Re: [CAD_CAM_EDM_DRO] X-Y Table, Rotary Table for CNC INFO

Hi Les:
Were you thinking of a four poster bed type of setup with a central
screw?
Or maybe four timed screws with encoders or steppers slaved together?
I suppose you could chain drive them or belt drive them from one stepper
too.
That could work pretty well I think, if you used good hunky frictionless die
bushings and pins.
I'm thinking of the kind that have sleeves with balls in them; the ones
that are used for big punch dies.
You could make the base wide enough that the pins hang over the edges of the
mill table as they come through the base plate.
That way you wouldn't lose too much height under the spindle nose.
Gonna be a pretty heavy accessory unless you make the base out of aluminum.
Cheers

Marcus
