For Maximum Productivity
  • A continuous cut is recommended. An interrupted cut may cause chipping or breakage.
  • When using a Hydraulic or Shrink chuck, blow air to the arbor body, DON'T blow air to the endmill itself.
  • A Minimum speed of 980 SFM 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.
When cutting HRSA materials
  • Continue to machine even if you see BUE, removing BUE may cause chipping or breakage to the edge.
  • High speed machining work hardens the material. For this reason, leave at least 0.3mm of material for a finishing process.
