Recommended cutting conditions [Note] CD Use a highly rigid and accurate machine as possible. CD These conditions are for general guidance; in actual machining conditions adjust the parameters according to your actual machine and work-piece conditions. CD If the rpm available is lower than that recommended please reduce the feed rate to the same ratio. CD To increase efficiency even further, increase the rotation speed and the feed rate by the same ratio.
