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.

Ap1 max

Small Ap1 values and higher feed rate generate lower cutting forces versus traditional milling strategies.

Recommended when long overhang is necessary due to lower radial forces. Maximum L/D ratio of 10 x D.
