General information
3D semi-flexible abrasives.
Uniform abrasives are a new generation of abrasive products offering improved performance and efficiency. They have a uniform structure which allows consistent stock removal, and a long lifespan. This makes them a superb choice for a range of grinding and finishing tasks on stainless steel.
Convolute or unitized?
There are two types of unified abrasive:
convolute and unitized. Convolute abrasives are made by wrapping non-woven fabric around a core, and offer great
flexibility
and
durability. Unitised abrasives are constructed from layers of non-woven material, and have a uniform structure that guarantees consistent cutting performance. This makes them perfect for precision tasks. Both types of unified abrasive offer better
performance
compared to traditional abrasives.
Convolute abrasives
Convolute abrasives are a type of
3D abrasive
with a number of advantages for a wide range of applications. In particular, they are the ideal choice for tasks where you need a
softer,
flexible
tool – for example, for surface
blending
and
finishing. They achieve a much finer finish with less stock removal than their counterparts, the unitised abrasives. Another benefit of convolute abrasives is that you are less likely to cause deep scratches or pits in delicate surfaces.
In summary: convolute abrasives are a versatile, efficient abrasive tool and can be used for a range of applications where
precision
and a
high-quality
finish
are required.
Characteristics:
Soft abrasive contact for high working comfort.
Firm, uniform density.
Completely iron-free – ideal for working with stainless steel and other materials.
Flexible – adapt to the piece being worked.
Optimal balance of long lifespan, good stock removal and degree of finish.
Cooler grind.
Applications
Deburring
Cleaning
Brushing
Texturing
Satin finishing
Finishing
Removing scratches
Removing oxidation rust and deposits
Improving surface roughness
Caution!
The convolute wheels can only be used in one direction: always follow the instructions on the disc label.
Unitized abrasives
Unitised abrasives have a uniform structure and offer
consistent cutting
performance, making them perfectly suited to
precision
tasks. They are appropriate for more aggressive use cases, such as removal of
light weld
seams,
rust,
paint
and other
coatings, and
polishing
and
deburring
metal surfaces.
Unitised abrasives have a longer lifespan than their traditional counterparts, making them more
cost effective. Furthermore, as they are easier to control and produce less dust, they are a
safer
and more
environmentally
friendly choice.
Characteristics
Uniform and consistent density for a high-quality finish.
Flexible: adapt to the shape of the workpiece.
Long lifespan.
Iron-free = safe for stainless steel.
Residue-free formula leaves no smears.
Cool working avoids burn marks.
Open web structure does not get clogged with grinding dust.
Little dust generation.
Applications
Removal of weld discolouration: as well as light discolouration, unitised abrasives can easily remove deeper burn marks on the metal caused by heat production during welding.
Breaking sharp edges, deburring and rounding off corners.
Removal of TIG weld seams.
Correction of grinding defects and scratch removal: scratches on the workpiece caused by sharp objects or grinding defects due to an unsuited or overly rough abrasive can be removed with unitised material without disturbing the geometry of the workpiece.
Improving surface roughness: the pharmaceutical and food industries often have stringent requirements for the surface roughness of products. With a unitised grinding tool, the Ra value of the surface can be fine-tuned to perfection.
Removal of scoring: when workpieces have been milled, the cutter often leaves tracks behind. Unitised material can be used to finish these areas.
Removal of paint and coatings.
Removal of rust.
Pre-polishing: polishing typically requires careful preparation. Preliminary sanding with unitised material is an ideal final step before beginning on the glossy polish, and can save you a lot of time and work.
