Magwiridwe a Ceramic Alumina Abrasive Particles amatha kupitilizidwa powonjezera aluminiyamu yosungunuka pang'ono kuti apange mawilo ophatikizika. Panthawiyi, m'pofunika kudziwa kutalika kwa arc arc ya gudumu lopera pa workpiece, kuti mudziwe kuchuluka kwa gudumu. Silicon carbide: SiC abrasive ili ndi mawonekedwe akuthwa mwachilengedwe. Zoyenerakugayazinthu zolimba (monga simenti carbide). Chifukwa chakuthwa kwake, ndizoyeneranso kukonza zida zofewa kwambiri, monga aluminiyamu, ma polima, mphira, chitsulo chochepa mphamvu, ma aloyi amkuwa ndi mapulasitiki.
Daimondi: Ma diamondi achilengedwe komanso opangidwa amatha kugwiritsidwa ntchito popera. Daimondi ndi mtundu wovuta kwambiri wa carbon. Chifukwa imakhala ndi mgwirizano ndi chitsulo (chitsulo ndi aloyi wachitsulo ndi carbon) ndipo imapanga kuvala mofulumira, si yoyeneramakinazida zachitsulo, koma diamondi ndiyoyenera kwambiri pogaya zinthu zopanda chitsulo, titaniyamu, zoumba ndi cermets. CBN: Monga diamondi, CBN ndi abrasive okwera mtengo kwambiri.
Mtengo wa gudumu la abrasive super hard abrasive nthawi zambiri kuposa 50 kuposa gudumu wamba, koma moyo wake wautumiki umaposa nthawi 100 kuposa gudumu wamba la abrasive. Ngakhale chitsulo cholimba kwambiri chitakhala pansi, chimang'ambika pang'ono. CBN ndiyoyenera kwambirimakinagzipangizo zachitsulo, makamaka pamene mawonekedwe a gudumu akupera ayenera anakhalabe kwa nthawi yaitali, monga akupera wa mpikisano wonyamula katundu. Kuphatikiza apo, CBN ndiyoyeneranso kusinthira magudumu osasinthika, chifukwa magulu ang'onoang'ono ndikusintha magudumu amafunikira kuvala pakuyika, chomwe ndichomwe chimatsogolera kugwiritsa ntchito magudumu.
Chifukwa CBN idzachitapo kanthu ndi madzi kutentha kwambiri ndikufulumizitsa kuvala, ethylene glycol kapena mafuta ayenera kugwiritsidwa ntchito. Mgwirizano wambakugayagudumu litha kukhala ceramic, utomoni kapena pulasitiki, pomwe chomangira chapamwamba cholimba kwambiri chimatha kuphimbidwa pa gudumu logaya ndi masanjidwe achitsulo a sintered kapena electroplating nickel wosanjikiza. Mtundu woterewu wa gudumu lopera ndi wosalowetsedwa komanso wopanda mapanga.
Thekugayamadzimadzi achitsulo chomangira ndi electroplated gudumu akupera ayenera mosamala anasankha kupewa gudumu akupera kutsetsereka. Kuthamanga kwakukulu kwamphamvu kwa hydraulic komwe kumapangidwa pa arc yodulira panthawi yotsetsereka kumakweza gudumu lopera, zomwe zimabweretsa kuwonongeka kwa chogwirira ntchito komanso kuthamanga kwa magudumu opera.
