A meter long porcelain tiles? Where have you had those from? lol
Regarding your chipping. Chipping in usually either down to the tile type, the tiler pushing the tile into the blade too quickly, or not enough water in the wet cutter tray... (or sometimes the water is at the right level, but you have too much sludge in the bottom of the tray so actually again, there's not enough water in the tray).
If you feed the tile into the cutter at say 1mm oer second there would be no chance of chipping the tile you'd have to agree. So generally whatever the cause of the chipping is, if you feed the tile in at a much slower rate, the blade will have enough time to grind away at it's cut rather than it needing to hack away. If that makes any sense.
