    Machining does not achieve a surface roughness of Ra 0.1

    Thank you very much! Thanks to your advice, it seems I can address the issue after nitriding. However, I still have a problem achieving a profile tolerance of 0.05 after heat treatment. Could you review my program and the type of tool I am using and give me your opinion? I suspect that my...

    Machining does not achieve a surface roughness of Ra 0.1

    Thank you very much for the information you shared. However, even right after heat treatment, achieving a surface finish with a roughness of Ra 0.1 and a geometric profile tolerance of 0.05 was already very challenging. After nitriding, it has caused uneven dimensions on the product. Regarding...

    Machining does not achieve a surface roughness of Ra 0.1

    I tried increasing or decreasing the spindle speed and feed rate, but the result was that my chips became chipped. This product has undergone nitriding.

    Machining does not achieve a surface roughness of Ra 0.1

    I'm looking for a way to machine a spherical product made of SUS304, with a required hardness of 60 HRC after heat treatment. I've selected a specialized turning tool designed for machining hard metals, but I still can't achieve a profile tolerance of 0.05 and a surface roughness of 0.1. Can...
