Rebar rolls are cut with a groove pattern that wears with every tonne rolled. This clip shows rough machining on a rebar mill roll body before the grooves are cut.
What the clip shows
- Rough pass on a rebar mill roll
- Hardened surface, continuous cut
- Body prepared for groove machining
Why this insert suits the cut
Rebar rolls are replaced or re-cut often, so the roughing pass has to be fast without burning the insert. CBN handles the hardened surface; the groove work that follows is where the profile is set.
Where this part is used
Rebar mills re-cut rolls on a rolling schedule. Every hour the roll is out of the line costs production, which is why roughing is measured in minutes.
What to send with an inquiry
- Roll drawing with groove profile
- Hardness and depth of the worn layer
- How often the roll is re-cut
