My first post and rather a difficult one to address. I was advised by a good mate to come here, as he said, if the answer is out there, this forum will have it.
The issue I am trying to solve is turning 304 stainless bar on a Puma 2600Y slant bed CNC. The job requires parallel turning 300mm long * 14mm diameter and so far its been a pain in the butt. I have managed to reduce most of the vibration, but not enough as I still need to put the job in a manual lathe to polish it satisfactorily enough for delivery to the customer.
Being a slant bed, there is no steady rest available for it. Currently I'm running a WNMG with a 0.8 nose radius as the roughing tool at 160mpm and a clamped spindle speed of 750. Finishing is with a DNMG 0.4 nose radius at 180mpm and a clamped spindle speed of 500
