The abrasive is a natural or synthetic substance used to wear out, polish or clean other materials - which is usually constituted by an abrasive agent (granulated abrasive) that is more or less dispersed in a glue (binder) agent. The abrasive and binders nature is very diverse and has evolved over time - from natural cements, such as Magnesite, to resin and metal binders', and abrasive agents, such as silica and corundum to super-grained diamond.
Abralux, as a producer of abrasives, provides countless materials options that can be adjusted to the equipment characteristics and, essentially, to the client's needs.
Edge abrasives consist essentially in crowns which may vary in size, in the type of
central hole or in support, and are intended to the treatment of the edges that form
the
thickness of the parts produced.
The contact with the material to be processed can be developed according to the
total
area of the edge in the straight edges or in a single straight line in the rounded
off
edges.
The Diamond Abrasives or Superabrasives, are the latest technological development
in the sector.
The binder is metallic in nature and the abrasive agent is industrial diamond, with
an
extremely long lifetime as compared to their counterparts of ligands,
predominantly magnesite, which therefore reduces sharply the machine stoppages to
replace the abrasive.
For its high cost it should be adopted a careful plan of maintenance of the
polishing
heads, because if misused, they will dramatically reduce the life of the abrasive
fickert or damage the operation in the economic point of view.
Although there are several formats of Superabrasives in the market, their economic
advantage is more pronounced in the thinning fase of the process, usually only being
used in it.
The Tangential Abrasives, commonly called "Fickert",
are produced in several different formats and correspond to the largest industrial
production, being maily used for the treatment of large surfaces.
They should be used on machines equipped with multi-abrasive polishing heads with
both
rotating and pendular movement, because the geometry of the abrasive with its
characteristic curvature on the face,
associated to the movement of the polishing heads, causes the abrasive and the
material
to contact with each other on a single line.
Regarding the Resinoid Abrasives, the binder consists of a resin
and the granular abrasive agent is usually industrial diamond.
Compared to the abrasived of magnesite origin, they have a longer
duration and a lower volume of polishing waste and, therefore, are more
and more used in the ornamental industry.
Despite its advantages, resinoid abrasives are relatively fragile and have a much
higher
cost compared to magnesite abrasives.
Radial Abrasives, similarly to the
Tangential Abrasives, are intended for treatment of large surfaces. However, they
are
used
on machines with heads that promote only rotational movement of the satellites.
The flat face geometry
of the abrasive associated with this type of movement allows the contact to develop
along a surface, being this singularity what distingwhishes them from the tangential
abrasives.
The format is usually referred, in the market, as Frankfurt, or most commonly as
Horseshoe.
Brushes are a very recent development that is growing in its use and that emerged as
an
alternative to conventional types of surface finishing of ornamental stone.
They are available in various grits and promote a type of finish that
depends on the crystal structure of the stone being treated. Depending on the
desired
effect, it is possible to achieve states of polishing and stop the process on the
thinning grits.
