  1. Re: How to mount this linear actuator with flange thing on the bottom?

    Since nobody has replied about the flange mounting option I did indeed end up just drilling holes in the back of the actuator.
    The z assembly will look something like this, with the wood eventually...
  2. Re: How to mount this linear actuator with flange thing on the bottom?

    Thanks for the reply. I had actually started out that way, pulled out some aluminum plate for that and was starting to design it but curiosity got the better of me and I made this post because I...
  3. Re: How to mount this linear actuator with flange thing on the bottom?

    Thanks for the reply.
    I did think about the bolt option but wondered what the real industrial mount for this looks like.
    Perhaps this was a custom case made by ERO for a custom robot and there is...
  4. How to mount this linear actuator with flange thing on the bottom?

    I am piecing together a CNC machine and want to use this part I salvaged from a robot for the z-axis.
    I guess the intended mounting mechanism must be the small flange (6mm thick, jutting out 5.4mm...

    It's not really clear what your question is...
  7. Re: how to find the right driver for servo motor?

    oh, very interesting products, thanks for the link. I should have been more specific in my question adding, "no generic control systems for servo motors... that would cost less than a used driver...
  8. Re: how to find the right driver for servo motor?

    I have the same problem--I got 3 very nice servos off an old industrial robot but have not figured out how to drive them, besides buying an old controller for them which even used is several hundred...
  9. Re: salvaged linear rails + ball screws good for cnc mill?

    Ok, I will try re-greasing, maybe work it in by turning the spindle with a hand drill. Any hints on what kind of grease to use?

    As for the heat management of the Teknic motors, this guy used them...
  10. Re: salvaged linear rails + ball screws good for cnc mill?

    Thanks a lot for that input. It sounds like it might be worth investing some more time into trying to make something out of these rails.
    Do you know if there are any tests I can do to know if the...
  11. salvaged linear rails + ball screws good for cnc mill?

    hi,
    I salvaged some linear rails with integrated ball screws which seem to be extremely robust. It feels like the X-Y axes, which are bolted together, must weigh 60kg although a lot of that is...
