Affutage des forêts diamantés pour le verre plat

La partie active d’un forêt diamanté, celle qui va permettre de percer le verre est constituée de grains de diamant. Ces grains de diamant sont noyés dans un alliage métallique qui a pour objectif de libérer peu à peu le diamant en surface du forêt diamanté de façon à pouvoir percer le verre.

En perçant le verre la partie supérieure du diamant va se briser peu à peu.

Ce liant doit s’user à la même vitesse que le diamant. S’il s’use trop vite il y a trop de diamant en surface et le forêt va s’user très rapidement et il y a un risque que le perçage se fasse avec des écailles. S’il s’use moins vite que les particules de diamant il n’y aura pas assez de grains de diamant en surface et le forêt ne percera plus le verre correctement. Dans ce dernier cas il faut affuter le forêt de façon à user le liant et refaire apparaitre des grains de diamant en surface. On utilise pour cela des pierres synthétiques, généralement en oxyde d’aluminium.

Mais le besoin d’affutage des forêts devrait être rare, du moins pour les meilleurs forêts diamantés. En effet les fournisseurs qui sont dans ce cas utilisent des liants qui s’usent à la même vitesse que le diamant et donc sans besoin d’affutage.

L’affutage est un réel problème dans le cas des perceuses automatiques.

Sharpening on straight grinders, bevelling, CN ...

Why is it essential to sharpen directly on your machine diamond grinding wheels and  drills you use?

The active portion of the diamond tool mounted on the machine consists of diamond grains which are trapped within a binder. In contact with glass surface diamond grains are broken by lapping the glass. This requires the tool to be effective there permanently diamond grains that outcrop the binder.

It can happen for various reasons it did not sufficiently diamond surface of the grinding wheel or drills (for example, because the binder does not wear properly). In this case it must pass an abrasive stone surface of the tool (when running) to use the binder and slightly re-appear on the surface of diamond grains sufficiently active.

Please note there are several types of grinding wheels as a function of the sharpening tool (grindstone binder metal, resin, diamond drills ...)

Bluetooth glass enclosure Sony

Life With Space UX, Sony wants to demonstrate that it is possible to design a hyper connected housing, where technology is everywhere, without being aggressive. The enclosure that the company present at CES abounds in this sense: it is a kind of lantern with LED inside that hides a Bluetooth speaker.

This is the glass that makes pregnant Office, and the result is quite impressive.

Sony expects to sell this Bluetooth speaker like no other in the spring, but remained evasive on some points. Autonomy is particularly unknown, as is the price. The product is clearly not cheap and should be produced in a small number of copies, Sony's aim is above all gradually start marketing which were previously only futuristic concepts. But the promise, however, proves interesting.

New offer aluminum Fire safety by Technal.

To meet fire regulations, which requires that public buildings and collective dwellings are equipped with systems protecting persons and property during any outbreak of fire, TECHNAL launches new PYROAL OFFER SAFETY FIRE. This technical solution enables aluminum to compartmentalize the spread of flames and smoke, and enhance heat resistance.

The building market  could stabilize in 2016 in France.

The activity of the building industry (including markets of mirrors and marble) in France could stabilize this year, which would end a "continuous slump since 2012," said Thursday the Confederation of Crafts and small construction companies (Capeb).

With a decline of 2% in volume last year, reduced to -1% last quarter, 2015 "ends with less degradation of the activity of the building crafts," announced during a Capeb press conference.

However, this is the fourth annual decline of activity in the sector, which lost another 15,000 jobs last year, lamented Patrick Liébus, president of Capeb.

"Fortunately, the 2016 outlook is less dramatic, thanks to devices for the energy performance of new and accessibility of the built," he has said.

If it is "hard to be optimistic" vis-à-vis 2016, for Capeb, it's a little more confidence, building on "a change in volume of 0-1%".

Indeed, a "less degradation in new markets and the energy renovation and accessibility, should create more favorable prospects", which would "stop the continuous slump since 2012".

For Capeb, "speak of real recovery is premature, however, while the unfair competition and lack of consumer confidence ostensibly inhibit the growth of the activity of the building crafts."

In the fourth quarter 2015, the activity in the nine still yielded 2.5% (against 5% in Q3), while it remained sluggish in eco-renovation (against -1%).

Over the whole of last year, the activity in the nine fell by 4.5%, but the sector has benefited from the growth of energy performance works (+ 1%) and the resumption of sales of existing homes .

Despite this, the maintenance and renovation activity fell 0.5%, as in 2014.

As for the improvement seen since August 2015, sales of new homes, it "should take effect sometime in 2016," said Capeb.

In early January 2016, the order books represent 72 working days, or seven days from a year earlier.

For 2016, Capeb expects a decline in activity of 0.5% to 1.5% in the nine offset by an increase of 0.5% to 1.5% in the maintenance and renovation.


Emmegi spa product, as Elumatec, machines, installations and software for machining aluminum profiles, steel and PVC.

Saint Gobain is investing in India in flat glass production.

Saint-Gobain will invest around 135 million euros over the next two years to expand production capacity of its glass complex located near Chennai, the largest in India.

A third unit of flat glass production (fifth float Group in India) and a second line magnetron (coater) dedicated to the construction market will be built on this site. The plant will produce high-performance lenses, high selectivity and high efficiency using processes at the forefront of best technologies and contributing to respect for the environment.

This project strengthens the position of Saint-Gobain flat glass as a leader of high-growth Indian market and is part of the Group's strategy to increase the share of its industrial assets outside Western Europe.
