    Thanks Vanc, was hoping you'd respond. You're pretty much thinking along the same lines I have been, which is reassuring!

    The bolts on the labyrinth cap were tight, and there was no crash, and it...
  2. Lathe spindle repair, spun bearing, lost preload

    Lathe in question is a Victor Vturn 36, which is really a carbon copy clone of an old Mori SL-35. It's a 1997 machine, good working order, but not worth a whole lot.

    Noticed that we were getting...

    The real beauty of WNT/Ceratizit is not their indexable tooling, which is pretty standard, but their solid tools.

    Their selection of endmills is just vast, and covers every possible scenario. A...

    This was done and dusted a while ago, but I was putting some tools away and remembered about it, so decided to update in case anyone else needs to do the same in the future.

    The two modified tools...

    For the two hundred and umpteenth time (not looking at you specifically Rob) PSI/KGcm2/Mpa/whatever unit of pressure you like to use is a completely and utterly meaningless way to represent gripping...

    I am under the impression that the DMG side are still built in Europe and the Mori side are still built in Japan. I'm not sure if there is any crossover.

    At least, our NTX is coming from Japan.

    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...

    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...

    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.

    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...

    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...

    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...
  25. 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...
