Kumathuluzi omshini we-CNC, izinto ezisetshenziswayo ezivame ukusetshenziswa zihlanganisaisivinini sensimbi,ingxubevange eqinile,i-ceramicfuthiamathuluzi anzima kakhululezi zigaba eziningana.
1.Insimbi yejubane eliphezuluiwuhlobo lwensimbi ephezulu ye-alloy, ehlanganiswa ngokungeza izakhi zensimbi ezengeziwe njenge-tungsten, i-molybdenum, i-chromium ne-vanadium ensimbi.Inezici zokuqina okuphezulu, ukumelana nokushisa okuqinile, ubulukhuni izikhathi ezimbili kuya kwezintathu ze-carbide evamile, ingamelana nokushisa okuphezulu kwama-degrees Celsius angu-650 ngaphandle kokuthinta ukusika.Ivamise ukusetshenziselwa ekucubunguleni insimbi engeyona ayoni, insimbi yesakhiwo, insimbi ekhonjiwe kanye nezinye izinto zokwakha.
2.Ingxubevange eqinileiwuhlobo lwemikhiqizo ye-powder metallurgy, yenziwe ngobulukhuni obuphezulu, i-refractory metal carbide kanye ne-metal binder sintering ngaphansi kwezimo zokushisa eziphezulu.Izinga lokushisa layo lokusebenza lingafinyelela ku-1000 degrees Celsius izinga lokushisa eliphezulu, nakuba amandla nokuqina kuphansi kunensimbi enesivinini esikhulu, kodwa impilo yesevisi ingeyakamuva izikhathi ezimbalwa, ngisho nezikhathi eziningi.Ivame ukusetshenziselwa ukucubungula izinhlobo eziningi zezinto ezifana nensimbi eqinile.
3.Ithuluzi elenziwei-ceramicizinto zokwakha ngaphezu kokuqina okuphezulu, ukumelana nokugqoka kanye nezakhiwo ezinhle zemishini yokushisa okuphezulu, inzuzo enkulu kunazo zonke izakhiwo zamakhemikhali ezizinzile, futhi ukuhlangana kwensimbi kuncane, akulula ukucutshungulwa nge-metal bonding, kungasetshenziswa ngesivinini esikhulu, isivinini esiphezulu. ukusika nokusika impahla eqinile.Insimbi, insimbi ekhonjiwe, ama-alloys nezinto ezinzima zivame ukusikwa ngamathuluzi e-ceramic.
4.Kunzima kakhulu izinto zokwakhabheka idayimane lokwenziwa, i-cubic boron nitride, nedayimane le-polycrystalline kanye ne-polycrystalline cubic nitride shed efakwe impushana ne-binder yalezi zinto.Njengoba sonke sazi, idayimane liyinto enzima kunazo zonke emvelweni.Ngakho-ke, izinto eziqinile kakhulu zinokuphikiswa okuhle kakhulu kokugqoka futhi zivame ukusetshenziselwa ukusika ngesivinini esikhulu kanye nezinto ezinzima zokusika.
