1. Cutting conditions shown above are for side milling with L/D ≤ 5xD 2. For side milling with 5xD < L/D ≤ 6xD, reduce Speed and Feed by 10% 3. For side milling with 6xD < L/D ≤ 7xD, reduce Speed & Feed by 20%
4. For side milling with PXMC Extra-Short Collet, increase Speed by 30-40% and Feed by 40-80% 5. For side milling with PXMC Short Collet, increase Speed by 10-20% and Feed by 20-30%

1. Cutting conditions shown above are for slotting with L/D ≤ 5xD. 2. For slotting with 5xD < L/D ≤ 6xD, reduce Speed and Feed by 20%. 3. For slotting with 6xD < L/D ≤ 7xD, reduce Speed & Feed by 35%. 4. For slotting with PXMC Extra-Short Collet, increase Speed by 10-20% and Feed by 10-50%. 5. For slotting with PXMC Short Collet, increase Feed by 15-30%. 6. Slotting with Ø1 1/4” or Ø32mm PXVC is not recommended due to the large number of flutes.
