I bought motion control gear and wanted some mini sliders. I picked them up, they MIGHT be useful to you, but it all depends on how specific you want it to be. I would stay away from CNC work. I use them as macro focus guides and it jiggles quite a bit as they move across the track. It would probably be fine for the Z axis of a CNC plasma, but if you hook one of these up to your CNC router it's going to stick and break. bits. For my use they are tolerable.
