Agreed - wanted to make sure you were aware of the set up tho.I think it is best to keep the lathe and mill hardware separate. I see no need for 3 phase power at the mill.
Noted. Ok.I thought about it for a bit and see no advantage in replacing the servo drives, the original drives will work fine and the foot print of more modern drives is not substantially smaller than the original drives. The power supplies in the upper box are pretty much useless, so replacing those will be needed. We only need to modify the rectifier section on the servo drive frame to accept a single phase input, and provide a proper transformer to feed it.
Ok - Will go ahead and pull the trigger on the 115 volt config. Simplifies in some ways. The original switch is a little ratty - but I think I can clean it up. The wires coming out of the back look decidedly un 115V though. Will I be able to utilize this switch and just rewire? Perfect place on side of mill head with indentation I have spotted for it. Could make a custom aluminum block to mount with.115VAC solenoid valves are fine. No problem with using 115VAC for the control power on the whole machine. There is already a transformer in the control enclosure for the 115VAC supply.
Let's assume large box will be utilized.I'm not sure if the control enclosure size can be reduced. There is just a certain amount of stuff that needs to go in there and you really don't want it too crowded.
When I have all the components there, I'm sure I'll have a better appreciation for that space.
Not at all, it might work. Most of the barrel blanks I work with are 1.25" That would be tight to get it through without damaging the barrel finish but I can work around that. Would have to create a spider that would attach to the back of the spindle to center up the barrel on that end, that might be a bigger challenge. I guess I need to check one out in person to be sure.
Thanks very much for your help.
Would like to strip out the components we won't use in long term, and all the old wiring, when we make these changes.
Nice to work in a clean space - no point in having boat anchors filling it up.
Yup - good rundown.Current needs:
- Get the axis motors under better manual control
- Get the power drawbar working
- Reduce the footprint of the control enclosure
After you have a think - let me know what you feel the config will be - and what I will need to source.
Thanks!
