    It does work, and it works very well. Right now, the only De-Vibe tech that exists for rotating tools, exists for face-mill & disc-mill holders. There exists a few where the holder is a tapered-nose body for screw-on 1"-1.5" indexable endmills, but we're still talking only holders for large-ish cutters right now.

    Knowing how it works though, I can't imagine someone hasn't tried making a version of De-Vibe holders for endmills yet. You'd end up with a large diameter holder relative to the endmill, but no reason it has to be larger/bulkier than a milling chuck really.

    Ha!
    They are way behind the times!
    Vision Mfg has been making smart tool holders for multiples of minutes, at least!

    The cost these holders would double the value of our machines.

    Are they balanced? :-)

    Not worthless & not prolly cheap. A traceable accelerometer (good) is very expensive.

    Never seen one in a toolholder but the tech has been useful since the beginning of the jet age when just attached to the machine structure. Three accel’s can tell you a crap ton about what a machine is doing & yea Tom’s spreadsheets would love it.

    I would expect that toolholder for sale would be between G1 & G.04 on balance… Fairly high money just that part of it. You don’t have to go balls out to get a good kit to work with your machine, the IRD810 (what, 40 years old?) goes for way less money than the traceable accelerometers & transducers alone cost these days on fleabay. Oh, & the shock rating on the 970 piece is 2,000 G's, everybody close is dead by then...

    Good luck,
    Matt

    Personally I'd settle for some intelligent operators. Just sayin'...

    That'll cost you 70k a year per seat easy, not to mention the 5k yearly maintenance and you know some year they'll come out with an update that makes it unusable to you. Then when you ask for the old one back they'll just say it's no longer supported.

    But if a guy had competent operators all that would be irrelevant, wouldn't it? I can still post from V7. But because I'm able to do the job as described, it doesn't matter if it's supported or not.

    Your point about fine balance does raise a good concern regarding the endmill design.

    Many modern endmills are now sporting asymmetric flute spacing to prevent the creating of harmonics - But what's that do to the balance of the endmill at speed? Since we're talking long, hydraulic holders, it's safe to assume we're talking 8-15k RPM anyway...

    Certainly they've taken this into account? I wonder how much thought the endmill manufacturers are giving to the radial balance of the ENDMILLS at speed - especially with asymmetric flute spacing - and now asymmetric helix angles, radial rake angles, etc... I can imagine a few grains of carbide at 15k probably makes a difference to balance.

    SOOO - Is the iSmart toolholder able to filter out imbalance of the rotating tool assembly? Does it really matter?
