Flexovit flap discs are available in a variety of specifications to cover the different needs and applications
of the market. The range offers aluminium oxide, zirconia alumina and ceramic products, with either a fibreglass
or a plastic backing plate. The discs are available in two designs, flat and conical (convex) shape. The flat form
is mainly used for face and plane surface grinding. The conical shape is used for applications on curved and more
difficult to access areas as well as for face and surface grinding.
The positioning of the flaps provide high flexibility and a constant surface finish, as well as fast stock removal,
and a very balanced all round performance. As a result of the operating speed, flap discs are particularly suitable
for rough grinding and intermediate grinding, blending and finishing. The cloth flaps are designed and positioned
to wear evenly so that new grits are exposed helping to maintain a uniform result over a long period of time.
The abrasive flaps stay sharp until the disc is completely worn out, meaning the full life of the product can be
used in each application.
The wide range of available grits and grain types mean Flexovit offers a flap disc range suitable for a variety
of applications. Coarser grits are ideally suited for applications where fast and high rates of stock removal
are needed. Finer grits offer a good balance between effective stock removal and a good surface finish.
Low set-up times, reduced noise level, comfortable and cool grinding, anti-clogging technology and the fact that
no backing-pad is required ensures excellent performance.
PREPARATION FOR USE
Damaged, misshapen or modified flap discs and back-up pads, should not be used. Always ensure that the flap
disc and the support pad are safely and centrally fixed to the machine spindle. Do not use a flap disc with
an oversize or undersize bore. The maximum peripheral operation speed and the maximum rpm of a flap disc
should not be exceeded. The spindle speed of the machine in rpm must be equal to or less than the maximum
operating speed shown on the flap disc.
