PCD: Chisankho Chabwino Kwambiri Pakupanga Ma Aluminium Workpieces

Zipangizo za Polycrystalline Diamond (PCD) zimapereka ubwino wapadera pa ntchito zogwirira ntchito za aluminiyamu, kuphatikizapo nthawi yayitali ya zida komanso kuchuluka kwa zochotsa zitsulo. Komabe, mtengo wawo woyamba ukhoza kukhala wokwera, zomwe zingayambitse ndalama zambiri zogwirira ntchito. Zipangizo za aluminiyamu masiku ano zasintha kwambiri, ndipo pokonza zinthu zosiyanasiyana za aluminiyamu zatsopano—makamaka zipangizo zopangidwa ndi silicon yambiri—ndikofunikira kusankha mosamala magawo oyenera a zida za PCD ndi geometric kuti ziwongolere kupanga bwino komanso kukonza bwino. Mwamwayi, chifukwa cha mpikisano wamsika ndi kupita patsogolo kwa njira zopangira, mtengo wa Zida za PCD yatsika ndi oposa 50%, zomwe zapangitsa kuti ikhale yosavuta kupeza.

Zinthu Zofunika Kwambiri pa Zida za PCD

Ma PCD composite inserts amapangidwa ndi diamondi yosungunuka ndi chothandizira kutentha kwambiri komanso kupanikizika, zomwe zimapangitsa kuti pakhale kapangidwe kapadera kolumikizana ndi "milatho" ya tinthu ta diamondi. Njirayi imapanga kapangidwe ka catalyst, kofanana ndi zinthu za diamondi za monolithic. Mosiyana ndi PCBN (Polycrystalline Cubic Boron Nitride), yomwe ilibe zinthu zomangira pakati pa tinthu ta CBN, PCD ili ndi kapangidwe ka coalescent komwe tinthu ta diamondi timalumikizidwa kudzera m'milatho ya lattice.

Magiredi a zida za PCD amagawidwa m'magulu malinga ndi kukula kwa tinthu ta diamondi. Malinga ndi miyezo yamakampani, magiredi a PCD osalala, apakatikati, ndi osalala amafanana ndi kukula kwa tinthu ta 2 μm, 10 μm, ndi 25 μm motsatana. Magiredi a PCD osalala amakhala ndi mphamvu zambiri komanso kukana kuwonongeka, zomwe zimapangitsa kuti zida zizikhala nthawi yayitali panthawi yokonza zinthu mosasamala. Komabe, m'mphepete mwa zida za PCD zosalala sizingakwaniritse bwino mawonekedwe ake osalala omwe angapezeke ndi zida za PCD zosalala, zomwe, ngakhale zikupereka mawonekedwe abwino kwambiri, zimatha msanga.

Zida Zodulira za PCD Ndi abwino kwambiri pogwiritsira ntchito monga masamba a diamondi, kubowola ndi kukumba, zodulira diamondi m'mphepete, zosinthira ndi zopukutira, ndi zobowola diamondi zobowola mabowo mu zipangizo zophatikizika ndi mabwalo ozungulira.

Boreas imapanga zida za PCD zodziwika bwino chifukwa cha makhalidwe awo abwino komanso kugwiritsa ntchito bwino zinthu zosiyanasiyana, zonse pamodzi ndikusunga mitengo yopikisana. Ngati mukufuna kukulitsa luso lanu lopanga makina, Boreas ndiye chisankho chanu chabwino kwambiri cha zida za PCD zapamwamba zomwe zimagwira ntchito bwino komanso zopindulitsa.
