Kunola kwa macheka a tungsten carbide kumachitika pamakina a CNC oyendetsedwa ndi ma multi-axis pogwiritsa ntchito gudumu la diamondi. Timagwiritsa ntchito mawilo a diamondi abwino kwambiri ndi makina a Vollmer Sharpening kuti tikule bwino kwambiri. Chifukwa chake masamba athu a ma saw omwe ali ndi magwiridwe antchito abwinoko omwe amapanga kumaliza kosalala popanda kupukuta. Ndipo makina athu opukutira amtundu wamtundu wa carbide opukutira mano a carbide amawona masamba owoneka bwino nthawi zonse.
