Rubi Diamant Dw 250n Problem

[dziqs]

Hi guys

My rubi wet saw, when using it for 45 deg cuts, won't make a straight line. Let's say I need the tile to be 300mm wide but end up with tile which is on one side 300mm and on the other 292mm. Have you got any ideas how can it be fixed? I tried to adjust it on the bolts which holds the arm but it didn't work. Is there any place in London where it could be rapaired?


Thanks for any help

Used to have the same issue, Only way i could get a decent cut was to mark the tile with a wax pen and literally steer the wheel on the line otherwise it would wander all over the place

You're talking about mitre cuts yeah?
U've said u can't get a parellel cut so I assume that's what u mean and not diagonal cuts.
Does it cut perfectly square on a regular cut?
If so, the machine is probably fine, unless u have the stops at each end (if it has them) set differently, that'll twist the gantry.
It's just as likely to be a combination of other things.
Trying to move cutting head too fast, worn or incorrect blade and workpiece moving or lifting on cutting bed, especially with hard porcelain.
As you run down the piece, the blade is naturally pushed away from the edge that you're cutting.
So if your blade is worn or too thin this will magnify the problem.
Certain blades are designed especially for cutting mitres, the centre section of the blade will be thicker and therefore reducing the possibility of the blade flexing.
The Montolit DNA is a good example of a blade designed for mitring.
Also the problem can be exacerbated by the work piece lifting slightly from the cutting bed, try clamping it down so that it is solid and won't move.
Can't be 100% sure this is your problem, but it may well be a combination of them.
I'd try looking at these issues first before spending money on a service that may or may not be needed.

Damn. Cutter for £700 which was used maybe on 5-7 jobs isn't working as it should.

Yes I'm talking about mitre cuts. The regular cut is OK. Once set to mitre cut position, even without the tile on the machine, I can see that when I slide the blade (as I would do to cut the tile) the blade in end position is closer to the edge of cutting bed than at the start position.
I bought new rubi blade, suitable for mitre cuts and porcelain tiles so it's not that.

Do you think there is any place where it could be repaired?

I'm sure Rubi uk can advise you where to go.

Do you have an adjustable stop that the gantry sits against when u tilt it over?
It may be misaligned, twisting it.

I phoned them a while ago and they said they discontinued making that model (rubi diamant dw250n) and they can't help me. They didn't know where to go neither.
I received from them the "Electric machine alignment" pdf document and after doing that it got only a little bit better. I couldn't adjust it more and when I wanted to do the straight (not mitre) cut I had to readjust it again..
I don't understand why such a machine (good brand) used not so many times can't do the job.. Maybe that's why they stoped making this model..

Contact Derek at sigma uk. I'm pretty sure he could sort it for you!

Derek is from Sigma and he's not dealing with Rubi cutters..
Any other suggestions? Or this saw is just for skip now?
Cheers

Sorry I was being facetious - I meant Derek could sell you a real saw!

I got the Sigma quip!
Try your local CTD - they often have Rubi repair/service days ( they do in the elite part of the country -Newcastle) and they maybe able to tell you the next or nearest branch hosting one .
