IMHO the step/in Rate ist to low and probably the machine not sufficiently rigid.

I do Laser Images on my mill without smoothing faster than 100 ipm and no problems.

Finished part is a spindle for a drilling machine.

All production lathes I have used are:

M10 Clamp
M11 Unclamp

To switch from ID to OD Clamping, or from pull to push chuck there is a parameter or a switch to reverse direction and the sensors on the hollow clamping cylinder have to be adjusted after switching direction.

SSV is a very useful feature for lathes. In this example tool steel with HRC35 turned down from 20 to 18.2mm with 2000rpm f 0.12mm ap 0.2mm on 280mm length with no chatter and less than 0.001mm deviation on a cheap Chinese lathe. SSV +-100 rpm / 1.5s no chatter ok surface finish I am really happy wi...

I hope you are all well in Florida after the storm.
