2.
Construction
The
grinding
spindle
is
mounted
axially
adjustable
in a clamp-
ing
block.
It
is
driven via endless
belt
by a 3-phase
motor. The
motor
is
guarded
by a filter
against
dust
and
dirt
and
is
adjust-
able
at
the
clamping
block
by
means
of a rocker.
The
block
is
slotted
for
mounting
on
the
slide
of a machine
tool. The reduced
spindle
overhang
guarantees
precise
surface
finish.
3. External
or
internal
grinding
For these
mod
es
of
grinding
use
different pull
eys
and
driving
belts
in
order
to
attain
the
highest
possible peripheral
speed
of
the
grinding
wheel.
Moreover, external
grinding
requires
a
wheel
guard.
The
extension
spindles
on
pages 2 and 3 are
used
for
internal
grinding.
When
replacing
grinding
wheel
flange
(63)
or
extension
spindles,
MT-so
cket as
well
as
tapered
spindle
should
be
slightly
lubric
ated. When
replacing
pulley
or
grinding
wheel
take care
that
spindle
is
not
forced,
in order to
avoid
dam
age
to
ball
bearings
or
axial pla
y ,
which
impair
the
surface
finish.
4.
Connection
Check
connection
of
socket
and
earthing
conductor
(voltage
tester)
before
connecting
the
tool.
Run
tool
unload
ed
for a short
time
in
order
to check the presc
ribed
direction
of
rotation
and
to
avo
id
loosening
of
the
grinding
wheel
while
work
ing.
Further
,
check
the
running
of
the
driving belt
.
The
tension
of
the
belt
must
not
be
too
high
in
order
to
avoid
unnecessary
stress
on
or
damage
to
the
spindle
bearings.
For
external
grinding
mind
correct
adjustment
of
the
wheel
guard.
5.
Tending
the
driving
belt
Unscrew hexa
gon scr
ew
(39)
and
displace rocker with
motor
to
adjust
the
requir
ed
tension
of
the
belt. Maybe,
the
guard
(45)
should
be
adjusted;
for
this
purpose
unscr
ew h
exagon nuts
(48, 53).
6. Grinding
wheel
For
good
surface
finish
us
e for
soft
material a hard-bond
ed
wheel
for
hard
mat
eria
l a
soft-bonded
wheel
Lay
ers
of elastic
material should
be
placed

el.
In
doubt,

rate,
observe
the instructions
on

.
7.
Dressing
the
grinding
wheel
Usually
the
grinder
remains
fixed
on
the
slide
and
the
grindin
g
wheel
is
moved
uniformly to
and
fro
in
front of the
dressing tool
mount
ed
on
the
lathe. Avoid
free-hand
dress
ing
of
the
wheel
as
it
is
inaccurate
and
also
dangerous
. I
naccura
tely dressed
grinding wheels
impair
the
surface
finish.

are
protected
aga
inst
dust
and

and loss
of
grease
by
sealing
rings. Th
e tool
should
be
cleaned
thoroughly aft
er
approx.
800
duty hours
and
old
grease
should
be
remo
ved.
Rinse ball

We
recommend
to
take
