Bit time consuming but id get a new blade on your wet cutter ,my nd200 just packed up but had it ten year ,usedthe best blades cuts anything with ease

Are you using the breaker or jackie channing them?

On stubborn tiles I find that slapping them with your hand works better.
Try adjusting your sigma rail depth so it's scribbing with firm pressure but not causing the tile to ping and snap prematurely. Personally would only scribe once.

I've tried the gentle approach, scribe 50 times approach, jump up and down on it approach.........come to the conclusion there crap tiles..

Can anyone shed any light on why some tiles behave this way.....
Are they bad batches or is something else going on..

Quite often it's because they're overfired mate.
Another batch would probably cut perfect.
You can also just scribe them and use pin hammer along the back behind the scribe.

Try this, when you've scored them at both ends of the tile, score a 45degree off the cut line also then break or snip that piece off, then when you go to snap off at your intended breaking line the tile will break where you want it to because the main body of the tile is on the stronger side of the score line. It works for me every time.

Had the same before, bought bearing wheels and new diff sized wheels for 800mm tile used in a Rubi tx1200 but didnt help, best approach was score 5-6 times till wheel sounds "dull ".
If no results, try grinding top and bottom 50mm them snapping.
With some tiles, theres no guaranteed solution.

As John & Marc said, try scoring top face as normal and then flip over and score same line once on the back. Flip tile back over again and break it as you normally would. Some porcs are so brittle when overfired they wander really badly when broken. I have found this has worked in the past.

call the manufacturer of the tiles and explain how to make the cut. I've already done.
