We run three Nakamura Tome machines, a WT-250 and two WT-150s, all twin spindles, twin turrets, live tooling on both with Iemca bar feeders on all three. Live tooling adapters can be expensive, but we run hundreds of thousands of the same part so it pays not to have to handle them again and put them in a mill.
They stay up and running pretty much all the time. We bought a used one in 2011 and all I've ever done is change the batteries in the amplifiers.
There's some great people just down the road at Tennessee Industrial Electronics if you do need parts, and they always seem to have what we need and it's almost always here by 10:30 the next morning.
