NOTES: Down milling CNC programming is required. “ae” value max 0.2xD - “T” value max 0.1xD. The use of end mill with diameter 30-40% smaller than the width of the slot is recommended. The cutting conditions are based on CNC programming with medium dynamic speed.
| With lower CNC dynamic speed, use the same cutting conditions or reduce the cutting speed Vc. | HSS | |
| With higher CNC dynamic speed, reduce the “T” value by approximately -30 -50% and apply the maximum available cutting speed Vc. | DRILLS | |
