back knife lathe (mistake correction)

Hi all!

I went to double check my post (had a gut feeling) and found that I
had confused two hi-production lathes used in furniture factories.
The link below will detail the differences and correct the
misinformation I posted. I've snipped the pertinent bits for those
who don't need/want the details...

The second link below has a pic of the knife assembly I described.

Sorry for the mixup.

The very high production machines include the Back Knife Lathe and
the Rotary Lathe. Back Knife Lathes use a Guillotine type of knife
with the profile ground into the face of it.

The Rotary Lathes use a cutterhead with multiple knives of
alternating shear. The cutterheads are expensive however when used
on repetitive runs of moderate size the price becomes only pennies
and the quality is superb.
The length of the arbor determines the amount of tooling length and
thus the amount of wood that can be turned in one pass.

Older automatic machines were designed with air or hydraulic rams and
hydro-check systems for controlling the carriage movements. Newer
machines use ball screws and servomotors with controllers.
