Breton MIRAGE 6 – a Formula 1 “racing head” for levelling granite slabs.

Our CUSTOMERS say so!

BIG, Cereser and Cometti companies have something in common, which is not strictly related to their local identity: these three enterprises from Verona chose the Breton head "Mirage" for levelling granite slabs.

The core business of Big Graniti Srl is sawing granite blocks, polishing slabs and executing several other types of granite processing.

Cereser Marmi Spa is specialized in the selection and selling of marble and granite and was established fifty years ago by Mr. Gian Luigi Cereser.

Cometti Srl, established in 1982 by Mr. Francesco Cometti, is totally committed to granite polishing and, same as other enterprises, has always tried to be in the forefront of the granite honing, polishing and resin-treating technology.

The constant quest for innovation led these companies to install a head "Mirage" (Breton latest product) on their polishing machines Levibreton.   

Mirage is a special head featuring a satellite rotation speed of 30m/s (2.800 rpm) and a low head rotation speed (250 rpm). 
This head guarantees the ideal working speed for each single diamond tool, which leads to a higher removal capacity and longer service life.

The key factors of this groundbreaking satellite head are clearly explained by its possessors.

1. SPEED
"When I was offered to test Mirage, I took delivery of the head with a 18,5 kW motor and a kit for adding the counter pressure to the spindle already prearranged for receiving it" says Marco Poiesi, CEO of BIG GRANITI Srl. 

"Based on tests carried out at Breton R&D Dept., they told me the head could only work with counter pressure due to its weight and removal capacity. Mirage removed so much material that, after the first starting, I asked for a 22 kW motor (instead of 18,5 kW as suggested) in order to use high working pressures as well. I ascertained a levelling capacity on the slab surface that was above and beyond that of the well-known heads SG-8".

2. DOUBLE SERVICE LIFE WITH RESPECT TO THE HEADS WITH OSCILLATING BRICKS. 

"Something worthy of attention? The service life of the diamond tool: indeed, it is proving to be longer than expected" adds Marco Poiesi from BIG.

3. DOUBLE REMOVAL CAPACITY. 

"Both the removal and levelling capacity of Mirage far exceed those of any other head produced until this time; as a matter of fact, we don't use it on very soft materials because we fear going below the material predetermined thickness" acknowledges Domenico Cereser from Cereser Marmi Spa.

4. LEVELLING OF UNDULATIONS AND PRODUCTIVITY. 

"Mirage surprised us: particularly ugly slabs that had to be passed twice through the machine, need just one passage thanks to this new head" says Francesco Cometti from Cometti Srl. "Processing standard slabs, the polishing machine has a productivity 10% higher than that of machines equipped with heads SG-8, that’s why I've asked Breton to install a second head  Mirage”.

Thanks to BIG, Cereser e Cometti for their positive consideration.
Thanks to Marmo Macchine INTERNATIONAL magazine for case history.

Breton MIRAGE - Special high-removal head for granite levelling

Special high-removal head for granite levelling.

Each tool features an ideal (optimal) operating speed ensuring high removal and a longer service life.

The ideal speed of a diamond wheel on granite is approx. 30m/s.

Nobody has ever produced diamond satellite heads with a satellite rotation speed of 30m/s before. Breton developed MIRAGE, a head featuring a high tool rotation speed (30m/s equal to approx.  2.800rpm) and a low head rotation speed (about 250rpm).                    

- Double tool service life with respect to a head with oscillating bricks.

- Double removal capacity with respect to a head with oscillating bricks.

- Outstanding capacity of leveling out the slab surface undulations thanks to the following combined effects:

  - High rotation speed of tools.
  - Low rotation speed of the head.
  - Large volume and high rigidity of the head.
  - Head diameter of 510mm.

- Cost of tooling

1,5  times higher than a head with 8 diamond swinging bricks.

- Tool service life 

2 times longer than a head with 8 diamond oscillating bricks.

- Removal capacity

2 times higher than a head with 8 diamond oscillating bricks.

- Tool cost per m2

62% lower than a head with 8 diamond oscillating bricks.

- Hourly output

2 heads Mirage increase the speed of a honing/polishing line by 10-15% while ensuring an excellent leveling quality.

- Free maintenance for at least 4.000 hours.

- Replacement of gaskets, elastic components and oil every 4.000 hours.

- Bearings must be replaced every 25.000 hours.

- Gears last for the entire service life of the head.

- Using a special kit, it can be installed also on Levibreton KG with 19 heads SG8 at work.

- The head requires a 18,5 kW motor.

- The head requires back pressure.
- It is advisable to install 2 heads MIRAGE on the 2nd and 3rd position, respectively.
- The heads MIRAGE can’t be used on resin-treated slabs since they remove too much material.
