Pakudula, ufa wa diamondi micro wakhala chinthu chofunikira kwambiri, makamaka muukadaulo wapamwamba wodulira monga Diamond Wire Saw. Boreas, wopanga wotsogola wa...

Pakati pa mitundu yosiyanasiyana ya zipangizo zamafakitale, ufa wa diamondi umadziwika ngati chinthu chosinthika komanso chofunikira kwambiri chifukwa cha mawonekedwe ake apadera komanso kugwiritsa ntchito kwake kwakukulu. Koma kodi ndi chiyani ...

Daimondi, yodziwika chifukwa cha kuuma kwake kwapadera komanso kutentha kwake, ndi chinthu chofunikira kwambiri m'mafakitale osiyanasiyana, kuphatikizapo zida zopukutira, zodulira, ndi zopera. Zonse ziwiri ndi monocrystal...

Mtundu wa diamondi womwe umagwiritsidwa ntchito popera ndi kupukuta zakumwa umakhudza kwambiri magwiridwe antchito a chinthu chomaliza. Ma diamondi amafakitale amagawidwa m'magulu achilengedwe ndi opanga, ...

Zida za Polycrystalline Diamond (PCD) zimapereka ubwino wapadera pa ntchito zomangira aluminiyamu, kuphatikizapo nthawi yayitali ya zida komanso kuchuluka kwa zochotsa zitsulo. Komabe, mtengo wawo woyamba ukhoza kukhala wokwera...

Mapepala opangidwa ndi polycrystalline cubic boron nitride (PCBN) ndi zinthu zodulira zomwe zimadziwika ndi kuuma kwawo kwapadera, kukana kuvala bwino, komanso kutentha kwambiri...

Ma PCBN composite inserts ali ndi kuuma pang'ono kwa 2700-5000 HV, yachiwiri pambuyo pa diamondi ndipo ndi apamwamba kwambiri kuposa silicon carbide ndi aluminiyamu oxide. Kukana kwawo kukalamba ndi kokulirapo nthawi 50 kuposa...

Ponena za kukwaniritsa ntchito yabwino kwambiri pakupanga makina, kusankha zida zodulira diamondi ndikofunikira kwambiri. Ma diamondi a kristalo imodzi, PCD (kapena PCD/CC), ndi ma diamondi a CVD ndi omwe amatsogolera...

Malamba opukutira mchenga, odziwika bwino chifukwa cha luso lawo lopukutira mosasinthasintha, amapereka zabwino zambiri kuposa zopukutira zomangiriridwa (monga mawilo opukutira), kuphatikizapo kupanga kutentha kochepa, komanso mphamvu zambiri...

Zipangizo za PCD, zomwe zimakhala zolimba kwambiri komanso zosagwirizana ndi kuwonongeka, zimakhala ndi mawonekedwe okhwima kwa nthawi yayitali panthawi yodula magalasi. Izi zimachepetsa kuchuluka kwa zida zomwe zimasinthidwa...
