I-Superhard Tool material ibhekisela ezintweni ezinzima kakhulu ezingasetshenziswa njengethuluzi lokusika. Njengamanje, ingahlukaniswa ngezigaba ezimbili: ithuluzi lokusika idayimane kanye ne-cubic boron nitride cutting tool material. Kunezinhlobo ezinhlanu eziyinhloko zezinto ezintsha ezisetshenzisiwe noma ezivivinywayo
(1) Idayimane lekristalu elilodwa lemvelo nelokwenziwa
(2) I-Poly diamond (PCD) kanye ne-poly diamond composite blade (PDC)
(3) Idayimane le-CVD
(4) I-polycrystal cubic boron ammonia; (PCBN)
(5) I-CVD cubic boron ammonia coating
1, idayimane elikhulu lekristalu lemvelo nelokwenziwa
Idayimane lemvelo liyisakhiwo sekristalu esifanayo ngaphandle komngcele wangaphakathi wokusanhlamvu, ukuze unqenqema lwamathuluzi lukwazi ukufinyelela ngokunembile ukushelela kwe-athomu nobukhali, ngekhono eliqinile lokusika, ukunemba okuphezulu namandla amancane okusika. Ukuqina, ukumelana nokugqoka kanye nokumelana nokugqwala kanye nokuzinza kwamakhemikhali edayimane yemvelo kuqinisekisa impilo ende yethuluzi, kungaqinisekisa ukusika okujwayelekile okude, futhi kunciphise umthelela wokugqoka kwamathuluzi ekunembeni kwezingxenye ezicutshunguliwe, ukuqhutshwa kwayo okuphezulu okushisayo kunganciphisa izinga lokushisa lokusika kanye nokuguqulwa okushisayo kwezingxenye. Izici ezinhle zedayimane lekristalu elikhulu lemvelo elikhulu zingahlangabezana nezidingo eziningi zokunemba nokusika okunembe kakhulu kwezinto zamathuluzi. Nakuba intengo yayo ibiza kakhulu, isaqashelwa njengokunemba okufanelekile kanye nezinto ezisetshenziswayo zokunemba kwe-Ultra, ingasetshenziswa kabanzi ekucubunguleni ama-reactors enuzi nobunye ubuchwepheshe obuphakeme emkhakheni wezibuko, imicibisholo namarokhethi, i-hard disk substrate yekhompyutha, i-accelerator electron gun super precision machining, kanye nezingxenye zewashi lendabuko, ubucwebe, amapeni, iphakheji yensimbi yomhlobiso osetshenziswayo ukucutshungulwa kobuchopho, njll. i-scalpel, ama-ultra-thin biological blades namanye amathuluzi ezokwelapha. Ukuthuthukiswa kwamanje kokushisa okuphezulu kanye nobuchwepheshe bokucindezela okuphezulu kwenza kube lula ukulungiselela idayimane elikhulu elilodwa le-crystal enobukhulu obuthile. Inzuzo yaleli thuluzi ledayimane liwusayizi walo omuhle, ukuma nokusebenzaOkungaguquguquki, okungatholakali emikhiqizweni yedayimane yemvelo. Ngenxa yokushoda kokunikezwa kwedayimane lemvelo ngobukhulu obukhulu, intengo ebizayo, izinto zokwenziwa zethuluzi ledayimane eliyikristalu elikhulu ekucutshungulweni kokusika okunembayo njengengxenye yedayimane enkulu yekristalu eyodwa, ukusetshenziswa kwayo kuzothuthukiswa ngokushesha.
2, idayimane le-polycrystal (PCD) kanye ne-polycrystal diamond composite blade (PDC) uma kuqhathaniswa nedayimane elikhulu eliyikristale elilodwa njengethuluzi le-polycrystal diamond (PCD) kanye ne-polycrystal diamond composite blade (PDC) kunezinzuzo ezilandelayo: (1) ukuhlelwa kokuphazamiseka kokusanhlamvu, isotropic, akukho ndawo eqhekekile. Ngakho-ke, akufani nedayimane elikhulu lekristalu elilodwa kumandla ahlukene wekristalu, ubulukhuni
Futhi ukumelana nokugqoka kuhluke kakhulu, futhi ngenxa yokuba khona kwe-cleavage surface futhi i-brittle.
(2) inamandla aphezulu, ikakhulukazi ithuluzi le-PDC impahla ngenxa yokusekelwa kwe-matrix ye-carbide futhi inokumelana nomthelela omkhulu, umthelela uzokhiqiza kuphela okusanhlamvu okuncane okuphukile, hhayi njengokuwa kwe-crystal eyodwa yedayimane elikhulu, ngaleyo ndlela nge-PCD noma ithuluzi le-PDC hhayi kuphela elingasetshenziswa ukusika ukunemba kanye nengxenye evamile yokunemba kwesigamu. Kodwa futhi ingasetshenziswa njengesamba esikhulu somshini onzima nokucubungula ngezikhathi ezithile (njengokugaya, njll.), okwandisa kakhulu uhla lokusetshenziswa kwezinto zethuluzi ledayimane.
(3) Ithuluzi elikhulu le-PDC elingenalutho lingalungiselelwa ukuhlangabezana nezidingo zamathuluzi amakhulu okwenza imishini njengesisiki sokugaya.
(4) Amajamo athile angenziwa ukuze ahlangabezane nezidingo zokucubungula okuhlukile. Ngenxa yokuthuthukiswa kwe-PDC tool billet kanye nobuchwepheshe bokucubungula njengenhlansi kagesi, ubuchwepheshe bokusika i-laser, unxantathu, i-herringbone, ama-gables kanye nezinye i-blade billet emise okukhethekile ingacutshungulwa futhi yakheke. Ukuze kuhlangatshezwane nezidingo zamathuluzi okusika akhethekile, kungabuye kuklanywe njenge-billet egoqwe, isangweji kanye ne-roll PDC tool.
(5) Ukusebenza komkhiqizo kungaklanywa noma kubikezelwe, futhi umkhiqizo unikezwa izici ezidingekayo ukuze uzivumelanise nokusetshenziswa kwawo okuthile. Isibonelo, ukukhetha impahla yethuluzi le-PDC enezinhlamvu ezinhle kungathuthukisa ikhwalithi yonqenqema yethuluzi; Ithuluzi le-PDC elimahhadla-grained lingathuthukisa ukuqina kwethuluzi.
Sengiphetha, ngokuthuthukiswa kwezinto zamathuluzi e-PCD ne-PDC, ukusetshenziswa kwethuluzi le-PCD ne-PDC kuye kwanwetshwa ngokushesha kwabakhiqizi abaningi.
Imboni isetshenziswa kabanzi izinsimbi non-ayoni (aluminium, aluminium ingxubevange, ithusi, ingxubevange yethusi, magnesium ingxubevange, zinc ingxubevange, njll.), carbide, zobumba, izinto ezingezona metallic (plastic, injoloba kanzima, carbon izinduku, ukhuni, imikhiqizo usimende, njll.), izinto eziyinhlanganisela (ezifana fibre composite CF, ipulasitiki ukusika composite, MMCs ipulasitiki ukusika composite eqinile, izimoto kanye nezinkuni processing imboni, isibe high ukusebenza ehlukile carbide bendabuko.
