- To obtain a good surface finish, the feed per revolution should be a maximum of 80% of 1,8mm = 1,44mm. - The wiper insert will have a parallel land (Fw) with a width of approximately 5,5mm. - Result: Feed per revolution (fn) could be increased from 0,8mm to 60% of 5,5mm = 3,3mm. Note: Other limitations, such as machine power, must be taken into consideration.

(Note 1) Cutting conditions ae/Dc=70%. (Note 2) 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.
