Could some one shed some light on this subject for me please
This is a link to a speed chart for turning (lathe)
,
https://littlemachineshop.com/Reference/CuttingSpeeds.php#Milling
But I am not understanding some thing.
It has 3 inputs. One is the work piece diameter, so that's self-explainatory. But if I type 1.00" work piece diameter and use 1018 plain carbon steel SFM (850) for steel, the rpm comes out to 3250 rpm spindle speed? That can't be right can it?My 1236 lathe doesn't turn anywhere near that fast. What gives? Thanks
