Eagle Mill drill conversion

[George]

[IMG]eagle25[/IMG] Looks like my Eagle 25 is very similar to the Grizzly I have seen in these forums. Looks like I also got a long way to go but I'm willing to have a crack at it.

First step is the servos's
How about
Vexta, 5.4v 0.68 A/phase 118OZ-in 83.2N-cm 3.6ohms per winding 6.5mh/phase/winding rotor inertia 1.09 OZ-ins2 200g-cm2. Are these mane enough for the job ? Cant see RPM quoted anywhere. Also I see lots of sevo's at 40volts or 50volts etc, the Vexta's are only 5.4volst, is this a problem ?

What cost encoders and where to buy ?

Should I fit ball screws, what cost and where ?

Thats probably enough questions for now, any help would be very much appreciated.

Many thanks

George

Are you sure those are servos and not steppers? If they are steppers (I think they are) then no, they won't be big enough for a mill drill.
