For materials in other groups, the cutting depth should be adjusted using the reference ratio shown in the above table. The above conditions are reference conditions for finish machining. For rough machining, it is possible to increase the feed rate by around 30%.①Use the appropriate coolant for the work material and machining shape.②These Recommended Cutting Conditions indicate only the rule of a thumb for the cutting conditions. In actual machining, the condition should be adjusted according to the machining shape, purpose and the machine type. ③If the machine rotation speed is insufficient, reduce the rotation speed and feed rate by the same ratio.Work materialsdepth of Cutlength(mm)122030401220304020402040204020402040305472305472305472305472(mm)(mm)(mm)0.170.130.10.080.240.20.170.10.070.0350.150.080.210.10.280.140.350.180.150.10.070.250.180.10.350.250.150.550.40.22CopperHardened steelsHardened steels139
