Faultyblunt wheel on Rubi TX-1200?

[Tilergal]

Hi All, hope you're all busy and well. Quick query: setting a floor with Porcelanosa 660 x 440 10mm thick and using the TX-1200 for cuts. Scoring fine, but tile is breaking off in a curve rather than along the line (almost an S shape). Happened to three tiles now, have scored deeper but no joy . Used for walls and fine (ceramic though) and no problems in the past. Can use angle grinder for now but just thought I'd ask if there's a specific wheel to fit this cutter that you would recommend before I splash out?

Ps current wheel is Rubi 10mm standard, which they state is for ceramic and stoneware.

You could try using rubi's gold cutting wheels never used one But for £15 you could give it ago

I had similar trouble on 1200x600x10 had to angle grind 7 wet rooms 🙁

You know what I'd suggest.... 😉

 

[Andy Rhodes]

get another cutting machine maybe😀

I'd try with the 8mm. That's the one Rubi recommend for porcelain. But if it is going off in a curve, it could be slightly overfired, in which case you would have little success with anything other than electric.

As a guide, the optimal wheels for Rubi cutters are:
6mm = glazed ceramic wall tiles
8mm = all glazed and unglazed porcelain and dust pressed clay quarry (victorian style)
10mm = glazed ceramic floor tiles
18mm = rustic unglazed clay (extruded quarry tiles)

Omg, total nightmare

Cheers Paul, much appreciated

Cheers Andy, I have used the gold before but I'm not blown away

I've got a DeWalt electric cutter which is a lovely beast but would have to be set up outside and running up and down stairs with porcelain floor tiles is getting harder by the year....🙁

 

[Andy Rhodes]

good workout though😀

 

[Andy Rhodes]

seen the Dewalt cutter it awesome ,but can't justify buying it only fix weekends now

got one specially for the job and wouldn't cut them Mark 🙁

Truth is more and more porcelain is being over fired and is impossible to break cleanly.
I'm at the stage where I insist on test cutting before agreeing a price on larger jobs.

You mean "wouldn't" ?

 

[J Sid]

😡yes wouldn't

😡yes wouldn't

Not surprised. Even a magical sigma can't sometimes.

I come across some porc that my sigma won’t cut. Tend to be ones from sheds that clients provide.

Totally agree with you...
Maybe we should all go a strike till the supplier's get there act together....😉

I'll get the ball rolling on Friday...🙄

Had this recently with some tensioned 800's, had 12 on site, needed 12 and it was the last 12 tiles in the country, put a new 8mm wheel in the Tx, cut a small strip off your waste edge, doesn't matter if that breaks off line but it will release some of the tension in the tile then go for your measured cut, it helped a lot I found..

you can't because you all use a push-type tile cutter, try one with a pull. never had problems. 😉
