezinokuthi zenziwe ngoshicilelo lwe-3D lwe-intanethi. Zombini i-CNC yokugaya kunyeUkujika kwe-CNCzithathwa njengeendlela zokuvelisa ezithathayo. Oku kungenxa yokuba zonke zisusa izinto eziphathekayo. Kukho umahluko ophambili phakathi kwezi nkqubo zimbini, onokuzifunda ngezantsi.
Igama elithi ukujika libhekisa kwinxalenye kuba ijikeleza i-axis esembindini. Isixhobo sokusika ke ngoko siya kuhlala simile kwaye asiyi kujikeleza. Nangona kunjalo, iya kuhamba. Ingena kwaye iphume kwi-workpiece ukwenza i-incision. Ukuguqula kusetyenziselwa ukudala iisilinda kunye ne-derivatives yeesilinda. Imizekelo yale nxalenye i-shafts kunye neentsimbi, kodwa kunye namalulwane e-baseball anokuveliswa ngoncedo lwe-CNC yokujika. I-workpiece iya kulungiswa kwi-spindle ejikelezayo nge-chuck. Ngexesha elifanayo, isiseko sibambe isixhobo sokusika ukuze singene okanye siphume nge-radially ecaleni kwe-axis. Umyinge wokujikeleza we-workpiece uya kuchaphazela ukutya kunye nesantya, njengobunzulu be-radial yokusikwa kunye nesantya apho isixhobo sihamba nge-axis.
I-CNC yokugaya yahluke kakhulu kwi-CNC yokujika. Ngethuba lomsebenzi wokugaya, isixhobo siya kujikeleza. I-workpiece iya kulungiswa kwi-worktable, ngoko ayiyi kuhamba konke. Isixhobo sinokuhanjiswa kwi-X, Y okanye i-Z indlela. Ngokubanzi, ukugaya i-CNC kunokudala iimilo ezintsonkothileyo kunokuguqula i-CNC. Inokuvelisa iimveliso zecylindrical, kodwa inokuvelisa ezinye iimilo ezininzi. Kumatshini wokugaya we-CNC, i-chuck isetyenziselwa ukulungisa isixhobo kwi-spindle ejikelezayo. Isixhobo sokusika siya kuhanjiswa ukuba senze iphethini phezu kwendawo yokusebenza. Ukugaya kunomda omkhulu. Oku malunga nokuba isixhobo sinokungena kwindawo yokusika. Ukusebenzisa izixhobo ezibhityileyo nezinde kunokuphucula ukusondela, kodwa ezi zixhobo zinokuphambuka, nto leyo ekhokelela kumgangatho ophantsi wemveliso.
