the clamping system  of the rotary tool changing system is a pair of rings with a taper dog clutch that is spring loaded when in normal state, the round part on the back of
the changer is a air piston that has a ball at its end , in the toolchanger shaft is another ball bearing  , when the piston is pushed forward by the air if pushes one ball again the other
eliminating spring friction and pushing une half of the dog clutch away from another, in the pic you can see the dog clutch rotating

Sounds like a nice simple setup and also one that is inherently safe being that it is held tight via spring pressure :)

there is still a lot to do, like installing a limit switch in the piston to let the controller know that the lock is fully engaged,
also im intending to fit live tooling to it,(very hard), you see I program at work a Mori-seiki NL2500 with twin spindles and a turret that
has live tooling , and I get carried away easily.lol

I have often thought about live tooling also, might get round to it one day but unlikely.
