If the machine capacity is not enough for high RPM& Feed, please reduce them same rate.
When you attach Endmill, keep vabration of botton of cutting-edge under 0.01mm.
If the rigidity of the machine or the work materials installation is very low, or chattering and noise are generated, reduce the revolution and
feed rate proportionately.
