Sisal is a slender, hard cellular strand of fiber that has
demonstrated its great strength and tough resiliency in the form
of binder twine, cord and rope for many years. These same
qualities, along with its natural abrading and grease absorbing
characteristics, provide an ideal buffing wheel fabric.
A buffing wheel constructed of sisal will provide both polishing
and buffing action. For example, it is not unusual to reduce or
completely eliminate the need for fine grit, set-up polishing
wheel operations with the combined polishing and buffing
action of sisal buffs. Sisal buffs effectively remove or blend
stretcher strains, orange peel, polishing wheel grit lines,
abrasive belt lines, light die marks and other surface
imperfections from drawn, stamped and roll-formed metals.
Surface imperfections left from machine tool marks or grinding
wheel grit lines on forged parts can be removed with the use of
hard treated sisal buffs.
Sisal buffs are extensively used for finishing steel stampings
that require subsequent semi-bright or bright plating. The final
finish is enhanced by first sisalizing the base steel to a bright
luster. Moreover, the need for "color buffing" the copper or
nickel plating may be entirely eliminated.
The finishing of roll-formed, stamped or drawn stainless steel
and aluminum articles that are normally first "polished" and
then "buffed" may yield to being "sisalized" and thus result in
worthwhile savings of time, material and labor. In other
instances, multiple wheel automatic buffing machine operations
can be improved simply by installing a buff head or two of sisal
buffs in front of the cloth buffs. The objective here is to increase
the rate of cut; improve the finish; reduce the timecycle and the
number of cloth buffing wheel heads normally required to do
the job.
Sisal buffs are available in a wide variety of constructions.
There are a many applications where they can be used to
produce a more aggressive buffing action and therefore
deserve investigation on your particular buffing operations.
