(Note 3) Cutting conditions should be adjusted according to the machine and work rigidity. (Note 4) It’s possible to occur vibrations in certain cases. Please reduce depth of cut and / or reduce cutting conditions in following cases: - When using long shank; - When using long tool overhang with arbor type; - When application has poor clamping rigidity or when using a low rigidity machine. (Note 5) If chattering occurs, reduce ap and Vc by 30% and keep the same fz per tooth.
