Heedless
of any run-out

concentric
grinding
of both cutting

is naturally
attained
due to patented
supporting
device,
as each of the two drill
lands rests
in turn
against
the same
support,
in the immediate
vicinity
of the grinding

Contrary
to
other

machines,
both cutting

can therefore
be
ground
in one set-up.
This is very time-saving,
as readjustments

are thus avoided.

When grinding
drills
with
acutangular
points,
adjust
nut l6A so that
the po~ition
of drill
support
lSA is set in such a way that
the land
of thedrLll
comes to rest
on the support
lSA. While
turning
the nut
l6A qlockwise,the
drill
support
lSA moves consequently
into
thecenteringt:ongs

by means of swinging
the

To t~ue the grinding
Vfheel,
set segment 45C at 180°.
Following
this
adjustment,
insert
the diamond dresser

set the point
of the diamond on to the angular
rest
situated
underneath the centering

Now the

How

For q~iet

Drill

Attac~e!:!tItero506
Grinding
Machine
General
The design
and construction
that
it can be employed
for
of the
grinding
point
thinning
almost
all
attachment
point
thinning
is
such
angles.
The drill
I, whilst
held in the chuck,
is removed together
with
the
collet
60 and the pivoting
fork
18A after
loosening
the spring
loaded
nut,
from the front
pivoting
device
and placed
on the point
thinning
attachment.
The position
of the main cutting
edge adjusted
for the
grinding
of the drill
point
remains
unchanged
relative
to the pivoting fork.
After
the point
thinning
operation,
it is therefore
possible to regrind
the drill
point
without
any further
adjustment
of the
position
of the drill.
The length
of the drill
must however,
protrude
rather
more from the chuck,
according
to the drill
support
of the attachment.
To allow
rapid
changing
of the chuck with
pivoting
fork
from one bearing, to the other,
we recommend operation
without
the spring
loaded
nut,
which keeps the cone of the pivoting
fork
in the bearing.
Always
ensure
that
the cone lies
concentric
in the bearing,
by careful
holding of the collet.

According

the drill

parallel

The drill

-~l?!2B:-2.f-!~!-~!!!
The drill
is clamped in a special
precision
chuck holder
with
collets
type SchKublin
B8/Art."
95, clamping
range 0,3...4
mm. The collets
are available
in steps
of 0,1 mm. The drills
are to clamp as short
as possible
according
to the point
angle.
The standard
accessories
of
this
attachment
include
one collet

-How
to
set
the
drill
After
having
clamped the drill,
loosen
the chuck clamping
nut 502-2
for chuck 507-1 and swivel
the whole unit
under the length
stop
507-7.
Thereby
the front
end of the clamping
chuck rests
against
the stop of the plate
507-6 for drill
setting.
The clamping
chucl{
with
the drill
is now to set to length
by means of the down pushed
length
stop 507-7 and the clamping
nut 502-2 slightly
tightened
so
that
the clamping
chuck can yet be turned.
Swivel
afterwards
the clamping
chucl{ under the microscope.
Thereby
the plate
507-6 centers
the chuclt according
to the reticule
in the
microscope.
The drill
cutting
edge is now to set parallel
to the
vertical
line
in the reticule.
Depending
on the expected
quantity
of material
to grind
off and the ascent
of the flute,
the grindingreserve
is to consider
on setting
the drill.
After
setting,
the clamping
nut 502-2 is to tighten,
the clamping
chuck back-moved
and the drill
put on the drill
stop in the centring
tongs.
On tightening
the friction
nut (7A) for centring
tongs
the drill
will
be properly
centered.
