For difficult-to-cut materials (heat-resistant alloys, etc.), the cutting speed DG type chipbreaker is suitable for heavy machines that have low-rpm spindles. should be set 25% below that of carbon steels. If chatter occurs, a lower feed rate is recommended. High speed machining means cutting speeds over 150 m/min. 8-26
