Product Detail
PCD Ball Nose End Mill
PCD ball for aluminum freeform tip-glaze failures that leave facet steps—abrasion-evidence RFQ.
Failure-mode lane · Al tip glaze
Facet steps after aluminum freeform tips glaze
High-silicon aluminum freeforms show stair-steps when the carbide sphere tip polishes flat. This page opens on that tip-glaze failure and the PCD spherical contact that restores blend continuity—not on steel scallop CAM math.
Glaze / facet failure checklist
- Shine and flats on the tip under a loupe
- Blend radii into sealing faces show visible steps
- Al-Si lots chew tips before the planned tool change
- Operators keep shortening step-over to hide facets—still fail Ra
Evidence packet (abrasion first)
- Alloy / Si note from the print or melt cert
- Tip wear photo from the carbide incumbent
- Ball radius taken from the freeform model
- Scallop or Ra if called—secondary to abrasion proof
- Holder / runout on the finish spindle
Disambiguation

PCD tip-failure FAQ
Square Al pockets?
PCD square owns prismatic walls; this URL is spherical freeform tip life.
Stock PCD ball kits?
Quoted from the freeform print and wear evidence—not a shelf assortment.
Same as carbide ball?
No. Carbide ball opens on ferrous scallop geometry; this opens on Al tip glaze.
Tip wear evidence ready?
PCD ball quotes lean on abrasion evidence plus radius callouts—failure mode first.
