Sols et Paysages

Très bel ouvrage, écrit par deux passionnés, détaillant les relations entre paysages et types de sols sur une douzaine d’exemples différents.

Ce livre écrit par deux universitaires est très agréable à lire et explique en détails les principaux types de sols que l’on trouve en Europe et leur incidence sur la végétation et l’utilisation des terrains correspondants.

Cet ouvrage décrit de façon détaillée un grand nombre de sols en croisant les observations sur le terrain, les analyses en laboratoire et en s’appuyant sur la bibliographie et l’expérience des deux auteurs. A partie de ces données sont expliquées la formation du sol et ses incidences sur la végétation et l’exploitation des terrains correspondants.

L’incidence de l’habitat, de l’agriculture, de l’exploitation du sous-sol sont prises en compte ainsi que leurs incidences sur le sol.

Une autre partie traite plus en profondeur les usages du sol qu’ils soient urbains, forestiers, agricoles, viticoles ou autres.

Ce livre est abondamment illustré de photos et croquis.

Il s’adresse à tout professionnel ou futur professionnel dans ce domaine ou dans des domaines proches (agriculture, exploitations forestières ou minières…) mais aussi à toute personne convaincue de l’importance du sol et de l’impératif de le protéger.

Very strong growth in Internet sales of wheels for mirrors machines.

Vedip, the first European web site (French origin) Internet sales of Italian wheels for mirrors machines saw its revenues for the second 2019 quarter  increased by more than 67 %.

The strategy developed by Vedip to propose, in partnership with a leading Italian manufacturers of wheels and diamond core drills for glass, very competitive prices  for working only on the Internet, detailed fact sheets with photos, standard wheels made by manufacturers / Machines / Positions, alternative wheels and a telephone support seems to meet the needs of the market in Europe mirrors.

The site already has 1741 tools now online  continues  to improve the technical data of the tools and the number of referenced machinery (over a hundred).

On Vedip you can view the data sheets (with photos and price) of the wheels for the main flat glass processing machines of the market (straight line edging machines, CNC, drills, double edger, chamfering ...) and the most important suppliers (Intermac, Bovone, Glaston, Bavelloni, Lattuada, Schiatti, JANBAC Baudin, Battelino, Denver, Bimatech, Ada, Besana, Bottero ....).

Tools and wheels for glass processing

 

The tools, mainly the wheels are very important to have a good machine working ( quality, productivity, speed..).

They are several different wheels for differents using and goals

1/Diamond wheels

This wheel must remove the glass to reach the final dimension required and give good surface conditions to prepare the polishing.

There are 2 diiferent types:

-The cup wheels ( wheels with a bowl shape) working with the top flat part

Cup diamond wheels from Lanzetta.

-The peripheral wheels working with the throat

Peripheral wheels from Bavelloni.

With cup wheels you can only obtain flat edge with arises. With peripheral wheels you can obtain all kind of edges, the shape of the throat wheels giving the shape for the glass edge.

There are segmented wheels to process laminating glass or when an important removal is required and wheels with continuous crown in other cases

 

The efficient part of the wheels is a bond where are located the diamond pieces (artificial diamond) which are able to remove glass. When a wheel needs to remove important glass quantities (from 0.2 mm up to 5 mm) a metallic bond is the best solution. To remove small glass quantities (and clean the surface after diamond wheels with metallic bonds) a bakelite bond is the right choice (from 0.01 mm and more up to 0.2 mm). These bonds are mainly used on beveling machines where the quality of the glass surface before polishing with felt and cerium oxide is very important.

Industrial diamond

A bakelite wheels is always a diamond wheels.

For the diamond the main parameters are the geometry, the grit size and the concentration inside the bond.

The secret to manufacture good diamond wheel is the right balance between the bond and the diamond parameters.

-Polishing wheels for glass and stone processing.

With these wheels you need to:

-remove from the glass surface or edge the lines let by the diamond wheels.

-polish the glass surface or edge to have a beautiful appearance

Polishing wheels from Italmole

The polishing wheels are also constituted with a bond and an abrasive material (generally aluminium oxide). The references for the grit size start with 40 (coarse grit size) and go up to 180 (very fine grit size) for the more important market suppliers.

 

-Stone wheels

There are wheels which have to remove a minimum glass quantity (in case of seams for example, or with the CNC machines) and to give in the same time a good polishing. They are done with synthetic stone.

Stone wheels from Italmole

-White wheels or Cerium wheels

These wheels are not able to remove glass but only to give a bright polishing to the glass surface or edge.
