Re: CNC lathe designs

Carlos,

Depending on the type of work you'll be doing a tailstock may or may
not be needed.

There was a time when large machines that would need a tailstock to
make use of their capacity came with a tailstock which was included
in the base price. Nowadays, it seems the come-on ads for new
machines feature a base price that looks very attractive, then you
read the fine print and see that the tailstock you need will cost
$12,000 more.

Incidently, here's a little fun fact from a long ago article in one
of the industry mags related to high production turning. "98% of all
turned parts are less than 1" in diameter and less than 2" long".
Which could be interpreted to mean relatively few turned parts
require a tailstock.
