Dressing is the process of putting a grinding wheel in a
condition where it is technically capable of performing grinding
operations. It fulfills the technical prerequisites for machining
the workpiece to the required surface and dimensional quality
while also taking economic aspects into account.
Conventional grinding wheels made of corundum, sintered aluminum
oxide or silicon carbide consist of a hard grainy abrading
medium which is bonded by a binder under the influence of
pore space to form a solid, abrasive "body".
Such a "body" can usually be found in grinding
processes in the form of a rapidly rotating, disc-shaped tool.
The grinding wheel must be conditioned in order to ensure
that it can indeed perform machining operations on the workpiece
with its peripheral active surface. Today the term "conditioning"
is generally used to refer to the combined processes of dressing
and cleaning grinding wheels.
These two processes serve to put the grinding wheel in an operational condition prior to its initial operation or further use.
