Porcelain Tiles Chipping - TilersForums.com

[kenny mac]

Hi all as said above I'm chipping the porcelain tiles I'm cutting.

I have just bought a Rubi ND180 and a new blade for porcelain tiles and its chipping the tiles not big chips but. My old £20 Plasplugs wet tile cutter dose perfect cuts on the same tiles. It's just not big enough to hold the tiles while cutting them.

I'm not forcing the tiles I'm letting the cutter do the work plenty of water in the tray just small chips all along the cuts.

Thanks for any advice.

Cheers Kenny

Some blades take a while to wear in from new, try slicing down some offcuts..

try cutting a few bricks (red).
without water. Dry.
It needs to re OILSTONES the blades

Dressing stone for diamond blades and diamond core-bits
I use this.
brick about the same result

Is it a continuous rim blade or segmented? For smoth cuts a continuous one is best. For fast cutting a segmented works best.

Bloody spell checker it's a continuous blade

Some saws have a slight wobble on the spindle. They'll chip no matter what you do due to the slight left-to-right motion on the blade as it spins.

take it out sling it and replace with a marquist 850 all my cutters are using marquist 850 blades no problems
another thing with the rubi 180 set the blade to the depth of the tile plus 10 mm cuts better than at full depth

Try using a different blade. If it's the 180 with 2 blades and case then I believe, if memory isn't failing me, they are segmented. Which can be a bugger for porcelain. Try getting a continuous blade as mentioned above. Give Rubi a call too if it still gives you trouble.

On a side note, don't ever use WD40 on the ND180. I've got two in the warehouse that are covered in muck from that being used to clean them. It will just make the dirt stick.

Exploding pudding yes it came in a case with two blades both blanch for ceramic so had to Buy a red one for porcelain tiles thay are continuous blades

What on earth possessed someone to use wd40 ?

Cheers everyone

I wouldn't touch the Marcrist 850 blades as they are ok but not the best, I used them for a while but then moved onto the Montolit blades & now use ATS blades specifically.

make 10 cuts dry. These use concrete blocks. That you'll see it works. compry?

@kenny mac I hope myself understood
if you want to try.
I had problems with core bits Montolit. continuous rim.
called Montolit technical office.
Montolit said: do 10 dry holes, with brick, the photo posted above.
later improved a lot.
