Re: [CAD_CAM_EDM_DRO] Rod required

Hi KK and All:
I believe from my machine designing experience you will find it
best to use two rods spread as far apart as the unit will allow and
then put the screw in the middle between them. This way the torque
and twist from changing direction of the screw movement can best be
controled by the rods.

OK, I have measured the rods I have. Three of them have the carriages
that came out of the donor machines, two of these have a rod diameter
of 0.35 inches [8.89mm] with a length of 15.28125 inches [388.14375
mm], the other is .392 inches [9.9568mm] in diameter, and a length of
17 inches [431.8mm]. The rest have no carriages, I have two at .235
inches [5.969mm] in diameter with a length of 10.5 inches [266.7 mm],
two at .275 inches [6.985mm], one has a length of 16.5 inches [419.1
mm] the other is 9.71875 inches [246.85625mm], and one at .305 inches
[7.747 mm] in diameter with a length of 10.125 inches [257.175mm].
What would my approximate work area be? I plan on using the rods with
the carriages on the X, Y, and Z-axis. Can I get away with just a rod
and lead screw per axis?
