"BT6500 onwards, have the new CNC liner as opposed to the cast liner before. "

What difference do you think it ought to make?

The only advantage that CNC ought to make is in production, the liner will still be cast, will still be machined but CNC be able to do more liners than a human and possibly with less variation. It depends on how good the human was and the quality control.

I agree that using good new CNC equipment throughout the manufacturing process might create engines with tighter tolerances but that depends whteher they altered the tolerances too.

Otherwise a machine made by robots should be no better, no worse than a machine made by hand.

The only real difference would seem to be in concentricity, a milling centre will do all the operations off one setup, so a bore can be bored and ports cut off one alignment, where manual methods use different machines with the result differences in alignment.

So while I don't doubt that you found the extra time on the new engine, I am wondering why CNC should make the difference.

(genuine interest, I am playing with CNC tools at the moment, they are great for doing things like complex curves which I cannot do manually without special tools but they don't seem to do anything I couldn't do if I could react as fast as a computer)
