Good morning fellow machinists.
I was wondering if anyone could help me. I am struggling with feeds and speeds on smaller diameters.
WHEN MACHINING THE JOB CHATTERS LIKE CRAZY. Length of job is 56mm and a 20mm stock diameter.
I am turning stainless steel 316 down to 8mm Diameter using Iscars f3m range in a maple tech CNC lathe max RPM 4000.
What feeds, speeds and depth of cut should i be using? I am currently running at 110m/min DOC 1.4 F0.18 - 0.22.
When reaching diameters of 12mm and below, the machining process starts squealing terribly. My guess is this happens due to loss of cutting speed.
What should i do !!!?
Any help would be greatly appreciated!
