Notes:

  • Cutting speeds shown in the left table are of the most outer diameter of the tool.
  • When the depth of cut is the upper limit shown in the above fi gures, set the cutting conditions to the lowest values shown left.
  • When using long edge types (MSE), set the cutting speed and feed to 60 to 80 % of values shown in the table.
  • When using long shank types (LSE), set the cutting speed and feed to 20 to 50 % of values shown in the table, bearing in mind the overhang length.

Notes:

  • Cutting speeds shown in the left table are of the most outer diameter of the tool.
  • The values of the cutting speeds and feeds shown in the table are of under general cutting conditions. The values should be modifi ed depending on the power and rigidity of the machine to be used, and work holding conditions.
  • When using the long shank type, the depth of cut, pick feed, cutting speed, and table feed should be reduced to 70 %-90 % of the values shown in the tables. Machining types
