Need maintence manuals for a Tree Vertical Mill Journeyman 300

I just received the CNC Tree mill that I bought for $750 on ebay. It waa
sold as is and stated that there was missing parts in the CNC portion. It
had no bids after three days and a low buy it now price. Since I had
previously retrofuitted and Tree mill similar to this one I jumped at it
because those are really good heavy iron and quite ridig machines. The
machine that I retrofitted was about 5 year older than the Jouneyman 300.
But there was only .0005 backlash in the XY axis. The ways were perfect so I
figured this one with the bijur oiling system would be the same.
The machine arrived yesterday and with some friends on mine we off loaded
the machine and moved it into my shop with few problems. Later, I'll put
tgether a list of tips for buying a machine on ebay and having it
transsported across country.
What surprised me so far is that despite the 1/4" of goop on the table, it
was pristine under the goop. Not a single gouge or mark other than some
stainning which looks like it will polish clean.
The X axis has .0015 backlash and the Y axis has about .050 but I see what
the problem is. The Y axis must have run into a stop and the ball nut came
loose from it locking key. Looks like an easy fix.
The knee is different dfrom the one I retorfitted. The retrofitted one used
a servo motor on a gearhead drive to raise and lower the knee. Mine is
manual.
The Quill on the Journeyman 300 is servo driven. When I manual rotate the
belt drive it seems to have zero backlash but its hard to reach and an move
the belt and watch the dial indicator. It was set up for kwick switch 30
tooling.
The real surpise was the spindle motor is a dc variable controlled motor.
It looks like the CRT and the Computer portion of the machine is missing
which is fine with me.
It does have the spindle motor control and XYZ servo amp boards in place. I
did get a little bit of information with it about the servo amps and the dc
servo motors and tach's. Since they look like they are a typical analog
servo amp with +/-15 VDc input I may reuse them But one of the main reasons
I bought the machine was because I needed a larger, more rigid machine than
my enco 8X36 retofitted knee mill. I also wanted to build a new servo system
using the newly designed awesome servos from www.cnctecknix.com
They will run dc brush time motors up to 200V at 40A peak as I recall and
the XY motors on the tree mill are 140VDC as I recall.
Since the mill has all the servo motors and servo amps I'll shortly decide
if I will reuse the existing amps or ripout all the large boards and go with
the new.
In the meantime I need the maitenance manual to aid in the few repairs it
looks like I need to make. If anybody has a set of manuals, I would gladly
pay for having a copy made. Please contact me off line.
