From my earlier post:
The Mori Seiki has a large 8 stations turret. There is a large hydraulic unit with two 100V valves. It works as follows:
1. The signal sent to the valve and hydraulics push the turret out
2. The turret motor turns to the correct tool position
3. The signal sent to another valve and the turret gets pulled back.
As suggested later it has an electric (3phase) motor and Geneva mechanism.
Thanks, M
