The cut here runs along the outer diameter of a mill roll, which is where most of the stock removal happens. The clip shows the insert travelling the body with the load spread across the edge.
What the clip shows
- Outer-diameter turning along the roll body
- CBN insert, single pass, steady load
- Roll ends left with enough stock for the finish pass
Why this insert suits the cut
Outer-diameter turning on a hardened roll is a balancing act: take too little and the insert rubs, take too much and the roll deflects. A CBN grade with a strong edge holds the middle of that window.
Where this part is used
The outer diameter of a mill roll is the surface that contacts the strip or the product. Recovering that diameter is what puts a worn roll back into service.
What to send with an inquiry
- Finished diameter and the stock available to reach it
- Tailstock support and centre condition
- Coolant or dry cutting preference
