I have a swivel milling vise. Do I understand it right, as it seems,
that CNC does not care for swiveling and I would be best served taking
the swivel base off?

Usually people go for a rotary table. Then you can "swivel" your work piece
in a controlled repeatable manner. Put a motor on your rotary table and,
"BAM!" 4 axis machining. I can usually clamp most work pieces without one
to get what I want, but it would be nice for a little more consistent tooth
position for cutting some types of gears. If I had a bigger working
envelope I would be really tempted to go 5 axis and put a trunnion table or
a chuck and spindle on top of a rotary table. There are some pockets that
are just a pain to program using just 3 axis.

Thats a personal pref. Swivels dont hurt to have IMO, but a versital
necessity for manuals.
Toolmakers like me use to through them out.
Rotary cross slide- table is the manual equivalant to a 2X CNC.

It is easy to align the vise to the X axis and then you can do anything
with CNC. I found very early that the swivel base gave up a LOT of
rigidity, to the point you could see the vise vibrate on heavy cuts.
Machining went a lot better when I took it off.

well ya............. what are you hogging on a manual thats vibrating
it loose? broken tap E/M :-)
more cutter teeth =3D smoother cut?
5 flt apkt type inserts are key. ie : ingersol- saweet - no coolant
neceassary just a air blast or preferably "cool gun"

Bob, I have a Troyke CNC rotary table (no control, just a servo driven
table). It does not seem to work. I have not even started looking it
it, as I want to work on one project at a time. But I want to fix it
soon, if it is really broken, and use as a 4th axis.

I have the same exact feeling. Thanks

Ditto what Jon said about rigidity. I also like keys on the vise bottom.
Just slide the vise in the slots and its square. Saves a lot of setup time.

Same here. Go into most commercial shops and the vises are all without
the swivels.
Gunner, who has a stack of swivels someplace..but none on his machines.

I generally align the vise jaws to the X axis within .001" I rarely put
the vise body along the X where the keys could fit the slots, as so much
of the time the long edge of the parts is parallel to the jaws. Due to
a small Bridgeport (the oldest round-ram turret millers had a 9" travel
on the Y axis, and do to some goofs in my retrofit, I now have only
about 7.5 inches travel that way). I have a later Bridgeport 12" knee,
but need to come up with a number of parts to retrofit it on my
machine. I wouldn't trust the keys for alignment unless I had tweaked
them myself. The table slots are not precision machined parallel to the
ways, at least on my machine.

There is no practical reason to use the swivel on a cnc mill unless you have it
mounted to
an angle plate to effect an A or B axis.
My Kurt vise sits on top of a Kurt base that Steve Saling, AKA GarlicDude from A.M.C sent me a long time ago. I had to insist on paying for the shipping cost just to feel right about his generosity.
Steve wanted me to tell him when I actually used the swivel feature on my BP. I've used it about 3 times but when I need it, it is priceless. Same for the swivel vise at work.
The joy of CNC is that you don't need a rotary table or a swivel vise to make non-orthagonal cuts.

it mounted to
A.M.C sent
vise at work.
Sounds very nice of Steve and congrats on getting a base. It seems
that all "in the know" agree. I already mounted the vise on the table.

In general -- you are better without it on the CNC machine,
because you can get any angle you want from the g-Codes, and this way
you can be sure that the vise is properly trammed.
If you want a swivel vise -- you want it on a CNC controlled axis on a rotary table. :-)
Enjoy, DoN.

I presume you'll use the RT in a vertical orientation? A horizontal RT
is real handy on a manual mill, but not particularly useful on a CNC
where circular interpolation will do the job.
As for a swivel base on the vise, take it off, it is of no benefit on a CNC mill and only serves to waste an inch of Z height.

Right, the axis of rotation would be parallel to the X axis.
Agree 100%.
