  • A continuous cut is recommended. An interrupted cut may cause chipping or breakage.
  • Continue to machine even if you see BUE, removing BUE may cause chipping or breakage to the edge.
  • A Minimum speed of 300m/min 980SFM is required. (Don’t run at lower speed)
  • A 1.5 degree ramping angle is recommended. Run at 50% lower feed rate when ramping cut.
