For Lighter Radial
Depths of Cut - Higher range of Recommended surface Speeds
should be used.
For Greater Radial Depths of Cut
- Lower range of Recommended surface Speeds should be
used.
For Slotting Applications - Speeds should
be Reduced Approximately 20% of lowest Range Value.
Axial
Depth of Cut - Recommendations Are Not To Exceed 1-1/2
times the Cutter Diameter.
Please Note: The above
recommendations should be considered only as a starting point,
with possible variations to achieve optimum results.
