Ever try the tile "cutters" available at home centers? They're not expensive...they range from $15 on up.
Place the tile on the bed, score it, then snap it. Quick, easy, and a fairly clean cut. If it's too rough, the cut edge can be dressed with a carborundum stone which only costs a couple of dollars.
The problem with the abrasive blades is they heat and wobble. It's often the wobble that causes the chipping.
Since you're on a table saw, one other idea...if you're not doing it, cut (using your current abrasive blade) with the glazed (finished face) of the tile facing UP. This often gives cleaner cut no matter what material you are cutting. Finished face UP for a table saw, DOWN with a circular saw.
Lastly, a wet saw with a diamond will give you your best cut. If you have a lot to do, you can rent a day for a day, or buy a DIY quality one for about $90-$100, then resell it when you are done with it.
