My Emco Compact-8s have the 3 M8 nuts to hold chucks on to the flange - it
does not have the rotating collar.
I find it fine - I don't change chucks that often (like, the ER-25 collet
adapter has been on there for a year). Changing is pretty quick, but there
is an art to getting the nuts threaded
Nice. Unfortunately this particular job is cost sensitive so I'm

If you're planning to convert it to cnc - The only thing you really have
to worry about for parts are the spindle bearings/gearbox..
