REGULAR MILLING (Low-speed,high-feed milling)
Caution:
Sparks generated during operation or heat caused by tool breakage can cause fire, be sure to use
all proper fire-prevention measures.
* The conditions below are for high speed/high precision machining centers.

1. Use a rigid and precise machine and holder.
2. These milling conditions are based on milling with circular interpolation at corners. For milling
without circular interpolation (such as right angle corners),reduce the speed to 50-70% and the
cutting depth to 50-80% of the above conditions.
3. We recommend using dry air blow or MQL(mist).
4. Please adjust the speed, feed and cutting depth according to actual cutting conditions.
5. When UOR enters in Z axis, reduce the feed speed to 30-60% of the above conditions with
machining incline angle(β)≦2∘
6. These milling conditions are for a tool extension length:less than 4xD. For a longer tool
extension, reduce the speed, feed rate, and the cutting depth in accordance with the respective
coefficients, to prevent chattering.

Ultra-high speed conditions
When milling flat areas with a stable load, the speed and the feed rate of the high-speed conditions
can be fruther increased to 150-200%. The ultra-high speed conditions are for a tool extension
length:less than 4*D. If the tool extension length is over 4D, do not refer to it.
