(Note 1) Cutting conditions ae/Dc=70%. - The wiper insert will have a parallel land (Fw) with a width of approximately 6,0mm. (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; - Result: Feed per revolution (fn) could be increased from 0,8mm to 60% of 6,0mm = 3,6mm.Note: Other limitations, such as machine power, must be taken into consideration. - When application has poor clamping rigidity or when using a low rigidity machine. (Note 3) PH5… and PHS… can be used wet or dry. PH7… use only air. How to use a wiper insert: Selection Example: - Since wiper is one corner use to standard cutters, please attach the insert with the parallel land down to the workspace cutting surface.
