Hello, 1st post from a self taught CNC Lathe operator...
I run a Haas SL30 Lathe, I need to turn a bunch of patterns from 18" D2 steel(4" thick) and it is taking me so long it is TORTURE...
Since I am self taught I never really learned how fast to turn parts or how hard I can run my machine.
I have my RPM(CSS) set at 415 and a max spindle RPM of 600. This is where im unsure because my chuck is only 12" so I need to use a jig plate to hold large parts and I am afraid if I turn at high RPMs that the part may come loose.
I currently have my depth of cut at .05 and my feed set at .01 IPR. I use CNMG 432 inserts. I usually have to change my insert every hour or so, is that too long?
I work in a job shop that does all prototype work, no production.
Please give me some tips
