Gudumu lakuda la silicon carbide limapangidwa ndi mchenga wa giredi yoyamba, kuvala zolimba silicon carbide ndi binder pa kutentha kwambiri sintered, Imatchedwanso ceramic grinding wheel.Zosavala, zolimba, zolimba (wilo lopukutira losakwanira ndi mchenga wobwezeredwa). Ndiwolimba kwambiri, kulimba kwambiri, njere zakuthwa zotsekemera komanso kuwongolera kwamafuta abwino.
