The cutting of Porcelain tiles, 16mm, with a Vitrex bridge saw, has been very successful, holding cuts of 900mm to 0.4mm.
BUT
All the blades I have tried, ATS, Marcrist and Rubi, have all started to cut off centre.
I have dressed the blade with a Rubi cleaning block and this will improve cutting but it doesn't seem to cure cutting off centre.
For some reason, after a load of cuts, the blade will start to deviate from where the machine carriage is going. At the end of a long cut, it can be as much as 2-3mm off centre and you can see the blade flexing sideways.
My theory as to why this is happening is that the edge of the blade, although 'sharp' with plenty of exposed diamonds, is no longer square. It's rounded and the rounded edge is not even.
Of all the blades I have tried, Rubi TVH was the worst. It cut the best, with lower noise, less chipping but didn't last half a day before it started to wander off.
So am I right is thinking I need to square up the blade? If so, how?
The blades seem to cut through the cleaning/dressing stone really easily. Do I need to make the cut into the dressing stone more quickly?
Do I need to dress the sides of the blade?
Is there some other way to recover the blades? Thay all have lots of edge left, it's just not square...
Any advise muchly appreciated!
