Some figures on the last Glasstec.


The show held in October 2018 in Dusseldorf saw a growth of almost 5% in the number of visitors, slightly lower than the records of 2012 and 2014.


The show is truly an international fair with more than 70% of visitors coming from abroad.

On the other hand the number of exhibitors is in withdrawal (figures not given by the organizer) with some hall not completely filled

New options for Battellino robot for double glazing


- BAR CODE READER: this allow to the customer to create bar codes that can give the machines all the information about: Type of frame ( aluminum stainless steel) thickness of the 1^ 2^ and in case of triplex 3^ glass; Thickness of the frame; information if the glass is a simple double of a triplex.

- SHAPED GLASS a special environment on the panel ( see attachments) allow the customer to choose from different kind of shapes of glass to work.

- MONUMENTAL GLASS opportunity to work also frames of only 4 mm, this device is particularly interesting for the companies that work with restoration of old buildings. Really interesting because this kind of glasses are really difficult to job well also manually.

-SPEED faster then in the pass the new version runs at 18 mt/min also the working of the corners was modified to run faster ( a glass of 100x80cm can be done in approximately 45 sec.

- NEW TOUCH SCREEN PANEL if in the older machines were equipped with a commercial PC, the new models are equipped with an Industrial panel, more powerful and more reliable, like in the past, also this new touch can be delivered in the language of the customer.

- NEW PUMPS thanks to a new supplier that helped us creating with us a special pump for our robot we have had the opportunity to offer the robot with a better price

- 4.0 MACHINE the machine can be certificated as 4.0 industrial machines that means higher score to access to European founds.

Technical news for Battellino Italian machines manufacturer

- STRONGER INLET AND OUTLET ARMS we change the system of inlet and outlet conveyor to allow to our machine to can sustain more weight following the requests of our customers.

- NEW GASKET SYSTEM  to help our customers to maintain in better conditions their machines, we modified the gasket set of our spindles, to avoid more and better any problem of leak of water.

- NEW WIDE TOUCH SCREEN we improved our machine with a multilingual wide touch screen. The panel, equipped with our new software divided into environments,  gives to the operator the opportunity of set easily the speed of work, the thickness of the glass, the operations of the pneumatic motors and the working of the water pump moreover shows to the customer , the total and partial meters worked by the machine, the way of working of the machine in each phase of work, helping him also in the maintenance of the parts.

- NEW SYSTEM OF GUIDES FOR THE DIAMOND AND POLISHING MOTORS,  a new system of guides for the motors give them more stability to improve more possible the quality of the glass.

Cutting oils for flat glass processing


Why to use cutting oil?


The glass cutting is generally done in 2 steps


1/Achievement of a crack on the glass surface

2/Breaking with a mechanical action, moves the crack up to the other side of the glass.

For glass under 10 mm, the breaking is not necessary because the glass is completely cut (open cut).

The cutting is done by a diamond tool (mini disk).

The parameter to adjust to have a good cutting

-The tool angle with the glass surface

-The cutting speed

-The cutting pressure

-The tool diameter


The crack must be perpendicular to the glass surface, and without  (no other crack starting from the main crack)

The tool cuts the chemical links between the silica atoms. But the glass is a viscous material. So depending the temperature, the time before cutting and breaking some links can be created again, doing the breaking more difficult.

Moreover during the cutting some very small glass pieces can link with the surface or create scratches on the glass.


Glass oil cutting action

-Improves the crack quality (direction, less alternative cracks)

-Prevents the new silica links

-The glass surface lubrication decreases the scratches number and improves the life duration for the cutting tool.

-The small glass pieces created during cutting remain next to the cutting area.



Glass cutting oils different types

At the beginning were only used mineral cutting oils. But they were difficult to remove and let marks on the glass during the following processing (tempering, laminated glass cutting, fusing…)

After washable cutting oils were proposed.

But if these cutting oils were not removed before the following processing they let also marks on the glass during heat treatments or polluted other processing.

Then evaporable cutting oils were designed.

With variable time before the evaporation to have the best efficiency

The cutting oils must not affect the material where they are used (wood, plastic, cutting table carpet…), Low e glass, mirrors….And more important the operators.


There are a lot of different cutting oils depending the glasses thickness, the cutting type (straight or shaped..).
