    Are you absolutely certain about the coolant routing through the OD holders?

    Just about all the ones I've seen are ported into the bore as well as the front holes...

    If it's an analogue drawbar position sensor then it is most likely configured to work within threshold values.
    In which case it would be possible to overcome the retention force enough to let the...

    At least we can agree on that!



    There is a a difference (I know, it's super subtle) between casually using swear words in conversation with your colleagues, and "cursing, throwing things,...

    Thanks, but not sure what it would achieve tbh.

    I could certainly document the event with an NCR/CAR but it wouldn't have any meaningful effect.

    My experience with anodisers is that they have...

    I actually did something very similar during this last run, very rough and very quick, but it definitely helped.

    Need to do a proper job of it...

    Thank fuck I don't work for you.

    Thanks for all the replies!

    I've removed my fair share of broken studs, and my gut feeling is this one is not screwing out of there.

    Got some more pressing things to attend to first, but plan...

    People swear at work, at all levels, at all jobs. I do it, everyone I've ever met does it.

    If an employee is too stupid to know not to do it in front of a customer, then they're probably too...

    We have this already with the crowned bearing, except it's a single score in the centre.

    Score isn't really the right word as it's not a depression - but it leaves a mark. No biggie as it gets...

    That's due to the "rolling shutter" capture method.

    About the only artifact that might be encountered in this kind of scene from that would be some horizontal shearing, but nothing here is really...

    I admittedly don't have much experience with HSK.

    I do have a lot of experience with 50 taper, and I do have a lot of experience with capto, and I do have a lot of experience with heavy machining....

    Image stabilization as you describe it is how youtube did it years ago, it was absolutely horrible - motion sickness inducing, and caused terrible image distortion.

    Modern digital stabilization...

    Sorry, you posted this while I was typing out the above post.

    Titanium could be a possibility from the apparent hardness. It's not aluminium. Also the part is pretty big and heavy to suspend from...

    Sandvik published a study years ago where they tested the load deflection rates of various spindle interfaces. The purpose was obviously to show how wonderful capto was, but the difference between...

    Kind of hard to gauge the material of the stud tbh from what little of it is exposed, I did a couple of scratch tests on it and it seems pretty soft, but not aluminium soft. Mild steel of some...
  17. Anodisers broke a stud in a high value part...

    They screwed in a stud in order to suspend it in the tank. One of six parts, value is ~£6k each, the other five are fine, unplated in the one same hole so they clearly used the same method on all...
  18. Roller steady - bearing type / surface geometry

    We have a big steady that uses INA NUTR3580-A track roller bearings.

    These have a crowned (extremely slight, hard to tell it's not cylindrical even with a straight edge) outer surface, rather than...

    Thanks for the tip - I have several tools in my arsenal to do a diff compare, but like you said it's an extra step that should not be, and never has been before, necessary.

    This is the kind of...

    No this was on one of our Hurcos, although we do use the pcmcia cards on the Fanucs as well.

    No fault of the machine, it accurately read what was on the pen drive.

    This is interesting.

    In my world, tolerance stacking is a term used to quantify the limits of uncertainty, i.e. it's usually discussed before a part is made, not after. Usually in the context of...

    Serial port transfers are separate from the networking stack on windows, so the firewall has nothing to do with it.
