Convergence of machines for stone and glass

The arrival of industrial synthetic materials on the stone market has surprising consequences on the machinery market. In fact, we see appearing from certain suppliers who are both on the glass and stone market on the stone machinery market, machines that were once exclusively used on the glass market.

 

Mainly for two reasons.

 

1 / These new materials are calibrated in thickness.

So we see machines appearing for polishing the edge (Bavelloni, Intermac, Bovone) similar to those used for glass (rectilinear, double edger).

 

The gain is much better productivity for running in and polishing the edge.

 

2 / Some materials are based on glass

 

We are witnessing the arrival of cutting systems from glass much more productive and easy to use (cutting tables, at Bavelloni, Intermac ...)

Water treatment installations

 

The main reason for water treatment during glass and stone processing are:

 

The anti-pollution rules in the area where the workshop is located

Environmental deference

Cost reduction by an important decreasing in used water quantity and in tools (wheels).

Profit for the machines cleaning time and maintenance cost decreasing.

Improving for glass processing quality.

The water is mainly used to cool the tools (wheels) and the glass. When the silica is not removed from the water the cooling property decrease and the processing temperature is not the right one to have a good processing quality and to have a good duration for the wheels.

On the market exist 3 main technologies

Centrifugation:
benefits:

no chemical products

disadvantages:

does’nt remove the very small glass particles

Purchase cost

Maintenance cost

electrical consumption

Noise


Centrifuges with wheels exist on the market. This way you can move the centrifuge from one machine to another one when you have only 2 or 3 machines in your workshop. In case you have more machines you have to install a fix centrifuge and to connect it with your water treatment network.

Some suppliers propose to add to the centrifuge a flocculation installation to remove the smaller glass particles.

Flocculation:
Good results if the supplier has a good experience and if the machine is properly designed. You have also to find out the best flocculant for your activity (glass or stone or both materials).


Filtering:
Here no miracle. There are also on the market systems associating flocculation and filtering.

 

 

Before to take a decision you have to check if the water quality after treatment allow you to use this water to cool the spindle for a CNC machine (internal cooling).

 

In case of important temperature the water treatment installation can produce some smell. It is better to have the main part of the installation outside the working area.
