Been some time...
Long update here - and a question at the very end.
I am moved into my shop - and have put in a huge effort to organize and set up.
Not complete - but pretty close and feels great to have the space.
Short video here if you want a laugh.
Not going to win any directing awards...
I'm getting 215V single phase from my "209V 3phase" breaker box.
As had been suggested by others - the VFD (who's documents said it would be fine) is in fact fine.
The machine is alive!
My 10EE lathe is suffering a self inflicted electrical issue - and I spent a lot of time this month learning about how to fix it.
Rebuilding SCR's and testing control board.
Sent control board out to have it checked by the original manufacturer.
Great warm up project before tackling the 5BVK CNC project.
With some time finally to focus on the mill - the first thing I tackled was the central oiling system.
The system is gummed up and the motor doesn't work.
Its been okay hand oiling while I used it as a manual mill - but I don't want to run it CNC without being sure everything is well lubricated.
Started by tearing down the central pump reservoir and cleaning some nasty ancient oil out.
Results below - not very pretty. - but the reservoir has been cleaned and fresh way oil has been filled.
I put power to the motor - but jumping the two wires to the two hot legs coming in to the machine - but it didn't turn.
I was able to just pull the priming handle though - and it pumped nicely.
After some flushing and compressed air, all of the oil ports on the X/Y/Z axis are flowing nicely.
The line that fed the head - and its distribution block - had been disconnected - so I dug in to that.
There is good access in the head casing at the top here
And I was able to get my hands inside the head casting and remove the distribution block for cleaning and inspection.
I found that the block has some metering fittings with check valves. After some cleaning in the ultrasonic cleaner - I was able to get them operating again. However - I noted that 2 were marked with a 3, and one was marked with a 00.
CPV 3
CPB 3
PSS 00
The 00 did not want to flow anything.
I also noted that the 00 was a different brand - and wonder if it was original or a "replaced in the moment" option.
I used a needle drill to boar slightly larger passages - and managed to get some flow - but I plan to replace it. Does anyone know the original specs for these 3 metering pieces?
I did have one weird surprise. I found a thin wire inside the feed tube to this upper block.
It had a green section and a white section and was about 3' long.
The green section had texture.
I suspect someone was cleaning out the line with it at some point - and lost it in there.
Here you can see the white section poking out!
While working on getting the quill and spindle feeds going - I noticed a plug I hadn't seen before.
Its at the front - and looks like an oiling hole access point?
And here is a close up inside the hole the plug is in. Is that a check valve maybe? Is this a second place that the central oil can be fed into?
The oil system is now working very nicely - tho it would be nice to get etc pump motor working/replaced.
Many of the lines are in mediocre shape - and I would like to replace.
Found the OD to be about 4mm on the metal lines.
The nuts on the end are either 8mm or 10.5mm (not a typo...)
So maybe they are even a SAE size?!
Can anyone shed some light on what size lines I likely have?
Thanks!
