slant bed CNC lathe


Phil Plumbo
 

From: Dan Falck <dfalck@...>
South Bend model A 9" lathe. I have a full cross slide from a giant
LeBlond that I want to set up just behind the bed of the South Bend, at an
angle, to make a slant bed CNC lathe. It would be possible to leave the
manual aspect of the lathe alone that way.
Dan, this sounds interesting but I can't visualize it. Could you please
elaborate on this?

Phil,
I have this huge cross slide that has about 10" of travel, with a compound
that has 3" of travel. If the 10" long dovetail slide was mounted parallel
to the South Bend's ways, at an angle that still permits a toolpost mounted
on it to reach- it could be a second bed on the lathe. This might seem a
little far fetched, but it looks like it would permit both manual and cnc
control.
I am sorry that my explanation is murky. When I make a drawing, I will post
it in the dropbox.
A quick and dirty way of making a cnc lathe with a South Bend is to mount a
Sherline XY table on the ways.

Here in the UK they made a full size CNC add on for lathes called an Audit
attachment. It bolts onto the bed by a subplate and has a 8 tool vertical
turret. Layout is just as described above.
I bought on the other day with a Fanuc OT controller on it, all working etc.
I may put this on a big centre lathe I have or resell it on. It's too good to
see it go for scrap
