This is the same outer-diameter operation as the previous clip, filmed on a different setup. Comparing the two is more useful than watching either alone: the insert is the same, the machine and the support are not.
What the clip shows
- Outer-diameter turning, alternate machine setup
- Same CBN insert family as the first clip
- Different support and centre conditions
Why this insert suits the cut
A hardened roll amplifies whatever the setup gives it. If the tailstock or the steady is not holding, the edge sees an interrupted load and the insert fails before its time. Watching two setups side by side makes that visible.
Where this part is used
Roll shops often run the same roll on more than one machine. Knowing which setup the insert was proven on is part of quoting the job.
What to send with an inquiry
- Which machine the job will run on
- Steady rest or tailstock arrangement
- Whether the roll is turned in place or removed
