■ NOTE
1) The cutting parameters to be adjusted according to the machine rigidity or work rigidity.
2) In case chatter occurrs, recommend to reduce depth of cut or spindle speed with keeping feed per tooth.
3) If machine does not have enough power, recommend to reduce depth of cut first and reduce spindle speed and
feed speed.
4) Use air blow to flush the chips out. B039
