When chips stay in the cutting zone during slotting or pocketing, use air blast to remove chips from the work area
Tool overhang length must be as short as possible to avoid chatter. When the tool overhang length is long, decrease the number of revolutions and feed
The above table shows the conditions for standard shank type cutters. When using long shank type cutters, the number of teeth may be different.
Cutting conditions are generally limited by the rigidity and power of the machine and the rigidity of the workpiece. When setting the conditions, start from half of the values of the standard cutting conditions and then increase the value gradually while making sure the machine is running normally

When chips stay in the cutting zone during slotting or pocketing, use air blast to remove chips from the work area
Tool overhang length must be as short as possible to avoid chatter. When the tool overhang length is long, decrease the number of revolutions and feed
The above table shows the conditions for standard shank type cutters. When using long shank type cutters, the number of teeth may be different.
Cutting conditions are generally limited by the rigidity and power of the machine and the rigidity of the workpiece. When setting the conditions, start from half of the values of the standard cutting conditions and then increase the value gradually while making sure the machine is running normally

The above table shows the conditions for standard shank type cutters. When using long shank type cutters, the number of teeth may be different.
Cutting conditions are generally limited by the rigidity and power of the machine and the rigidity of the workpiece. When setting the conditions, start from half of the values of the standard cutting conditions and then increase the value gradually while making sure the machine is running normally
