Customer benefits
○ Machining time reduced by approx. 1/3
○ Increased feed rate
Result
Increased process security thanks to reduced wear.
In addition the customer can maintain process security while
increasing the feed rate and thus also the metal removal rate
from 955.5 cm 3 /min to 1,365 cm 3 /min.
○ Swarf control
○ Reduced wear
