  • CMM/Wire EDM

    I've been approached by the tooling dept. wanting to put a wire EDM machine in the lab with the CMM since I have a climent controlled environment. I'm concerned about what the airborne mist will do to the CMM among other things. Any comments?

    Humidity and major EMF, with humidity the main reason for not having it in the lab.

        If the humidity does not get you then I'd bet you might have problems similar to when you have a CMM near welding equipment. That electricity flux is not good around a CMM. Humidity can be controlled right at the WEDM ($$$) but the electricity problem may prove more challenging.

          And, the EDM will become your reponsibilty.
          When in doubt, post code. A second set of eyes might see something you missed.

            Hello,
            Never never never put a WEDM in a CMM lab. I ran older Fanuc WEDM's for aprox 3 yrs and the problems with the water will trash a cmm. Not to mention the airborn polutants if you run it as a flush. Submersible wouldn't be too bad, but the humidity will be a problem.

              Heck,
              even where I work, they are smart enough not to do that!

                Thank for the replies. They go right along with what I've preached since they first brought this up, about a year ago. Now I have something to back myself up. Rebeldude, you wouldn't believe some of these people around here. Most are a waste of air.

                  Well, they have our WEDM's in the same 'room', but not really, with the CMM. IT is a big 'L' shaped room. There is a wall and door to isolate them one from the other, but all on the same AC.

                    The cleaner you keep your machine the more accurate it is going to be

                    The cleaner you keep your machine the longer it is going to last.

                    The cleaner you can keep your machine the more consistant your results are going to be.

                      yep,
                      people who don't run a cmm don't understand that

                        I think the thought of putting them in the same room, is an obvious one for the uninitiated. You will have to educate them, though. Maybe in the the same room, but they must be far apart! The further the better. I have seen places where the put the EDM near the return vents. That draws the air through the CMM area into the EDM area. That seemed to work. But to just put them side by side is a mistake.
