Multipoint Disc
dressers are
normally used in
small grinding
wheels on internal
grinding machines.
The diamonds are set
evenly in rows
across the face of
the disc. First
class needle shape
diamonds are used,
set in a special
sintered bonds.
Multipoint disc
dresser are
perfectly simple to
use. Its operation
is basically the
same as that of a
single point diamond
dresser except that,
after each row of
diamonds has been
used, new points can
be put into
operation simply by
rotating the disc
slightly.
An ample supply of
coolant and depth of
cut of 0.02 - 0.03
mm. max are
prerequisite for
long tool life.
Multipoint disc
dressers can be used
at any angle and
therefore in any
application.
To optimise the life
of multipoint disc
type dresser, we
recommend that the
complete disc be
turned 180o from
time to time to utilise the self
sharpening effect
produced by wear.
