Manual workers have been replaced by machines in many industrial
processes. But there are still a number of complex tasks where our
mechanical systems are decidedly too clumsy. The delicate tools used
for extrusion of aluminium or plastic profiles are therefore often
polished manually.
Yet it then takes one or two days to finish the tool.
A “liquid file” - a surface polishing process of Micro Technica®
Technologies - is able to accomplish the same work in just thirty or
forty minutes.
This Surface polishing technology can be used to refine finishes of
both new EDM´ed Dies and Dies that have already been in service.
Surface polishing improved dramatically, with resultant small,
controlled radii all around the profile.
Micro Technica® Technologies AFM Process of surface polishing uses a
viscous, abrasive laden media that is flowed, under pressure, back
and forth trough a Die in a Machine Tool. The Die is often clamped
directly between the two Media cylinders in the machine but
sometimes Adaptor Plates are used also. As the Media is forced
through the Die it acts as a “Flowable Ginding Wheel” witch conforms
to the profile of the Die openings.
Key variables in this Surface polishing process are Streamer medium
type, operating pressure, surface speed and medium flow. All are
rigidly controlled for repeatability of results.
This computer control enables close tolerances to be maintained and,
because of its inherent flexibility, the process can be applied to a
wide range of Extrusion Dies.
