This clip is close on the insert itself. Nine seconds of a CBN edge working a hardened roll, with the tool holder, the seat and the contact line all in frame.
What the clip shows
- CBN insert seated in the holder, cutting a roll body
- Edge contact visible along the depth of cut
- Chip forms clear of the finished surface
Why this insert suits the cut
How an insert sits in its seat matters as much as the grade. A poor seat lets the insert move under load, and on a hardened roll that shows up as chipping rather than wear.
Where this part is used
Roll turning is one of the few operations where the insert is changed without stopping the machine for long. Getting the seat right keeps that change quick.
