    Milling Hardened Material

    Thanks for all the help. Sadly grinding would be absolutely impossible for the type of work. Recommended speeds for the YG1 Powercut mills are around 12000 RPM fed at 40 inches a minute. So I think I will move from that to a cbn endmill. I am hoping the cbn will run close to those parameters...

    Milling Hardened Material

    Hello, I am looking for some feeds and speeds to mill 6150 material that has been hardened to 60 R "c" on a Yasda high speed jig borer. We are using a 6mm 4 fluted carbide end mill that is coated. I can not find any feeds for materials this hard. Thank you Bud
