Ukukhethwa kwamathuluzi we-CNC okokusebenza

Njengamanje, izinto ezisetshenziswa kabanzi zethuluzi le-CNC ikakhulu zifaka amathuluzi edayimane, amathuluzi we-cubic boron nitride, amathuluzi we-ceramic, amathuluzi aboshwe, amathuluzi we-carbide namathuluzi wensimbi asheshayo. Kunamabanga amaningi okusika amathuluzi nezinto zawo ziyahlukahluka kakhulu. izinkomba zokusebenza kwezinto ezahlukahlukene zethuluzi zibalwe ngezansi.Ithuluzi lokusika le-NC machining kufanele likhethwe ngokuya ngohlobo lomsebenzi kanye nohlobo lomshini.Ukukhethwa kwento yethuluzi lokusika kufanele kube okuqondakalayo ngokufana kwento yokucubungula, ithuluzi lokusika impahla kanye ukufana kwento yokucubungula, ikakhulukazi kubhekiswa kuzakhiwo zemishini, izakhiwo zomzimba nezakhiwo zamakhemikhali zomdlalo womabili, ukuze kutholakale isikhathi eside kakhulu sethuluzi kanye nomkhiqizo omkhulu wokusika.

Ukufaniswa kwensimbi yensimbi yokusika ngezinto zomshini wezinto zemishini Ukufaniswa kwensimbi yensimbi yokusika enezakhiwo zemishini yokwenza izinto ikakhulu kubhekisa ekufaniseni ithuluzi lokusika nezinto zomshini ezinjengezikhwepha, ukuqina nobulukhuni bezinto zokusebenza. izakhiwo ezihlukile zemishini zilungele izinto ezahlukahlukene zokusebenza (1) ukulandelana kobunzima bezinto zethuluzi yile: ithuluzi ledayimane> ithuluzi le-cubic boron nitride> ithuluzi le-ceramic> i-carbide> i-high speed steel. Ukugoba kwamandla ukulandelana kwezinto zethuluzi yile:> isivinini esikhulu i-steel carbide> ithuluzi le-ceramic> ithuluzi ledayimane ne-cubic boron nitride. (3) i-oda lokuqina kwento yethuluzi yile: insimbi ephezulu> i-carbide> i-cubic boron nitride, idayimane namathuluzi we-ceramic. ngethuluzi ngobulukhuni obuphakeme. Ubulukhuni bezinto zethuluzi kumele bube ngaphezulu kobulukhuni bento yokusebenza, ngokuvamile edingeka ukuthi ibe ngaphezu kwe-60HRC. Into yethuluzi enzima kakhulu, kungcono ukumelana kwayo nokugqoka kuzoba yisibonelo, lapho inani le-cobalt ku-carbide eqinisekisiwe ukwanda, amandla ayo nobulukhuni kuyanda nobulukhuni buyancipha, futhi ilungele ukwenza imishini emimbi.Uma okuqukethwe kwe-cobalt kuncipha, ukuqina kwayo nokugqoka ukumelana kuyanda, futhi kufanelekile ukuqedela.Amathuluzi anezinto ezinhle kakhulu zokushisa okushisa kakhulu ukusika ngejubane eliphezulu.Ukusebenza okuphezulu kokushisa kwamathuluzi okusika e-ceramic kubenza bakwazi ukusika ngejubane elikhulu, okuyisikhathi esiphindwe ka-2 ~ 10 ngokushesha kune-carbide.

Izinto zokusika zensimbi nezakhiwo zomzimba wento yokucubungula zifanisa amathuluzi anezakhiwo ezahlukahlukene zomzimba, njenge, ukuqhutshwa okuphezulu kokushisa nendawo yokuncibilika ephansi yamathuluzi ensimbi ashesha kakhulu, iphuzu lokuncibilika okuphezulu nokwandiswa okushisayo okushisayo kwamathuluzi e-ceramic, ukuqhutshwa okuphezulu okushisayo nokwanda okushisayo okushisayo kwamathuluzi edayimane, njll., efanelekile ukucubungula izinto zokwenziwa zihlukile.Lapho kusetjenziswa owokusebenza ngokungahambi kahle kokushisa okushisayo, into yethuluzi enokuhanjiswa okuhle okushisayo kufanele isetshenziselwe ukwenza ukushisa okusikile kusabalale ngokushesha futhi unciphise ukusika kwezinga lokushisa.Ngenxa yokushisa okuphezulu okushisayo nokusabalalisa okushisayo, idayimane kulula ukukhishwa emlilweni wokusika futhi ngeke ikhiqize ukusonteka okukhulu okushisayo, okubaluleke kakhulu kumathuluzi wokunemba wokucacisa anezidingo zokunemba okuphezulu. ukushisa kwamathuluzi ahlukahlukene: ithuluzi ledayimane 700 ~ 8000C, ithuluzi le-PCBN 13000 ~ 15000C, c Ithuluzi le-eramic 1100 ~ 12000C, i-TiC (N) i-carbide eqinisekisiwe engu-900 ~ 11000C, i-WC isisekelo se-carbide esinezinsimbi ezinomsoco 800 ~ 9000C, i-HSS 600 ~ 7000C. Ukuhleleka kokushisa okushisayo kwezinto ezahlukahlukene zamathuluzi: I-PCD> PCBN> I-WC iqinisiwe I-carbide> I-TiC (N) i-carbide enamathele> I-HSS> i-ceramic e-si3n4-based> i-ceramic e-a1203. Ukuhleleka kwe-coefficient yokwanda okushisayo kwezinto zamathuluzi ahlukahlukene ngu: HSS> WC usimende okhanyisiwe> I-TiC (N)> A1203 base ceramic> PCBN > I-Si3N4 base ceramic> I-PCD. I-oda lokumelana nokushaqeka okushisayo kwezinto ezahlukahlukene zethuluzi yi-HSS> WC hard alloy> si3n4-base ceramic> PCBN> PCD> TiC (N) hard alloy> a1203-base ceramics.

Inkinga efanayo yokunquma ithuluzi lokusebenza kanye nempahla yamakhemikhali yento yokucubungula ikakhulukazi ibhekisa ekufanisweni kwemingcele yempahla yamakhemikhali njengokuhlangana kwamakhemikhali, ukusabela kwamakhemikhali, ukusakazeka nokonakala kwensimbi yensimbi yokusika kanye nempahla yokusebenza. izinto zethuluzi elifanele ukucubungula izinto zokwenziwa zihlukile. (1) zonke izinhlobo zokusika ithuluzi lokunamathela kokushisa (nensimbi) le-PCBN> i-ceramic> i-carbide ehlanganisiwe> i-HSS. (2) izinga lokushisa lokumelana namachibi ezintweni ezahlukahlukene zokusika ithuluzi kungokulandelayo: i-ceramic> PCBN> i-carbide diamond> i-HSS Amandla okusabalalisa okwenziwe nge-cutter (yensimbi) yi-diamond> si3n4-base ceramic> PCBN> a1203-base ceramic. Amandla okusabalalisa (kuya ku-titanium) kwakuyi-a1203- isisekelo sobumba> PCBN> SiC> Si3N4> idayimane.
Ukukhuluma ngokujwayelekile, i-PCBN, amathuluzi we-ceramic, i-carbide eboshiwe namathuluzi we-TiCN base carbide afanele ukucutshungulwa kwamanani we-ayoni.
