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 ...)

Half jumbo cutting table


The half jumbo glass sheets (generally 3210x2400 or 3210x2450), are found in small or middle sizes glaziers or in country where the jumbo sheets are not available.

The cutting table is generally proposed with :

An horizontal surfaces covered with carpet (more often tilting to make easier the loading) and supplied with air cushion to make easier the glass movement on the table. Moreover for the breaking the cutting table is equipped with 2 or more breaking bars, and some control pedals (to manage the air cushion, the breaking bars…)

A cutting bridge

A numerical control (CN) which drives the cutting bridge and where the operator has the possibility to enter the data for the glass cutting.

An software

This software can be supplied by the cutting table supplier or by a software company specialized on software for glazier for the more important glaziers.

All the data concerning the cutting are generally entered before to start the cutting, the software managing the cutting optimization depending the glass thickness and dimensions to cut for the day.  Very often the software manage also the glass stock.

The working cycle is:

Entering  (directly on the table or from an office) for the cutting data in the numerical control.

Glass loading on the cutting table

Automatic  cutting



The slow step for the glass cutting is the breaking. For the glazier having important cutting to carry out (mainly for thickness over 10 mm) a breaking table is added after the cutting table where one or two operators can break the glass during the glass cutting on the first table. The glass is sent on the breaking table with belts or using the air cushion.
