Appartment development: opened for myself the right way to saw the tiles.
Feel so incredibly stupid that I did not use it before.
I used to saw the whole tile by corner grinding machine, since I did not see the proper rotating disk cutter which was capable to cut my ceramic tiles or granite. This process produced tons of dust. Well, maybe not tons, but anything in the appartments was covered with quite thick layer.
The first main problem to cut the tile is its glaze. This glass-like material is extremely strong in some tiles (especially for the ground cover). There is no such layer in the ceramic granite, but this material is very strong itself, which is the second main problem.
So, to cut the tile one has to scratch the whole glaze layer, and only produce very thin scratch so when force is applied to break the tile, the smallest energy level would be located along the scratch.
Today I opened a new way, which is basically above scratch, but made with the corner grinding machine help, which saws the glaze layer. To work well the sawed line should be as thin as possible, which is not that easy using my favourite device.

Moreover the sawed line will not be exactly straight and will contain upto couple of millimeters non-straight places, which may be ‘polished’ by the back side of the disk, it is covered with special scratches at the edge as you may see. But in the most cases the tile is sawed to be placed near the wall or when holes between tiles are supposed to be filled with the special plaster, so this will not be a serious problem.
Here is what can be quite easily made with above method.
Scale is quite big, for the comparison the width of the sawed scratch is about 1-2 millimeters.
Not perfect, but if needed it can be polished. Main advantage of the method (guide in pictures) is amount of dust completely non-comparable with the whole-line sawing with essentially the same straightness. It is also much less noisy.
