Hi everyone, i need some advice from u guys about the Hardened interrupted cut.
We have a problem when we turning and facing the product which has 8 holes on the face, the hardness is about 60HRC. We are using the ceramic insert with data cutting: Vc= 80-120, ap= 0.25 for facing and turning, fr=0.08.
Because of the small tolerance (5-10 mirco) we use coolant when turning (which is not good for hardness turning).
The inserts do ok when they do the continuous cutting, but break when they meet the holes (1-2 passes break)
Do you have any idea about that?
BTW does the data cutting is ok?
Sorry for my bad English...
Thank guys!
