Any lathe tool changer plans around?

Mcgyver, I think in a way your misunderstanding where I am going with this, the rotary table would be in verticle position for one, I got my rotary table spinning over 10rpm(thats only at 25000hz) and it 'seems' rigid, but I have yet to try it.

I belive that the enco compact lathes use a rotary table type thing with a locking pin(not totally sure on the locking pin)

Heres the service manual I picked up somewhere(not sure, maybe mach2 group or mini lathe group)

ahhh, you are right i was thinking something completely different. I took turret to mean the turret in a quick change tool post.

funny how a little thing like what plane we're talking about can send a guy completely down the wrong path

Ozzie, you beauty!
I have traced the files on the site back to this website with pictures and movies!

This one seems like a keeper to me. I am off to do some more reading on it.
Thanks!

i also have a dorian tool changer nice bit of kit
the locking mech is a pneumatic wedge ( imagine a gear wheel and using a key to lock it in position)

Hello,

Someone posted an exploded view of the Emco Maier turret. This turret works okay, but you need to be aware of it's primary weakness if you exploit the design.

You will see a thin metal strip that goes under the center shaft, this device works like a ratchet and pawl and serves the purpose of a "shot pin" to lock the turret in position. The worm gear rotates the turret past the drop in point, then backs up against the metal strip to lock it.

This metal strip will bend and flex under moderate loads allowing the turret to rotate (tool goes down below center). If you do anything with the design, this is the area that needs some serious attention - beef it up in some fashion to prevent this problem.

Other than that, the turret performs pretty good. We had three lathes in a CNC training lab that saw constant use over a 5 year period. Other than that problem, it works well. We could not cut steel on the machines with any reliability, however, aluminum and other light allows worked well.
