A threaded roll carries a groove that has to repeat at a fixed pitch along the body. This clip shows that grooving pass, with the insert working a long, repeating cut.
What the clip shows
- Repeating groove along the roll body
- CBN insert in a long, interrupted sequence
- Pitch consistency visible across the body
Why this insert suits the cut
A repeating groove gives the insert no rest. Each entry is a small impact, and over a full body those impacts decide insert life more than the cutting speed does.
Where this part is used
Threaded rolls are used in piercing and speciality mills. A pitch that drifts along the body produces out-of-spec product for the whole campaign.
What to send with an inquiry
- Pitch, groove count and body length
- Whether the groove is cut in one pass
- Insert life currently achieved per body
