High-chrome cast iron is abrasive and hard, which is exactly why it is used for wear parts. This clip shows a CBN insert cutting it in a stable heavy pass.
What the clip shows
- High-chrome cast iron workpiece
- CBN insert under continuous load
- Surface and chip behaviour in an abrasive material
Why this insert suits the cut
The chrome carbides that give the material its wear resistance also attack the cutting edge. Carbide wears fast; CBN survives long enough to make the operation economical.
Where this part is used
High-chrome iron is used for slurry pump parts, mill liners and crusher wear plates. Machining is the last step before the part goes into service.
What to send with an inquiry
- Chrome content and hardness
- Casting skin condition and stock allowance
- Whether the part is machined before or after hardening
