An interrupted cut is a series of impacts rather than one continuous pass. This clip shows a CBN insert turning cast iron with interruptions in the surface.
What the clip shows
- Interrupted surface: gaps or slots in the workpiece
- Impact load on the CBN edge at each entry
- Edge condition after repeated entries
Why this insert suits the cut
Every interruption is a small impact, and cast iron gives the insert no cushion. Edge preparation and toughness decide whether the insert survives the first minute or the first hour.
Where this part is used
Brake discs with ventilation slots, pump housings with ports and manifolds all present interrupted cuts. It is one of the most common reasons a grade fails in production.
What to send with an inquiry
- Number and width of interruptions
- Whether the gaps are cast or machined
- How the insert fails currently
