Types of grinding wheels and tools for the processing of flat glass

 

Article written in collaboration with Dott. Renato Genocchio

 

 

There are many aspects to consider when considering a shaping operation of flat glass with diamond tools and polishing tools.

First there are the words used whose meaning can vary depending on who is talking about it.

 

The experiences of those working in this sector are different (and even contradictory in some cases) and in addition, given that there is no specific literature about it – there are only general articles in industry publications examining only the most general aspects of shaping operations – it is not easy to objectively establish a solid foundation for a common language.

 

And it is often the customers starting from their experience, sometimes passed on from generation to contradict everything the tools producers live every day.

 

So sometimes the simple naming of types of tools for glass can be a problem. It is normal, for example, called “polished” the bakelite bonded diamond wheels that have many functions other than to polish glass. It is only the wheels with synthetic binder (rubber, polyurethanes, polyesters) with abrasives such as silicon carbide, corundum and cerium oxide in which this task is allotted.

Or better, if we want to be really precise, we should speak of true polishing as in the case of cerium oxide grinding wheels, since they are an alternative to felt working with liquid cerium oxide. They only have a polishing action while the other grinding wheels with abrasive silicon carbide or aluminum oxide (corundum) have at least one double abrasive and polishing which, in the case of large particle size of the abrasive (from 40 to 80 Mesh) is undoubtedly more abrasive as polishing.

 

So we propose to classify the families of wheels for glass in 4 categories:

 

1) metal bonded Diamond wheels

2) Diamond wheels binder resin (thermosetting resins normally phenolic or melamine)

3) Circles abrasive silicon carbide, aluminum oxide or similar with synthetic binder.

4) abrasive wheels Cerium Oxide with synthetic binder

5) or compact spiral Felt, wool or synthetic, working with liquid cerium oxide.

 

The first two types of grinding work on mandrels with variable speed of rotation between 2800 and 3500 revolutions per minute while the other three working with moving pins equipped with a pressure device, and with a rotational speed between 1400 and 2800 revolutions per minute, although there are polishing wheels can work even in variable-speed mandrels.

 

Usually shaping operations are carried out without using all five types above,

 

Considering the usual working of, I would propose the following classification:

a) Bevel

b) Forming gasket on vertical or bilateral straight (cup wheels)

 

c) Shaping round seal with straight vertical or bilateral (peripheral grinding wheels)

 

d) Forming glass seal with numerical control machines

 

We will examine each case to determine generally the types of tools and the most common problems.
