Has anyone motorized a slide like this?

[zephyr9900]

In a box of surplus equipment that I bought, there were two crossed-roller slides like http://www.techno-isel.com/lmc/Produ...dardSlides.htm

Has anyone successfully motorized one? In my case, "successfully" would be mounting a leadscrew and motor without excessive overhang/side forces, and leaving room to mount a Wolfgang Engineering high-speed spindle. I don't quite see a clean way to do it.

The application is the Z axis for a very small but very accurate milling machine to make model steam locomotive wheels (CNC-turn the blank and then mill out the spokes and other face detail.)

Thanks!

Man that website techno sux - Tried to submit a comment via their form & got "syntax error" !!!! AGGHH...

That's why I come here for information.

I have a Techno/Isel Machine, Thoes are used for side rails on the gantry Y
and router head X and maybe the Z with recirculating ball lead screws. My
machine is 6 years old, still very accurate a solid machine. Just their Web
forum and some parts of their site need improving.

Those look pretty cool.
I imagine they would be pretty accurate as well.
I have a large crossed roller slide, but it's fully setup with dual slides and a carriage with ground ballscrew and motor mount.
If you are only using one of these, I think you would have to mount both sides to a plate and then gor from there.
This does have mounting holes on top and bottom, right?

Hi LeeWay,
Yes they have mounting holes top and bottom. My table top is extruded alumn. These mount to the bottom of that then the gantry sides wrap around
to the bottom of the slide, works very well.

Do you have any photo's loaded up?
They might help.

These aren't the big Techno slides (I recently sold a Techno XYZ gantry, so I know all about them.) Forget I said Techno, it was just a convenient link. Pretend I said Deltron...

My slides don't have a manufacturer's name on them. But they look like the following. They are about 5 inches long and have a 3-inch stroke, more than plenty for what I want to do.

Yes, there are some holes but I will need to add more. These look like they were from some OEM application, so the existing holes are at odd positions--not a regular pattern.

But I hadn't thought of adding plates--I was thinking of trying to use the slide as is to keep the moving weight down. Thanks for the nudge--I will think on that.

any update on this? I have one of those slides pulled from some gear I dumpster dove for. I like the "adding plates" idea, maybe think of it like a sandwich, lead screw in the middle there as well... ?

[zephyr9900]

I haven't done much on this yet, jmytyk.

The motor with leadscrew needs to be fixed to one half of the slide, and the nut to the other half. And there needs to be room to mount the fixed half to the machine structure, and mount a spindle or other payload to the moving half.

The slide is pretty small, and there is almost no meat to attach things to the ends of the slide, so it pretty much needs plates attached.

I have two of the slides, and am actually thinking of attaching them back-to-back flanking a support pillar to make my Z axis. The pillar can be hogged out in the middle (to make a kind of thick-walled channel) to mount the leadscrew nut and clearance for the leadscrew, and the moving halves connected by a thickwall angle, which cantilevers back to mount the stepper. Quick'n'dirty sketch below.

I got my Z-axis finished with the slide you were talking about, check it out- let me know if you have any comments
