| 9 | Nodular Cast iron | 160-250 | 115 (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. | |
| S 11 | Heat Resistant Super Alloys | 200-320 | - | - | 20 (40) 55 | 0,1 (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. | ||||||
