Copy Mills • M270™ Series
Additional Application Advice • M270 High-Feed
Applying High-Feed Tools
The high-feed concept bases its strategy in small depth of cut and high fz
values, which results in a higher MRR and productivity with low radial forces.
Recommended when long overhang is
necessary due to lower radial forces.
Maximum L/D ratio of 10 x D.
Ap1 max
Small Ap1 values and higher feed rate
generate lower cutting forces versus
traditional milling strategies.

Rt
For CAM programming, the tools can be
programmed as a toroidal tool type by
using the Rt value as the insert radius.

NOTE: Use two effective teeth for feed calculations.
For materials above 45 HRC, we recommend adjusting the ae max to 55% of cutting diameter and using no more than 50% of Ap1 max.
While centre cutting is possible, we recommend using a ramp angle of 0.5°–1.0° to ensure smooth operation.
