    Hello!

    Model UIM-23 (уим-23)

    Anybody used one?
    For what kind of use its made?

    Its similar to this:

    You might get replies if we knew how much it cost. At "the right price" you could maybe resell (at a profit) if you can't use it yourself.

    Machines like that are specific to measuring small flat parts. Although you might be able to measure round parts if they are not too large in diameter. Best use is for things like small stampings. Most of that is now done with cameras.

    These are the accessories what comes with it. The owner has not decided about the price yet

    This machine seems to have X and Y axis optic scales.

    Without a price how can anyone advise? If it's something you know (not feel) you can use decide how much you'd be willing to pay.

    As good as all those types I've seen have X and Y scales. Not much use without.

    It certainly looks good but are "spare or reserve parts" (if necessary at some time) a possibility?

    You can be sure of one thing, this tool will be worth far less without the accessories. Now it must be determined if all the accessories are there to make them work. Getting spares will probably not be easy.

    The one in the Russian link looks like a russion LOMO copy of the Zeiss-Jena Universal measuring microscope (Zeiss being east German, and the obligation being to "Share the fruits of our labours with all our socialist brother nations". This is also how a lot of chinese microphone-makers (I know..) are using German technologies from Neumann, world leader in condensor microphones, who had a department in Gefell, in the East of Germany as a shelter from the Berlin bombings during WW2.

    That's really a handy piece of kit, and, with the right accessories, capable of measuring a wide range of stuff to µm accuracy. The way it works is to zero on one feature (X or Y , not Z) or degrees with the proper round table, and then by moving the measured object to the "other" feature in the main microscope ocular, and reading the difference, by adjusting various knobs and reading various measuring eyepieces.

    the main column can be tilted to allow for the pitch in thread measurements (i.e. looking at it slightly at an angle to follow the thread). various eyepieces were available to measure various metric thread piches (ordinary 60º and trapeze), and TPI for Whithworth 55º as well as some pre-defined radii.

    Also an ocular to measure angles was usually standard (on the old machines that i know of).
    the profile projector-head thingy was an accessory which fits over the eyepiece - it wasn't a real profile projector.

    For a current offer in Germany:
    universal measuring microscope u used machine for sale No. 124184294

    Russian accessories have a lesser finish than the Zeiss stuff, which is gorgeous. and may well fit, but may also need alterations (e.g. thread length and engagement of the Russian objectives is different, event though the tread itself is the same)

    This machine was made, I think, primarily for the checking an measuring of gauges in the days before CMM - which is where Zeiss has shifted their focus to.


    From the accessories you've shown, it looks like a newer version, which is probably good.
    The original Zeiss stuff was, for a period, sold as "Jena" or "Aus Jena", because Zeiss Oberkochen(West Germany, where the allies settled the firm down after looting the Jena factory) won a trade-name dispute.

    sometimes these, or accessories, turn up on German ebay, look for "Werkzeugmikroskop"(tool microscope ie toolmakers microscope). or "Universal-messmikroskop" prepare to look long and hard.

    If you have the room and it's a bargain, I strongly advise you to get it.
    When I was trying to sell a watchmakers' lathe, I just put it under the microscope and measured alignment accurately to within 0.01 mm. great stuff. I have a Large toolmakers microscope from Zeiss (smaller then "yours"), and mostly it does nothing but sometimes nothing else will do.

    Happy Hunting,

    Hans

    Been asking for the price, no progress on that... Atleast the "optic" scales work x and y, no idea of the resolution on them.

    If you have a use for it, 500 euros is a steal. Get it.

    If you have no use for it, no sum is low enough.
