Zinthu zapakati pobowola zitha kugawidwa mu zitsulo zothamanga kwambiri, carbide yoyimitsidwa, zoumba ndi diamondi ya polycrystalline.Pakati pawo, chitsulo chothamanga kwambiri ndi chinthu chomwe chimagwiritsidwa ntchito kawirikawiri ndi ntchito yotsika mtengo;carbide simenti ali wabwino kuvala kukana ndi kuuma, ndipo ndi oyenera processing zipangizo ndi mkulu kuuma;Ceramic pakati kubowola ali wabwino kutentha kukana ndi kuvala kukana, koma processing Mwachangu ndi otsika;pobowola diamondi pakati polycrystalline ali kopitilira muyeso-mkulu kuuma ndi kuvala kukana, ndi oyenera pokonza mkulu-kuuma zipangizo.Posankha pakati pobowola zakuthupi, ayenera kusankhidwa molingana ndi kuuma workpiece zakuthupi ndi zinthu processing.Nthawi zambiri, pazinthu zachitsulo zolimba, mutha kusankha zida zolimba, monga simenti ya carbide, diamondi ya polycrystalline, etc.;kwa zipangizo zofewa, mungasankhe zitsulo zothamanga kwambiri kapena zoumba.Komanso, m'pofunikanso kulabadira zinthu monga kukula ndi pamwamba khalidwe la pakati kubowola kuonetsetsa processing kwenikweni ndi processing kulondola.Mukamagwiritsa ntchito pobowola pakati, chidwi chiyenera kuperekedwa pakukonza mafuta ndi kuziziritsa kuti mupewe kuvala kwa zida komanso kutsika kwapamwamba chifukwa chakuchulukirachulukira.Pa nthawi yomweyo, tiyenera kulabadira chitetezo pa processing kupewa kusakhazikika workpiece kapena ngozi processing chifukwa otsika processing olondola.
