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.

Some information following visit Glasstec


The number of visitors seemed correct, especially Wednesday, but not at the level of the great years of Glasstec.

Exhibitor Questions It seems that the machine market continues to be difficult. Hall 16, usually completely occupied by Italian factories, was not completely filled and non-Italian stands were quite often seen.

We have seen drastic reductions in the area occupied by certain factories. The most impressive was that of Besana, very far from the great years of Besana. Macotec, the cutting table manufacturer, also reduced the area and no longer occupied a joint stand with Movetro. Even the factories which traditionally occupied impressive surfaces (Intermac, Bottero) had reduced their surface. Denver, which was growing year by year, was also on a smaller surface.

Forvet and Forel were still impressive (as was Lisec, of course, Hall 17).

Neptun continues to grow, still driven by the US market.

Bavelloni, since its acquisition by 4 of its executives continues to progress and returns to the recipes of what had made its success.

CMS presented for the first time a bilateral.

On several stands was presented a manipulator that loaded and unloaded 2 edgers positioned opposite each other.
