Hey everyone, first post here.
First mill I used was a Lguan FTV-1, and a couple of Bridgeports, then I got to use my buddies old Tree 2UVR.
So, after much reading, and reading, and re-reading, I found on Craigslist a Tree 2UVRC - Journeyman / Tradesman 200. It was part of a giant lot of gear to sell. I asked the guy if they would let it go seperately, and they said sure. I asked how much, and they said $600. Yeah....$600.
I went down to the shop which is only 5 miles away to check it out. It has the body of a 2UVR-C all right, big box ways. No powerfeeds at all unfortunately (I guess that was redundant with the servos). The kid who works at the shop and was handling liquidating their equipment said he had never seen it turned on, it just sat in the back of the shop taking up room. They put power to it, and after some fiddling with the enclosure door lock / switch, she turned on. The NC control seems to be shot, no response to any button mashing, but the forward and reverse buttons fired up the motor.
Ahhhh, she purrs like a kitten. No grinding, clunking, nada...just smooth.
I tested the spindle for any runout...I couldn't find any...not anything more than one Thou at least. The quick change collet system worked fine, and they even had 8 collets. Check backlash on the X-axis, there is maybe 1-2 Thou tops.
On the negative side, the motor brake doesn't work (I'm thinking the cork is just worn away).
The Y-Axis is almost impossible to move. It does move, but it is SUPER hard. I'm not sure if the servo motor was fighting me, or it was bound up from sitting for 18 years not being used.
The electronics (at least the NC part, there was no tape reader available) I am figuring are junk. I could hear different relays clicking when manipulating some of the major controls.
There is no X or Y table locks due to the machine being NC.
No powerfeeds at all.
So, I am going to use it in a manual fashion until I get some more coin together and will Linux CNC the beast.
What I am looking for is does anyone have any input or advice upgrading this mill to a newer CNC system? I want to go full 3-Axis, LinuxCNC, etc.
P.S. Does anyone know if AdobeMachine is around? He has a very similar setup and I need to pick his brain.
