  • Holding parts with magnets

    How much will a magnet affect the CMM probe? I have some small parts I need to do a gauge R&R for, and it would be a lot easier for me if I could use a magnetic v block to hold them in place. The probe will be close to the magnetic v block surface.

    I use magnetic fixtures/v-blocks/circular mag chucks all day long.

    I always have the magnet turned down as much as can be (while still adequately holding the part of course) and do my best to keep the probe away from the magnet.

    The only way to know for sure is to try it out, do some testing, and hope for the best.

      There are styli with a ceramic stem if you want to probe around anything magnetic as long as the actual probe mod/body isn't getting too close to the magnets.

      Double check with an alternate method to find confidence in your results.

        There are magnetically shielded TP20s available as well. I've never used them though

          That's all I have, non-inhibit TP20 pucks. They are not effected by magnets. I think that if you are using a rack, you have to do it differently due to that.

            I'll give it a try then. These are small parts, and clamping them down would have obstructed most of the part.

            Thank you!

              I have them too. With the rack, right before the probe change, you have to turn on IGNOREMOTIONERRORS then after the probe change turn it off.

                So in order for them do use a rack AND these pucks, you need to have a newer style controller.

                The IGNOREMOTIONERRORS command (and a few others) won't work on older machines
