- The width of the parallel land (F) of the insert is 1mm.

9Nodular Cast iron160-250115 (140) 180--0,14 (0,25) 0,4- Width a cutter of 10 inserts and using a feed per tooth (fz) of 0,3mm, the feed per revolution (fn) will be 3mm, i.e. 66% bigger than the parallel land.
S11Heat Resistant Super Alloys200-320--20 (40) 550,1 (0,15) 0,17- To obtain a good surface finishing, the feed per revolution should be a maximum of 80% of 1mm = 0,8mm.

(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: - Result: Feed per revolution (fn) could be increased from 0,8mm to 60% of 6,0mm = 3,6mm. - When using long shank; Note: Other limitations, such as machine power, must be taken into consideration. - When using long tool overhang with arbor type; - 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. Vc (m/min) - The points and the letter (R or L) on the insert indicates the side that should be parallel to the worspace material. Feed fz (mm/t)
