Sintered parts are porous, and porosity changes how a cutting edge behaves. This clip shows a CBN insert turning a powder-metallurgy component.
What the clip shows
- Sintered workpiece with residual porosity
- CBN insert in a light, controlled cut
- Edge condition after cutting an abrasive structure
Why this insert suits the cut
Porosity interrupts the cut at a microscopic level and the material can be abrasive. A sharp, wear-resistant edge keeps the surface closed instead of smearing it.
Where this part is used
Powder-metallurgy parts appear in automotive transmissions, pumps and small mechanisms. They are usually finished after sintering, with little stock to remove.
What to send with an inquiry
- Sintered density and alloy system
- Stock allowance after sintering
- Whether the part is sized or machined after
