High Alumina Ceramic Tiles

I need to cut High Alumina (95%) Ceramic tiles on a regular basis, Tile sizes can be around 400mm (W) x 400 (L) x 55mm (T).

Any suggestions...

A tile saw? If these are too thick for a tile saw, you could use a brick saw: MK Diamond 150598 MK-2002 14-Inch 2 Horsepower 115/230-Volt Brick Saw - Power Masonry Saws - Amazon.com

I wouldn't want such an abrasive material being given free reign to my tormach.
