A profile roll is not a plain cylinder: the body carries a shape that has to be reproduced. This clip shows machining on a profile mill roll, with the insert working a shaped surface.
What the clip shows
- Shaped roll body, not a straight diameter
- CBN insert following the profile
- Interrupted contact as the profile changes
Why this insert suits the cut
Profile turning loads the insert unevenly. The edge meets the work at a changing angle, so a grade that survives a straight pass can chip where the profile steps in.
Where this part is used
Profile rolls form sections in structural and speciality mills. The profile is what the customer buys, so the finishing pass cannot be corrected afterwards.
What to send with an inquiry
- Profile drawing with tolerances
- Whether the profile is cut in one pass or several
- Any steps where the insert tends to chip
