Newbie needing info!
« on: December 22, 2009, 04:35:22 PM »
Hello all! I just bought a CNC Router form a sign company they never used. This was due to them not knowing how to run it and not wanting to learn the software. So I picked it up and was doing some basic cleaning and piddling, and found some slop in the Z-Axis. The router is held by two 1/2" bars with 4 linear bearings. The bearings are Thompson Super 8's, inserted in what looks to be a PVC material bearing holder. The bearing rests inside the holders with snap clips, and the holder has 3 machine screws attaching to the plates. What I found was, the Super 8's have these 4 steel pieces that have worn out the PVC holder, causing the slop. All I know about the CNC Router it was bought in 2002, the motors are made in Italy, 8 wires, going into 4. Has one limit switch per axis, table is approx. 30" x 50". The breakout board was made from a company that is out of business. The CNC works, but my question is, can anyone tell me what kind of CNC I have? There are no marks. brands, plates etc. None on the power supply box, or the breakout box. The reason is I want to get some new bearing holders, but need to know what to look for. Or should I just get someone to turn 4 new ones from aluminum? I can add pictures, just let me know what to take the picture of and I will add...

 Thanks so much in advance!

I think these are what your referring to. Might try ebay if cost is a concern.

Yes, those are the bearings. What I need is the holder those bearings slide into. Here is some pics. The holders are blue in color, the bearing is black. I need the blue part...

If I were going to get some made, I would go for the aluminum at the very least. That whole stage part should have been made from a billet, but it looks like cost/time was a factor. If your not careful, machines are easy to sink a ton of money into. This one looks like a superb candidate to learn on. My personal advise would be to replace the parts in as much of a cost effective manner as possible.

Yes, I thought aluminum would be the best route. Here are some pics of the breakout box:
