Notes:

  • Depths of cut (APMX) shown in the table are the allowable maximum values.
  • Mist cooling or air blow is recommended.
  • The maximum number of revolutions of the machine to be used is lower than 50,000 min -1, the revolutions and feed rate should be modifi ed at same rate.
  • Use smallest possible overhang.
