When setting the conditions, start · Tool overhang length must be as short as possible to avoid chatter. When from half of the values of the standard cutting conditions and then increase 45° the tool overhang length is long, decrease the number of revolutions and feed. the value gradually while making sure the machine is running normally. 70° 85° 88° 90° Others H044 www.tungaloy.com
