Grooving is the narrowest cut in roll machining and the one that punishes the insert most. This clip shows a groove being cut into a profile mill roll.
What the clip shows
- Narrow groove, side load on the insert
- CBN edge held in a confined cut
- Chip clearance inside the groove
Why this insert suits the cut
In a groove the insert is surrounded by the work. Chips have nowhere to go, heat stays in the cut, and any deflection shows as a tapered groove. Edge strength and chip control matter more here than in open turning.
Where this part is used
Grooved rolls form rebar, wire rod and speciality sections. Groove geometry decides the finished profile, so the cut cannot be patched later.
What to send with an inquiry
- Groove width, depth and root radius
- Whether the groove is cut in one plunge or stepped
- Chip evacuation and coolant access
