Problem with my wet cutter wheel?

[John the tile]

Hello,

Ive noticed over the last few days my wet cutter is not feeling very smooth when i go through ceramics...... some shards flying off when i cut.... which is unusual?

I noticed when I turn the cutter off and the wheel slows down you start to see it moving from side to side slightly which becomes more apparent when it does its last few rotations?

Ive took the wheel off and cleaned behind and around it. The round screw which the wheel slots onto looks straight enough...?

Any ideas, its a Vitrex - QEP Pro-750 Wet Saw 110v.

thanks

Is the blade bent/warped? How old is it (the blade)?

 

[Del W]

Its not sitting right or the blades bent

Any play in the spindle ?

Over heating or forced cutting can cause the wheel to warp... deffo sounds like it as you say it wobbles as it slows down..

Run a piece of sandstone through the saw dry to open up new diamonds and then try again.. but if warped it will not get rid of the wobble.

Lay it on a flat surface and put a steel rule across it to see if its flat. You can usually see if there is a gap underneath it anywhere.

Sometimes they blade 'flares' from side to side when you push a tile in too hard as the blade flexes under the pressure but can seem fine when you run the saw with nothing in it.

I bought a new marcrist 540 blade for my plasplugs which i believe is the same spindle diameter and blade diameter as the vitrex, and its nothing short of awesome on marble. Its really thin so cuts very fast. Not cheap at £45 (ish)but time is money!

You might better off with the warped blade rather than B&Q:lol:

b&q for a diamond blade , is it april the 1st again

I tried one once, in desperate need while working away from home. It was the turbo type but chipped all the tiles. It soon went in the bin.

throw the blade and see if it comes back to you in a big arch as for B@Q blade are you joking

Do you mean the CK850? I've had one both for my Vitrex and my Rubi LS200LPS. Wonderful if expensive.

Aplologies it was the CK650

I put a marcist blade in my vitrex, which was a great machine for ceramics. One day was on a porcelain job, and on one cut, I noticed the blade slowing down very slightly, a melting plastic smell, and then it all stopped. Took it all apart and the motor had got so hot it had melted the plastic casing it was in, which caused the blade to drop and tilt, and the blade cut through the bottom of the water well, and had started cutting a groove in the concrete below it!

Blade is still fine (amazing blades) but the vitrex is in a skip.

I remember doing a granite floor (proper granite) with a mini plas plugs cutter that over heated after 2 tiles. It would take half an hour to cool down enough to cut the next ones. Took 2 days to do the cuts on that floor!

its not normally hard to straighten a steel blade sometimes if it just a little bent just turn it by hand with something just touching as you turn it you will see if a gap appears if it does turn it till its touching again then tap it with something and see if you can straighten it
