Failure to observe the precautions maycause serious damage to human body. Revolution(min-1) Balance quality grade GISO 1940-1/8821(JIS B0905) Warning about Max. Revolution indicated on main body ~20,000 G16 1. Do not use the end mill or cutter at the maximum revolution or higher since the centrifugal force may cause inserts and parts to scatter or the body may be damaged even under no load. ~30,000 G6.3 2. For actual practical revolution, please set within recommended cutting condition. 3. When using at a higher revolution (over 10,000min-1), refer to the table to adjust the balance of MEC and suitable arbor. 30,000~ G2.5 M57 Milling
