Common end mill problems – causes & quick fixes
1. Tool breakage
🔹 Causes: Too deep cut / too fast feed
Material too hard
High spindle runout
✅ Solutions:
Check runout (aim for ≤0.015mm) & adjust parameters
Switch to a tool designed for that material
2. Chipping
🔹 Causes: Excessive depth of cut
Hard material + high runout
High‑speed engraving spindle or old manual machine
✅ Solutions:
Reduce runout & cutting depth – lower parameters
Use a more suitable coating / geometry
