Cutting Conditions- Fw at least 40% larger than fn (fn-f2xZ); PH5705 PH7910 PH7920 PH5740 PHS740 PH7740 - Axial deepth of cut is 0,5 - 0,8mm. 1 Unalloyed Steel 125-220 - 190-280 180-250 - 140-170 140-170 P 2 Low-Alloyed Steel 220-280 - 180-240 170-210 - 130-160 130-160 Example: 3 High-Alloyed Steel 280-380 - 170-220 160-200 - 110-140 110-140 - The width of the parallel land (F) of the insert is 1,8mm 7 Malleable Cast Iron 130-230 190-340 180-320 170-300 170-300 - 130-250 - 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. 40% bigger than the parallel land. K 8 Grey Cast Iron 180-245 180-300 170-280 150-250 150-260 - 110-220 - To obtain a good surface finish, the feed per revolution should be a maximum of 80% of 1,8mm = 1,44mm. 9 Nodular Cast iron 160-250 140-250 100-240 90-210 130-220 - 80-170 - 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 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. The points on the insert indicates the side that should be parallel to Wiper insert with 2 Right-hand cutting edges. the workspace material. The side work of the insert it’s indicated by points.
