1, ukuthengwa kwabathengisi be-CNC blade kuye kwacindezelwa ukugqokwa kwama-CNC blade, ama-chips abrasive wear noma amaphuzu amancane aqinile ebusweni bomsebenzi (njenge-carbide, i-oxide, njll.) kanye nokungcola (okufana nesihlabathi, i-oxide , njll.), kanye nokunamathela kwemfucumfucu ye-chip tumor, njll., ukugqokwa komshini okubangelwa ama-grooves aqoshwe ebusweni be-CNC blade.Ngamathuluzi ensimbi enesivinini esikhulu anejubane eliphansi elilindelekile kanye nezinga lokushisa eliphansi lokusika (njenge-broach, die, tap, njll.), iyimbangela ebaluleke kakhulu yokuguga.
2. Ukunamathela okunamathelayo kwenza ukuthintana okusha kwendawo ngaphansi kwengcindezi enhle kanye nezinga lokushisa lokusika phakathi kwethuluzi elingemuva leblade ye-CNC kanye nendawo yokusebenza kanye nobuso bethuluzi langaphambili leblade ye-CNC namashiphu.Lapho indawo yokuxhumana ifinyelela ebangeni le-interatomic, kwenzeka isibopho se-adsorption.Iphuzu elihlangene lisikwa kancane kancane futhi lidatshulwe yi-workpiece noma ama-chips, futhi ingaphezulu le-CNC blade lizokhiqiza ukunamathela okunamathelayo.Ukugqoka okunamathelayo kungenye yezizathu eziyinhloko zokugqoka i-carbide enosimende lapho usikwa ngesivinini esiphakathi nesiphansi.
I-3, ukugqokwa kokusabalalisa ekushiseni okuphezulu, ukucindezela okukhulu, i-CNC blade material kanye nezinto zokusebenza ezisesimweni esiqinile sezakhi zamakhemikhali ekusakazeni okuncane okuhlangene, okungukuthi, i-tungsten carbide Ti, w, Co nezinye izakhi ezifana nokusabalalisa kwensimbi, kanye i-workpiece Fe, C nezinye izakhi ku-CNC blade diffusion, okuholela ebukhuni bendawo yethuluzi, ukwehla kokufunda okunamandla, ukwanda kokuqina, ukuqina kokugqoka kwamathuluzi.Lokhu kwaziwa njengokugqokwa kokusabalalisa, futhi ukugqokwa kokusabalalisa kungesinye sezizathu eziyinhloko zokugqokwa kwamathuluzi okusika i-carbide enosimende emazingeni okushisa aphezulu (800″900°C).
I-4, ngokuvamile i-W, izinga lokusabalalisa le-Co lishesha kune-Ti, Ta, ngakho-ke izinga lokushisa eliphezulu lokusika ukusebenza kwe-YT class cemented carbide kungcono kune-YG class.Ukugqoka koshintsho lwesigaba Lapho usikwa ngamathuluzi ensimbi anesivinini esikhulu, lapho izinga lokushisa lokusika lidlula izinga lokushisa lokushintsha kwesigaba (550″600 ° C), ukwakheka kwe-metallographic ye-CNC blade kuzoshintsha, ukuze ukuqina kuzokwehla futhi ukuguga kuzosheshisa. , ngakho-ke ukugqoka kwesigaba sokushintsha kungenye yezizathu eziyinhloko zokugqoka insimbi ye-CNC yensimbi enesivinini esikhulu.Ukugqokwa kwamakhemikhali Emazingeni athile okushisa, imidiya ezungeze indawo yokusika, njengomoya, uketshezi olunqamulayo, njll., iphendula ngamakhemikhali nento yamathuluzi ukuze yenze izinhlanganisela ezixegayo nezintekenteke.Lezi zinhlanganisela kulula ukusikwa futhi i-workpiece ihuzuke, okuholela ekugugeni kwe-CNC blade.
