work material and machining shape.③ The cutting conditions shown in this table are intended as general criteria and should be adjusted according to the cutting shape, purpose, machine used, etc.④ If the rotation speed of the machine is insufficient, reduce the rotation speed and feed rate by the same ratios.⑤ For cutting in, set the ramp introduction angle to 1° and set the feed rate to 60 to 70% of the above values.⑥ In the case of using tools with L/D = 15 or more length from the first process, in order to suppress the chattering vibration of the tools and stabilize the cutting, it is recommended to make suitable guides by using short neck type or ball end mills.プリハードン鋼Pre-hardened steels(35〜45HRC)NAK80 CENA1(45〜55HRC)SKD61 SKT4焼入れ鋼焼入れ鋼(55〜60HRC)SKD11
