I think the one I saw was on a Miyano lathe. I just tried to find it but couldn't.

Either way the basics are now understood and adjustments were made. OP looks like hes got better results...

I am glad to see the improvements. Another way I have seen is the parting tool stopping before center and an air actuator that "punches" at the material left over to break the part off.

I put a...

Yes. The HSS tooling can take some chatter and vibrations a lot easier. When HSS tools chip, they are easier to re grind and sharpen the cutting edge. They are also a lot cheaper.

I have great...

This is the information I was hoping would show up here. I have no swiss experience but I see cnc lathes with constant SFM to keep the carbide cutting at the smaller diameters.

This is the main...

I am not sure how to bring one on center on a swiss machine. I have mine on cross slides or a vertical slide. I can bring them in by hand and line it up with the face of the part by eye. Making sure...

I run screw machines with HSS cutoff tooling. I dont use carbide unless it is a ring or the tool doesnt have to go below .250: due to chipping the carbide.

If I have anything difficult to machine...
