A single wiper insert mounted on the HOF D..R07 cutter does the required job. The wiper insert
protrudes less than 0.1 mm axially. Wiper inserts have only 4 cutting edges. There are 4 marks
engraved on the wiper inserts. Pay attention when mounting the insert in the pocket that the marked
cutting edges are parallel to the bottom of the cutter (see sketch).
Maximum depth of cut when using the wiper insert is 2.5 mm. It is recommended to use wiper
inserts in ap=0.5-1.0 mm to achieve the best results. The criterion for indexing the wiper insert
should be the decreased quallity of the surface finish.
Recommended machining conditions for finishing operations:
Vc (finishing)= Vc (roughing) x 1.25 m/min fz=0.10-0.15 mm/t
