Thank you very much for helping me.

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...

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...

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.

I used CNC lathe insert is CBN Sphere diameter is 38.1 [+-0.03mm], inside 30[-0.008 +0.03] RPM from 150 and feedrate 0.15

Thank you for your attention; this is the chip and program I used for machining.

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...
