I remember a conversation with someone, I think it was "manike", he said any it was possible to convert any 3 axis mill to 4 axis. Can someone explain how to do it. It seems to me that you would simply buy an attachment to bolt to the table, but that's just a guess.

What exactly is the difference between 3 and 4?

i believe the bed can rotate... but as I'm a milling newb, it might depend on the machine.

I'm pretty sure Fred is correct. You can drop a horiz/vert. rotary table on any standard mill. Fix your workpiece to it and you've got yourself a 4th axis.

Ahhh, I see. I didn't know that was a 4th axis.

Yes, I do have a Rotary table, I suppose that would be a 4th axis, but not the answer I was looking for.
If I remember correctly, the way manike explained it was something like this "extend your arm out as if you were pointing at some one, now rotate your hand in a circle, that is your 4 axis". Was he referring to the rotary table used in the vertical mount?

Luke,
That can be mounted horiz. or vertically depending on your needs.Comment

"That can be mounted horiz. or vertically depending on your needs."
Yes sir, MOST can, mine does. But, is that considered the "standard" 4th axis?
I guess any "movement" other than xyz would be considered a 4 axis.
How about this, if I were to buy a 4 axis mill, what would the 4th axis be... 1. left-right, 2. fore ward-back, 3. up-down, and 4. (?)Comment
-
Yeah, I believe the "standard" fourth axis is "turning" on a mill. But as you said, any movement added to xyz would be the fourth axis.
All machines that I've seen advertised as 4 axis have had the rotary table as the 4th.Comment
-
Yes the 4th would be a clockwise/counterclockwise turning to make more complex shapes.I think there for, I am I think. am I?Comment
-
That's interesting, I would have thought that the "standard" 4th axis would have been a tilt table of sorts, because with CNC you can cut a curve by controlling the x&y axis....
Big'n slo where did you find the that table? I'm still looking for places to by tooling and accessories....Comment
-
still at it I see
yes what big'n slo showed you is indeed a "4th axis"
you would install the rotary table in the horizantal position.
The table can be had with a tailstock as well
so that you can hold a longer part between centers.
If you are working on round parts a lathe chuck can be
mounted to the face of the table.
as to where to buy why not back to grizzly

Hey Steve,
Yea I'm still at it! (every day)
Is there such a thing as a powered tilt table for CNC? I'm trying to figure out how cut an angle on the top of a work peace with CNC. The head on my mill tilts, but I wouldn't think you could control that with CNC... (?)
BTW, I have a 10" rotary table (manual).....

the simplist way is to bolt an angle plate to the rotary
table. thats the most common way that I have seen
the really expensive way is like this http://www.tsudakoma.co.jp/mta/english/index.html
(third table down)
I'm having a hard time with the internet today most of my
posts are not making it

GRRRRR. So I should have bought the rotary table with the angle plate right out of the gate....
