Mikron mill

I'm looking for information about an old Mikron vertical mill that a
friend has, the one with a flat belt drive.
Does anybody know what sort of collets are used, they don't appear to
be morse taper? They could be the Brown & Sharpe taper but I'm not
sure.
I've looked on the Lathes web site and couldn't see any specific
information as to size/type so any information would be useful.
Apart from collets he could do with a milling chuck, any ideas what
might fit?
Thanks in advance

My advice is get the spindle modified to accept a more common collet. That is what I did with my Herbet 0V for which collets are near impossible to find. Now I use R8 tooling in it.

There is very little paperwork on Mikron kit, but they did have their own collets for the lathes which held up to 5/8" diameter, they are conventional drawtube type and are available. If these are what is needed, I may be able to help. I also have some copies of old Mikron sales literature. Peter

Hi Pete, John,
As far as I am aware, these are similar to Schaublin W20 collets, however with a 2.0 mm thread. At least, these are the ones that came with my F75 mill.
I'd be interested in any sales literature that you have. I have one catalogue .pdf myself and haven't been able to find anything else. I also asked the Mikron company, but they couldn't help me further.
Best regards,
Wouter.

Re literature for Mikron, the Lathes web site has a lot of information on Mikron machines.
The only thing I have learnt otherwise is the thread on the collets is a 2mm pitch buttress form.
Which raises a question, where would I find a screwcutting thread gauge for buttress form threads?
This is just for my info as the person has the Mikron appears to have lost interest in doing anything to it.

If you are screwcutting, do you really need a thread gauge ?. You can grind a tool using an unused portion of the collet thread as a gauge, then use the lathe and dial gauge to cut the desired depth. Again, using an existing collet as a gauge, you can bore and screwcut an internal gauge.
Shame, as it sounds like a nice piece of kit. I'm still looking for a vertical head for my Centec, or anything else that could be coerced to fit...
Regards,
Chris

I'm looking for a vertical head for my Centec 2A, I have a grinding attachment with mine which I've not seen anywhere else.

Hello John,
I'd be interested in any of the Mikron Mill accessories that he doesn't use. Please contact me if there is the possibility of buying any from your friend!
Best regards,
Wouter.

Hi Wouter
There is nothing for sale - he has just lost interest in improving what he's got.
