    At least here in the UK Hurco will support old machines.

    They don't stock control parts for the very old controls, but they will support if they can.

    About ten years ago we had a really old...

    I know I may be the exception rather than the rule, but I do a lot of heavy machining with a 55KW ISM spindle with plain 50 taper, and I can tell you without a seconds hesitation that the taper is...

    I have used Deva on a previous project and have talked about them on here a few times before.

    They are good people to deal with, and the products are excellent.

    Interesting challenge! The immediate method that comes to mind would be a qualified gauge with a mounted ball centred on the gauge line. That would allow a cmm to measure the intersection of the...

    HSK is more expensive to produce than steep taper, and more expensive to own.

    So, it is generally specified on high speed spindles, where it is really required.

    The higher the spindle speed,...

    This was actually a contributing factor for not choosing a certain brand on a recent machine purchase.

    Firstly it was it was more expensive, but that wasn't a deciding factor on its own.

    Looks like a very nice height gauge indeed.

    Aside from a separate counter, I imagine that thing is supposed to have an air connection as well. Granite column = probable air bearing. Also very...

    45Rc is not really "hard turning". Hard enough to make life difficult with carbide, not really hard enough to justify CBN, maybe hard enough that ceramics might be effective.

    Also, the difference...

    Very sad news.

    Thanks again all,

    Next question, what do you guys mean by "saw cut"?

  17. What kind of material is normally used for machine foundation isolation?

    The foundation drawing for a new machine purchase specifies 100mm "Styrofoam" all around the slab to isolate from any vibration in the existing floor.

    The probability that Gordon is legitimately uninvolved in Barbter's suddenly being banned is a very, very small number.
