Let's break down that model:
ST=New series of lathe
20=Small lathe series 15" dia x 20.5" length cutting capacity
SS=24 station hybrid turret and faster rapids +1000 RPM +10 hp (decreases cutting dia to 10")
Y=4" of Y travel (+-2") includes live-tooling (decreases cutting dia to 12")
I have attached the data sheet for the ST-20Y/ST-20SSY.
Just a few questions:
Do you currently have any lathes?
What sort of lathe tooling do you have now?
What batch sizes are you going to be doing?
How often are you going to be setting up?
What kind of material are you cutting?
What kind of work do you have for the Y-axis?
