Didnt know ( doh!)

As probably all of you know ( obviously not me) when cutting with a sigma wet saw. Placing the tile face down, makes a far better finish.

Wish someone would have told me as I have hated this cutter since getting it ( having to use as my d2400 has been nicked)
Getting on a lot better now having been forced to use it.

not something I knew either, but I'll bear it in mind if I ever get one.

Me neither...

How does that work then? Are you not getting any breakout on the underside of the cut?

Is that a limestone in the picture Paul or a porcelain replica?

 

[Chalker]

Don't know why it works, but it does! It's a near perfect finish. It still chip when cutting the face side up.

the tiles are vileroy and boch extremely hard porcelain .

 

[Chalker]

If you notice on the pic, with the face of the tile down, it chips out the back.

Is the blade turning in the right direction, as you push the tile in to the blade sounds like it's rotating up into the tile not cutting down onto the tile....if see what I mean.

 

[Dougs Third Go]

does wheel/blade spin counter clockwise then?

 

[Chalker]

It cuts the usual way for this machine, i.e. towards you ( like a circular bench saw) so wants to push down the tile.

snap!!

Spin the wheel when power off to see if the bore is slightly off centre. Had once a few years ago with a wheel I bought for my SMS Clipper, changed it and all was fine after that.

Wheel is fine, it spins the correct way..
It cuts pretty good with the face of the tile upwards. All I'm saying is its even better when cut with the face down. Can't for the life of me explain why!:lol:

I have noticed this on my 9p too

i am sure as can be that you are not supposed to cut with face down. ive had the sigma 9m and 10m for more than 15 years and they are great saws but in fairness i have not used much on porcelain.

Well I'm baffled, but if it works then why not?

It's the angle at which the blade hits the glaze.
Upside down on the Sigma, the angle is increased closer to 90 degrees slightly.
I've noticed the same on my DeWalt. Normally the blade is set as low as possible but some glazed porcelains seem to chip less with the blade set just enough to get through the tile.

I sort of get that.
