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

    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...

    In the past I'd be agreeing with your partner.

    My computer usage can be vaguely separated into three categories; work, video games, everything else. For the latter I am an unwavering Mac user. For...

    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...

    9 microns is .00035".

    There are a lot of different models of Doosan lathes.

    I have one that is geared between the servo and the ballscrew, using only the motor encoder for feedback. It is a lot...

    I must say this is not the outcome I was expecting, I assumed he was taking break from posting here.

    Very sad news.

    Thanks again all,

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

    We will saw cut the hole in the existing floor, but I'm not sure what "saw cut" means in relation to the new slab...

    Thanks for the replies so far. This is somewhat outside my sphere of experience so not really in a position to respond, but I am reading and absorbing each post.

  11. 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.

    This is a Japanese machine and the English...

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

    If I'm wrong I will apologise later.

    Well this is certainly an entirely unforseen course of events.

    Sub mods should not have the privileges to issue site wide bans, as if previous examples were not proof enough of that.

    I don't disagree, and I operate a similar-ish setup here. We don't separate serial numbers, but our database allows for owners and designated users etc.

    Sylvac will get that prize every time. Certainly they are more expensive than Mitutoyo, no argument there. But if money was no object all my measuring instruments would be Sylvac.
