Key Point on Machining
Ni-based alloys that have low thermal conductivity and are prone to work hardening require a
superior coated grade combined with an optimum cutting edge to be machined effectively.
The latest SMART MIRACLE vibration control ball nose end mills have variable pitch geometry
with newly designed cutting edges to reduce vibration.
