Guhindura Uburyo bwo Gukata: Polycrystalline Cubic Boron Nitride (PCBN)
Ibikoresho bya polycrystalline cubic boron nitride (PCBN) ni ibikoresho byo gukata bifite imikorere myiza bizwiho gukomera cyane, kudapfa kwangirika, no gutwara ubushyuhe neza. Ibi bituma PCBN iba nziza mu gutunganya neza ibikoresho bigoye nka ceramic, ibyuma bikomeye, n'ibyuma bikomeye. Ugereranyije n'ibikoresho bisanzwe byo gukata, Ibikoresho bya Pcbn bitanga uburyo bwo guca neza no kunoza imikorere, bikongera umusaruro kandi bikaba umutungo w'ingenzi mu nganda zikora.
Isahani ya Pcbn Composites zubatswe hakoreshejwe substrate ikomeye ya alloy, zirimo ifu nto ya cubic boron nitride (CBN), kandi zigashyirwa mu bushyuhe bwinshi n'umuvuduko. CBN ifite ubukana bwa kabiri nyuma ya diyama, ifite ubushyuhe buhamye kandi irwanya imiti irenze kure iya diyama, bigatuma iba ihangane cyane mu gutunganya ibyuma bishingiye ku cyuma. Ibi bishyira PCB nk'amahitamo y'ingenzi mu gukoresha ibikoresho byo gukata no gukata.
Imiterere yihariye y'ibice bya PCBN bivanze ntabwo itanga ubukana budasanzwe n'ubushyuhe burambye gusa, ahubwo inanongera ubukana binyuze mu gice cy'icyuma gikomeye, bikoroshya gutunganya. Ikoreshwa ryabyo ni rinini, rikubiyemo imashini za CNC zigezweho, ibikoresho by'imashini byikora, n'imirongo yihuta yikora. PCBN ikoreshwa cyane mu gutunganya ibyuma bikomeye, ibyuma bikonje, ibyuma by'ibikoresho, n'ibice bikomeye, buhoro buhoro bisimbura ibikoresho bisanzwe bikomeye n'ibikoresho bya ceramic kandi bivamo nk'icyerekezo gikuru mu nganda z'ibikoresho byo gukata.
1. Imiterere y'iterambere ry'amasahani ya PCBN Composite Plates muri iki gihe
Iterambere ry'ibikoresho bya PCBN rirateye imbere cyane mu turere nk'i Burayi, Amerika ya Ruguru, n'Ubuyapani, aho hashyizweho uburyo bwa tekiniki bugezweho. Ibicuruzwa birushaho kurangwa no gutandukana, kunoza ireme, no gukora neza. Ibikoresho bya PCBN biva mu mahanga bikunze kuba bihamye ku gipimo kiri hejuru ya mm 50, aho Element Six itanga ibicuruzwa bifite umurambararo wa mm 57 na mm 101.6 by'imibiri ya CBN sintered bodies (AMB90), bigakomeza kwangirika no kugabanuka k'ubushyuhe muri 30% kugira ngo bigire imiterere idasanzwe. DI na Sumitomo bitanga ibisobanuro bya mm 50.8, mm 58, na mm 64, uko bikurikirana.
Boreas imaze imyaka myinshi ikora plaque za PCBN zifite umurambararo wa mm 64 nyuma y’ubushakashatsi bwinshi, zifite ingano iri hagati ya 2μm na 15μm. Dutanga ibyiciro birenga 20 bitandukanye by’ibisubizo byihariye kugira ngo bihuze n’ibikenewe mu gutunganya. Uhisemo plaque za PCBN za Boreas, uzabona iterambere rikomeye mu mikorere myiza no mu bwiza!
