Recommended cutting data (1) For workpiece materials list, see pages 495-524 . As a starting value, the middle of the recommended machining range should be used. Then, according to the wear results, conditions can be changed to optimize performance. The data refers to IC908

  • When using external coolant supply only, reduce cutting speed by 10%
  • Use internal coolant supply when machining austenitic stainless steel
  • When using more than 5XD drill ratio, reduce cutting parameters by 10%
