Turning shallow domes on the ends of 316 SS round stock
I need to turn the ends of between 8 to 12 pieces of 22mm dia 316 SS into a shallow dome, dome radius will be 30mm, dome height is around 4.5mm.
This is purely cosmetic no accuracy required.
The domes need to have a polished finish so I want to turn them as smoothly as possible in the first place.
This will be done on a Hafpos AL340 lathe.
For those with experience in this I guess the questions are.........
The quick option of course is to make a form tool, will that give me a smooth surface or am I going to have serious chatter? I'd be working right at the chuck and I'd step turn the domes in .5mm? steps before using the form tool.
Or should I spend more time upfront and make a quick and dirty 30mm radius turner?
