Izinzuzo Zokusebenzisa Umshini we-EDM
I-Pendahuluan
Imishini Yokukhipha Ugesi (i-EDM) ingenye yezobuchwepheshe obusha kakhulu ekukhiqizeni kwesimanje. Imishini ye-EDM isebenzisa izinhlansi zikagesi ukususa izinto ezisetshenziswayo, okwenza zibe usizo ekwakhiweni kwezingxenye ezidinga ukunemba okuphezulu. Ukusetshenziswa kwe-EDM kudlulela ngale kwemboni yezimoto kuya emikhakheni ye-semiconductor, yezindiza, kanye neyezokwelapha. Lesi sihloko sizochaza izinzuzo ezahlukahlukene ezingatholakala ngokusebenzisa imishini ye-EDM ezinqubweni zokukhiqiza.
Ukunemba Okuphezulu Nokunemba
Enye yezinzuzo eziyinhloko zemishini ye-EDM yikhono layo lokusika izinto ngokunemba okuphezulu kakhulu. Ngokusebenzisa ama-electrode akhiwe ngendlela oyifisayo, imishini ye-EDM ingakhiqiza izingxenye ezinobukhulu obuqondile kakhulu kanye nezindawo ezibushelelezi. Lokhu kubaluleke kakhulu ezimbonini ezidinga ukubekezelelwa okuqinile, njengokubumba umjovo wepulasitiki, imishini yokucindezela, nezinye izingxenye ezenziwe ngomshini ngokunemba.
Imishini ye-EDM iyakwazi ukukhiqiza imininingwane emincane kakhulu futhi ingasebenza esikalini se-micron. Lokhu kuwusizo kakhulu lapho usebenza ngezinto okunzima ukuzisika usebenzisa izindlela ezivamile njengokubhoboza noma ukugaya.
Ukuzivumelanisa nezimo kanye nomklamo oyinkimbinkimbi
Uma kukhulunywa ngemiklamo eyinkimbinkimbi kanye nezimo eziyinkimbinkimbi, imishini ye-EDM inikeza ukuguquguquka okumangalisayo. Ingakhiqiza izimo ezingenakwenzeka ngezinqubo zendabuko zomshini. Lokhu kuwusizo kakhulu ekudaleni ama-prototypes kanye nezingxenye ezenziwe ngokwezifiso ezine-geometries eziyinkimbinkimbi.
Isibonelo, embonini yokukhiqiza isikhunta, izimo eziyinkimbinkimbi zemigodi kanye nezimbobo ezincane kakhulu zingakhiwa kalula kusetshenziswa i-EDM. Ngokufanayo, embonini yezindiza kanye nezimoto, izingxenye ezinemiklamo eyinkimbinkimbi ne-aerodynamic zingakhiqizwa ngempumelelo enkulu.
Ikhono Lokusebenza Ngezinto Eziqinile
Imishini ye-EDM inekhono eliyingqayizivele lokusika izinto eziqinile okunzima noma okungenakwenzeka ukuzisebenzisa ngezindlela ezivamile zomshini. Ezinye zalezi zinto zifaka i-tungsten carbide, i-titanium, kanye nezinhlobo ezahlukene zensimbi eqinile. Lezi zinto zivame ukusetshenziswa ezimbonini ezidinga ukuqina okuphezulu namandla.
Ngenxa yokuthi i-EDM ayibandakanyi ukuthintana okuqondile ngokomzimba phakathi kwe-electrode kanye ne-workpiece, ingozi yokuguqulwa kwezinto ngenxa yokushisa noma ukucindezeleka komshini incane kakhulu. Lokhu kuqinisekisa ukuthi ubuqotho kanye nekhwalithi yezinto ezibonakalayo kugcinwa kuyo yonke inqubo yomshini.
Ukusebenza Kahle Kwamandla Nokonga Isikhathi
Imishini ye-EDM isebenza ngokusebenzisa ama-pulse kagesi alawulwa kahle, okunciphisa ngempumelelo isikhathi somshini uma kuqhathaniswa nezindlela ezivamile. Ukusebenza kwayo okuzenzakalelayo nokuqhubekayo kuvumela ukukhiqizwa okukhulu ngaphandle kokubhekwa okuncane.
Ngaphezu kwalokho, inqubo ye-EDM ayidingi amathuluzi okusika ayinkimbinkimbi futhi abizayo. Lokhu kunciphisa kakhulu izindleko zokusebenza nokulungisa imishini. Ngokusebenza kahle kwamandla okwandisiwe kanye nezikhathi zokucubungula ezisheshayo, ukusetshenziswa kwemishini ye-EDM kungaba nomthelela omuhle emazingeni okukhiqiza enkampani kanye nenani eliphansi lezezimali.
Ukunciphisa I-Voltage Esele kanye Nokuhlanekezelwa Kokushisa
Inkinga eyodwa evamile ezinqubweni zomshini wokugaya imishini ukucindezeleka okusele endaweni yokusebenza ngemva kokusika, okungabangela ukuphambuka kokushisa kanye nokuguquka kwezinto. Umshini wokugaya we-EDM ubhekana nale nkinga ngenqubo esekelwe ekugugulekeni kwe-electrothermal, lapho kungekho kucindezeleka komshini okusetshenziswa khona endaweni yokusebenza.
Le nqubo iqinisekisa ukuthi akukho ukucindezeleka okwakheka ezintweni ezingabeka engcupheni ukuzinza kanye nobuqotho besakhiwo somsebenzi. Lokhu kubaluleke kakhulu ekusetshenzisweni lapho ukuthembeka kanye nekhwalithi kubaluleke kakhulu, njengasekukhiqizweni kwezingxenye zezokwelapha nezezindiza.
Izinzuzo Zomshini Wokwenza Imigodi Emincane Nemincane
Umshini wokugaya we-EDM unenzuzo eyingqayizivele yomshini wokugaya imigodi emincane nemincane, okunzima kakhulu ukuyifinyelela ngezindlela zomshini ezivamile. Lezi zimbobo zivame ukusetshenziswa ezicelweni ezidinga ukugeleza koketshezi noma kwegesi okunembile kakhulu, njengemibhobho yokujova uphethiloli kanye nezingxenye ezincane ze-electromechanical.
Ngobuchwepheshe be-EDM, lezi zimbobo zingenziwa ngobubanzi obuncane kakhulu kanye nokujula okungaguquki, okuqinisekisa ukusebenza kahle ekusetshenzisweni kwazo kokugcina. Leli khono liwusizo kakhulu ekukhiqizweni kwamadivayisi ezokwelapha kanye nezingxenye ze-elekthronikhi ezidinga ukunemba okuphezulu.
Ukuthuthukiswa Kwekhwalithi Yomphezulu
Ikhwalithi yobuso iyisici esibalulekile ekukhiqizweni kwezingxenye ngokunemba, okuthinta kokubili ukusebenza kanye nobude besikhathi. Imishini ye-EDM yaziwa ngokukhiqiza izindawo zokusebenza ezibushelelezi kakhulu, ingashiyi zimpawu zokusika noma ama-burrs.
Umkhiqizo wokugcina ovela kumishini ye-EDM uvame ukuba nenani eliphansi kakhulu le-surface roughness (Ra), okwenza kube kuhle kakhulu ekusetshenzisweni lapho ikhwalithi yobuso ibaluleke kakhulu. Lokhu kufaka phakathi ukukhiqizwa kwesikhunta embonini yepulasitiki, edinga izindawo ezibushelelezi ukuze kukhiqizwe imikhiqizo yokugcina esezingeni eliphezulu.
Isiphetho
Ukusetshenziswa kwemishini ye-EDM ezinqubweni zokukhiqiza zesimanje kunikeza izinzuzo eziningi ezibalulekile uma kuqhathaniswa nezindlela zomshini ezivamile. Kusukela ekhonweni lokusika izinto eziqinile neziyinkimbinkimbi kuya ekuqondeni okuphezulu nasekuqondeni, imishini ye-EDM inikeza izixazululo ezisebenzayo nezisebenzayo zezinhlelo zokusebenza eziningi zezimboni.
Ukuguquguquka, ukusebenza kahle kwamandla, kanye nesivinini sokucubungula okusheshayo kwenza i-EDM ibe ithuluzi elibalulekile lokuthuthukisa umkhiqizo kanye nekhwalithi yomkhiqizo. Izimboni ezidinga ukubekezelelana okuqinile, imiklamo eyinkimbinkimbi, kanye nezinto eziqinile zingazuza kakhulu kulobu buchwepheshe, ekugcineni kube nomthelela omuhle ekukhuleni kwebhizinisi labo kanye nokusimama.
Ngokuqonda lezi zinzuzo, izinkampani zingenza kalula izinqumo ezihlakaniphile zokusebenzisa ubuchwepheshe be-EDM ukuze zihlangabezane nezidingo zazo zokukhiqiza ezishintshashintshayo.
