Ukuguqula Ukusebenza Kokusika Ngokuphumelelayo: I-Polycrystalline Cubic Boron Nitride (PCBN)

Amapuleti ahlanganisiwe e-polycrystalline cubic boron nitride (PCBN) ayizinto zokusika ezisebenza kahle kakhulu ezaziwa ngobulukhuni bazo obungavamile, ukumelana nokuguguleka okuvelele, kanye nokuqhuba kahle kokushisa. Lezi zakhiwo zenza i-PCBN ibe yindawo ekahle yokulungisa izinto ezinzima njenge-ceramics, izinsimbi eziqinile, kanye nama-alloy aqinile. Uma kuqhathaniswa namathuluzi okusika endabuko, Amathuluzi e-Pcbn inikeza ukunemba okuphezulu kokusika kanye nokusebenza kahle, okuthuthukisa kakhulu umkhiqizo futhi kube yimpahla ebalulekile embonini yokukhiqiza.

Ipuleti Elihlanganisiwe le-PCBNAma-s akhiwe nge-substrate eqinile ye-alloy, egqitshwe nge-cubic boron nitride (CBN) micro-powder, futhi ishiswe ngaphansi kokushisa okuphezulu kanye nengcindezi. I-CBN inesimo sobulukhuni esilandela idayimane kuphela, ngokuqina kokushisa kanye nokumelana kwamakhemikhali okudlula kakhulu okwedayimane, okwenza ibe ngumncintiswano omkhulu ekusetshenzisweni kwezinsimbi ezisekelwe ensimbini. Lokhu kubeka i-PCBN njengokukhetha okubalulekile kokubili ekusetshenzisweni kwamathuluzi okukhuhla kanye nokusika.

Umklamo oyingqayizivele wamapuleti e-PCBN ahlanganisiwe awugcini nje ngokuhlinzeka ngobulukhuni obungavamile kanye nokuzinza kokushisa kodwa futhi uthuthukisa ukuqina nge-substrate ye-alloy eqinile, okwenza kube lula ukuqhubeka nokucutshungulwa. Uhla lwazo lokusetshenziswa lukhulu, luhlanganisa imishini ye-CNC ethuthukisiwe, amathuluzi omshini azenzakalelayo ngokugcwele, kanye nemigqa ezenzakalelayo esheshayo. I-PCBN isetshenziswa kabanzi ekusetshenzisweni kwensimbi eqinile, insimbi ebandayo, izinsimbi zamathuluzi, kanye nezingxenye eziqinisiwe, kancane kancane ithatha indawo yama-alloy aqinile endabuko namathuluzi e-ceramic futhi ivele njengomkhuba ojwayelekile embonini yamathuluzi okusika.

1. Isimo Sokuthuthukiswa Kwamanje Kwama-PCBN Composite Plates

Ukuthuthukiswa kwamathuluzi e-PCBN kuthuthuke kakhulu ezifundeni ezifana neYurophu, iNyakatho Melika, neJapane, lapho kusungulwe khona uhlelo lobuchwepheshe oluvuthiwe. Imikhiqizo ichazwa kakhulu ngokuhlukahluka, ukwenziwa ngcono kwekhwalithi, kanye nokusebenza okufanayo. Amapuleti e-PCBN ahlanganisiwe avela phesheya avame ukuzinza kumadayamitha angaphezu kwama-50mm, kanti i-Element Six inikeza imikhiqizo enobubanzi obungu-57mm no-101.6mm wemizimba ehlanzekile ye-CBN sintered bodies (AMB90), egcina ukuguguleka nokusebenza kokushisa kungaphakathi kwama-30% ukuze kube nokuvumelana okumangalisayo. I-DI ne-Sumitomo zinikeza imininingwane engu-50.8mm, 58mm, kanye no-64mm, ngokulandelana.

I-Boreas iphumelele ukuthuthukisa amapuleti e-PCBN ahlanganisiwe anobubanzi obungu-64mm ngemuva kweminyaka yocwaningo, anobukhulu bezinhlayiya obusukela ku-2μm kuya ku-15μm. Sinikeza izigaba ezingaphezu kuka-20 ezahlukene zezixazululo ezenziwe ngokwezifiso ukuze kuhlangatshezwane nezidingo ezithile zomshini. Ngokukhetha amapuleti e-PCBN ahlanganisiwe e-Boreas, uzothola ukuthuthuka okukhulu kokubili ekusebenzeni kahle kokusika kanye nekhwalithi!
