Has anyone ever encountered a problem which Centerless workpiece profile are concave only on a specific diameter?
My material is SUS306 with diameter of 0.330mm, I tried to Grind it down to 0.064 in tapered shape but somehow concave occurred on my tapered part just only at the diameter around 0.27-0.30 as in the attached pictureView attachment 291997, but on the different diameter even though it is tapered shape none concave occurred. I tried changing the alignment and such but it doesn't seems to help does anyone know what might cause this i'm kinda desperate now.
